The patch to legacy_serial.c (1a7507c7da2df6856e085e0fbb0c9ea8c12ac4e,
Reduce code duplication in legacy_serial, add UART parent types) changed
the semantics for opb ports from type = "opb" || compatible = "ibm,opb"
to type = "opb" && compatible = "ibm,opb".
The result is serial ports on our QS21s (Cell blades) don't get found,
and for some reason the machine doesn't boot at all - possibly it's
panicking due to lack of a console?
The fix is to add two entries to the of_device_id table, one that looks
for type = "opb" and the other compatible = "ibm,opb".

I got this warning from gcc:
arch/powerpc/platforms/cell/axon_msi.c:118: warning: 'tmp' may be used uninitialized in this function
Which turns out to be a false positive, but pointed out that it was
possible for the error path in find_msi_translator() to do an extra
of_node_put on a node. This fixes it by localising the ref counting
a bit. As a side effect, the warning goes away.

There's a brown-paper-bag bug in axon_msi, we pass the address of our
FIFO directly to the hardware, without DMA mapping it. This leads to
DMA exceptions if you enable MSI & the IOMMU.
The fix is to correctly DMA map the fifo, dma_alloc_coherent() does
what we want - and we need to track the virt & phys addresses.

Now that we create of_platform devices earlier on cell, we can make the
axon_msi driver an of_platform driver. This makes the code cleaner in
several ways, and most importantly means we have a struct device.

Currently cell publishes OF devices at device_initcall() time, which
means the earliest a driver can bind to a device is also device_initcall()
time. We have a driver we want to register before other devices, so
publish the devices at subsys_initcall() time.
This should not cause any behaviour change for existing drivers, as they
are still bound at device_initcall() time.

This adds markers two important points in the spufs code and a new

(with Martin Schwidefsky <schwidefsky@de.ibm.com>)
The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument. The free functions do not get the mm_struct argument. This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.

Previously, during initialization of the IOMMU tables, the last entry
at each 4GB boundary is marked as used since there are many adapters
which cannot handle DMAing across any 4GB boundary.
The IOMMU doesn't allocate a memory area spanning LLD's segment
boundary anymore. The segment boundary of devices are set to 4GB by
default. So we can remove 4GB boundary protection now.

Linus:
On the per-architecture side, I do think it would be better to *not* have
internal architecture knowledge in a generic file, and as such a line like
depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
really shouldn't exist in a file like kernel/Kconfig.instrumentation.
It would be much better to do
depends on ARCH_SUPPORTS_KPROBES
in that generic file, and then architectures that do support it would just
have a
bool ARCH_SUPPORTS_KPROBES
default y
in *their* architecture files. That would seem to be much more logical,
and is readable both for arch maintainers *and* for people who have no
clue - and don't care - about which architecture is supposed to support
which interface...
Changelog:
Actually, I know I gave this as the magic incantation, but now that I see
it, I realize that I should have told you to just use
config KPROBES_SUPPORT
def_bool y
instead, which is a bit denser.
We seem to use both kinds of syntax for these things, but this is really

On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails. All platforms that use the .set_target() global
suspend callback are affected by analogous issues.
For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful. Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).
Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().

This patch adds support for setting up a fixed IOMMU mapping on certain
cell machines. For 64-bit devices this avoids the performance overhead of
mapping and unmapping pages at runtime. 32-bit devices are unable to use
the fixed mapping.
The fixed mapping is established at boot, and maps all of physical memory
1:1 into device space at some offset. On machines with < 30 GB of memory
we setup the fixed mapping immediately above the normal IOMMU window.
For example a machine with 4GB of memory would end up with the normal
IOMMU window from 0-2GB and the fixed mapping window from 2GB to 6GB. In
this case a 64-bit device wishing to DMA to 1GB would be told to DMA to
3GB, plus any offset required by firmware. The firmware offset is encoded
in the "dma-ranges" property.
On machines with 30GB or more of memory, we are unable to place the fixed
mapping above the normal IOMMU window as we would run out of address space.
Instead we move the normal IOMMU window to coincide with the hash page
table, this region does not need to be part of the fixed mapping as no
device should ever be DMA'ing to it. We then setup the fixed mapping
from 0 to 32GB.

The break_lock data structure and code for spinlocks is quite nasty.
Not only does it double the size of a spinlock but it changes locking to
a potentially less optimal trylock.
Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a
__raw_spin_is_contended that uses the lock data itself to determine whether
there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is
not set.
Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to
decouple it from the spinlock implementation, and make it typesafe (rwlocks
do not have any need_lockbreak sites -- why do they even get bloated up
with that break_lock then?).

This patch consolidate all definitions of .init.text, .init.data
and .exit.text, .exit.data section definitions in
the generic vmlinux.lds.h.
This is a preparational patch - alone it does not buy
us much good.

This patch converts the remaining 83xx boards to the dts-v1 format.
This includes the mpc8313_rdb, mpc832x_mds, mpc8323_rdb, mpc8349emitx,
mpc8349emitxgp and the mpc836x_mds.
The mpc8315_rdb mpc834x_mds, mpc837[789]_*, and sbc8349 were already
dts-v1 and only undergo minor changes for the sake of formatting
consistency across the whole group of boards; i.e. the idea being
that you can do a "diff -u board_A.dts board_B.dts" and see something
meaningful.
The general rule I've applied is that entries for values normally
parsed by humans are left in decimal (i.e. IRQ, cache size, clock
rates, basic counts and indexes) and all other data (i.e. reg and
ranges, IRQ flags etc.) remain in hex.
I've used dtc to confirm that the output prior to this changeset
matches the output after this changeset is applied for all boards.

All current 85xx/e500 implementations only have two TLB
arrays. We are wasting cycles by invalidating TLB2 and TLB3.
