27bc50fc90 - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative
   reports (or any positive ones, come to that).
 
 - Also the Maple Tree from Liam R.  Howlett.  An overlapping range-based
   tree for vmas.  It it apparently slight more efficient in its own right,
   but is mainly targeted at enabling work to reduce mmap_lock contention.
 
   Liam has identified a number of other tree users in the kernel which
   could be beneficially onverted to mapletrees.
 
   Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
   (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com).
   This has yet to be addressed due to Liam's unfortunately timed
   vacation.  He is now back and we'll get this fixed up.
 
 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.  It uses
   clang-generated instrumentation to detect used-unintialized bugs down to
   the single bit level.
 
   KMSAN keeps finding bugs.  New ones, as well as the legacy ones.
 
 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
   memory into THPs.
 
 - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support
   file/shmem-backed pages.
 
 - userfaultfd updates from Axel Rasmussen
 
 - zsmalloc cleanups from Alexey Romanov
 
 - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure
 
 - Huang Ying adds enhancements to NUMA balancing memory tiering mode's
   page promotion, with a new way of detecting hot pages.
 
 - memcg updates from Shakeel Butt: charging optimizations and reduced
   memory consumption.
 
 - memcg cleanups from Kairui Song.
 
 - memcg fixes and cleanups from Johannes Weiner.
 
 - Vishal Moola provides more folio conversions
 
 - Zhang Yi removed ll_rw_block() :(
 
 - migration enhancements from Peter Xu

 - Aneesh Kumar added ability for a device driver to alter the memory
   tiering promotion paths.  For optimizations by PMEM drivers, DRM
   drivers, etc.

Merge tag 'x86_mm_for_v6.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 mm updates from Dave Hansen:
 "There are some small things here, plus one big one.

  The big one detected and refused to create W+X kernel mappings. This
  caused a bit of trouble and it is entirely disabled on 32-bit due to
  known unfixable EFI issues. It also oopsed on some systemd eBPF use,
  which kept some users from booting.

  The eBPF issue is fixed, but those troubles were caught relatively
  recently which made me nervous that there are more lurking. The final
  commit in here retains the warnings, but doesn't actually refuse to
  create W+X mappings.

  Summary:

   - Detect insecure W+X mappings and warn about them, including a few
     bug fixes and relaxing the enforcement

   - Do a long-overdue defconfig update and enabling W+X boot-time
     detection

   - Cleanup _PAGE_PSE handling (follow-up on an earlier bug)

   - Rename a change_page_attr function"

d4013bc4d4 bitmap patches for v6.1-rc1
From Phil Auld:
 drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES
 
 From me:
 cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
 
 This series cleans that mess and adds new config FORCE_NR_CPUS that
 allows to optimize cpumask subsystem if the number of CPUs is known
 at compile-time.
 
 From me:
 lib: optimize find_bit() functions
 
 Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
 
 From me:
 lib/find: add find_nth_bit()
 
 Adds find_nth_bit(), which is ~70 times faster than bitcounting with
 for_each() loop:
         for_each_set_bit(bit, mask, size)
                 if (n-- == 0)
                         return bit;
 
 Also adds bitmap_weight_and() to let people replace this pattern:
 	tmp = bitmap_alloc(nbits);
 	bitmap_and(tmp, map1, map2, nbits);
 	weight = bitmap_weight(tmp, nbits);
 	bitmap_free(tmp);
 with a single bitmap_weight_and() call.
 
 From me:
 cpumask: repair cpumask_check()
 
 After switching cpumask to use nr_cpu_ids, cpumask_check() started
 generating many false-positive warnings. This series fixes it.
 
 From Valentin Schneider:
 bitmap,cpumask: Add for_each_cpu_andnot() and for_each_cpu_andnot()
 
 Extends the API with one more function and applies it in sched/core.

cdf072acb5 Tracing updates for 6.1:
Major changes:
 
  - Changed location of tracing repo from personal git repo to:
    git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git
 
  - Added Masami Hiramatsu as co-maintainer
 
  - Updated MAINTAINERS file to separate out FTRACE as it is
    more than just TRACING.
 
 Minor changes:
 
  - Added Mark Rutland as FTRACE reviewer
 
  - Updated user_events to make it on its way to remove the BROKEN tag.
    The changes should now be acceptable but will run it through
    a cycle and hopefully we can remove the BROKEN tag next release.
 
