Subject: [PATCH stable 5.4 00/11] ARM 32-bit build with Clang IAS

Hi,

This patch series is a collection of clean cherry picks into the 5.4
kernel allowing us to use the Clang integrated assembler to build the
ARM 32-bit kernel.

This is useful in order to have proper build and runtime coverage of the
stable kernel(s).

Ard Biesheuvel (3):
  crypto: arm/sha256-neon - avoid ADRL pseudo instruction
  crypto: arm/sha512-neon - avoid ADRL pseudo instruction
  crypto: arm - use Kconfig based compiler checks for crypto opcodes

Jian Cai (2):
  ARM: 8971/1: replace the sole use of a symbol with its definition
  ARM: 9029/1: Make iwmmxt.S support Clang's integrated assembler

Nick Desaulniers (1):
  ARM: 8933/1: replace Sun/Solaris style flag on section directive

Stefan Agner (5):
  ARM: 8989/1: use .fpu assembler directives instead of assembler
    arguments
  ARM: 8990/1: use VFP assembler mnemonics in register load/store macros
  ARM: 8929/1: use APSR_nzcv instead of r15 as mrc operand
  ARM: OMAP2+: drop unnecessary adrl
  crypto: arm/ghash-ce - define fpu before fpu registers are referenced
