Linus Torvalds a358505d8a Peter Zijlstra says:
These patches address a number of instrumentation issues that were found after
 the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these
 patches make UBSAN/KASAN/KCSAN happy again.
 
 Part of making this all work is bumping the minimum GCC version for KASAN
 builds to gcc-8.3, the reason for this is that the __no_sanitize_address
 function attribute is broken in GCC releases before that.
 
 No known GCC version has a working __no_sanitize_undefined, however because the
 only noinstr violation that results from this happens when an UB is found, we
 treat it like WARN. That is, we allow it to violate the noinstr rules in order
 to get the warning out.

Merge tag 'x86_entry_for_5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 entry fixes from Borislav Petkov:
 "This is the x86/entry urgent pile which has accumulated since the
  merge window.

  It is not the smallest but considering the almost complete entry core
  rewrite, the amount of fixes to follow is somewhat higher than usual,
  which is to be expected.
