a563d780c1 munmap: fix deadlock with remote pagefault on vm range lock 
Add similar protection to clear_host_pte than to set_host_vma (see #986)

Also make the page fault handler only skip taking lock if the munmap
happened on the same cpu id

edd3ea0103 Revert "memory_range_lock: Enable interrupt when trylock fails" 
This reverts commit 0d3ef65092.

Reason for revert: This fix causes circular dependency with memory_range manipulation and TLB flush. See #1394.

ea7f517e3d arm64: ptrace: Fix overwriting 1st argument with return value 
Since arm64 shares the return value with the area of
the first argument, rewriting the return value before
the system call execution completes destroys the first argument.

Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

(1) Add --enable-uti option. The binary-patch library is

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()

0b0b7b03d7 Prevent one CPU from getting chosen by concurrent forks 
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.

3185334c1c debug messages: implement dynamic debug 
Heavily inspired off linux kernel's dynamic debug:
 * add a /sys/kernel/debug/dynamic_debug/control file
 (accessible from linux side in /sys/class/mcos/mcos0/sys/kernel/debug/dynamic_debug/control)
 * read from file to list debug statements (currently limited to 4k in size)
 * write to file with '[file foo ][func bar ][line [x][-[y]]] [+-]p' to change values

Side effects:
 * reindented all linker scripts, there is a new __verbose section
 * added string function strpbrk
