Commit 74e400cee6 (powerpc: Rework setting up H/FSCR bit definitions)
ended up with incorrect bit numbers for FSCR_PM_LG and FSCR_BHRB_LG.
This fixes them.

These eeproms are never used by kernel. So no need to add them.

Idle routines on pseries were rearranged so that cpuidle can do an

Naturally, EEH has been supported for PHB3, but we had some mask bits
to disable it because the firmware isn't ready. The series of patch

the output messages from EEH has been reordered to reflect the correct

The patch prints the error number while failing to retrieve error
log from firmware. It's helpful for debugging.

We already had some output messages from EEH core. Occasionally,
we can see the output messages from EEH core before the stack
dump. That's not what we expected. The patch fixes that and shows
the stack dump prior to output messages from EEH core.

Each PHB instance (struct pnv_phb) has its corresponding log blob,
which is used to hold the retrieved error log from firmware. The
current size of that (4096) isn't enough for PHB3 case and the patch
makes that double to 8192.

release but this contains a lot of fixes all over arch/powerpc to use the
