Allow the timer register to be determined dynamically instead of at
compile time.  Use common virtual addresses for the registers across
all MSM chips, and select the register mappings based on the detected
CPU.

Create runtime queries to distinguish the various MSM targets.
Although these would probably be better named soc_is..., use
cpu_is... to match convention in the rest of the kernel.

Hard code the tests based on config options for now.  When runtime
device detection is implemented, these can be made dynamic.

When DEBUG_LL is not set, we don't want __error_a re-entering
__lookup_machine_type - we want it to go to the error function.  This
used to be the case before we reorganized the layout for hotplug cpu,
as we used to fall through to __error.  With the changed layout, we
need an explicit branch here instead.

Drive strength for PXA910 is a 2 bit value but because of the mapping in
plat-pxa/mfp.h needs to be shifted up one bit to handle real
location in mfp registers.  (MMP2 and PXA910 drive strength start
at bit 11 while PXA168 starts at bit 10).

Values 0, 1, 2, and 3 effectively need to be
0, 2, 4, and 6 to fit into register.  8 does not work.

Rabin Vincent reports:
| On SMP, this BUG() in save_stack_trace_tsk() can be easily triggered
| from user space by reading /proc/$PID/stack, where $PID is any pid but
| the current process:
|
|	if (tsk != current) {
| #ifdef CONFIG_SMP
|		/*
|		 * What guarantees do we have here that 'tsk'
|		 * is not running on another CPU?
|		 */
|		BUG();
| #else

Fix this by replacing the BUG() with an entry to terminate the stack
trace, returning an empty trace - I'd rather not expose the dwarf
unwinder to a volatile stack of a running thread.

Do not use memory bank info to request the "system ram" resources as
they do not track holes created by memblock_remove inside
machine's reserve callback. If the removed memory is passed as
platform_device's ioresource, then drivers that call
request_mem_region would fail due to a conflict with the incorrectly
configured system ram resource.

Instead, iterate through the regions of memblock.memory and add
those as "System RAM" resources.

pte alloc routines must wait for split_huge_page if the pmd is not present
and not null (i.e.  pmd_trans_splitting).  The additional branches are
optimized away at compile time by pmd_trans_splitting if the config option
is off.  However we must pass the vma down in order to know the anon_vma
lock to wait for.

Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for
module_init().  Much of the code is duplicated and can be generalized in a
globally accessible function, __vmalloc_node_range().

__vmalloc_node() now calls into __vmalloc_node_range() with a range of
[VMALLOC_START, VMALLOC_END) for functionally equivalent behavior.

Each architecture may then use __vmalloc_node_range() directly to remove
the duplication of code.
