07d5ecae29 arm: Remove bogus comment in futex_atomic_cmpxchg_inatomic()
commit 522d7dec(futex: Remove redundant pagefault_disable in
futex_atomic_cmpxchg_inatomic()) added a bogus comment.

/* Note that preemption is disabled by futex_atomic_cmpxchg_inatomic
 * call sites. */

Bogus in two aspects:

1) pagefault_disable != preempt_disable even if the mechanism we use
   is the same

2) we have a call site which deliberately does not disable pagefaults
   as it wants the possible fault to be handled - though that has been
   changed for consistency reasons now.

Sigh. I really should have seen that when committing the above. :(

37a9d912b2 futex: Sanitize cmpxchg_futex_value_locked API
The cmpxchg_futex_value_locked API was funny in that it returned either
the original, user-exposed futex value OR an error code such as -EFAULT.
This was confusing at best, and could be a source of livelocks in places
that retry the cmpxchg_futex_value_locked after trying to fix the issue
by running fault_in_user_writeable().
    
This change makes the cmpxchg_futex_value_locked API more similar to the
get_futex_value_locked one, returning an error code and updating the
original value through a reference argument.

This patch modifies the number of total GPIO lines for Bank F
for Samsung S5P6440 and S5P6450 SoCs from 2 to 16.
This is necessary as the GPIO lines from 0 to 13 are reserved
and only lines 14 and 15 are used. As during initialization,
the line number starts at 0, putting 2 does not solve the

Temporary strings with volt_* file names should be released after the

c284d9fa48 davinci: tnetv107x: fix register indexing for GPIOs numbers > 31
This patch fix a bug in the register indexing for GPIOs numbers >  31
to get the relevant hardware registers of tnetv107x to control the GPIOs.

In the structure tnetv107x_gpio_regs:

struct tnetv107x_gpio_regs {
            u32     idver;
            u32     data_in[3];
            u32     data_out[3];
            u32     direction[3];
            u32     enable[3];
};

The GPIO hardware register addresses of tnetv107x are stored.
The chip implements 3 registers of each entity to serve 96 GPIOs,
each register provides a subset of 32 GPIOs.
The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit
and gpio_reg_clear_bit.

The bug implied the use of macros to access the relevant hardware
register e.g. the driver code used the macro like this:
'gpio_reg_clear_bit(&reg->data_out, gpio)'

But it has to be used like this:
'gpio_reg_clear_bit(reg->data_out, gpio)'.

The different results are shown here:
- &reg->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes)
- reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes)

51c404b2c5 omap4: prcm: Fix the CPUx clockdomain offsets
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base.
The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power
domain control register

Fix the same.

The autogen scripts is fixed thanks to Benoit Cousson

With the old value, the clockdomain code would access the
*_PWRSTCTRL.POWERSTATE field when it thought it was accessing the
*_CLKSTCTRL.CLKTRCTRL field.  In the worst case, this could cause
system power management to behave incorrectly.

cbc9438075 OMAP2+: clocksource: fix crash on boot when !CONFIG_OMAP_32K_TIMER
OMAP2+ kernels built without CONFIG_OMAP_32K_TIMER crash on boot after the
2.6.38 sched_clock changes:

[    0.000000] OMAP clockevent source: GPTIMER1 at 13000000 Hz

[    0.000000] LR is at sched_clock_poll+0x2c/0x3c

Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and
clocksource resolution about three orders of magnitude higher than
with CONFIG_OMAP_32K_TIMER set.  The tradeoff is that the lowest
power consumption states are not available.

Fix by calling init_sched_clock() from the GPTIMER clocksource init code.
