7ba167c4c7 netfs: Switch to using unsigned long long rather than loff_t
Switch to using unsigned long long rather than loff_t in netfslib to avoid
problems with the sign flipping in the maths when we're dealing with the
byte at position 0x7fffffffffffffff.

74e797d79c mm: Provide a means of invalidation without using launder_folio
Implement a replacement for launder_folio.  The key feature of
invalidate_inode_pages2() is that it locks each folio individually, unmaps
it to prevent mmap'd accesses interfering and calls the ->launder_folio()
address_space op to flush it.  This has problems: firstly, each folio is
written individually as one or more small writes; secondly, adjacent folios
cannot be added so easily into the laundry; thirdly, it's yet another op to
implement.

Instead, use the invalidate lock to cause anyone wanting to add a folio to
the inode to wait, then unmap all the folios if we have mmaps, then,
conditionally, use ->writepages() to flush any dirty data back and then
discard all pages.

The invalidate lock prevents ->read_iter(), ->write_iter() and faulting
through mmap all from adding pages for the duration.

This is then used from netfslib to handle the flusing in unbuffered and
direct writes.

2ff1e97587 netfs: Replace PG_fscache by setting folio->private and marking dirty
When dirty data is being written to the cache, setting/waiting on/clearing
the fscache flag is always done in tandem with setting/waiting on/clearing
the writeback flag.  The netfslib buffered write routines wait on and set
both flags and the write request cleanup clears both flags, so the fscache
flag is almost superfluous.

The reason it isn't superfluous is because the fscache flag is also used to
indicate that data just read from the server is being written to the cache.
The flag is used to prevent a race involving overlapping direct-I/O writes
to the cache.

Change this to indicate that a page is in need of being copied to the cache
by placing a magic value in folio->private and marking the folios dirty.
Then when the writeback code sees a folio marked in this way, it only
writes it to the cache and not to the server.

If a folio that has this magic value set is modified, the value is just
replaced and the folio will then be uplodaded too.

With this, PG_fscache is no longer required by the netfslib core, 9p and
afs.

Ceph and nfs, however, still need to use the old PG_fscache-based tracking.
To deal with this, a flag, NETFS_ICTX_USE_PGPRIV2, now has to be set on the
flags in the netfs_inode struct for those filesystems.  This reenables the
use of PG_fscache in that inode.  9p and afs use the netfslib write helpers
so get switched over; cifs, for the moment, does page-by-page manual access
to the cache, so doesn't use PG_fscache and is unaffected.

257bf89d84 sched/isolation: Fix boot crash when maxcpus < first housekeeping CPU
housekeeping_setup() checks cpumask_intersects(present, online) to ensure
that the kernel will have at least one housekeeping CPU after smp_init(),
but this doesn't work if the maxcpus= kernel parameter limits the number of
processors available after bootup.

For example, a kernel with "maxcpus=2 nohz_full=0-2" parameters crashes at
boot time on a virtual machine with 4 CPUs.

Change housekeeping_setup() to use cpumask_first_and() and check that the
returned CPU number is valid and less than setup_max_cpus.

Another corner case is "nohz_full=0" on a machine with a single CPU or with
the maxcpus=1 kernel argument. In this case non_housekeeping_mask is empty
and tick_nohz_full_setup() makes no sense. And indeed, the kernel hits the
WARN_ON(tick_nohz_full_running) in tick_sched_do_timer().

And how should the kernel interpret the "nohz_full=" parameter? It should
be silently ignored, but currently cpulist_parse() happily returns the
empty cpumask and this leads to the same problem.

Change housekeeping_setup() to check cpumask_empty(non_housekeeping_mask)
and do nothing in this case.

5097cbcb38 sched/isolation: Prevent boot crash when the boot CPU is nohz_full
Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not
include the boot CPU, which is no longer true after:

  08ae95f4fd ("nohz_full: Allow the boot CPU to be nohz_full").

However after:

  aae17ebb53 ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")

the kernel will crash at boot time in this case; housekeeping_any_cpu()
returns an invalid CPU number until smp_init() brings the first
housekeeping CPU up.

Change housekeeping_any_cpu() to check the result of cpumask_any_and() and
return smp_processor_id() in this case.

This is just the simple and backportable workaround which fixes the
symptom, but smp_processor_id() at boot time should be safe at least for
type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu
logic.

There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to
offline tick_do_timer_cpu (the 1st online housekeeping CPU).

57865f3970 RISC-V Fixes for 6.9-rc6
* A fix for TASK_SIZE on rv64/NOMMU, to reflect the lack of user/kernel
   separation.
 * A fix to avoid loading rv64/NOMMU kernel past the start of RAM.
 * A fix for RISCV_HWPROBE_EXT_ZVFHMIN on ilp32 to avoid signed integer
   overflow in the bitmask.
 * The sud_test kselftest has been fixed to properly swizzle the syscall
   number into the return register, which are not the same on RISC-V.
 * A fix for a build warning in the perf tools on rv32.
 * A fix for the CBO selftests, to avoid non-constants leaking into the
   inline asm.
 * A pair of fixes for T-Head PBMT errata probing, which has been renamed
   MAE by the vendor.

