Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A couple of fixlets for x86:
- Fix the ESPFIX double fault handling for 5-level pagetables
- Fix the commandline parsing for 'apic=' on 32bit systems and update
documentation
- Make zombie stack traces reliable
- Fix kexec with stack canary
- Fix the delivery mode for APICs which was missed when the x86
vector management was converted to single target delivery. Caused a
regression due to the broken hardware which ignores affinity
settings in lowest prio delivery mode.
- Unbreak modules when AMD memory encryption is enabled
- Remove an unused parameter of prepare_switch_to"
