c81aba8fde MIPS: Remove repetitive increase irq_err_count
commit 979934da9e ("[PATCH] mips: update IRQ handling for vr41xx") added
a function irq_dispatch, and it'll increase irq_err_count when the get_irq
callback returns a negative value, but increase irq_err_count in get_irq
was not removed.

And also, modpost complains once gpio-vr41xx drivers become modules.
  ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined!

So it would be a good idea to remove repetitive increase irq_err_count in
get_irq callback.

Fixes: 27fdd325da ("MIPS: Update VR41xx GPIO driver to use gpiolib")
Fixes: 979934da9e ("[PATCH] mips: update IRQ handling for vr41xx")

1ec6574a3c This set of changes updates init and user mode helper tasks to be
ordinary user mode tasks.
 
 In commit 40966e316f ("kthread: Ensure struct kthread is present for
 all kthreads") caused init and the user mode helper threads that call
 kernel_execve to have struct kthread allocated for them.  This struct
 kthread going away during execve in turned made a use after free of
 struct kthread possible.
 
 The commit 343f4c49f2 ("kthread: Don't allocate kthread_struct for
 init and umh") is enough to fix the use after free and is simple enough
 to be backportable.
 
 The rest of the changes pass struct kernel_clone_args to clean things
 up and cause the code to make sense.
 
 In making init and the user mode helpers tasks purely user mode tasks
 I ran into two complications.  The function task_tick_numa was
 detecting tasks without an mm by testing for the presence of
 PF_KTHREAD.  The initramfs code in populate_initrd_image was using
 flush_delayed_fput to ensuere the closing of all it's file descriptors
 was complete, and flush_delayed_fput does not work in a userspace thread.
 
 I have looked and looked and more complications and in my code review
 I have not found any, and neither has anyone else with the code sitting
 in linux-next.

54c2cc7919 USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
 5.18-rc1.  For the most part it's been a quiet development cycle for the
 USB core, but there are the usual "hot spots" of development activity.
 
 Included in here are:
 	- Thunderbolt driver updates:
 		- fixes for devices without displayport adapters
 		- lane bonding support and improvements
 		- other minor changes based on device testing
 	- dwc3 gadget driver changes.  It seems this driver will never
 	  be finished given that the IP core is showing up in zillions
 	  of new devices and each implementation decides to do something
 	  different with it...
 	- uvc gadget driver updates as more devices start to use and
 	  rely on this hardware as well
 	- usb_maxpacket() api changes to remove an unneeded and unused
 	  parameter.
 	- usb-serial driver device id updates and small cleanups
 	- typec cleanups and fixes based on device testing
 	- device tree updates for usb properties
 	- lots of other small fixes and driver updates.
 
 All of these have been in linux-next for weeks with no reported
 problems.

 several rebases before the merge window as bugs were found, so they
 remained separate.
 
 This has to touch a lot of drivers, in particular the touchscreen,

6cd6356206 mips: use __kernel_{uid,gid}32_t in uapi/asm/stat.h
Commit 8c1a381a4f ("mips: add asm/stat.h to UAPI compile-test
coverage") converted as follows:

  uid_t  -->  __kernel_uid_t
  gid_t  -->  __kernel_gid_t

The bit width of __kernel_{uid,gid}_t is 16 or 32-bits depending on
architectures.

MIPS uses 32-bits for them as in include/uapi/asm-generic/posix_types.h,
so the previous conversion is probably fine, but let's stick to the
arch-independent conversion just in case.

The safe replacements across all architectures are:

  uid_t  -->  __kernel_uid32_t
  gid_t  -->  __kernel_gid32_t

as defined in include/linux/types.h.

