52afbbbc98 uti: Call into McKernel futex() 
(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

6df4bd8f8c Fix a few more warnings 
Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

aaa246f86f mcexec: change debug printf macros to be more tolerant to trivial format 
Enabling DEBUG fails to compile. It'd be easy to fix the dprintf to dprint
but this is just as generic and we can now use dprintf everywhere

This reverts commit 035e7913d8.
 2017-07-13 04:13:41 +09:00
Masamichi Takagi
035e7913d8 do_fork(): RLIMIT_NPROC check 
1. mcexec sets RLIMIT_NPROC to the number of mcexec threads.
2. do_fork() gets the current number of threads by calling rusage function.
3. do_fork() returns -EAGAIN when the limit is exceeded.
