Subject[PATCH v2] arm: export "W" macro just for assembly code
From: Alexey Dobriyan <>

The W macro which got introduced in 0becb08 aka "Thumb-2: Add macros for
the unified assembler syntax" clashes with the W function in
crypto/cast6.c since commit 8b59278 aka "Thumb-2: Implement the unified
arch/arm/lib functions" due to the following include path:
|arch/arm/include/asm/unified.h <---

This patch allows the usage of the new W macro only in assembly files
since it is the place where it is used.

Russel, I've added a new patch description for this patch since my
rename edition was a little larger.
