pxa_gpio_irq_type() and pxa_unmask_muxed_gpio() will touch non-muxed GPIOs
(0 and 1 on PXA2xx/PXA3xx) bits in GRERx and GFERx, which is incorrect.
Actually, only those bits should get updated if the corresponding bits are
set in c->irq_mask as well. Fix this by updating only those relevant bits.

Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12. Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management. GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management. GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator. But on HS devices, it
may not be available for Linux use.
It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12.
This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.
Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of
this patch - thanks Kalle.

The GPIO IRQ enable/disable path attempts to also enable IRQ wake
support for the parent GPIO bank IRQ as well. However, since there is
no 'set_wake' hook for the bank IRQs, these calls will always fail.
Also, since the enable will fail on the suspend path, the disable on
the resume path will trigger unbalanced enable/disable warnings.
This was discovered in the suspend/resume path on OMAP3/Beagle using
the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the
suspend/resume path.

This patch adds sys_preadv and sys_pwritev to ARM.
These syscalls simply take five long-sized parameters, so they

Tested on armv5tel eabi using a preadv/pwritev test program posted

When unmapping N pages (e.g. shared memory) the amount of TLB flushes
done can be (N*PAGE_SIZE/ZAP_BLOCK_SIZE)*N although it should be N at
maximum. With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a
noticeable performance penalty when unmapping a large VMA and the system
is spending its time in flush_tlb_range().
The problem is that tlb_end_vma() is always flushing the full VMA
range. The subrange that needs to be flushed can be calculated by
tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins,
and is also used by other arches.
The speed increase is roughly 3x for 8M mappings and for larger mappings
even more.

to allow board-specific configuration at stream startup and teardown,
and another for pxa2xx-ac97-lib which allows configuration of the reset
GPIO for PXA2xx CPUs.
Obviously this won't actually work when using the generic AC97 driver
since the drivers will attempt to parse the platform data in both
formats. Fix this by merging the two structures.

The platform data for the i2c-s3c2410 driver used to allow a min,
max and desired frequency for the I2C bus. This patch reduces it
to simply a desired frequency ceiling and corrects all the uses
of the platform data appropriately.
This means, for example, that on a system with a 66MHz fclk, a
request for 100KHz will achieve 65KHz which is safe and
acceptable, rather than 378KHz which it would have achieved
without this change.

With the i.MX31 transition to clkdev clock names have changed, but mistakenly
the "mx3-camera.0" has been registered with a non-NULL connection ID, which is
not necessary, since this is the only clock, used by the capture interface
driver. Fix the clock definition and the driver to use NULL as a connection ID.

add the init_data field to struct bq24022_mach_info.

We've observed that ARM VFP state can be corrupted during VFP exception
handling when PREEMPT is enabled. The exact conditions are difficult
to reproduce but appear to occur during VFP exception handling when a
task causes a VFP exception which is handled via VFP_bounce and is then
preempted by yet another task which in turn causes yet another VFP
exception. Since the VFP_bounce code is not preempt safe, VFP state then
becomes corrupt. In order to prevent preemption from occuring while
handling a VFP exception, this patch disables preemption while handling
VFP exceptions.

Because of an ARM1136 erratum (326103), the current v6_early_abort
function needs to set the correct FSR[11] value which determines whether
the data abort was caused by a read or write. For legacy reasons (bit 10
not handled by software), bit 10 was also cleared masking out imprecise
aborts on ARMv6 CPUs. This patch removes the clearing of bit 10 of FSR.

In introducing a trivial "strstarts()" function in linux/string.h, we
hit:
arch/arm/boot/compressed/misc.o: In function `strstarts':
misc.c:(.text+0x368): undefined reference to `strlen'
misc.c:(.text+0x378): undefined reference to `strncmp'
This is because of "CFLAGS_misc.o := -Dstatic=" in the Makefile.
"static inline strstarts(...)" becomes non-inline, and refers to the
other string ops.
The simplest workaround is to include asm/string.h. This makes sense
anyway, since lib/string.c won't be linked against this so we can't
use those functions anyway.
Compile tested here.

I get random oopses on my Kirkwood board at startup when L2 cache is
enabled. FYI I'm using Marvell uboot version 3.4.16
Each boot produces the same oops, but anything that changes the kernel

I noticed that nothing invalidates the L2 cache before enabling it,
doing so fixes my problem.
