In 4.10 with 5b56d49fc31d ("mm: add locked parameter to
get_user_pages_remote()")
In 4.9 with 9beae1ea8930 ("mm: replace get_user_pages_remote()
write/force parameters with gup_flags")

We had a deadlock between:
- free_process_memory_range (take lock) -> ihk_mc_pt_free_range ->
... -> remote_flush_tlb_array_cpumask -> "/* Wait for all cores */"
and
- obj_list_lookup() under fileobj_list_lock that disabled irqs
and thus never ack'd the remote flush
The rework is quite big but removes the need for the big lock,
although devobj and shmobj needed a new smaller lock to be
introduced - the new locks are used much more locally and
should not cause problems.
On the bright side, refcounting being moved to memobj level means
we could remove refcounting implemented separately in all object
types and simplifies code a bit.

Defining C structures for the following objects:
(1) Remote and local context
(2) Stack of system call arguments / return values
Change-Id: Iafbb6c795bd765e3c78c54a255d8a1e4d4536288
(1) Add --enable-uti option. The binary-patch library is
preloaded with this option.
(2) Binary-patching is done by syscall_intercept developed by Intel
This commit includes the following fixes:
(1) Fix do_exit() and terminate() handling
(2) Fix timing of killing mcexec threads when McKernel thread calls terminate()
Change-Id: Iad885e1e5540ed79f0808debd372463e3b8fecea
It is accompanied by the following fixes:
(1) Fix put ppd locations in mcexec_wait_syscall()
(2) Move put ptd to end of mcexec_terminate_thread_unsafe() and mcexec_ret_syscall()
(3) Add debug messages for ptd add/get/put
(4) Fix ptd-add/get/put matching in mcexec_wait_syscall()
* Skip put when woken-up from wait_event_interruptible() by signal
