This patch adds Samsung SMDKC210 board support file. The SoC
of SMDKC210, S5PC210(MCP) is one of package option of S5PV310.
And because composition of SMDKC210 and SMDKV310 differs, need
SMDKC210 with SMDKV310.

Add function definition for irq_chip.set_wake to enable GPIO to
wake-up the system.
This patch has been tested on a MX51 Babbage system that had suspend
code implemented. The set_wake implementation is necessary for a
GPIO to wake up a system from suspend.

Commit c074512 (imx-esdhc: update devices registration) renamed
MX35_INT_MMC_SDHC2 to MX35_INT_ESDHC2 which broke expansion of the
MXC_INT_MMC_SDHC2 macro.
As (the only user of MXC_INT_MMC_SDHC2) is only used on
mx31 use the MX31 prefixed symbol to define its resources. Moreover to
reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC
prefixed symbols are removed.

Use memblock information to setup lowmem mappings rather than the
membank array.
This allows platforms to manipulate the memblock information during
initialization to reserve (and remove) memory from the kernel's view
of memory - and thus allowing platforms to setup their own private
mappings for this memory without causing problems with multiple
aliasing mappings:
size = min(size, SZ_2M);
base = memblock_alloc(size, min(align, SZ_2M));
memblock_free(base, size);
memblock_remove(base, size);
This is needed because multiple mappings of regions with differing
attributes (sharability, type, cache) are not permitted with ARMv6
and above.

Commit 81d11955bf0 ("ARM: 6405/1: Handle __flush_icache_all for
CONFIG_SMP_ON_UP") added a new function to struct cpu_cache_fns:
flush_icache_all(). It also implemented this for v6 and v7 but not
for v5 and backwards. Without the function pointer in place, we
will be calling wrong cache functions.
For example with ep93xx we get following:

__dma_alloc() calls (inlined) __dma_alloc_buffer() which ends up
calling dmac_flush_range(). Now since the entries in the
arm920_cache_fns are shifted by one, we jump into address 0xee070f38
which is actually next instruction after the arm920_cache_fns
structure.
So implement flush_icache_all() for the rest of the supported CPUs
using a generic 'invalidate I cache' instruction.

When running following code in a machine which has VIVT caches and
USE_SPLIT_PTLOCKS is not defined:
fd = open("/etc/passwd", O_RDONLY);
addr = mmap(NULL, 4096, PROT_READ, MAP_SHARED, fd, 0);
addr2 = mmap(NULL, 4096, PROT_READ, MAP_SHARED, fd, 0);
v = *((int *)addr);
we will hang in spinlock recursion in the page fault handler:
BUG: spinlock recursion on CPU#0, mmap_test/717

This comes from the fact that when USE_SPLIT_PTLOCKS is not defined,
the only lock protecting the page tables is mm->page_table_lock
which is already locked before update_mmu_cache() is called.

| Commit e63075a3 removed the explicit MEMBLOCK_REAL_LIMIT #define
| and introduced the requirement that arch code calls
| memblock_set_current_limit to ensure that the __va macro can
| be used on physical addresses returned from memblock_alloc.
Unfortunately, ARM was missed out of this change. Fix this.

Commit 5085f3ff458521045f7e43da62b8c30ea7df2e82 added better support for
CONFIG_HOTPLUG_CPU by keeping proc_info around. However, depending on
the Kconfig options selected, this can make the booting fail mysteriously
early on.
Turns out a data abort can happen in __lookup_processor in ldmia r5 {r3, r4}.
When it happens the address loaded to r5 is not aligned. Fix the problem by
aligning proc_info.

After Santosh's fixup of the generic MT_MEMORY and
MT_MEMORY_NONCACHED I add this fix to the TCM memory types.
The main change is that the ITCM memory is L_PTE_WRITE and
DOMAIN_KERNEL which works just fine. The changed to the DTCM
is just cosmetic to fit with surrounding code.

Enable Westmere support on SGI UV. The UV initialization code is dependent on
the APICID bits. Westmere-EX uses different APIC bit mapping than Nehalem-EX.
This code reads the apic shift value from a UV MMR to do the proper bit
decoding to determint the pnode.

Currently, text_poke_smp() passes a NULL as the third argument to
__stop_machine(), which will only run stop_machine_text_poke()
on 1 cpu. Change NULL -> cpu_online_mask, as stop_machine_text_poke()
is intended to be run on all cpus.
I actually didn't notice any problems with stop_machine_text_poke()
only being called on 1 cpu, but found this via code inspection.

Commit 22d4cd4c4d ("Allocate irq stacks seperate from percpu
area") removed NUMA affinity of IRQ stacks as side-effect of
the fix.
Using alloc_pages_node() instead of __get_free_pages() is safe,
even if the target node has no available LOWMEM pages :
alloc_pages_node() fallbacks to another node.

Xen can reserve huge amounts of memory for pre-ballooning, but that
still shows as RAM in the e820 memory map. early_node_mem could not
find range because of start/end adjusting, and will go through the
fallback path. However, the fallback patch is still using
memblock_x86_find_range_node(), and it is partially top-down because
it go through active_range entries from low to high.
Let's use memblock_find_in_range instead memblock_x86_find_range_node.
So get real top down in fallback path.
We may still need to make memblock_x86_find_range_node to do overall
top_down work.

If the board has a debug uart the user is given a choice of which
uart to use. The user can also select NONE, which means not to use one.
In most of our header files when NONE is selected nothing is defined
for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile
failure in debug-macro.S which expect something to be defined there.
Example of the failure,
arch/arm/kernel/built-in.o: In function `hexbuf':
linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS'
linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE'
This fixes the compile failure by adding an ifdef to debug-macro.S
that removes all the debug uart code in the case of NONE.

Originally there was an ifdef case to handle when no debug uart
was selected. In commit 0ea1293009826da45e1019f45dfde1e557bb30df
that case was removed which causes the following build failure,
linux-2.6/arch/arm/kernel/debug.S: Assembler messages:
linux-2.6/arch/arm/kernel/debug.S:174: Error: bad instruction `addruart r1,r2'
linux-2.6/arch/arm/kernel/debug.S:176: Error: bad instruction `waituart r2,r3'

linux-2.6/arch/arm/kernel/debug.S:190: Error: bad instruction `addruart r1,r2'
This is a partial revert to add back the case which was removed with
two caveats. First the API for the addruart macro was updated, and
the new addruart case now return 0xfff00000 so that a know IO mapping
is created instead of a random one.
