Impact: remove false positive warning
After a cpu was taken down during cpu hotplug (read: disabled for interrupts)
it still might have pending softirqs. However take_cpu_down makes sure
that the idle task will run next instead of ksoftirqd on the taken down cpu.
The idle task will call tick_nohz_stop_sched_tick which might warn about
pending softirqs just before the cpu kills itself completely.
However the pending softirqs on the dead cpu aren't a problem because they
will be moved to an online cpu during CPU_DEAD handling.
So make sure we warn only for online cpus.

During a reset, releasing the swflag after it failed to be acquired would
cause a double unlock of the mutex. Instead, test whether acquisition of
the swflag was successful and if not, do not release the swflag. The reset
must still be done to bring the device to a quiescent state.

Implements the KS8695 ethernet device (ks8695net).
This driver is only of use on the KS8695 which is an ARM9 based SoC. The
documentation on this SoC is sparse and poor, with barely a register
description and a rough outline of how the ethernet works, this driver was
therefore written with strong reference to the Micrel supplied Linux 2.6.9
port, and to Andrew Victor's ks8695eth driver.

With this patch the L2 cache is enabled on Canyonlands to increase the
overall performance. There is a known cache coherency issue with the L2
cache, but this is related to the high bandwidth (HB) PLB segment where
the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped
to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe
to enable the L2 cache.

Instead of implementing our own checks use inode_change_ok to check for
necessary permission in setattr. There is a slight change in behaviour
as inode_change_ok doesn't allow i_mode updates to add the suid or sgid

those bits from the file mode.

Instead of doing directly assignment of file operations that set an

in the normal file operations.

Check for the project ID after attaching all inodes to the transaction.
That way the unlock in the error case is done by the transaction subsystem,
which guaratees that is uses the right flags (which was wrong from day one
of this check), and avoids having special code unlocking an array of inodes
with potential duplicates. Attaching the inode first is the method used
by xfs_rename and the other namespace methods all other error that require
multiple locked inodes.

The GPTIMER TLDR register does not need to be written if the GPTIMER
is not in autoreload mode. This is the usual case for dynamic tick-enabled
kernels.
Simulation data indicate that skipping the read that occurs as part of
the write should save at least 300-320 ns for each GPTIMER1 timer
reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write
posting is enabled.) Skipping the write itself probably won't have
much impact since it should be posted on the OCP interconnect.
