The following commit has been merged into the x86/asm branch of tip: Commit-ID: b4edca150106a68d05eaf823d665a355ff19e28b Gitweb: https://git.kernel.org/tip/b4edca150106a68d05eaf823d665a355ff19e28b Author: Jiri Slaby <jslaby@xxxxxxx> AuthorDate: Fri, 11 Oct 2019 13:50:59 +02:00 Committer: Borislav Petkov <bp@xxxxxxx> CommitterDate: Fri, 18 Oct 2019 11:29:50 +02:00 x86/asm: Remove the last GLOBAL user and remove the macro Convert the remaining 32bit users and remove the GLOBAL macro finally. In particular, this means to use SYM_ENTRY for the singlestepping hack region. Exclude the global definition of GLOBAL from x86 too.
