The pwm hardware only checks the compare register after a decrement,
so the pin never toggles if tcmp = tcnt.
This happens when a very low duty cycle is requested. Fix it by always
ensuring that tcmp < tcnt.

The value of armclk_mask needs to be inverted for use as a mask on
the register value when updating ARM_RATIO.
This is critical for cpufreq support, without it attempts to scale
the frequency of the core trash pretty much the entire clock tree.

If the requested clock is faster than the parent clock then the
parent clock is the closest we can get to the request so we need
to return that instead of the requested clock.

In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is
in the gpio banks range is reversed. Thus the function returns NULL for valid
pins and the gpio chip if its not valid.
As a result gpio states are not saved/restored properly during suspend/resume.

This issue is caused by using gpio pin without request. Add gpio_request()
into zylonite. To simplify the code, error checking is omitted since this

Update the NOR flash support for TS-7200.
The TS-7200 models all have 16-bit NOR flash. Update the platform
init to support this.
Remove the private TS72XX_NOR_* defines and use the common ep93xx
defines for the external chip select physical base address instead.
Move the NOR flash registration into a static __init function. When
the NAND flash support is updated this function will also be used
to register the NAND flash for the TS-7250 and TS-7260.

This patch for at_hdmac adds the slave transfers capability to the Atmel DMA
controller available on some AT91 SOCs. This allow peripheral to memory and
memory to peripheral transfers with hardware handshaking.
Slave structure for controller specific information is passed through channel
private data. This at_dma_slave structure is defined in at_hdmac.h header file
and relative hardware definition are moved to this file from at_hdmac_regs.h.
Doing this we allow the channel configuration from platform definition code.
This work is intensively based on dw_dmac and several slave implementations.

This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on
at91sam9rl chip. It will be used on other products in the future.
This first release covers only the memory-to-memory tranfer type. This is the
only tranfer type supported by this chip. On other products, it will be used
also for peripheral DMA transfer (slave API support to come).
I used dmatest client without problem in different configurations to test it.
Full documentation for this controller can be found in the SAM9RL datasheet:

mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.
Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.
The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

This makes the VIC resume from suspend flagged IRQ:s identical to
the flags indicating all possible interrupts. This is perhaps not
the optimal setting but setting it to 0 makes the system suspend
and never come back again (all IRQ sources masked off).

The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6
display controller on the first SPI interface, using GPIO57 as a chip-select
for it. S6E63D6 is initialised in the boot-loader, so we only have to take care
of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a
"pcm037_variant=" kernel command line parameter to specify at boot-time which
board the kernel is running on, default is "pcm970", specify "eet" for the EET
board.

As slab is available early now, use kzalloc() rather than
alloc_bootmem_low() in pxa_init_gpio_chip().
This removes the following boot time warning:

In commit f23d4911319fd, the pwr-i2c device name changed due to the
newly introduced device table. This patch fixes the clock so the
driver's probe will succeed again.

Pull the initial preempt_count value into a single
definition site.
Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.
The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.
