Subject[PATCH v3 1/5] ARM: use unified assembler in macros
Date
Use unified assembler syntax (UAL) in macros. Divided syntax is
considered deprecated. This will also allow to build the kernel
using LLVM's integrated assembler.

Acked-by: Nicolas Pitre <nico@linaro.org>

Changes in v2:
- Remove excessive null tokens
