c17e3325ba ppc64: Use SPRN_ prefix for special purpose register names
Now that we are using the merged reg.h we have to use the SPRN_xxx
names rather than the xxx names.

b5bbeb2373 powerpc: Use SPRN_xxx rather than xxx for SPR numbers
This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to
special purpose registers to SPRN_HID0, SPRN_SPRG3, etc.  Using the
SPRN_ symbols clutters the namespace less, and the forthcoming merge
of asm/processor.h and asm/reg.h is going to remove the non-SPRN_
versions.

0f9578b70a [PATCH] ppc64: More hugepage fixes
My previous patch fixing invalidation of huge PTEs wasn't good enough, we
still had an issue if a PTE invalidation batch contained both small and
large pages.  This patch fixes this by making sure the batch is flushed if
the page size fed to it changes.

67b108131d [PATCH] ppc64: Fix huge pages MMU mapping bug
Current kernel has a couple of sneaky bugs in the ppc64 hugetlb code that
cause huge pages to be potentially left stale in the hash table and TLBs
(improperly invalidated), with all the nasty consequences that can have.

One is that we forgot to set the "secondary" bit in the hash PTEs when
hashing a huge page in the secondary bucket (fortunately very rare).

The other one is on non-LPAR machines (like Apple G5s), flush_hash_range()
which is used to flush a batch of PTEs simply did not work for huge pages.
Historically, our huge page code didn't batch, but this was changed without
fixing this routine.  This patch fixes both.

0365ba7fb1 [PATCH] ppc64: SMU driver update & i2c support
The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5.  It drives things like fans, i2c busses, real time
clock, etc...

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

586a90eb4c [PATCH] ppc64: Fix LPAR regression
The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes.

It looks like we have been calling the non LPAR iommu_dev_setup on LPAR
machines for a while. The recent iommu fix caused that code path to
fail.

It looks like we just need to hook up the devices iommu_table to the
parents one, so do that instead of calling iommu_dev_setup_pSeries and
crossing the streams.
