The VIA Padlock device is able to perform much better when multiple
blocks are fed to it at once. As this device offers an exceptional
throughput rate it is worthwhile to optimise the infrastructure
specifically for it.
We shift the existing page-sized fast path down to the CBC/ECB functions.
We can then replace the CBC/ECB functions with functions provided by the
underlying algorithm that performs the multi-block operations.
As a side-effect this improves the performance of large cipher operations
for all existing algorithm implementations. I've measured the gain to be
around 5% for 3DES and 15% for AES.

Checking a pointer for NULL before calling kfree() on it is redundant.
This patch removes such checks from crypto/

The membar changes made the size of __cheetah_flush_tlb_pending
grow by one instruction, but the boot-time code patching was
not updated to match.

The following renames arch_init, a kprobes function for performing any
architecture specific initialization, to arch_init_kprobes in order to
cleanup the namespace.
Also, this patch adds arch_init_kprobes to sparc64 to fix the sparc64 kprobes
build from the last return probe patch.

Add explicit disabling of 440GP IRQ compatibility mode when configuring
440GX interrupt controller. This helps when board firmware for some reason
uses this compatibility mode and leaves it enabled. It breaks 440GX
interrupt code because it assumes native 440GX IRQ mode. People seems to
be continuously bitten by this.

As part of my timeofday rework, I've been looking at the NTP code and I
noticed that the PPC architecture is apparently misusing the NTP's
time_offset (it is a terrible name!) value as some form of timezone offset.
This could cause problems when time_offset changed by the NTP code. This
patch changes the PPC code so it uses a more clear local variable:
timezone_offset.

This patch adds the Freescale MPC86xADS board support. The supported
devices are SMC UART and 10Mbit ethernet on SCC1.
The manual for the board says that it "is compatible with the MPC8xxFADS
for software point of view". That's why this patch extends FADS instead of
introducing a new platform.
FEC is not supported as the "combined FCC/FEC ethernet driver" driver by
Pantelis Antoniou should replace the current FEC driver.
