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
