In OMAP2/3 some of the clock-domains which did not have control
facility were being falsely written to and read using the CM_CLKSTCTRL
register though it did not exist for them. One check is added to remove
this flaw.

Keys: 'right arrow', 'up arrow' and 'select' were mapped
wrongly. This patch corrects them.
This patch also adds one missing key present in the board,
currently I added it as 'unknown' key, as I am not able to
find proper description for this key.
One key entry (r: 7, c: 5) is present in the keymap, which
is really not present in the board, removing it.

Some chips, namely any OMAP1 chips using METHOD_MPUIO,
OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO
interrupts in both rising and falling edge directions -- they can
only respond to one direction or the other, depending on how the
ICR is configured.
Additionally, current code forces rising edge detection if both
flags are specified:
if (trigger & IRQ_TYPE_EDGE_RISING)
l |= 1 << gpio;
else if (trigger & IRQ_TYPE_EDGE_FALLING)
l &= ~(1 << gpio);
else
goto bad;
This change implements a toggle function that will modify the ICR
to flip the direction of interrupt for IRQs that are requested with
both rising and falling flags. The toggle function is not called
for chips and GPIOs it does not apply to through the use of a flip_mask
that's added on a per-bank basis. The mask is only set for those
GPIOs where a toggle is necessary. Edge detection starts out the
same as above with FALLING mode first.
The toggle happens on EACH interrupt; without it, we have the
following sequence of actions on GPIO transition:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt
0x1 1 -> 0 (falling) No interrupt
(set ICR to 0x0 manually)
0x0 0 -> 1 (rising) No interrupt
0x0 1 -> 0 (falling) Interrupt
That is, with the ICR set to 1 for a gpio, only rising edge interrupts
are caught, and with it set to 0, only falling edge interrupts are
caught. If we add in the toggle, we get this:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0)
0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1)
0x1 0 -> 1 ...
so, both rising and falling are caught, per the request for both
(IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

The rename code was taking a resource group lock in cases where
it wasn't actually needed, this caused problems if the rename

The VFS reads the inode size during generic_file_aio_write() but
with no locking around it. In order to get the expected result
from O_APPEND opens, this patch updated the inode size before
calling generic_file_aio_write()
There is of course still a race here, in that there is nothing to
prevent another node coming in and extending the file in the
mean time. On the other hand, when used with file locking this
will ensure that the expected results are obtained.

R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.
Tested on R100,R200,R300,R400,R500,R600,R700 family.

__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096
systems it hogs 16MB of memory. This is way too much for a quite
probably unused facility (only KVM uses dynamic TR registers).
Change to an array of pointers, and allocate entries as needed on
a per cpu basis. Change the name too as the __per_cpu_ prefix is
confusing (this isn't a classic <linux/percpu.h> type object).

Blackfin needs it own arch specific probe_kernel_read() and
probe_kernel_write().
This was moved out of the kgdb code and into the
arch/blackfin/maccess.c, because it is a generic kernel api.
The arch specific kgdb.c for blackfin was cleaned of all functions
which exist in the kgdb core that do the same thing after resolving
the probe_kernel_read() and probe_kernel_write(). This also
eliminated the need for most of the #include's.
