  efi/bgrt: Skip efi_bgrt_init in case of non-efi boot (2017-05-26 11:27:38 +0100)

----------------------------------------------------------------
 - Make the boot console quiet when using Xen on EFI by deleting a
   pointless error message - Juergen Gross

 - Silence harmless warnings emitted with GCC 7 - Arnd Bergmann

 - Prevent a crash when booting kexec with the efi=old_map kernel
   command line parameter by disabling EFI runtime services - Sai Praneeth

 - Fix boot crash when using kaslr and efi=old_map. The crash is
   caused because of assumptions about PAGE_OFFSET alignment which are
   not true with kaslr enabled - Baoquan He

 - Fix boot regression when a machine has an ACPI BGRT table and is
   booted using BIOS, not EFI.  - Dave Young

----------------------------------------------------------------
Arnd Bergmann (1):
      efi: Remove duplicate 'const' specifiers

Baoquan He (1):
      x86/efi: Correct ident mapping of efi old_map when kalsr enabled

Dave Young (1):
      efi/bgrt: Skip efi_bgrt_init in case of non-efi boot

Juergen Gross (1):
      efi: Don't issue error message when booted under xen

Sai Praneeth (1):
      x86/efi: Disable runtime services on kexec kernel if booted with efi=old_map
