Subject[GIT pull] EFI fix for 5.6-rc1
Linus,

please pull the latest efi/urgent branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git efi-urgent-2020-02-09

up to: 59365cadfbcd: efi/x86: Fix boot regression on systems with invalid memmap entries


A single fix for a EFI boot regression on X86 which was caused by the
recent rework of the EFI memory map parsing. On systems with invalid memmap
entries the cleanup function uses an value which cannot be relied on in
this stage. Use the actual EFI memmap entry instead.


Thanks,

tglx
