Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next

Pull x86 EFI updates from Peter Anvin:
 "A collection of EFI changes.  The perhaps most important one is to
  fully save and restore the FPU state around each invocation of EFI
  runtime, and to not choke on non-ASCII characters in the boot stub"

* 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  efivars: Add compatibility code for compat tasks
  efivars: Refactor sanity checking code into separate function
  efivars: Stop passing a struct argument to efivar_validate()
  efivars: Check size of user object
  efivars: Use local variables instead of a pointer dereference
  x86/efi: Save and restore FPU context around efi_calls (i386)
  x86/efi: Save and restore FPU context around efi_calls (x86_64)
  x86/efi: Implement a __efi_call_virt macro
  x86, fpu: Extend the use of static_cpu_has_safe
  x86/efi: Delete most of the efi_call* macros
  efi: x86: Handle arbitrary Unicode characters
  efi: Add get_dram_base() helper function
  efi: Add shared printk wrapper for consistent prefixing
  efi: create memory map iteration helper
