[Blackfin] arch: Fix BUG gpio_direction_output API is not compatitable with GENERIC_GPIO API interface
[Blackfin] arch: Initial checkin of the memory protection support.
[Blackfin] arch: set_bfin_dma_config shouldnt set SYNC or RESTART by default - add argument or option
[Blackfin] arch: Add some comments - fix semicolons
[Blackfin] arch: move all code related to CPLB handling into a new subdirectory under kernel/
[Blackfin] arch: print out list of modules if kernel is crashing and tell people if the kernel is tainted
[Blackfin] arch: enable generic GPIO based I2C driver in STAMP-BF533, EZKIT-BF533 and EZKIT-BF561 boards
[Blackfin] arch: Don't oops_in_progress if single step is comming from the kernel
[Blackfin] arch: Fix BUG - kernel sometimes would stuck with KEYBOARD_GPIO on
[Blackfin] arch: update to latest anomaly sheets
...

Add polling I2C transfer implementation for PXA I2C. This is needed
for cases where I2C transactions have to occur at times interrups are
disabled.

Move the tps65010 header file from the OMAP arch directory to the
more generic <linux/i2c/...> directory, and remove the spurious
dependency of this driver on OMAP.

Migrate all ixp4xx devices to the bitbanging I2C bus driver utilizing
the arch-neutral GPIO API (linux/i2c-gpio.h).
Tested by the nslu2-linux and openwrt projects in public firmware releases.

In s390's spin_lock_irqsave, interrupts remain disabled while
spinning. In other architectures like x86 and powerpc, interrupts are
re-enabled while spinning if IRQ is not masked before spin_lock_irqsave
is called.
The following patch re-enables interrupts through local_irq_restore
while spinning for a lock acquisition.
This can improve system response.

This patch adds the s390 variant for smp_call_function_mask(). The
implementation is pretty straight forward using the wrapper
__smp_call_function_map() which already takes a cpumask_t argument.

This patch fixes a problem with the following scenario:
1. Linux booted from DASD "A"
2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device"
3. Reboot DASD "B"
Without this patch in step 3 on newer s390 systems under LPAR instead of
DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW
reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not
notice the CCW reipl and still thinks that it has to reboot DASD "A".
Before applying this fix, ensure to have MCF RJ9967101E or z9 GA3 base driver
installed.

We have seen an oops in an OOM situation, where show_mem tried to
access the struct page of a dcss segment. The vmemmap code has
already created the 1:1 mapping but failed allocating the struct
pages. In the OOM case, show_mem now walks the memory. It uses
pfn_valid to detect if it may access the struct page. In the case
described above, the mapping was established and pfn_valid returned
true. As the struct pages were not allocated, the kernel oopsed.
We have to ensure that we have created the struct pages, before we
add a mapping pointing to the pages.

In case of a kernel panic it is currently possible to specify that a dump
should be created, the system should be rebooted or stopped. Virtual sysfs
files under the directory /sys/firmware/ are used for that configuration.
In addition to that, there are kernel parameters 'vmhalt', 'vmpoff'
and 'vmpanic', which can be used to specify z/VM commands, which are
automatically executed in case of halt, power off or a kernel panic.
This patch combines both functionalities and allows to specify the z/VM CP
commands also via sysfs attributes. In addition to that, it enhances the
existing handling of shutdown triggers (e.g. halt or panic) and associated
shutdown actions (e.g. dump or reipl) and makes it more flexible.
