Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin:
"A collection of minor fixes, more EFI variables paranoia
(anti-bricking) plus the ability to disable the pstore either as a
runtime default or completely, due to bricking concerns."
* 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efivars: Fix check for CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE
x86, microcode_intel_early: Mark apply_microcode_early() as cpuinit
efivars: Handle duplicate names from get_next_variable()
efivars: explicitly calculate length of VariableName
efivars: Add module parameter to disable use as a pstore backend
efivars: Allow disabling use as a pstore backend
x86-32, microcode_intel_early: Fix crash with CONFIG_DEBUG_VIRTUAL
x86-64: Fix the failure case in copy_user_handle_tail()
