Various Kconfig options selected the per-architecture helpers for
fbdev. But none of the contained code depends on fbdev. Standardize
on CONFIG_VIDEO, which will allow to add more general helpers for
video functionality.

CONFIG_VIDEO protects each architecture's video/ directory. This
allows for the use of more fine-grained control for each directory's
files, such as the use of CONFIG_STI_CORE on parisc.

Change the return types of bitops functions (ffs, fls, and fns) from
long to int. The expected return values are in the range [0, 64], for
which int is sufficient.

Additionally, int aligns well with the return types of the corresponding
__builtin_* functions, potentially reducing overall type conversions.

Many of the existing bitops functions already return an int and don't
need to be changed. The bitops functions in arch/ should be considered
separately.

Adjust some return variables to match the function return types.

With GCC 13 and defconfig, these changes reduced the size of a test
kernel image by 5,432 bytes on arm64 and by 248 bytes on riscv; there
were no changes in size on x86_64, powerpc, or m68k.

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.

Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not
include the boot CPU, which is no longer true after:

  08ae95f4 ("nohz_full: Allow the boot CPU to be nohz_full").

However after:

  aae17ebb ("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).

     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

MediaTek driver fixes for v6.9

This fixes the MediaTek SVS driver to look for the right thermal zone
names, and adds a missing Kconfig dependency for mtk-socinfo.

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").

Commit 0de65288 ("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.

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.

In netfs_perform_write(), when the file is marked NETFS_ICTX_WRITETHROUGH
or O_*SYNC or RWF_*SYNC was specified, write-through caching is performed
on a buffered file.  When setting up for write-through, we flush any
conflicting writes in the region and wait for the write to complete,
failing if there's a write error to return.

The issue arises if we're writing at or above the EOF position because we
skip the flush and - more importantly - the wait.  This becomes a problem
if there's a partial folio at the end of the file that is being written out
and we want to make a write to it too.  Both the already-running write and
the write we start both want to clear the writeback mark, but whoever is
second causes a warning looking something like:

    ------------[ cut here ]------------
    R=00000012: folio 11 is not under writeback
    WARNING: CPU: 34 PID: 654 at fs/netfs/write_collect.c:105
    ...
    CPU: 34 PID: 654 Comm: kworker/u386:27 Tainted: G S ...
    ...
    Workqueue: events_unbound netfs_write_collection_worker
    ...
    RIP: 0010:netfs_writeback_lookup_folio

Fix this by making the flush-and-wait unconditional.  It will do nothing if
there are no folios in the pagecache and will return quickly if there are
no folios in the region specified.

Further, move the WBC attachment above the flush call as the flush is going
to attach a WBC and detach it again if it is not present - and since we
need one anyway we might as well share it.
