      Pull RISC-V updates from Palmer Dabbelt:
      
       - Support for the Svpbmt extension, which allows memory attributes to
         be encoded in pages
      
       - Support for the Allwinner D1's implementation of page-based memory
         attributes
      
       - Support for running rv32 binaries on rv64 systems, via the compat
         subsystem
      
       - Support for kexec_file()
      
       - Support for the new generic ticket-based spinlocks, which allows us
         to also move to qrwlock. These should have already gone in through
         the asm-geneic tree as well
      
       - A handful of cleanups and fixes, include some larger ones around
         atomics and XIP

      RISC-V: Prepare dropping week attribute from arch_kexec_apply_relocations[_add] · 7699f7aa
      Uwe Kleine-König authored
      Without this change arch/riscv/kernel/elf_kexec.c fails to compile once
      commit 233c1e6c319c ("kexec_file: drop weak attribute from
      arch_kexec_apply_relocations[_add]") is also contained in the tree.
      This currently happens in next-20220527.
      
      Prepare the RISC-V similar to the s390 adaption done in 233c1e6c319c.
      This is safe to do on top of the riscv change even without the change to
      arch_kexec_apply_relocations.

      The symbol hwa742_update_window_async() is exported, but there is no
      prototype defined for it. That's why gcc complains:
      
      drivers-video-fbdev-omap-hwa742.c:warning:no-previous-prototype-for-hwa742_update_window_async
      
      Add the prototype, but I wonder if we couldn't drop exporting the symbol
      instead. Since omapfb_update_window_async() is exported the same way,
      are there any users outside of the tree?

      drm: fix EDID struct for old ARM OABI format · 47f15561
      Linus Torvalds authored
      When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
      will force alignment of all structures and unions to a word boundary
      (see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
      option if you're a gcc person), even when the members of said structures
      do not want or need said alignment.
      
      This completely messes up the structure alignment of 'struct edid' on
      those targets, because even though all the embedded structures are
      marked with "__attribute__((packed))", the unions that contain them are
      not.
      
      This was exposed by commit f1e4c916 ("drm/edid: add EDID block count
      and size helpers"), but the bug is pre-existing.  That commit just made
      the structure layout problem cause a build failure due to the addition
      of the
      
              BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH);
      
      sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data().
      
      This legacy union alignment should probably not be used in the first
      place, but we can fix the layout by adding the packed attribute to the
      union entries even when each member is already packed and it shouldn't
      matter in a sane build environment.
      
      You can see this issue with a trivial test program:
      
        union {
      	struct {
      		char c[5];
      	};
      	struct {
      		char d;
      		unsigned e;
      	} __attribute__((packed));
        } a = { "1234" };
      
      where building this with a normal "gcc -S" will result in the expected
      5-byte size of said union:
      
      	.type	a, @object
      	.size	a, 5
      
      but with an ARM compiler and the old ABI:
      
          arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c
      
      you get
      
      	.type	a, %object
      	.size	a, 8
      
      instead, because even though each member of the union is packed, the
      union itself still gets aligned.
      
      This was reported by Sudip for the spear3xx_defconfig target.
