The following commit has been merged into the x86/asm branch of tip: Commit-ID: 2ce0d7f9766f0e49bb54f149c77bae89464932fb Gitweb: https://git.kernel.org/tip/2ce0d7f9766f0e49bb54f149c77bae89464932fb Author: Mark Brown <broonie@xxxxxxxxxx> AuthorDate: Thu, 16 Apr 2020 19:24:02 +01:00 Committer: Borislav Petkov <bp@xxxxxxx> CommitterDate: Sat, 18 Apr 2020 17:43:09 +02:00 x86/asm: Provide a Kconfig symbol for disabling old assembly annotations As x86 was converted to use the modern SYM_ annotations for assembly, ifdefs were added to remove the generic definitions of the old style annotations on x86. Rather than collect a list of architectures in the ifdefs as more architectures are converted over, provide a Kconfig symbol for this and update x86 to use it.