5eb4573ea6 ARM SoC fixes for 6.9, part 2
There are a lot of minor DT fixes for Mediatek, Rockchip, Qualcomm and
 Microchip and NXP, addressing both build-time warnings and bugs found during
 runtime testing. Most of these changes are machine specific fixups, but
 there are a few notable regressions that affect an entire SoC:
 
  - The Qualcomm MSI support that was improved for 6.9 ended up being
    wrong on some chips and now gets fixed.
 
  - The i.MX8MP camera interface broke due to a typo and gets
    updated again.
 
 The main driver fix is also for Qualcomm platofrms, rewriting an interface
 in the QSEECOM firmware support that could lead to crashing the kernel
 from a trusted application. The only other code changes are minor fixes
 for Mediatek SoC drivers.

 "There are a lot of minor DT fixes for Mediatek, Rockchip, Qualcomm and
  Microchip and NXP, addressing both build-time warnings and bugs found
  during runtime testing.

  Most of these changes are machine specific fixups, but there are a few
  notable regressions that affect an entire SoC:

   - The Qualcomm MSI support that was improved for 6.9 ended up being
     wrong on some chips and now gets fixed.

   - The i.MX8MP camera interface broke due to a typo and gets updated
     again.

  The main driver fix is also for Qualcomm platforms, rewriting an
  interface in the QSEECOM firmware support that could lead to crashing
  the kernel from a trusted application.

  The only other code changes are minor fixes for Mediatek SoC drivers"

 to situations that we currently cannot handle, so better prevent this

 In the raw NAND subsystem, two runtime fixes have been shared, one
 fixing two important commands in the Qcom driver since it got reworked
 and a NULL pointer dereference happening on STB chips.

Pull vfs fixes from Christian Brauner:
 "This contains a few small fixes for this merge window and the attempt
  to handle the ntfs removal regression that was reported a little while
  ago:

   - After the removal of the legacy ntfs driver we received reports
     about regressions for some people that do mount "ntfs" explicitly
     and expect the driver to be available. Since ntfs3 is a drop-in for
     legacy ntfs we alias legacy ntfs to ntfs3 just like ext3 is aliased
     to ext4.

     We also enforce legacy ntfs is always mounted read-only and give it
     custom file operations to ensure that ioctl()'s can't be abused to
     perform write operations.

   - Fix an unbalanced module_get() in bdev_open().

   - Two smaller fixes for the netfs work done earlier in this cycle.

   - Fix the errno returned from the new FS_IOC_GETUUID and
     FS_IOC_GETFSSYSFSPATH ioctls. Both commands just pull information
     out of the superblock so there's no need to call into the actual
     ioctl handlers.

     So instead of returning ENOIOCTLCMD to indicate to fallback we just
     return ENOTTY directly avoiding that indirection"

 "This is just an update to my maintainer entries as I will switch jobs
  soon. Getting a contact email address into the MAINTAINERS file that

Merge patch series "RISC-V: Test th.sxstatus.MAEE bit before enabling MAEE"
Christoph Müllner <christoph.muellner@vrull.eu> says:

Currently, the Linux kernel suffers from a boot regression when running
on the c906 QEMU emulation. Details have been reported here by Björn Töpel:
  https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg04766.html

The main issue is, that Linux enables XTheadMae for CPUs that have a T-Head
mvendorid but QEMU maintainers don't want to emulate a CPU that uses
reserved bits in PTEs. See also the following discussion for more
context:
  https://lists.gnu.org/archive/html/qemu-devel/2024-02/msg00775.html

This series renames "T-Head PBMT" to "MAE"/"XTheadMae" and only enables
it if the th.sxstatus.MAEE bit is set.

The th.sxstatus CSR is documented here:
  https://github.com/T-head-Semi/thead-extension-spec/blob/master/xtheadsxstatus.adoc

XTheadMae is documented here:
  https://github.com/T-head-Semi/thead-extension-spec/blob/master/xtheadmae.adoc

The QEMU patch to emulate th.sxstatus with the MAEE bit not set is here:
  https://lore.kernel.org/all/20240329120427.684677-1-christoph.muellner@vrull.eu/

After applying the referenced QEMU patch, this patchset allows to
successfully boot a C906 QEMU system emulation ("-cpu thead-c906").

RISC-V: selftests: cbo: Ensure asm operands match constraints, take 2
Commit 0de65288d7 ("RISC-V: selftests: cbo: Ensure asm operands
match constraints") attempted to ensure MK_CBO() would always
provide to a compile-time constant when given a constant, but
cpu_to_le32() isn't necessarily going to do that. Switch to manually
shifting the bytes, when needed, to finally get this right.

AT91 fixes for 6.9

It contains:
- fixes for regulator nodes on SAMA7G5 based boards: proper DT property is used
  to setup regulators suspend voltage.

14e9d449e9 Qualcomm Arm64 DeviceTree fixes for v6.9
This corrects the watchdog IRQ flags for a number of remoteproc
 instances, which otherwise prevents the driver from probe in the face of
 a probe deferral.
 
 Improvements in other areas, such as USB, have made it possible for CX
 rail voltage on SC8280XP to be lowered, no longer meeting requirements
 of active PCIe controllers. Necessary votes are added to these
 controllers.
 
 The MSI definitions for PCIe controllers in SM8450, SM8550, and SM8650
 was incorrect, due to a bug in the driver. As this has now been fixed
 the definition needs to be corrected.
 
 Lastly, the SuperSpeed PHY irq of the second USB controller in SC8180x,
 and the compatible string for X1 Elite domain idle states are corrected.
