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
(1) Masquerade clv
(2) Fix timeout
(3) Let mcexec thread with the same tid as McKernel thread migrating
to Linux handles the migration request
(4) Call create_tracer() before creating proxy related objects

While we are here, also optimize code a bit: perf_desc does not need
to be allocated for every cpu; and fix coding style.

Many ikc messages expecting a reply use wait_event_interruptible
incorrectly, freeing memory that could still be used on the other side.
This commit implements a generic ikc send and wait helper that helps
with memory management and ownership properly:
- if the message succeeds and a reply comes back normally, the memory
is freed by the caller as usual
- if the wait fails (signal before the reply comes or timeout) then the
memory is set as owner by ikc and will be free when the reply comes back
later
- if the reply never comes, the memory is freed at shutdown when
destroying ikc channels

<premap_size> of stack is pre-mapped on creating a process.
And its max size of stack is set to <max>.
This replaces MCKERNEL_RLIMIT_STACK=<premap_size>,<max>.
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header
