 "Fixes:

   - When we added basic vDSO support in kernel 5.18 we introduced a bug
     which prevented a mmap() of graphic card memory. This is because we
     used the DMB (data memory break trap bit) page flag as special-bit,
     but missed to clear that bit when loading the TLB.

   - Graphics card memory size was not correctly aligned

   - Spelling fixes (from Colin Ian King)

  Enhancements:

   - PDC console (which uses firmware calls) now rewritten as early
     console

   - Reduced size of alternative tables"

      drm/amd/display: Fix build breakage with CONFIG_DEBUG_FS=n · 2130b87b
      Nathan Chancellor authored 
      After commit 8799c0be ("drm/amd/display: Fix vblank refcount in vrr
transition"), a build with CONFIG_DEBUG_FS=n is broken due to a
misplaced brace, along the lines of:

  In file included from drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_trace.h:39,
                   from drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:41:

Move the brace within the #ifdef so that the file can be built with or
without CONFIG_DEBUG_FS.

      parisc: Fix userspace graphics card breakage due to pgtable special bit · 70be49f2
      Helge Deller authored 
      Commit df24e178 ("parisc: Add vDSO support") introduced the vDSO
support, for which a _PAGE_SPECIAL page table flag was needed.  Since we
wanted to keep every page table entry in 32-bits, this patch re-used the
existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break
if a page is accessed) to store the special bit.

But when graphics card memory is mmapped into userspace, the kernel uses
vm_iomap_memory() which sets the the special flag. So, with the DMB bit
set, every access to the graphics memory now triggered a hardware
exception and segfaulted the userspace program.

Fix this breakage by dropping the DMB bit when writing the page
protection bits to the CPU TLB.

In addition this patch adds a small optimization: if huge pages aren't
configured (which is at least the case for 32-bit kernels), then the
special bit is stored in the hpage (HUGE PAGE) bit instead. That way we
can skip to reset the DMB bit.

      Independend of the current graphics resolution, adjust the reported
graphics card memory size to the next 4MB boundary.
This fixes the fbtest program which expects a naturally aligned size.
