Merge tag 'for-v3.10' of git://git.infradead.org/users/cbou/linux-pstore
Pull pstore update from Anton Vorontsov: - A new platform data parameter to specify ECC configuration; - Rounding fixup to not waste memory in ecc_blocks; - Restore ECC information printouts; - A small code cleanup: use kmemdup where appropriate. * tag 'for-v3.10' of git://git.infradead.org/users/cbou/linux-pstore: pstore/ram: Restore ecc information block pstore/ram: Allow specifying ecc parameters in platform data pstore/ram: Include ecc_size when calculating ecc_block pstore: Replace calls to kmalloc and memcpy with kmemdup
