396ea16818 ceph: remove incorrect session state check
Once the session is opened the s->s_ttl will be set, and when receiving
a new mdsmap and the MDS map is changed, it will be possibly will close
some sessions and open new ones. And then some sessions will be in
CLOSING state evening without unmounting.

7f47f7f3b3 ceph: get snap_rwsem read lock in handle_cap_export for ceph_add_cap
ceph_add_cap says in its function documentation that the caller should
hold the read lock on the session snap_rwsem. Furthermore, not only
ceph_add_cap needs that lock, when it calls to ceph_lookup_snap_realm it
eventually calls ceph_get_snap_realm which states via lockdep that
snap_rwsem needs to be held. handle_cap_export calls ceph_add_cap
without that mdsc->snap_rwsem held. Thus, since ceph_get_snap_realm
and ceph_add_cap both need the lock, the common place to acquire that
lock is inside handle_cap_export.

c05d8332f5 drm/i915: Check EDID for HDR static metadata when choosing blc
We have now seen panel (XMG Core 15 e21 laptop) advertizing support
for Intel proprietary eDP backlight control via DPCD registers, but
actually working only with legacy pwm control.

This patch adds panel EDID check for possible HDR static metadata and
Intel proprietary eDP backlight control is used only if that exists.
Missing HDR static metadata is ignored if user specifically asks for
Intel proprietary eDP backlight control via enable_dpcd_backlight
parameter.

v2 :
- Ignore missing HDR static metadata if Intel proprietary eDP
  backlight control is forced via i915.enable_dpcd_backlight
- Printout info message if panel is missing HDR static metadata and
  support for Intel proprietary eDP backlight control is detected

Fixes: 4a8d79901d ("drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now)")

ed911c9f9d drm/i915: Fix DISP_POS_Y and DISP_HEIGHT defines
Commit 428cb15d5b ("drm/i915: Clean up pre-skl primary plane registers")
introduced DISP_POS_Y and DISP_HEIGHT defines but accidentally set these
their masks to REG_GENMASK(31, 0) instead of REG_GENMASK(31, 16).

This breaks the primary display pane on at least pineview machines, fix
the mask to fix the primary display pane only showing black.

Tested on an Acer One AO532h with an Intel N450 SoC.

All users of this function require width-mm/height-mm DT property to be
present per their DT bindings, make width-mm/height-mm check mandatory.
It is generally a good idea to specify panel dimensions, so userspace
can configure e.g. scaling accordingly.

b4f3d5f06e clk: sunxi-ng: sun6i-rtc: Mark rtc-32k as critical
Because some newer hardware variants have multiple possible parents for
the RTC's timekeeping clock, this driver models it as a "rtc-32k" clock.
However, it does not add any consumer for this clock. This causes the
common clock framework to disable it, preventing RTC time access.

Since the RTC's timekeeping clock should always be enabled, regardless
of which drivers are loaded, let's mark this clock as critical instead
of adding a consumer in the RTC driver.

9becb68891 kvmalloc: use vmalloc_huge for vmalloc allocations
Since commit 559089e0a9 ("vmalloc: replace VM_NO_HUGE_VMAP with
VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc is an
opt-in strategy, because it caused a number of problems that weren't
noticed until x86 enabled it too.

One of the issues was fixed by Nick Piggin in commit 3b8000ae18
("mm/vmalloc: huge vmalloc backing pages should be split rather than
compound"), but I'm still worried about page protection issues, and
VM_FLUSH_RESET_PERMS in particular.

However, like the hash table allocation case (commit f2edd118d0:
"page_alloc: use vmalloc_huge for large system hash"), the use of
kvmalloc() should be safe from any such games, since the returned
pointer might be a SLUB allocation, and as such no user should
reasonably be using it in any odd ways.

We also know that the allocations are fairly large, since it falls back
to the vmalloc case only when a kmalloc() fails.  So using a hugepage
mapping seems both safe and relevant.

