seem to be any place where G is set without also setting I (_PAGE_NO_CACHE),

0f47331475 powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPAT
Background from Maynard Johnson:
As of POWER6, a set of 32 common events is defined that must be
supported on all future POWER processors.  The main impetus for this
compat set is the need to support partition migration, especially from
processor P(n) to processor P(n+1), where performance software that's
running in the new partition may not be knowledgeable about processor
P(n+1).  If a performance tool determines it does not support the
physical processor, but is told (via the
PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports
the notion of the PMU compat set, then the performance tool can
surface just those events to the user of the tool.

PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at
least this basic subset of events which is compatible across POWER
processor lines.

_greater zero_ (0x08 = default) since setting it to 0x00 leads to
_very poor_ performance as a PCI target since external burst won't be

Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance.

c356aa456e powerpc/bootwrapper: Allow user to specify additional default targets
It is inconvenient to add additional default targets to the bootwrapper
Makefile for each new board supported which just needs a different dts
file.  This change allows the defconfig to specify additional build
targets.

cde274c0c7 powerpc/eeh: PERR/SERR bit settings during EEH device recovery
The following patch restores the PERR and SERR bits in the PCI
command register during an EEH device recovery. We have found
at least one case (an Agilent test card) where the PERR/SERR
bits are set to 1 by firmware at boot time, but are not restored
to 1 during EEH recovery.  The patch fixes the Agilent card
problem.  It has been tested on several other EEH-enabled cards
with no regressions.
