Subject: x86/bug: Put HAVE_ARCH_BUG_FORMAT_ARGS WARN definitions inside __ASSEMBLER__
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=23aea3c539a62ab97ca3aecf41d590d91f2911fc;p=thirdparty%2Flinux.git

x86/bug: Put HAVE_ARCH_BUG_FORMAT_ARGS WARN definitions inside __ASSEMBLER__

Extend the !assembly #ifdef guarding x86's custom WARN helpers to cover the
WARN macros themselves, as they aren't assembly friendly.  This helps make
it clear that things like __WARN_validate_printf() don't need a dummy
definition for assembly code.

No functional change intended.