  - Added filtering to eprobes
 
  - Added a delta time to the benchmark trace event
 
  - Have the histogram and filter callbacks called via a switch
    statement instead of indirect functions. This speeds it up to
    avoid retpolines.
 
  - Add a way to wake up ring buffer waiters waiting for the
    ring buffer to fill up to its watermark.
 
  - New ioctl() on the trace_pipe_raw file to wake up ring buffer
    waiters.
 
  - Wake up waiters when the ring buffer is disabled.
    A reader may block when the ring buffer is disabled,
    but if it was blocked when the ring buffer is disabled
    it should then wake up.
 
 Fixes:
 
  - Allow splice to read partially read ring buffer pages
    Fixes splice never moving forward.
 
  - Fix inverted compare that made the "shortest" ring buffer
    wait queue actually the longest.
 
  - Fix a race in the ring buffer between resetting a page when
    a writer goes to another page, and the reader.
 
  - Fix ftrace accounting bug when function hooks are added at
    boot up before the weak functions are set to "disabled".
 
  - Fix bug that freed a user allocated snapshot buffer when
    enabling a tracer.
 
  - Fix possible recursive locks in osnoise tracer
 
  - Fix recursive locking direct functions
 
  - And other minor clean ups and fixes

385f4a1019 Modules changes for v6.1-rc1
There's only two pathes queued up for v6.1 for modules, these have
 been grinding on linux-next for at least 4 weeks now:
 
   * David Disseldorp's minor enhancement for sysfs compression string
   * Aaron Tomlin's debugfs interface to view unloaded tainted modules
 
 But there are other changes queued up for testing for the next merge
 window already. One change being still discussed, and *not* yet even close
 to testing on linux-next, but worth mentioning to put on your radar is
 the generalization of the bpf prog_pack thing. The idea with that is to
 generalize the iTLB gains seen with using huge pages on eBPF to other text
 uses on the kernel (modules, ftrace, kprobes). Song Liu is doing a good job
 following up on that difficult task as the semantics for the special
 permissions are crap, and it really hasn't been easy to put all this
 together. The latest effort can be read on his vmalloc_exec() patch
 series [0].
 
 Aaron will have a fix posted soon for the debugfs interface for unloaded
 modules, when that comes I'll just bounce that to you as it should be
 merged.

Merge tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator updates from Jason Donenfeld:

 - Huawei reported that when they updated their kernel from 4.4 to
   something much newer, some userspace code they had broke, the culprit
   being the accidental removal of O_NONBLOCK from /dev/random way back
   in 5.6. It's been gone for over 2 years now and this is the first
   we've heard of it, but userspace breakage is userspace breakage, so
   O_NONBLOCK is now back.

 - Use randomness from hardware RNGs much more often during early boot,
   at the same interval that crng reseeds are done, from Dominik.

 - A semantic change in hardware RNG throttling, so that the hwrng
   framework can properly feed random.c with randomness from hardware
   RNGs that aren't specifically marked as creditable.

   A related patch coming to you via Herbert's hwrng tree depends on
   this one, not to compile, but just to function properly, so you may
   want to merge this PULL before that one.

 - A fix to clamp credited bits from the interrupts pool to the size of
   the pool sample. This is mainly just a theoretical fix, as it'd be
   pretty hard to exceed it in practice.

 - Oracle reported that InfiniBand TCP latency regressed by around
   10-15% after a change a few cycles ago made at the request of the RT
   folks, in which we hoisted a somewhat rare operation (1 in 1024
   times) out of the hard IRQ handler and into a workqueue, a pretty
   common and boring pattern.

   It turns out, though, that scheduling a worker from there has
   overhead of its own, whereas scheduling a timer on that same CPU for
   the next jiffy amortizes better and doesn't incur the same overhead.

   I also eliminated a cache miss by moving the work_struct (and
   subsequently, the timer_list) to below a critical cache line, so that
   the more critical members that are accessed on every hard IRQ aren't
   split between two cache lines.

 - The boot-time initialization of the RNG has been split into two
   approximate phases: what we can accomplish before timekeeping is
   possible and what we can accomplish after.

