  pstore/ram: (really) fix undefined usage of rounddown_pow_of_two (2013-08-30 15:57:01 -0700)

----------------------------------------------------------------
Big part of this is the addition of compression to the
generic pstore layer so that all backends can use the
pitiful amounts of storage they control more effectively.
Three other small fixes/cleanups too.

Aruna Balakrishnaiah (11):
      powerpc/pseries: Remove (de)compression in nvram with pstore enabled
      pstore: Add new argument 'compressed' in pstore write callback
      pstore/Kconfig: Select ZLIB_DEFLATE and ZLIB_INFLATE when PSTORE is selected
      pstore: Add compression support to pstore
      pstore: Introduce new argument 'compressed' in the read callback
      pstore: Add decompression support to pstore
      pstore: Add file extension to pstore file if compressed
