Subject: [init] BUG: unable to handle kernel NULL pointer dereference at
00000000000000ac
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/apic
commit 30b8b0066cafef274fc92462578ee346211ce7cb
Author: Thomas Gleixner <tglx@...utronix.de>
AuthorDate: Thu Jan 15 21:22:39 2015 +0000
Commit: Thomas Gleixner <tglx@...utronix.de>
CommitDate: Thu Jan 22 15:10:56 2015 +0100
init: Get rid of x86isms
The UP local API support can be set up from an early initcall. No need
for horrible hackery in the init code.
