The calculation for the Master clock divisor (MDIV) is different on the

Orignal patch from Sascha Erlacher.

Also use the defined AT91_PMC_PRES instead of hard-coded bitmasks.

Subject: [ARM] 4650/1: AT91: New-style init of I2C, support for i2c-gpio

The AT91 I2C driver is currently marked as "broken" due to hardware
issues.  This patch enables AT91-based platforms to also use the
bitbanged GPIO for I2C.

This updates platform setup logic (setting up an i2c-gpio device
using the same pins as the i2c-at91 device, unless only the BROKEN
driver is enabled).

Also make use of the new-style initialization of I2C devices using
i2c_register_board_info().

Subject: [ARM] 4648/1: i.MX/MX1 ensure more complete AITC initialization

The AITC code did not allow to start kernel, if bootloader
manipulates with interrupt level mask. The change ensures,
that NIMASK is initialized into correct state and that
interrupts enable registers are cleared.

Subject: [ARM] 4659/1: remove possibilities for spurious false negative with
 __kuser_cmpxchg

The ARM __kuser_cmpxchg routine is meant to implement an atomic cmpxchg
in user space.  It however can produce spurious false negative if a
processor exception occurs in the middle of the operation.  Normally
this is not a problem since cmpxchg is typically called in a loop until
it succeeds to implement an atomic increment for example.

Some use cases which don't involve a loop require that the operation be
100% reliable though.  This patch changes the implementation so to
reattempt the operation after an exception has occurred in the critical
section rather than abort it.

Here's a simple program to test the fix (don't use CONFIG_NO_HZ in your
kernel as this depends on a sufficiently high interrupt rate):

	#include <stdio.h>

	typedef int (__kernel_cmpxchg_t)(int oldval, int newval, int *ptr);
	#define __kernel_cmpxchg (*(__kernel_cmpxchg_t *)0xffff0fc0)

	int main()
	{
		int i, x = 0;
		for (i = 0; i < 100000000; i++) {
			int v = x;
			if (__kernel_cmpxchg(v, v+1, &x))
				printf("failed at %d: %d vs %d\n", i, v, x);
		}
		printf("done with %d vs %d\n", i, x);
		return 0;
	}

Subject: [ARM] 4674/1: pxa: increase LCD PCLK drive strength to fast 2mA for
 PXA300/PXA310

Some platforms (e.g. Littleton) requires LCD PCLK drive strength to be
higher than default to cope with the fast PCLK frequency.
