6b06ebdfbd omap2/3: ZOOM: Correcting key mapping for few keys
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.

9230372aee omap2/3: make serial_in_override() address the right uart port
Commit f62349ee97 makes it possible to
have some other than first uart port as ttyS0, which breaks the workaround
serial_in_override() function which will try to address the first uart
port (for ttyS0) and not the one that was initialized.

66215949e6 omap1: Fix compile for omap1_bl.c
Commit 9905a43b made struct backlight_ops const. Omap was
setting check_fb dynamically, which caused the following
compile error:

drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe':
drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops'

Turns out pdata->check_fb is not being used, so just remove
it to fix the compile.

4318f36b7c omap: gpio: Simultaneously requested rising and falling edge
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).

56aa616a03 GFS2: Ensure uptodate inode size when using O_APPEND
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.

cafe6609d6 drm/radeon/kms: Schedule host path read cache flush through the ring V2
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.

__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

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

This was moved out of the kgdb code and into the

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.

e6be8d9d17 drm: remove address mask param for drm_pci_alloc()
drm_pci_alloc() has input of address mask for setting pci dma
mask on the device, which should be properly setup by drm driver.
And leave it as a param for drm_pci_alloc() would cause confusion
or mistake would corrupt the correct dma mask setting, as seen on
intel hw which set wrong dma mask for hw status page. So remove
it from drm_pci_alloc() function.

87d26d2d11 ARM: S3C64XX: Fix possible clock look in EPLL and MPLL clock chains
There is a possibility of a loop happening in the PLL output clock
chain on the S3C64XX series. clk_mpll's parent was set to be
clk_mout_mpll, but this is fed from clk_fout_epll (which is also
clk_mpll).

clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll
is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll
and thus should be considered a seperate clock.

Anything using clk_mpll directly really should not be relying on this
being the clock that is eventually routed to a peripheral, so remove the
loop and ensure that the clocks accurately represent the clock chain
in the device.

The clk_mpll is not being used outside of the s3c6400-clock.c code, so
this change should not break anything else.

Do the same for the EPLL.

7959722b95 NOMMU: Use copy_*_user_page() in access_process_vm()
The MMU code uses the copy_*_user_page() variants in access_process_vm()
rather than copy_*_user() as the former includes an icache flush.  This
is important when doing things like setting software breakpoints with
gdb.  So switch the NOMMU code over to do the same.

This patch makes the reasonable assumption that copy_from_user_page()
won't fail - which is probably fine, as we've checked the VMA from which
we're copying is usable, and the copy is not allowed to cross VMAs.  The
one case where it might go wrong is if the VMA is a device rather than
RAM, and that device returns an error which - in which case rubbish will
be returned rather than EIO.
