d0afc85f15 [ARM] colibri: fix support for DM9000 ethernet device
Two changes are necessary to enable proper operation of the DM9000 device with
the Colibri PXA 270 board: firstly, the IRQ type needs to be configured for
rising edge interrupts, and secondly this configuration needs to be
communicated through to the DM9000.

bbdf1c1e58 [ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisation
Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.

This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.)  However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.

This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.

b3a8b751c1 [ARM] 5034/1: fix arm{925,926,940,946} dma_flush_range() in WT mode
The CPU's dma_flush_range() operation needs to clean+invalidate the
given memory area if the cache is in writeback mode, or do just the
invalidate part if the cache is in writethrough mode, but the current
proc-arm{925,926,940,946} (incorrectly) do a cache clean in the
latter case.  This patch fixes that.

8e3e076c5a BKL: revert back to the old spinlock implementation
The generic semaphore rewrite had a huge performance regression on AIM7
(and potentially other BKL-heavy benchmarks) because the generic
semaphores had been rewritten to be simple to understand and fair.  The
latter, in particular, turns a semaphore-based BKL implementation into a
mess of scheduling.

The attempt to fix the performance regression failed miserably (see the
previous commit 00b41ec261 'Revert
"semaphore: fix"'), and so for now the simple and sane approach is to
instead just go back to the old spinlock-based BKL implementation that
never had any issues like this.

This patch also has the advantage of being reported to fix the
regression completely according to Yanmin Zhang, unlike the semaphore
hack which still left a couple percentage point regression.

As a spinlock, the BKL obviously has the potential to be a latency
issue, but it's not really any different from any other spinlock in that
respect.  We do want to get rid of the BKL asap, but that has been the
plan for several years.

These days, the biggest users are in the tty layer (open/release in
particular) and Alan holds out some hope:

  "tty release is probably a few months away from getting cured - I'm
   afraid it will almost certainly be the very last user of the BKL in
   tty to get fixed as it depends on everything else being sanely locked."

so while we're not there yet, we do have a plan of action.

9096bd7a66 x86: restrict keyboard io ports reservation to make ipmi driver work
On some of our (single board computer) boards (x86) we are using an
IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard
controller style) IPMI system interface.

Trying to load the openipmi driver fails, because the ports
(0x62/0x66) are reserved for keyboard. keyboard reserves the full
range 0x60-0x6F while it doesn't need to.

Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad
controller instead of 0x60-0x6F to allow the openipmi driver to work.

5bf6c6e30d [ARM] 5033/1: Unbreak corgi_ssp by registering ssp drivers earlier.
A lot of stuff in spitz/akita/etc. depends on corgi_ssp to be initialised
early. However corgi_ssp initialisation fails, because at that time pxa*-ssp
devices don't have drivers. Move ssp earlier in the makefile so they are
registered before corgi-ssp.

Also move sleep/suspend and cpu-freq to more logical places

24d9649574 [POWERPC] Document when printk is useable
When debugging early boot problems, it's common to sprinkle printk's
all over the place.  However, on 64-bit powerpc, this can lead to
memory corruption if done too early due to the PACA pointer and
lockdep core not being initialized.

This adds some comments to early_setup() that document when it is
safe to do so in order to save time for whoever has to debug that
stuff next.

1b70c5a649 [POWERPC] Fix bogus paca->_current initialization
When doing lockdep, I had two patches to initialize paca->_current
early, one bogus, and one correct.  Unfortunately both got merged
as the bad one ended up being part of the main lockdep patch by
mistake.  This causes memory corruption at boot.  This removes
the offending code.

76bc080ef5 [POWERPC] Make default cputable entries reflect selected CPU family
Changes the cputable so that various CPU families that have an exclusive
CONFIG_ option have a more sensible default entry to use if the specific
processor hasn't been identified.

This makes the kernel more generally useful when booted on an unknown
PVR for things like new 4xx variants.
