The __cpu_{clear|copy}_user_page functions are not defined for the

If not MMU and not v6K, access to the TLS register has to be

The commit d815461c7a73903d0a926b3cace6f69e144c54a3 in linus tree
converts the rtc-rs5c372 driver to a "new style" i2c driver.
Like commit c00593f6f816e5cfa6d193a2561ca77541f71424, this patch
register the rtc i2c device for the em7210 board.

1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend
and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke
the corresponding _suspend functions, thus remove all those ugly
#ifdef .. #endif out of sleep.S
2. move the declarations of those suspend functions to pm.h
note: this is not a clean enough solution until all the pxa25x and
pxa27x specific part is further removed out of sleep.S, sleep.S is
supposed to contain generic code only

1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific
operations as follows:
struct pxa_cpu_pm_fns {
int save_size;
void (*save)(unsigned long *);
void (*restore)(unsigned long *);
int (*valid)(suspend_state_t state);
void (*enter)(suspend_state_t state);
}
2. processor specific registers saving and restoring are performed
by calling the corresponding (*save) and (*restore)
3. pxa_cpu_pm_fns->save_size should be initialized to the required
size for processor specific registers saving, the allocated
memory address will be passed to (*save) and (*restore)
memory allocation happens early in pxa_pm_init(), and save_size
should be assigned prior to this (which is usually true, since
pxa_pm_init() happens in device_initcall()
4. there're some redundancies for those SLEEP_SAVE_XXX and related
macros, will be fixed later, one way possible is for the system
devices to handle the specific registers saving and restoring

In order for this driver to be shared across the iop architectures the
iop3xx and iop13xx header files are modified to present a common interface
for the iop_wdt driver.
Details:
* iop13xx supports disabling the timer while iop3xx does not. This requires
a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to
preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code.
* The heartbeat interval is derived from the internal bus clock rate, so this
this patch also exports the tick rate to the iop_wdt driver.

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.
This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

per cpu data section contains two types of data. One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus. In the current kernel, these two sets are
not clearely separated out. This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.
One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end. Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.
This patch:
Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.

This patch completes Linus's wish that the fault return codes be made into
bit flags, which I agree makes everything nicer. This requires requires
all handle_mm_fault callers to be modified (possibly the modifications
should go further and do things like fault accounting in handle_mm_fault --
however that would be for another patch).

Remove the RTC management over a suspend/resume cycle. Firstly,
we may not be using the internal RTC for time keeping; some
platforms have an external RTC for this inspite of the PXA having
an internal RTC. Secondly, the RTC library code handles updating
system time on resume.

Since the number of dma channels varies between pxa25x and pxa27x, it
introduces some specific code in dma.c. This patch moves the specific
code to pxa25x.c and pxa27x.c and makes dma.c more generic.
1. add pxa_init_dma() for dma initialization, the number of channels
are passed in by the argument
2. add a "prio" field to the "struct pxa_dma_channel" for the channel
priority, and is initialized in pxa_init_dma()
3. use a general priority comparison with the channels "prio" field so
to remove the processor specific pxa_for_each_dma_prio macro, this
is not lightning fast as the original one, but it is acceptable as
it happens when requesting dma, which is usually not so performance
critical