A similar issue was reported for the android binder. [1]

35b51afd23 RISC-V Patches for the 5.19 Merge Window, Part 1
* Support for the Svpbmt extension, which allows memory attributes to be
   encoded in pages.
 * Support for the Allwinner D1's implementation of page-based memory
   attributes.
 * Support for running rv32 binaries on rv64 systems, via the compat
   subsystem.
 * Support for kexec_file().
 * Support for the new generic ticket-based spinlocks, which allows us to
   also move to qrwlock.  These should have already gone in through the
   asm-geneic tree as well.
 * A handful of cleanups and fixes, include some larger ones around
   atomics and XIP.

6b0e34a030 Mainly driver updates this time around. There's a single patch to the core clk
framework that simplifies a runtime PM call. Otherwise the majority of the diff
 falls to a few SoC drivers: Qualcomm, STM32 and MediaTek. Those SoCs gain some
 new hardware support and what comes along with that is quite a few lines of
 data and some clk_ops code. Beyond the new hardware support we have the usual
 pile of driver updates that add missing clks on already supported SoCs or fix
 up problems like bad clk tree descriptions. It's nice to see that more drivers
 are moving to clk_hw based APIs too.
 
 New Drivers:
  - Add STM32MP13 RCC driver (Reset Clock Controller)
  - MediaTek MT8186 SoC clk support
  - Airoha EN7523 SoC system clocks
  - Clock driver for exynosautov9 SoC
  - Renesas R-Car V4H and RZ/V2M SoCs
  - Renesas RZ/G2UL SoC
  - LPASS clk driver for Qualcomm sc7280 SoC
  - GCC clk driver for Qualcomm SC8280XP SoC
 
 Updates:
  - SDCC uses floor clk ops on Qualcomm MSM8976
  - Add modem reset and fix RPM clks on Qualcomm MSM8976
  - Add the two missing CLKOUT clocks for U8500/DB8500 SoC
  - Mark some clks critical on Ingenic X1000
  - Convert ux500 to clk_hw
  - Move MediaTek driver to clk_hw provider APIs
  - Use i2c driver probe_new to avoid id scans
  - Convert a number of Rockchip dt bindings to YAML
  - Mark hclk_vo critical on Rockchip rk3568
  - Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage
  - Various cleanups like memory allocation error checks and plugged leaks
  - Allwinner H6 RTC clock support
  - Allwinner H616 32 kHz clock support
  - Add the Universal Flash Storage clock on Renesas R-Car S4-8
  - Add I2C, SSIF-2 (sound), USB, CANFD, OSTM (timer), WDT, SPI Multi
    I/O Bus, RSPI, TSU (thermal), and ADC clocks and resets on Renesas RZ/G2UL
  - Add display clock support on Renesas RZ/G2L
  - Add RPC (QSPI/HyperFlash) clocks on Renesas R-Car E3 and D3
  - Add 27 MHz phy PLL ref clock on i.MX
  - Add mcore_booted module parameter to tell kernel M core has already booted
    for i.MX
  - Remove snvs clock on i.MX because it was for secure world only
  - Add dt bindings for i.MX8MN GPT
  - Add DISP2 pixel clock for i.MX8MP
  - Add clkout1/2 for i.MX8MP
  - Fix parent clock of ubs_root_clk for i.MX8MP
  - Implement better RCG parking on Qualcomm SoCs using the shared RCG clk ops

16477cdfef asm-generic changes for 5.19
The asm-generic tree contains three separate changes for linux-5.19:
 
 - The h8300 architecture is retired after it has been effectively
   unmaintained for a number of years. This is the last architecture we
   supported that has no MMU implementation, but there are still a few
   architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
   and without an MMU.
 
 - A series to add a generic ticket spinlock that can be shared by most
   architectures with a working cmpxchg or ll/sc type atomic, including
   the conversion of riscv, csky and openrisc. This series is also a
   prerequisite for the loongarch64 architecture port that will come as
   a separate pull request.
 
 - A cleanup of some exported uapi header files to ensure they can be
   included from user space without relying on other kernel headers.

