Subject: [GIT pull] efi updates for 4.18

Linus,

please pull the latest efi-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git efi-urgent-for-linus

Two fixlets for the EFI maze:

  - Properly zero variables to prevent an early boot hang on EFI mixed mode
    systems

  - Fix the fallout of merging the 32bit and 64bit variants of EFI PCI
    related code which ended up chosing the 32bit variant of the actual EFi
    call invocation which leads to failures on 64bit.

Thanks,

	tglx
