Dominique MartinetandMasamichi Takagi 52cd57fed2 memory/x86_64: fix linux safe_kernel_map 
init_linux_kernel_mapping is called in setup_x86_phase1 way
before arguments are setup, but we can access kernel boot args
directly and use that, so ugly fix for now.

 - fix uname -r (single quote?!)
 - add compat for rhel8 (el kernel and version is 4.18)
 - also remove linux version check in mcreboot.sh, trust configure check

Masamichi TakagiandDominique Martinet 04c11f35e9 xpmem: Add xpmem_openat 
In arm64, glibc-open of /dev/xpmem is hooked in sys_openat. This
commit adds xpmem_openat which is called by sys_openat.
This commit silently applies copy_from_user fix to sys_open as well.

Masamichi TakagiandDominique Martinet 38e68f358a Add kernel argument to turn on/off time sharing 
Add "-T 0" to mcreboot.sh if you want to turn off time sharing.  When
it's turned off, McKernel doesn't activate interval timer when the
length of per-CPU run-queue is larger than one.

Dominique MartinetandMasamichi Takagi c3bfa3f6a9 move BUG_ON, panic and kprintf define to debug.h; add BUILD_BUG_ON 
these functions are more logical to keep together there as they depend
on each other.

Also add a comment about the __printf attribute, if we have a quiet
period it would be useful to enable and clear the thousands of
warnings...

Dominique MartinetandMasamichi Takagi 3e3ccf377c compiler.h: add READ_ONCE/WRITE_ONCE macro 
These macros are needed to make sure the compiler does not optimize away
atomic constructs such as "while (!READ_ONCE(foo))" loops that do not
modify foo within the loop

Also move the barrier() define where it belongs while we are here, it is
needed for READ_ONCE/WRITE_ONCE and including ihk/cpu.h here causes
include loops

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()

One CPU could be chosen by concurrent forks because CPU selection and
runq addition are not done atomicly. So this fix makes the two steps
atomic.
