Subject: x86, asm: Extend definitions of _ASM_* with a raw format
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=be43426ccfca03659780c1aeef6b953036e5fccf;p=pandora-kernel.git

x86, asm: Extend definitions of _ASM_* with a raw format

commit 3e9b2327b59801e677a7581fe4d2541ca749dcab upstream.

The __ASM_* macros (e.g. __ASM_DX) are used to return the proper
register name (e.g. edx for 32bit / rdx for 64bit). We want to use
this also in arch/x86/include/asm/uaccess.h / get_user() .  For this
to work, we need a raw form as both gcc and clang choke on the
whitespace in a register asm() statement, and the __ASM_FORM macro
surrounds the argument with blanks.  A new macro, __ASM_FORM_RAW was
added and we change __ASM_REG to use the new RAW form.
