Hannes Weisbach 4f2c1e07c1 Add ARCH variable to Makefiles 
In some Makefiles the ARCH variable was not set, although it was used.
In executer/user/Makefile.in it was used before it was set.

Dominique Martinet b894619d1b Speed up parallel builds 
- make should be $(MAKE)
 - add + in front of rules spawning long-lasted make process in a
subshell. (This would not be needed with $(MAKE) -C .. target, but our
makefiles do not handle that because they use $(PWD))
 - split the main 'all' rule as all 4 targets are independant
 - fix dependencies where appropriate for parallelism

Extra, not speed-related changes:
 - remove some double-colon for targets as they do not need it

This cuts build time from 5s to 1.5s on a laptop with -j4, and more
importantly from 85s to 35s on a KNL node.
As a bonus, the fixed dependencies removes the need to clean before
rebuilding all the time. Probably.

Dominique Martinet d213efac79 mcctrl/sysfs: add parenthesis around SYSFS_UNLINK_KEEP_ANCESTOR check 
! has more priority than &, so !flags & SYSFS_UNLINK_KEEP_ANCESTOR is
not very likely. Change to !(flags & SYSFS_UNLINK_KEEP_ANCESTOR)

Masamichi Takagi be4d84c0c1 mcexec: Add --stack-premap=<premap_size>[,<max>] 
<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>.

Masamichi Takagi 38961fca78 Revert "do_fork(): RLIMIT_NPROC check" 
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.
