6bbbca7359 pstore: Pass header size in the pstore write callback
Header size is needed to distinguish between header and the dump data.
Incorporate the addition of new argument (hsize) in the pstore write
callback.

74251fe21b powerpc/powernv: Fix iommu initialization again
So because those things always end up in trainwrecks... In 7846de406
we moved back the iommu initialization earlier, essentially undoing
37f02195b which was causing us endless trouble... except that in the
meantime we had merged 959c9bdd58 (to workaround the original breakage)
which is now ... broken :-)

This fixes it by doing a partial revert of the latter (we keep the
ppc_md. path which will be needed in the hotplug case, which happens
also during some EEH error recovery situations).

88a8e4aa08 i2c: iop3xxx: fix build failure after waitqueue changes
There has long been a syntax problem in iop3xx_i2c_wait_event() which
has been somehow hidden by the macros in <linux/wait.h>.  After some
recent cleanup/rework of the wait_event_* helpers, the bug has come
out from hiding and now results in build failure:
