SubjectRe: [PATCH v2 2/3] efi: call get_event_log before ExitBootServices
Hi Thiebaud,

[auto build test ERROR on efi/next]
[also build test ERROR on next-20170913]
[cannot apply to char-misc/char-misc-testing linus/master v4.13]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base: next
config: ia64-allmodconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 6.2.0
wget -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=ia64

Note: the linux-review/Thiebaud-Weksteen/Call-GetEventLog-before-ExitBootServices/20170913-221312 HEAD 58dc8ee5de3bb5fb1ef216b80a76102d2de2b141 builds fine.
It only hurts bisectibility.