7e4fd16b38 MIPS: RALINK: Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC
kernel test robot reports a build error used with clang compiler and
mips-randconfig [1]:

    ld.lld: error: undefined symbol: pci_remap_iospace

we can see the following configs in the mips-randconfig file:

    CONFIG_RALINK=y
    CONFIG_SOC_MT7620=y
    CONFIG_PCI_DRIVERS_LEGACY=y
    CONFIG_PCI=y

CONFIG_RALINK is set, so pci_remap_iospace is defined in the related
arch/mips/include/asm/mach-ralink/spaces.h header file:

    #define pci_remap_iospace pci_remap_iospace

CONFIG_PCI is set, so pci_remap_iospace() in drivers/pci/pci.c is not
built due to pci_remap_iospace is defined under CONFIG_RALINK.

    #ifndef pci_remap_iospace
    int pci_remap_iospace(const struct resource *res, ...)

    $ objdump -d drivers/pci/pci.o | grep pci_remap_iospace
    00004cc8 <devm_pci_remap_iospace>:
        4d18:	10400008 	beqz	v0,4d3c <devm_pci_remap_iospace+0x74>
        4d2c:	1040000c 	beqz	v0,4d60 <devm_pci_remap_iospace+0x98>
        4d70:	1000fff3 	b	4d40 <devm_pci_remap_iospace+0x78>

In addition, CONFIG_PCI_DRIVERS_GENERIC is not set, so pci_remap_iospace()
in arch/mips/pci/pci-generic.c is not built too.

    #ifdef pci_remap_iospace
    int pci_remap_iospace(const struct resource *res, ...)

For the above reasons, undefined reference pci_remap_iospace() looks like
reasonable.

Here are simple steps to reproduce used with gcc and defconfig:

    cd mips.git
    make vocore2_defconfig # set RALINK, SOC_MT7620, PCI_DRIVERS_LEGACY
    make menuconfig        # set PCI
    make

there exists the following build error:

      LD      vmlinux.o
      MODPOST vmlinux.symvers
      MODINFO modules.builtin.modinfo
      GEN     modules.builtin
      LD      .tmp_vmlinux.kallsyms1
    drivers/pci/pci.o: In function `devm_pci_remap_iospace':
    pci.c:(.text+0x4d24): undefined reference to `pci_remap_iospace'
    Makefile:1158: recipe for target 'vmlinux' failed
    make: *** [vmlinux] Error 1

Define pci_remap_iospace under CONFIG_PCI_DRIVERS_GENERIC can fix the build
error, with this patch, no build error remains. This patch is similar with
commit e538e86498 ("MIPS: asm: pci: define arch-specific
'pci_remap_iospace()' dependent on 'CONFIG_PCI_DRIVERS_GENERIC'").

7e062cda7d Networking changes for 5.19.
Core
 ----
 
  - Support TCPv6 segmentation offload with super-segments larger than
    64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
 
  - Generalize skb freeing deferral to per-cpu lists, instead of
    per-socket lists.
 
  - Add a netdev statistic for packets dropped due to L2 address
    mismatch (rx_otherhost_dropped).
 
  - Continue work annotating skb drop reasons.
 
  - Accept alternative netdev names (ALT_IFNAME) in more netlink
    requests.
 
  - Add VLAN support for AF_PACKET SOCK_RAW GSO.
 
  - Allow receiving skb mark from the socket as a cmsg.
 
  - Enable memcg accounting for veth queues, sysctl tables and IPv6.
 
 BPF
 ---
 
  - Add libbpf support for User Statically-Defined Tracing (USDTs).
 
  - Speed up symbol resolution for kprobes multi-link attachments.
 
  - Support storing typed pointers to referenced and unreferenced
    objects in BPF maps.
 
  - Add support for BPF link iterator.
 
  - Introduce access to remote CPU map elements in BPF per-cpu map.
 
  - Allow middle-of-the-road settings for the
    kernel.unprivileged_bpf_disabled sysctl.
 
