Commit e7607f7d6d81 ("ARM: 9443/1: Require linker to support KEEP within
OVERLAY for DCE") accidentally broke the binutils version restriction
that was added in commit 0d437918fb64 ("ARM: 9414/1: Fix build issue
with LD_DEAD_CODE_DATA_ELIMINATION"), reintroducing the segmentation
fault addressed by that workaround.

Restore the binutils version dependency by using
CONFIG_LD_CAN_USE_KEEP_IN_OVERLAY as an additional condition to ensure
that CONFIG_HAVE_LD_DEAD_CODE_DATA_ELIMINATION is only enabled with
binutils &gt;= 2.36 and ld.lld &gt;= 21.0.0.

After commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper
flags and language target"), which updated as-instr to use the
'assembler-with-cpp' language option, the Kbuild version of as-instr
always fails internally for arch/arm with

  &lt;command-line&gt;: fatal error: asm/unified.h: No such file or directory
  compilation terminated.

because '-include' flags are now taken into account by the compiler
driver and as-instr does not have '$(LINUXINCLUDE)', so unified.h is not
found.

This went unnoticed at the time of the Kbuild change because the last
use of as-instr in Kbuild that arch/arm could reach was removed in 5.7
by commit 541ad0150ca4 ("arm: Remove 32bit KVM host support") but a
stable backport of the Kbuild change to before that point exposed this
potential issue if one were to be reintroduced.

Follow the general pattern of '-include' paths throughout the tree and
make unified.h absolute using '$(srctree)' to ensure KBUILD_AFLAGS can
be used independently.

Make pte_swp_exclusive return bool instead of int.  This will better
reflect how pte_swp_exclusive is actually used in the code.

This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not
returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper
32-bits of PTE (like on alpha).

Pull ARM fixes from Russell King:

 - Fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to
   memblock_is_map_memory rather than the actual address.

 - Disallow kernel mode NEON when IRQs are disabled

   Explanation:

     "To avoid having to preserve/restore kernel mode NEON state when
      such a softirq is taken softirqs are now disabled when using the
      NEON from task context."

   should explain that it's nested kernel mode.

   In other words, softirqs from user mode are fine, because the context
   will be preserved. softirqs from kernel mode may be from a context
   that has already saved the user NEON state, and thus we would need to
   preserve the NEON state for the parent kernel mode context, and this
   we don't allow.

   The problem occurs when the kernel context disables hard IRQs, and
   then uses NEON. When it's finished, and restores the userspace NEON
   state, we call local_bh_enable() with hard IRQs disabled, which
   causes a warning.

   This commit addresses that by disallowing the use of NEON with hard
   IRQs disabled.

  ARM: 9446/1: Disallow kernel mode NEON when IRQs are disabled
  ARM: 9447/1: arm/memremap: fix arch_memremap_can_ram_remap()
</content>

Pull ARM fixes from Russell King:

 - Fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to
   memblock_is_map_memory rather than the actual address.

 - Disallow kernel mode NEON when IRQs are disabled

   Explanation:

     "To avoid having to preserve/restore kernel mode NEON state when
      such a softirq is taken softirqs are now disabled when using the
      NEON from task context."

   should explain that it's nested kernel mode.

   In other words, softirqs from user mode are fine, because the context
   will be preserved. softirqs from kernel mode may be from a context
   that has already saved the user NEON state, and thus we would need to
   preserve the NEON state for the parent kernel mode context, and this
   we don't allow.

   The problem occurs when the kernel context disables hard IRQs, and
   then uses NEON. When it's finished, and restores the userspace NEON
   state, we call local_bh_enable() with hard IRQs disabled, which
   causes a warning.

   This commit addresses that by disallowing the use of NEON with hard
   IRQs disabled.
