msm: kgsl: Force the ME off before reading the microcode

On A3XX reading the microcode while the CP is running is dangerous
beyond words.  By setting the offset address for the read, we are
essentially changing the instruction pointer for the ME while it
is running causing opcode errors, gpu faults and/or system errors.

We do not want to stop the CP at the beginning of the snapshot
process beacuse doing so changes the RBBM status and the state of
the CP registers which may damage the debug effort.  But by the
time we get to the microcode read we no longer care about the state
of the registers so we can freely halt the ME just before starting
the read.

msm: kgsl: Increase the timeout value for fault detection

Increment the timeout value for detecting faults from 50ms to
200ms. The fault detection mechanism is a backup to hardware
fault detection. 50ms is small since it has been observed that
this mechanism triggers false positives with 50ms.

msm: kgsl: Don't hold the refernce to the process private in kgsl create context

There is a possible race condition for dev_priv where the kgsl_release
is called, while adreno_ft_detect has reference for the same context.
This change will avoid to use dev_priv in context destroy, which is
already freed in kgsl_release.

n_tty: Fix n_tty_write crash when echoing in raw mode

The tty atomic_write_lock does not provide an exclusion guarantee for
the tty driver if the termios settings are LECHO & !OPOST. And since
it is unexpected and not allowed to call TTY buffer helpers like
tty_insert_flip_string concurrently, this may lead to crashes when
concurrect writers call pty_write. In that case the following two
writers:
* the ECHOing from a workqueue and
* pty_write from the process
race and can overflow the corresponding TTY buffer like follows.

If we look into tty_insert_flip_string_fixed_flag, there is:
  int space = __tty_buffer_request_room(port, goal, flags);
  struct tty_buffer *tb = port->buf.tail;
  ...
  memcpy(char_buf_ptr(tb, tb->used), chars, space);
  ...
  tb->used += space;

so the race of the two can result in something like this:
          A                             B
   __tty_buffer_request_room
                                  __tty_buffer_request_room
   memcpy(buf(tb->used), ...)
   tb->used += space;
                                 memcpy(buf(tb->used), ...) ->BOOM

B's memcpy is past the tty_buffer due to the previous A's tb->used
increment.

Since the N_TTY line discipline input processing can output
concurrently with a tty write, obtain the N_TTY ldisc output_lock to
serialize echo output with normal tty writes. This ensures the tty
buffer helper tty_insert_flip_string is not called concurrently and
everything is fine.

Note that this is nicely reproducible by an ordinary user using
forkpty and some setup around that (raw termios + ECHO). And it is
present in kernels at least after commit
d945cb9cce20ac7143c2de8d88b187f62db99bdc (pty: Rework the pty layer to
use the normal buffering logic) in 2.6.31-rc3.

msm_bam_rmnet: Fix potential memory corruption

Usage of legacy string manipulation function sprintf could lead to
memory corruption as the number of bytes to be written to the
destination is not bounded. Replace sprintf with snprintf where the
number of bytes to be written is explicitly specified.
