Subject: [kvm-unit-tests PATCH v2 0/4] Fix arm64 clang errors on fpu tests

When compiled with clang for arm64, some build errors were observed
along the fpu code. Moreover, data aborts were seen while running
the arm/fpu test due to misconfigured input/output args in the inline
assembly.

The series tries to address these issues.

v2:
 - Fix build errors for newer clang versions that push 'q' registers out
   of scope under '-mgeneral-regs-only'. (Andrew)

v1:

- Raghavendra

Raghavendra Rao Ananta (4):
  arm: Fix clang error in sve_vl()
  arm: fpu: Convert 'q' registers to 'v' to satisfy clang
  arm: fpu: Add '.arch_extension fp' to fpu macros
  arm: fpu: Fix the input/output args for inline asm in fpu.c
