Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Ben Herrenschmidt:
"Here are 3 more small powerpc fixes that should still go into .16.
One is a recent regression (MMCR2 business), the other is a trivial
endian fix without which FW updates won't work on LE in IBM machines,
and the 3rd one turns a BUG_ON into a WARN_ON which is definitely a
LOT more friendly especially when the whole thing is about retrieving
error logs ..."
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc: Fix endianness of flash_block_list in rtas_flash
powerpc/powernv: Change BUG_ON to WARN_ON in elog code
powerpc/perf: Fix MMCR2 handling for EBB
