[GIT PULL] EFI urgent fixes

[Matt Fleming <matt@codeblueprint.co.uk>]

Folks, please pull the following urgent EFI fixes which prevent an oops
if users pass an invalid "efi" kernel parameter and a boot issue seen on
Parallels virtual machines.

The tag is based on v4.2-rc4, let me know if you want me to rebase it on
top of something else.

The following changes since commit cbfe8fa6cd672011c755c3cd85c9ffd4e2d10a6f:

  efi: Check for NULL efi kernel parameters (2015-07-30 18:07:11 +0100)

----------------------------------------------------------------
 * Fix an EFI boot issue preventing a Parallels virtual machine from
   booting because the upper 32-bits of the EFI memmap pointer were
   being discarded in setup_e820() - Dmitry Skorodumov

 * Validate that the "efi" kernel parameter gets used with an argument,
   otherwise we will oops - Ricardo Neri

Dmitry Skorodumov (1):
      x86/efi: Use all 64 bit of efi_memmap in setup_e820()
