The header files describe the hardware registers available in both
these chips, note that most of this documentation is automatically
generated from the hardware implementation.

The two chips are somewhat different, and needs different handling.

walk_memory_resource() verifies if there are holes in a given memory
range, by checking against /proc/iomem. On x86/ia64 system memory is
represented in /proc/iomem. On powerpc, we don't show system memory as
IO resource in /proc/iomem - instead it's maintained in
/proc/device-tree.
This provides a way for an architecture to provide its own
walk_memory_resource() function. On powerpc, the memory region is
small (16MB), contiguous and non-overlapping. So extra checking
against the device-tree is not needed.

Currently the cell IOMMU fixed mapping just printks that it's been setup,

If we get a 64-bit dma mask we switch to the fixed ops and call
cell_dma_dev_setup(). If the driver then switches back to a 32-bit dma
mask for any reason we don't call cell_dma_dev_setup() again, which
has the potential to leave bogus data in dev->archdata.dma_data.

Stop bits are only valid when the running bit is not set. Status bits
carry over from one invocation of spufs_run_spu() to another, so the
RUNNING bit gets added to the previous state of the register which may
have been a remote library call. In this case, it looks like another
library routine should be invoked, but the spe is actually running.
This fixes a problem with a testcase that exercises the scheduler.

Currently, the kernel may fail to restart a SPE context which
has stopped and been swapped out.
This changes spu_backing_runcntl_write to emulate the real
SPU_Status register exactly. When the SPU Run Control register
is written with SPU_RunCntl[Run] set to '1', the physical SPU
automatically sets SPU_Status[R] and clears SPU_Status[CISHP].

Fix various state_mutex leaks. The worst one was introduced by the
interrutible state_mutex conversion but there've been a few before
too. Notably spufs_wait now returns without the state_mutex held
when returning an error, which actually cleans up some code.

It appears that with the U3 northbridge, if the processor is in NAP
mode the whole time while waiting for an SMU command to complete,
then the SMU will fail. It could be related to the weird backward
mechanism the SMU uses to get to system memory via i2c to the
northbridge that doesn't operate properly when the said bridge is
in napping along with the CPU. That is on U3 at least, U4 doesn't
seem to be affected.
This didn't show before NO_HZ as the timer wakeup was enough to make
it work it seems, but that is no longer the case.
This fixes it by disabling NAP mode on those machines while
an SMU command is in flight.

Update the AT91 MMC driver to use the generic GPIO calls instead of the
AT91-specific calls; and to request (and release) those GPIO signals.
That required updating the probe() fault cleanup codepaths. Now there
is a single sequence for freeing resources, in reverse order of their
allocation. Also that code uses use dev_*() for messaging, and has less
abuse of KERN_ERR.
Likewise with updating remove() cleanup. This had to free the GPIOs,
and while adding that code I noticed and fixed two other problems: it
was poking at a workqueue owned by the mmc core; and in one (rare)
case would try freeing an IRQ that it didn't allocate.

As pci config space is reinitialised on a suspend/resume cycle, the
disabler needs to work its magic at resume time. For symmetry this
change also explicitly enables the controller at suspend time but
it's not strictly necessary.

It is safe for these Kconfig entries to use select because
they select ACPI_WMI, which already has its dependencies
satisfied. This makes Kconfig more user friendly, since
the user selects the driver they want and the dependency
is met for them. Otherwise, the user would have to find
and enable ACPI_WMI to make enabling these drivers possible.

As Pavel Machek has pointed out, the Kconfig entry for WMI is pretty

Rewrite it so that it explains what ACPI-WMI is, and why anyone
would want to enable it.

If userspace passes a unknown match index into em_meta, then
em_meta_change will return an error and the data for the match will
not be set. This then causes an null pointer dereference when the
cleanup is done in the error path via tcf_em_tree_destroy. Since the
tree structure comes kzalloc, it is initialized to NULL.

This patch adds extra information to the mirror status output, so that
it can be determined which device(s) have failed. For each mirror device,
a character is printed indicating the most severe error encountered. The
characters are:
* A => Alive - No failures
* D => Dead - A write failure occurred leaving mirror out-of-sync
* S => Sync - A sychronization failure occurred, mirror out-of-sync
* R => Read - A read failure occurred, mirror data unaffected
This allows userspace to properly reconfigure the mirror set.