   This winds up being useful so that we can use RDRAND to seed the RNG
   before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in
   addition to other early uses of randomness. The effect is that
   systems with RDRAND (or a bootloader seed) will never see any
   warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And
   kfence benefits from getting a better seed of its own.

 - Small systems without much entropy sometimes wind up putting some
   truncated serial number read from flash into hostname, so contribute
   utsname changes to the RNG, without crediting.

 - Add smaller batches to serve requests for smaller integers, and make
   use of them when people ask for random numbers bounded by a given
   compile-time constant. This has positive effects all over the tree,
   most notably in networking and kfence.

 - The original jitter algorithm intended (I believe) to schedule the
   timer for the next jiffy, not the next-next jiffy, yet it used
   mod_timer(jiffies + 1), which will fire on the next-next jiffy,
   instead of what I believe was intended, mod_timer(jiffies), which
   will fire on the next jiffy. So fix that.

 - Fix a comment typo, from William.

Merge tag 'slab-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab fixes from Vlastimil Babka:

 - The "common kmalloc v4" series [1] by Hyeonggon Yoo.

   While the plan after LPC is to try again if it's possible to get rid
   of SLOB and SLAB (and if any critical aspect of those is not possible
   to achieve with SLUB today, modify it accordingly), it will take a
   while even in case there are no objections.

   Meanwhile this is a nice cleanup and some parts (e.g. to the
   tracepoints) will be useful even if we end up with a single slab
   implementation in the future:

      - Improves the mm/slab_common.c wrappers to allow deleting
        duplicated code between SLAB and SLUB.

      - Large kmalloc() allocations in SLAB are passed to page allocator
        like in SLUB, reducing number of kmalloc caches.

      - Removes the {kmem_cache_alloc,kmalloc}_node variants of
        tracepoints, node id parameter added to non-_node variants.

 - Addition of kmalloc_size_roundup()

   The first two patches from a series by Kees Cook [2] that introduce
   kmalloc_size_roundup(). This will allow merging of per-subsystem
   patches using the new function and ultimately stop (ab)using ksize()
   in a way that causes ongoing trouble for debugging functionality and
   static checkers.

 - Wasted kmalloc() memory tracking in debugfs alloc_traces

   A patch from Feng Tang that enhances the existing debugfs
   alloc_traces file for kmalloc caches with information about how much
   space is wasted by allocations that needs less space than the
   particular kmalloc cache provides.

 - My series [3] to fix validation races for caches with enabled
   debugging:

      - By decoupling the debug cache operation more from non-debug
        fastpaths, extra locking simplifications were possible and thus
        done afterwards.

      - Additional cleanup of PREEMPT_RT specific code on top, by Thomas
        Gleixner.

      - A late fix for slab page leaks caused by the series, by Feng
        Tang.

 - Smaller fixes and cleanups:

      - Unneeded variable removals, by ye xingchen

      - A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu

7f6dcffb44 Preempt RT cleanups:
Introduce preempt_[dis|enable_nested() and use it to clean up
  various places which have open coded PREEMPT_RT conditionals.
 
  On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither disabling
  preemption nor interrupts. Though there are a few places which depend on
  the implicit preemption/interrupt disable of those locks, e.g. seqcount
  write sections, per CPU statistics updates etc.
 
  PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to
  disable/enable preemption in the related code parts all over the
  place. That's hard to read and does not really explain why this is
  necessary.
 
  Linus suggested to use helper functions (preempt_disable_nested() and
  preempt_enable_nested()) and use those in the affected places. On !RT
  enabled kernels these functions are NOPs, but contain a lockdep assert to
  validate that preemption is actually disabled to catch call sites which
  do not have preemption disabled.
 
  Clean up the affected code paths in mm, dentry and lib.

493ffd6605 ucounts: Split rlimit and ucount values and max values
After the ucount rlimit code was merged a bunch of small but
 siginificant bugs were found and fixed.  At the time it was realized
 that part of the problem was that while the ucount rlimits were very
 similar to the oridinary ucounts (in being nested counts with limits)
 the semantics were slightly different and the code would be less error
 prone if there was less sharing.  This is the long awaited cleanup
 that should hopefully keep things more comprehensible and less error
 prone for whoever needs to touch that code next.

e572410e47 ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Recently I had a conversation where it was pointed out to me that
 SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
 difficult for a tracer to handle.
 
 Keeping SIGKILL working after the process has been killed is pain
 from an implementation point of view.
 
