[GIT PULL] EFI changes for v3.20 (resend)

[GIT PULL] EFI changes for v3.20 (resend)

[Matt Fleming]

Folks, please consider pulling the following changes for v3.20. There's
nothing super scary, mainly cleanups, and a merge from Ricardo who
kindly picked up some patches from the linux-efi mailing list while I
was out on annual leave in December.

Perhaps the biggest risk is the get_memory_map() change from Ard, which
changes the way that both the arm64 and x86 EFI boot stub build the
early memory map. It would be good to have it bake in linux-next for a
while.

One other thing to note is that I've picked up an rtc-efi patch from Ard
because the rtc maintainer hasn't been responsive for a while now.

The following changes since commit 8266e31ed0fedb7ee16ebc86e80468f7cc1bbb4e:

  x86, ptdump: Add section for EFI runtime services (2014-11-11 22:28:57 +0000)

  efi: Don't look for chosen@0 node on DT platforms (2015-01-20 22:41:56 +0000)

----------------------------------------------------------------
 * Move efivarfs from the misc filesystem section to pseudo filesystem,
   since that's a more logical and accurate place - Leif Lindholm

 * Update efibootmgr URL in Kconfig help - Peter Jones

 * Improve accuracy of EFI guid function names - Borislav Petkov

 * Expose firmware platform size in sysfs for the benefit of EFI boot
   loader installers and other utilities - Steve McIntyre

 * Cleanup __init annotations for arm64/efi code - Ard Biesheuvel

 * Mark the UIE as unsupported for rtc-efi - Ard Biesheuvel

 * Fix memory leak in error code path of runtime map code - Dan Carpenter

 * Improve robustness of get_memory_map() by removing assumptions on the
   size of efi_memory_desc_t (which could change in future spec
   versions) and querying the firmware instead of guessing about the
   memmap size - Ard Biesheuvel

 * Remove superfluous guid unparse calls - Ivan Khoronzhuk

 * Delete unnecessary chosen@0 DT node FDT code since was duplicated
   from code in drivers/of and is entirely unnecessary - Leif Lindholm
