Subject: [PATCH v4 0/8] Nvram-to-pstore

Currently the kernel provides the contents of p-series NVRAM only as a
simple stream of bytes via /dev/nvram, which must be interpreted in user
space by the nvram command in the powerpc-utils package. This patch set
exploits the pstore subsystem to expose each partition in NVRAM as a
separate file in /dev/pstore. For instance, Oops messages will be stored
in a file named [dmesg-nvram-2].

Changes from v3:
	- Change filename prefix for of-config and common partition

Changes from v2:
	- Fix renaming of pstore type ids in nvram.c

Changes from v1:
	- Reduce #ifdefs by and remove forward declarations of pstore callbacks
	- Handle return value of nvram_write_os_partition
	- Remove empty pstore callbacks and register pstore only when pstore
	  is configured