 So since the debuggers don't want this behavior let's see if we can
 remove this wart for the userspace API
 
 If a regression is detected it should only need to be the last change
 that is the reverted.  The other two are just general cleanups that
 make the last patch simpler.

ef688f8b8c The first batch of KVM patches, mostly covering x86, which I
am sending out early due to me travelling next week.  There is a
 lone mm patch for which Andrew gave an informal ack at
 https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org.
 
 I will send the bulk of ARM work, as well as other
 architectures, at the end of next week.
 
 ARM:
 
 * Account stage2 page table allocations in memory stats.
 
 x86:
 
 * Account EPT/NPT arm64 page table allocations in memory stats.
 
 * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses.
 
 * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of
   Hyper-V now support eVMCS fields associated with features that are
   enumerated to the guest.
 
 * Use KVM's sanitized VMCS config as the basis for the values of nested VMX
   capabilities MSRs.
 
 * A myriad event/exception fixes and cleanups.  Most notably, pending
   exceptions morph into VM-Exits earlier, as soon as the exception is
   queued, instead of waiting until the next vmentry.  This fixed
   a longstanding issue where the exceptions would incorrecly become
   double-faults instead of triggering a vmexit; the common case of
   page-fault vmexits had a special workaround, but now it's fixed
   for good.
 
 * A handful of fixes for memory leaks in error paths.
 
 * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow.
 
 * Never write to memory from non-sleepable kvm_vcpu_check_block()
 
 * Selftests refinements and cleanups.
 
 * Misc typo cleanups.
 
 Generic:
 
 * remove KVM_REQ_UNHALT

Merge tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi

Pull EFI updates from Ard Biesheuvel:
 "A bit more going on than usual in the EFI subsystem. The main driver
  for this has been the introduction of the LoonArch architecture last
  cycle, which inspired some cleanup and refactoring of the EFI code.
  Another driver for EFI changes this cycle and in the future is
  confidential compute.

  The LoongArch architecture does not use either struct bootparams or DT
  natively [yet], and so passing information between the EFI stub and
  the core kernel using either of those is undesirable. And in general,
  overloading DT has been a source of issues on arm64, so using DT for
  this on new architectures is a to avoid for the time being (even if we
  might converge on something DT based for non-x86 architectures in the
  future). For this reason, in addition to the patch that enables EFI
  boot for LoongArch, there are a number of refactoring patches applied
  on top of which separate the DT bits from the generic EFI stub bits.
  These changes are on a separate topich branch that has been shared
  with the LoongArch maintainers, who will include it in their pull
  request as well. This is not ideal, but the best way to manage the
  conflicts without stalling LoongArch for another cycle.

  Another development inspired by LoongArch is the newly added support
  for EFI based decompressors. Instead of adding yet another
  arch-specific incarnation of this pattern for LoongArch, we are
  introducing an EFI app based on the existing EFI libstub
  infrastructure that encapulates the decompression code we use on other
  architectures, but in a way that is fully generic. This has been
  developed and tested in collaboration with distro and systemd folks,
  who are eager to start using this for systemd-boot and also for arm64
  secure boot on Fedora. Note that the EFI zimage files this introduces
  can also be decompressed by non-EFI bootloaders if needed, as the
  image header describes the location of the payload inside the image,
  and the type of compression that was used. (Note that Fedora's arm64
  GRUB is buggy [0] so you'll need a recent version or switch to
  systemd-boot in order to use this.)

  Finally, we are adding TPM measurement of the kernel command line
  provided by EFI. There is an oversight in the TCG spec which results
  in a blind spot for command line arguments passed to loaded images,
  which means that either the loader or the stub needs to take the
  measurement. Given the combinatorial explosion I am anticipating when
  it comes to firmware/bootloader stacks and firmware based attestation
  protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
  when it comes to EFI measured boot, which is that the kernel measures
  the initrd and command line. Intermediate loaders can measure
  additional assets if needed, but with the baseline in place, we can
  deploy measured boot in a meaningful way even if you boot into Linux
  straight from the EFI firmware.

