Merge branch 'x86/bugs' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Cross merge x86 fixes to fix clang linking errors:

ld.lld: error: ./arch/x86/kernel/vmlinux.lds:221: at least one side of the expression must be absolute

These will hopefully be downstream by the time we ship
the next batch of fixes.
