EFI urgent fixes

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()
