[llvmlinux] [PATCH] [RFC] [X86] Fix a compilation issue with clang.

[dl9pf at gmx.de]

These to patches fix a compilation issues with clang.

[PATCH 1/2] Extend definitions of __ASM_* with a raw format.

Extends the helper macros __ASM_*  (e.g. __ASM_DX) with a format that 
does not add whitespace. Both gcc and clang choke in that case.

[PATCH 2/2] [X86] Fix a compilation issue with clang.

This is the actual issue here. In the 64bit case, clang just sees
edx (a 32bit register name) and does not use more than 32bit.
As pointed out in the comment in uaccess.h, gcc is happy with edx as the
starting point (and does not care about the size).
This fix pleases both worlds as we just use edx on 32 and rdx on 64.

Please apply.
