Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from H. Peter Anvin.
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x32, siginfo: Provide proper overrides for x32 siginfo_t
asm-generic: Allow overriding clock_t and add attributes to siginfo_t
x32: Check __ILP32__ instead of __LP64__ for x32
x86, acpi: Call acpi_enter_sleep_state via an asmlinkage C function from assembler
ACPI: Convert wake_sleep_flags to a value instead of function
x86, apic: APIC code touches invalid MSR on P5 class machines
i387: ptrace breaks the lazy-fpu-restore logic
x86/platform: Remove incorrect error message in x86_default_fixup_cpu_id()
x86, efi: Add dedicated EFI stub entry point
x86/amd: Remove broken links from comment and kernel message
x86, microcode: Ensure that module is only loaded on supported AMD CPUs
x86, microcode: Fix sysfs warning during module unload on unsupported CPUs
