Lifted from http://bugzilla.kernel.org/show_bug.cgi?id=8182
Steps to reproduce:
- Boot an Ocotea board with the mainline 2.6.20.1 kernel.
- Create an /etc/ntp.conf file with at least one NTP server and iburst mode set.
- Issue the command "ntpd -g".
- Wait about two minutes.
- Verify ntpd's status via "ntpq -pn" and by looking in /var/log/ntp.
This fixes this problem by adjusting the expected clock frequency.

Change the configuration of the PCIX PCI->PLB inbound memory window
to be 2GB instead of 512kB. The comment already mentioned 2GB, but the
code unfortunately didn't reflect this.

This patch adds support for the AMCC Taishan PPC440GX evaluation
board.
This is still an arch/ppc port. I'm aware that the move of
4xx to arch/powerpc is making good progress right now. So this
patch is mainly intended to make the Taishan support available
for the community right now.

Fix compilation without PCI support for Bubinga, CPCI405 and EP405.
bios_fixup() for these boards uses functions available only with
CONFIG_PCI, so linker fails.

* Cleaned up interrupt mapping a little by adding a helper
function which parses the irq out of the device-tree, and puts
it into a resource.
* Changed the arch/ppc platform files to specify PHY_POLL, instead of -1
* Changed the fixed phy to use PHY_IGNORE_INTERRUPT
* Added ethtool.h and mii.h to phy.h includes

A find -iname \*.[ch] | xargs grep "> ARRAY_SIZE(" revealed several
incorrect usages of ARRAY_SIZE in the mpc drivers. The last element in the
array is always ARRAY_SIZE()-1, this patch modifies the bounds checks
accordingly.

Remove struct pt_regs * from all handlers.
Also remove the regs argument from get_irq() functions.

Incorporating the new way of cpm2 immr access, introduced in the previous
patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and
powerpc approved working( real actions taken in powerpc only, ppc just
has a wrapper to keep init stuff consistent).

This contains board-specific portion to respect driver changes (for 8272ads ,
885ads and 866ads). Altered platform_data structures as well as initial setup
routines relevant to fs_enet.
Changes to the mpc8560ads ppc/ code are also introduced, but mainly as
reference, since the entire board support is going to appear in arch/powerpc.

screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h. This patches removes the include and modifies all users to
directly include screen_info.h. struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console. Note that this
patch touches every arch and I have no way of testing it. If there is a
mistake the worst thing that will happen is a compile error.

This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.
While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.
The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.
This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.
As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.
The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.
We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.
This patch:
rename desc->handler to desc->chip.
Originally i did not want to do this, because it's a big patch. But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.
I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.
So lets get over with this quickly. The conversion was done automatically
via scripts and converts all the code in the kernel.
This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.
