Merge tag 'for-v3.7' of git://git.infradead.org/users/cbou/linux-pstore
Pull pstore changes from Anton Vorontsov:
1) We no longer ad-hoc to the function tracer "high level"
infrastructure and no longer use its debugfs knobs. The change
slightly touches kernel/trace directory, but it got the needed ack
from Steven Rostedt:
http://lkml.org/lkml/2012/8/21/688
2) Added maintainers entry;
3) A bunch of fixes, nothing special.
* tag 'for-v3.7' of git://git.infradead.org/users/cbou/linux-pstore:
pstore: Avoid recursive spinlocks in the oops_in_progress case
pstore/ftrace: Convert to its own enable/disable debugfs knob
pstore/ram: Add missing platform_device_unregister
MAINTAINERS: Add pstore maintainers
pstore/ram: Mark ramoops_pstore_write_buf() as notrace
pstore/ram: Fix printk format warning
pstore/ram: Fix possible NULL dereference
