Subject: [PATCH v5 00/12] pstore: mtd: support crash log to block and mtd device

This is a series to support crash log to block and mtd device,
base on v4 of Kees Cook's.

Changes since v4:
	patch 1: adapt pstore to kmsg_dump_reason_str().
	patch 2: fix bugs that decompress failed and rmmod failed.
			 use atomic_xchg() on psz_flush_dirty_zone() in case of reload.
	patch 3: fix build error
	patch 5: flush pmsg zone if it's dirty.
	patch 6: use delayed work to cache more data and reduce calling
			 dirty-flusher times
	patch 12: change dev_err() to pr_err() when initialize because it get
			  no pointer to mtd at that time.
