357518fa34 [POWERPC] pcibus_to_node fixes
of_node_to_nid returns -1 if the associativity cannot be found. This
means pcibus_to_cpumask has to be careful not to pass a negative index into
node_to_cpumask.

Since pcibus_to_node could be used a lot, and of_node_to_nid is slow (it
walks a list doing strcmps), lets also cache the node in the
pci_controller struct.

Forthcoming machines will extend the FPSCR to 64 bits.  We already

204face4fb [POWERPC] MSI abstraction
Instead of trying to make PPC64 MSI fit in a Intel-centric MSI layer, a
simple short-term solution is to hook the pci_{en/dis}able_msi() calls
and make a machdep call.

The rest of the MSI functions are superfluous for what is needed at this
time.  Many of which can have machdep calls added as needed.

Ben and Michael Ellerman are looking into rewrite the MSI layer to be
more generic.  However, in the meantime this works as a interim
solution.

0f582bc1f2 powerpc: Simplify push_end definition in pci_32.c
The push_end macro in arch/powerpc/kernel/pci_32.c uses integer
division and multiplication to achieve the effect of rounding a
resource end address up and then advancing it to the end of a
power-of-2 sized region.  This changes it to an equivalent computation
that only needs an integer add and OR.  This is partly based on an
earlier patch by Mel Gorman.

bf72aeba2f powerpc: Use 64k pages without needing cache-inhibited large pages
Some POWER5+ machines can do 64k hardware pages for normal memory but
not for cache-inhibited pages.  This patch lets us use 64k hardware
pages for most user processes on such machines (assuming the kernel
has been configured with CONFIG_PPC_64K_PAGES=y).  User processes
start out using 64k pages and get switched to 4k pages if they use any
non-cacheable mappings.

With this, we use 64k pages for the vmalloc region and 4k pages for
the imalloc region.  If anything creates a non-cacheable mapping in
the vmalloc region, the vmalloc region will get switched to 4k pages.
I don't know of any driver other than the DRM that would do this,
though, and these machines don't have AGP.

When a region gets switched from 64k pages to 4k pages, we do not have
to clear out all the 64k HPTEs from the hash table immediately.  We
use the _PAGE_COMBO bit in the Linux PTE to indicate whether the page
was hashed in as a 64k page or a set of 4k pages.  If hash_page is
trying to insert a 4k page for a Linux PTE and it sees that it has
already been inserted as a 64k page, it first invalidates the 64k HPTE
before inserting the 4k HPTE.  The hash invalidation routines also use
the _PAGE_COMBO bit, to determine whether to look for a 64k HPTE or a
set of 4k HPTEs to remove.  With those two changes, we can tolerate a
mix of 4k and 64k HPTEs in the hash table, and they will all get
removed when the address space is torn down.

fab5db97e4 [PATCH] powerpc: Implement support for setting little-endian mode via prctl
This adds the PowerPC part of the code to allow processes to change
their endian mode via prctl.

This also extends the alignment exception handler to be able to fix up
alignment exceptions that occur in little-endian mode, both for
"PowerPC" little-endian and true little-endian.

We always enter signal handlers in big-endian mode -- the support for
little-endian mode does not amount to the creation of a little-endian
user/kernel ABI.  If the signal handler returns, the endian mode is
restored to what it was when the signal was delivered.

We have two new kernel CPU feature bits, one for PPC little-endian and
one for true little-endian.  Most of the classic 32-bit processors
support PPC little-endian, and this is reflected in the CPU feature
table.  There are two corresponding feature bits reported to userland
in the AT_HWCAP aux vector entry.

This is based on an earlier patch by Anton Blanchard.

c5cf0e30bf [PATCH] powerpc: Fix buglet with MMU hash management
Our MMU hash management code would not set the "C" bit (changed bit) in
the hardware PTE when updating a RO PTE into a RW PTE. That would cause
the hardware to possibly to a write back to the hash table to set it on
the first store access, which in addition to being a performance issue,
might also hit a bug when running with native hash management (non-HV)
as our code is specifically optimized for the case where no write back
happens.

Thus there is a very small therocial window were a hash PTE can become
corrupted if that HPTE has just been upgraded to read write, a store
access happens on it, and that races with another processor evicting
that same slot. Since eviction (caused by an almost full hash) is
extremely rare, the bug is very unlikely to happen fortunately.

This fixes by allowing the updating of the protection bits in the native
hash handling to also set (but not clear) the "C" bit, and, in order to
also improve performances in the general case, by always setting that
bit on newly inserted hash PTE so that writeback really never happens.

We can now scan the list of device nodes instead.  This also allows us
to remove the Device_list member of struct pci_dn.

0d177df15d [PATCH] powerpc: move iSeries PCI devices to the device tree
Move the probing of PCI devices to setup.c and put them all into the
flattened device tree.  The later probing is now done by traversing the
device tree.

b58b7f9867 [PATCH] powerpc: tidy up iseries/pci.c
Remove some unused counters.

No need to allocate iomm_table and iobar_table, which means that
iomm_table_initialize is not longer needed.

Use kzalloc where sensible.