  - Implement basic types of dynamic pointers e.g. to allow for
    dynamically sized ringbuf reservations without extra memory copies.
 
 Protocols
 ---------
 
  - Retire port only listening_hash table, add a second bind table
    hashed by port and address. Avoid linear list walk when binding
    to very popular ports (e.g. 443).
 
  - Add bridge FDB bulk flush filtering support allowing user space
    to remove all FDB entries matching a condition.
 
  - Introduce accept_unsolicited_na sysctl for IPv6 to implement
    router-side changes for RFC9131.
 
  - Support for MPTCP path manager in user space.
 
  - Add MPTCP support for fallback to regular TCP for connections
    that have never connected additional subflows or transmitted
    out-of-sequence data (partial support for RFC8684 fallback).
 
  - Avoid races in MPTCP-level window tracking, stabilize and improve
    throughput.
 
  - Support lockless operation of GRE tunnels with seq numbers enabled.
 
  - WiFi support for host based BSS color collision detection.
 
  - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

32c53420d2 eth: de4x5: remove support for Generic DECchip & DIGITAL EtherWORKS PCI/EISA
Looks like almost all changes to this driver had been tree-wide
refactoring since git era begun. There is one commit from Al
15 years ago which could potentially be fixing a real bug.

The driver is using virt_to_bus() and is a real magnet for pointless
cleanups. It seems unlikely to have real users. Let's try to shed
this maintenance burden.

84aa85108b MIPS: Rewrite `csum_tcpudp_nofold' in plain C
Recent commit 198688edbf ("MIPS: Fix inline asm input/output type
mismatch in checksum.h used with Clang") introduced a code size and
performance regression with 64-bit code emitted for `csum_tcpudp_nofold'
by GCC, caused by a redundant truncation operation produced due to a
data type change made to the variable associated with the inline
assembly's output operand.

The intent previously expressed here with operands and constraints for
optimal code was to have the output operand share a register with one
inputs, both of a different integer type each.  This is perfectly valid
with the MIPS psABI where a register can hold integer data of different
types and the assembly code used here makes data stored in the output
register match the data type used with the output operand, however it
has turned out impossible to express this arrangement in source code
such as to satisfy LLVM, apparently due to the compiler's internal
limitations.

There is nothing peculiar about the inline assembly `csum_tcpudp_nofold'
includes however, though it does choose assembly instructions carefully.

Rewrite this piece of assembly in plain C then, using corresponding C
language operations, making GCC produce the same assembly instructions,
possibly shuffled, in the general case and sometimes actually fewer of
them where an input is constant, because the compiler does not have to
reload it to a register (operand constraints could be adjusted for that,
but the plain C approach is cleaner anyway).

Example code size changes are as follows, for a 32-bit configuration:

      text       data        bss      total filename
   5920480    1347236     126592    7394308 vmlinux-old
   5920480    1347236     126592    7394308 vmlinux-now
   5919728    1347236     126592    7393556 vmlinux-c

and for a 64-bit configuration:

      text       data        bss      total filename
   6024112    1790828     225728    8040668 vmlinux-old
   6024128    1790828     225728    8040684 vmlinux-now
   6023760    1790828     225728    8040316 vmlinux-c

respectively, where "old" is with the commit referred reverted, "now" is
with no change, and "c" is with this change applied.

ae07562909 mm: change huge_ptep_clear_flush() to return the original pte
Patch series "Fix CONT-PTE/PMD size hugetlb issue when unmapping or migrating", v4.

presently, migrating a hugetlb page or unmapping a poisoned hugetlb page,
we'll use ptep_clear_flush() and set_pte_at() to nuke the page table entry
and remap it, and this is incorrect for CONT-PTE or CONT-PMD size hugetlb
page, which will cause potential data consistent issue.  This patch set
will change to use hugetlb related APIs to fix this issue.

