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 stored in a file named [dmesg-nvram-2]. 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 --- Aruna Balakrishnaiah (8): powerpc/pseries: Remove syslog prefix in uncompressed oops text powerpc/pseries: Add version and timestamp to oops header powerpc/pseries: Introduce generic read function to read nvram-partitions powerpc/pseries: Read/Write oops nvram partition via pstore powerpc/pseries: Read rtas partition via pstore powerpc/pseries: Distinguish between a os-partition and non-os partition powerpc/pseries: Read of-config partition via pstore powerpc/pseries: Read common partition via pstore arch/powerpc/platforms/pseries/nvram.c | 353 +++++++++++++++++++++++++++----- fs/pstore/inode.c | 9 + include/linux/pstore.h | 4 3 files changed, 313 insertions(+), 53 deletions(-) --
