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"
* 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/apic: Switch all APICs to Fixed delivery mode
x86/apic: Update the 'apic=' description of setting APIC driver
x86/apic: Avoid wrong warning when parsing 'apic=' in X86-32 case
x86-32: Fix kexec with stack canary (CONFIG_CC_STACKPROTECTOR)
x86: Remove unused parameter of prepare_switch_to
x86/stacktrace: Make zombie stack traces reliable
x86/mm: Unbreak modules that use the DMA API
x86/build: Make isoimage work on Debian
x86/espfix/64: Fix espfix double-fault handling on 5-level systems