This patch does show a weakness in the opt-in strategy: since the opt-in
flag is in the 'vm_flags', not the usual gfp_t allocation flags, very
few of the usual interfaces actually expose it.

That's not much of an issue in this case that already used one of the
fairly specialized low-level vmalloc interfaces for the allocation, but
for a lot of other vmalloc() users that might want to opt in, it's going
to be very inconvenient.

We'll either have to fix any compatibility problems, or expose it in the
gfp flags (__GFP_COMP would have made a lot of sense) to allow normal
vmalloc() users to use hugepage mappings.  That said, the cases that
really matter were probably already taken care of by the hash tabel
allocation.

f2edd118d0 page_alloc: use vmalloc_huge for large system hash
Use vmalloc_huge() in alloc_large_system_hash() so that large system
hash (>= PMD_SIZE) could benefit from huge pages.

Note that vmalloc_huge only allocates huge pages for systems with
HAVE_ARCH_HUGE_VMALLOC.

This is due to the AT25 driver using buffers on stack, which is not
possible with CONFIG_VMAP_STACK.

As mentionned in kernel Documentation (Documentation/spi/spi-summary.rst):

  - Follow standard kernel rules, and provide DMA-safe buffers in
    your messages.  That way controller drivers using DMA aren't forced
    to make extra copies unless the hardware requires it (e.g. working
    around hardware errata that force the use of bounce buffering).

Modify the driver to use a buffer located in the at25 device structure
which is allocated via kmalloc during probe.

Protect writes in this new buffer with the driver's mutex.

  send Incoming SSN Reset Request --->
  CPU0:
   reconf timer is triggered,
   go to the handler code before hold sk lock
                            <--- reply with Outgoing SSN Reset Request

   process Outgoing SSN Reset Request,
   and set asoc->strreset_chunk to NULL
  CPU0:
   continue the handler code, hold sk lock,
   and try to hold asoc->strreset_chunk, crash!

In Ying Xu's testing, the call trace is:

  [ ] BUG: kernel NULL pointer dereference, address: 0000000000000010

544ccad739 drm/vmwgfx: Reserve fence slots on buffer objects in cotables
The buffer objects created by cotables were missing fence reservations.
They are created from vmw_validation_res_validate which makes them miss
the ttm_eu_reserve_buffers which is called from vmw_validation_bo_reserve.

Cotables are the only resources which create a buffer object in the
create callback so make sure the code also reserves the slots.

6deb9bf458 riscv: dts: microchip: reparent mpfs clocks
The 600M clock in the fabric is not the real reference, replace it with
a 125M clock which is the correct value for the icicle kit. Rename the
msspllclk node to mssrefclk since this is now the input to, not the
output of, the msspll clock. Control of the msspll clock has been moved
into the clock configurator, so add the register range for it to the clk
configurator. Finally, add a new output of the clock config block which
will provide the 1M reference clock for the MTIMER and the rtc.

445c2da897 clk: microchip: mpfs: re-parent the configurable clocks
Currently the mpfs clock driver uses a reference clock called the
"msspll", set in the device tree, as the parent for the cpu/axi/ahb
(config) clocks. The frequency of the msspll is determined by the FPGA
bitstream & the bootloader configures the clock to match the bitstream.
The real reference is provided by a 100 or 125 MHz off chip oscillator.

However, the msspll clock is not actually the parent of all clocks on
the system - the reference clock for the rtc/mtimer actually has the
off chip oscillator as its parent.

In order to fix this, add support for reading the configuration of the
msspll & reparent the "config" clocks so that they are derived from
this clock rather than the reference in the device tree.

The fic clocks passed to the pcie controller and other peripherals in
the device tree are not the clocks they actually run on. The fics are
actually clock domain crossers & the clock config blocks output is the
mss/cpu side input to the interconnect. The peripherals are actually
clocked by fixed frequency clocks embedded in the fpga fabric.

Fix the device tree so that these peripherals use the correct clocks.
The fabric side FIC0 & FIC1 inputs both use the same 125 MHz, so only
one clock is created for them.