Note: Mike pointed out the huge_ptep_get() will only return the one
specific value, and it would not take into account the dirty or young bits
of CONT-PTE/PMDs like the huge_ptep_get_and_clear() [1].  This
inconsistent issue is not introduced by this patch set, and this issue
will be addressed in another thread [2].  Meanwhile the uffd for hugetlb
case [3] pointed out by Gerald also needs another patch to address.

This patch (of 3):

It is incorrect to use ptep_clear_flush() to nuke a hugetlb page table
when unmapping or migrating a hugetlb page, and will change to use
huge_ptep_clear_flush() instead in the following patches.

So this is a preparation patch, which changes the huge_ptep_clear_flush()
to return the original pte to help to nuke a hugetlb page table.

1c99c6a7c3 mips: use fallback for random_get_entropy() instead of just c0 random
For situations in which we don't have a c0 counter register available,
we've been falling back to reading the c0 "random" register, which is
usually bounded by the amount of TLB entries and changes every other
cycle or so. This means it wraps extremely often. We can do better by
combining this fast-changing counter with a potentially slower-changing
counter from random_get_entropy_fallback() in the more significant bits.
This commit combines the two, taking into account that the changing bits
are in a different bit position depending on the CPU model. In addition,
we previously were falling back to 0 for ancient CPUs that Linux does
not support anyway; remove that dead path entirely.

The errors can be fixed by prefixing the types with __kernel_.

Then, remove the no-header-test entry from user/include/Makefile.

f5e2d8186d MIPS: Use NOKPROBE_SYMBOL() instead of __kprobes annotation
If define CONFIG_KPROBES, __kprobes annotation forces the whole function
into the ".kprobes.text" section, NOKPROBE_SYMBOL() only stores the given
function address in the "_kprobe_blacklist" section which is introduced
to maintain kprobes blacklist.

Modify the related code to use NOKPROBE_SYMBOL() to protect functions from
kprobes instead of __kprobes annotation under arch/mips.

No obvious functional change in this patch, some more work needs to be done
to fix the kernel panic when execute the following testcase on mips:

  # cd tools/testing/selftests/ftrace
  # ./ftracetest test.d/kprobe/multiple_kprobes.tc

84595f450a MIPS: smp: optimization for flush_tlb_mm when exiting
When process exits or execute new binary, it will call function
exit_mmap with old mm, there is such function call trace:
  exit_mmap(struct mm_struct *mm)
      --> tlb_finish_mmu(&tlb, 0, -1)
         --> arch_tlb_finish_mmu(tlb, start, end, force)
	    --> tlb_flush_mmu(tlb);
               --> tlb_flush(struct mmu_gather *tlb)
                  --> flush_tlb_mm(tlb->mm)

It is not necessary to flush tlb since oldmm is not used anymore
by the process, there is similar operations on IA64/ARM64 etc,
this patch adds such optimization on MIPS.

5bd2e97c86 fork: Generalize PF_IO_WORKER handling
Add fn and fn_arg members into struct kernel_clone_args and test for
them in copy_thread (instead of testing for PF_KTHREAD | PF_IO_WORKER).
This allows any task that wants to be a user space task that only runs
in kernel mode to use this functionality.

The code on x86 is an exception and still retains a PF_KTHREAD test
because x86 unlikely everything else handles kthreads slightly
differently than user space tasks that start with a function.

The functions that created tasks that start with a function
have been updated to set ".fn" and ".fn_arg" instead of
".stack" and ".stack_size".  These functions are fork_idle(),
create_io_thread(), kernel_thread(), and user_mode_thread().

c5febea095 fork: Pass struct kernel_clone_args into copy_thread
With io_uring we have started supporting tasks that are for most
purposes user space tasks that exclusively run code in kernel mode.

The kernel task that exec's init and tasks that exec user mode
helpers are also user mode tasks that just run kernel code
until they call kernel execve.

Pass kernel_clone_args into copy_thread so these oddball
tasks can be supported more cleanly and easily.
