Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull livepatching fixes from Jiri Kosina:
- symbol lookup locking fix, from Miroslav Benes
- error handling improvements in case of failure of the module coming
notifier, from Minfei Huang
- we were too pessimistic when kASLR has been enabled on x86 and were
dropping address hints on the floor unnecessarily in such case. Fix
from Jiri Kosina
- a few other small fixes and cleanups
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching:
livepatch: add module locking around kallsyms calls
livepatch: annotate klp_init() with __init
livepatch: introduce patch/func-walking helpers
livepatch: make kobject in klp_object statically allocated
livepatch: Prevent patch inconsistencies if the coming module notifier fails
livepatch: match return value to function signature
x86: kaslr: fix build due to missing ALIGN definition
livepatch: x86: make kASLR logic more accurate
x86: introduce kaslr_offset()
