by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git x86/pcid
commit d9da2c95d77fd14360cd902ff1bc3859452bb5bc
Author: Andy Lutomirski <luto(a)kernel.org>
AuthorDate: Sat Dec 19 22:47:44 2015 -0800

CommitDate: Sun Dec 27 05:18:22 2015 -0800
x86/mm: If INVPCID is available, use it to flush global mappings
On my Skylake laptop, INVPCID function 2 (flush absolutely
everything) takes about 376ns, whereas saving flags, twiddling
CR4.PGE to flush global mappings, and restoring flags takes about
539ns.
