[PATCH 0/2] Allow assembly code to use BIT(), GENMASK(), etc. and clean-up arm64 header

[Masahiro Yamada]

Some in-kernel headers use _BITUL() instead of BIT().

 arch/arm64/include/asm/sysreg.h
 arch/s390/include/asm/*.h

I think the reason is because BIT() is currently not available
in assembly. It hard-codes 1UL, which is not available in assembly.

1/2 replaced
   1UL -> UL(1)
   0UL -> UL(0)
   1ULL -> ULL(1)
   0ULL -> ULL(0)

With this, there is no more restriction that prevents assembly
code from using them.

2/2 is a clean-up as as example.

I can contribute to cleanups of arch/s390/, etc.
once this series lands in upstream.

I hope both patches can go in the arm64 tree.

  linux/bits.h: make BIT(), GENMASK(), and friends available in assembly
  arm64: replace _BITUL() with BIT()
