Patch from Nicolas Pitre
The cmpxchg emulation on pre-ARMv5 relies on user code executed from a
kernel address. If the operation cannot complete atomically, it is
aborted from the usr_entry macro by clearing the Z flag. This clearing
of the Z flag is done whenever the user pc is above TASK_SIZE.
However this "pc >= TASK_SIZE" test cannot work in the non MMU case.
Worse: the current code will corrupt the Z flag on every entry to the
kernel.
Let's disable it in the non MMU case for now. Using NPTL on non MMU
targets needs to be worked out anyway.

Patch from Nicolas Pitre
struct sockaddr_un loses its padding with EABI. Since the size of the
structure is used as a validation test in unix_mkname(), we need to
change the length argument to 110 whenever it is 112.

Patch from Nicolas Pitre
Although OABI_COMPAT works fine in most cases, it is still experimental
and could be for ever since it is nearly impossible to handle
everything, e.g. ioctls.

Patch from Ben Dooks
Move to using an enable count for the shared clocks
and protect the clock system using a mutex instead
of just disabling IRQs during the clock update.
Since there is little more code in the path for
non-shared clocks, the enable and disable calls
use the same code for each.

Patch from Lennert Buytenhek
Most ixp2000 boards don't actually work if pci=firmware isn't used, so
the defconfig isn't really the right place to specify this. Instead of
specifying it in the defconfigs, make the relevant board code take care
of setting pci=firmware.

Patch from Lennert Buytenhek
The ixdp2x01_clock is already 50MHz by default, so no need to
override it with 50MHz in the ixdp2801 defconfig as is done now,
which is confusing as well.

Patch from Lennert Buytenhek
The ixdp2x01 pci init call doesn't check whether it's really running
on an ixdp2x01, making it impossible to compile one kernel that works
on both the ixdp2x01 and another ixp2000 board.

This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

The PowerMac sound drivers used to rely on a "bug" of the i2c-keywest
driver that implemented I2C_SMBUS_BLOCK_DATA incorrectly, that is it did
what I2C_SMBUS_I2C_BLOCK_DATA should have done. The new i2c-powermac
driver that replaces keywest has this bug fixed, thus the sound drivers
must be fixed too.

Direct backport of 2.4 fix that didn't get propagated to 2.6; original
comment follows:
<quote>
When I specify the NFS port for nfsroot (e.g.,
nfsroot=<dir>,port=2049), the
kernel uses the wrong port. In my case it tries to use 264 (0x108)
instead
of 2049 (0x801).
This patch adds the missing htons().
