Please, fold into 0becb088501886f37ade38762c8eaaf4263572cc
aka "Thumb-2: Add macros for the unified assembler syntax"

otherwise:

	crypto/cast6.c:372:39: error: macro "W" passed 2 arguments, but takes just 1

Folding it into that commit is not possible; as such a better patch
description is desirable.

[PATCH v2] arm: export "W" macro just for assembly code

[Sebastian Andrzej Siewior]

From: Alexey Dobriyan <adobriyan@gmail.com>

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 <---
|arch/arm/include/asm/uaccess.h:20
|include/linux/uaccess.h:5
|include/linux/crypto.h:26
|crypto/cast6.c:23

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.

I already added a patch with the modified description in my for-rmk
branch. I'm not sure Russell had time to pull it.

It got pulled before you modified it, so we're going to have to live
with it with its silly description now.