  Summary:

   - implement EFI boot support for LoongArch

   - implement generic EFI compressed boot support for arm64, RISC-V and
     LoongArch, none of which implement a decompressor today

   - measure the kernel command line into the TPM if measured boot is in
     effect

   - refactor the EFI stub code in order to isolate DT dependencies for
     architectures other than x86

   - avoid calling SetVirtualAddressMap() on arm64 if the configured
     size of the VA space guarantees that doing so is unnecessary

   - unmap kernel code from the x86 mixed mode 1:1 page tables"

bdc753c7fc Here's the main clk pull request for this merge window. We have some
late breaking reports that a patch series to rework clk rate range
 support broke boot on some devices, so I've left that branch out of this
 PR. Hopefully we can get to that next week, or punt on it and let it
 bake another cycle. That means we don't really have any changes to the
 core framework this time around besides a few typo fixes. Instead this
 is all clk driver updates and fixes.
 
 The usual suspects are here (again), with Qualcomm dominating the
 diffstat. We look to have gained support for quite a few new Qualcomm
 SoCs and Dmitry worked on updating many of the existing Qualcomm drivers
 to use clk_parent_data. After that we have MediaTek drivers getting some
 much needed updates, in particular to support GPU DVFS. There are also
 quite a few Samsung clk driver patches, but that's mostly because there
 was a maintainer change and so last release we missed some of those
 patches.
 
 Overall things look normal, but I'm slowly reviewing core framework code
 nowadays and that shows given the rate range patches had to be yanked
 last minute. Let's hope this situation changes soon.
 
 New Drivers:
  - Support for Renesas VersaClock7 clock generator family
  - Add Spreadtrum UMS512 SoC clk support
  - New clock drivers for MediaTek Helio X10 MT6795
  - Display clks for Qualcomm SM6115, SM8450
  - GPU clks for Qualcomm SC8280XP
  - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers
 
 Deleted Drivers:
  - Remove DaVinci DM644x and DM646x clk driver support
 
 Updates:
  - Convert Baikal-T1 CCU driver to platform driver
  - Split reset support out of primary Baikal-T1 CCU driver
  - Add some missing clks required for RPiVid Video Decoder on RaspberryPi
  - Mark PLLC critical on bcm2835
  - More devm helpers for fixed rate registration
  - Various PXA168 clk driver fixes
  - Add resets for MediaTek MT8195 PCIe and USB

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "We have some late breaking reports that a patch series to rework clk
  rate range support broke boot on some devices, so I've left that
  branch out of this. Hopefully we can get to that next week, or punt on
  it and let it bake another cycle. That means we don't really have any
  changes to the core framework this time around besides a few typo
  fixes. Instead this is all clk driver updates and fixes.

  The usual suspects are here (again), with Qualcomm dominating the
  diffstat. We look to have gained support for quite a few new Qualcomm
  SoCs and Dmitry worked on updating many of the existing Qualcomm
  drivers to use clk_parent_data. After that we have MediaTek drivers
  getting some much needed updates, in particular to support GPU DVFS.
  There are also quite a few Samsung clk driver patches, but that's
  mostly because there was a maintainer change and so last release we
  missed some of those patches.

  Overall things look normal, but I'm slowly reviewing core framework
  code nowadays and that shows given the rate range patches had to be
  yanked last minute. Let's hope this situation changes soon.

  New Drivers:
   - Support for Renesas VersaClock7 clock generator family
   - Add Spreadtrum UMS512 SoC clk support
   - New clock drivers for MediaTek Helio X10 MT6795
   - Display clks for Qualcomm SM6115, SM8450
   - GPU clks for Qualcomm SC8280XP
   - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers

   - Split reset support out of primary Baikal-T1 CCU driver
   - Add some missing clks required for RPiVid Video Decoder on
     RaspberryPi
   - Mark PLLC critical on bcm2835
   - More devm helpers for fixed rate registration
   - Various PXA168 clk driver fixes

3002b7a318 Staging driver changes for 6.1-rc1
Here is the large set of staging driver changes for 6.1-rc1.
 
 Nothing really interesting in here at all except we deleted a driver
 (fwserial) as no one had been using it for a long time.  Other than
 that, just the normal cleanups and minor fixes:
   - rtl8723bs driver cleanups
   - loads of r8188eu driver cleanups, making the driver smaller and
     fixing up some firmware dependency issues.
   - vt6655 driver cleanups.
   - lots of other small staging driver cleanups.
 
 All of these have been in linux-next for a while with no reported
 issues.
