seq_file: Allocate memory using vmalloc when kmalloc failed

When dumpstate access /proc/xxx/binder, this binder include lots of info,
it will use seq_read in kernel, in this function, it will trigger
high order memory alloc, when read binder info or other large file,
this will cause memory presure when system don't have contious high order
memory, it will lead to high kswap workload to reclaim the page. so change
kmalloc to vmalloc, it can avoid contiously high order memory allocating.

msm: kgsl: GPU fault tolerance timer

GPU fault tolerance timer with a 50ms interval is introduced to detect
the condition where GPU is stalled, when GPU state is active we check
for GPU stall and if a stall is detected fault tolerance is triggered.
Using a timer is a better design because this removes dependency
on userspace to call waittimestamp.

msm: kgsl: Set proper pagetable address immediately after recovery

Update the MMU with proper pagetable address immediately after
recovery to avoid any translations with old pagetable.

msm: kgsl: Check long IB only for valid context

Do not check for long IB if the hang is detected in a NULL context,
hang in NULL context can happen when we are switching from NULL to
active context and hang is detected in commands that write an
active context to memstore, long IB in this scenario is not possible.

ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS

The {get,put}_user macros don't perform range checking on the provided
__user address when !CPU_HAS_DOMAINS.

This patch reworks the out-of-line assembly accessors to check the user
address against a specified limit, returning -EFAULT if is is out of
range.

[will: changed get_user register allocation to match put_user]
[rmk: fixed building on older ARM architectures]
