drm/bochs: use devm_ioremap_wc() to map framebuffer

Opt for devm_ioremap_wc() over devm_ioremap() when mapping the framebuffer.

Using devm_ioremap() results in the VA being mapped with PAT=UC-, which
considerably slows down drm_fb_memcpy(). In contrast, devm_ioremap_wc()
maps the VA with PAT set to WC, leading to better performance on platforms
where access to UC memory is much slower than WC memory.

Here's the performance data measured in a guest on the physical machine
"Sapphire Rapids XCC".
With host KVM honors guest PAT memory types, the effective memory type
for this framebuffer range is
- WC when devm_ioremap_wc() is used
- UC- when devm_ioremap() is used.

The data presented is an average from 10 execution runs.

Cycles: Avg cycles of executed bochs_primary_plane_helper_atomic_update()
        from VM boot to GDM show up
Cnt:    Avg cnt of executed bochs_primary_plane_helper_atomic_update()
        from VM boot to GDM show up
T:      Avg time of each bochs_primary_plane_helper_atomic_update().

Note:
Following the rebase to [3], the previously reported GDM failure on the

drm/panthor: Display FW version information

The version number output when loading the firmware is actually the
interface version not the version of the firmware itself. Update the
message to make this clearer.

However, the firmware binary has a git SHA embedded into it which can be
used to identify which firmware binary is being loaded. So output this
as a drm_info() so that it's obvious from a dmesg log which firmware
binary is being used.

drm/bridge: ti-sn65dsi86: annotate ti_sn_pwm_pin_{request, release} with __maybe_unused

Building with clang, W=1, CONFIG_PM=n and CONFIG_OF_GPIO=n leads to
warning about unused ti_sn_pwm_pin_request() and
ti_sn_pwm_pin_release(). Fix by annotating them with __maybe_unused.

See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").

Three cleanups
- Drop stale exynos file pattern from MAINTAINERS file
  The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory.

- Constify struct exynos_drm_ipp_funcs
  By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size.

- Remove unnecessary code
  The function exynos_atomic_commit is removed as it became redundant after a previous update. This cleans up the code and eliminates unused function declarations.

One fixup
- Fix wrong assignment in gsc_bind()

drm/vc4: hvs: Change prototype of __vc4_hvs_alloc to pass registers

The BCM2712 HVS has registers to report the size of the various SRAM the
driver uses, and their size actually differ depending on the stepping.

The initialisation of the memory pools happen in the __vc4_hvs_alloc()
function that also allocates the main HVS structure, that will then hold
the pointer to the memory mapping of the registers.

This creates some kind of circular dependency that we can break by
passing the mapping pointer as an argument for __vc4_hvs_alloc() to use
to query to get the SRAM sizes and initialise the memory pools
accordingly.

drm/vc4: hvs: Rework LBM alignment

With the introduction of the support for BCM2712, the check of whether

Moreover, the LBM size will need to be computed in words for the

Aligning on either 64 or 32 words is thus fairly harmful on BCM2712, so

drm/vc4: hvs: Remove ABORT_ON_EMPTY flag

ABORT_ON_EMPTY chooses whether the HVS abandons the current frame
when it experiences an underflow, or attempts to continue.

In theory the frame should be black from the point of underflow,
compared to a shift of sebsequent pixels to the left.

Unfortunately it seems to put the HVS is a bad state where it is not
possible to recover simply. This typically requires a reboot
following the 'flip done timed out message'.

Discussion with Broadcom has suggested we don't use this flag.
All their testing is done with it disabled.

Additionally setting BLANK_INSERT_EN causes the HDMI to output
blank pixels on an underflow which avoids it losing sync.

After this change a 'flip done timed out' due to sdram bandwidth
starvation or too low a clock is recoverable once the situation improves.

Trying to read /sys/kernel/debug/dri/1/hdmi1_regs

   - Parking shared RCGs at a slow always on clk at registration time

KVM: x86: don't fall through case statements without annotations

clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.

   userspace workloads.

 - A fix to avoid a kernel memory leak when emulating misaligned
   accesses from userspace.

 - A Kconfig fix for toolchain vector detection, which now correctly
   detects vector support on toolchains where the V extension depends on
   the M extension.

 - A fix to avoid failing the linear mapping bootmem bounds check on
