c4b4b7222e arm64: ihk_mc_perfctr_start/stop: fix prototype that was changed in x86 
The functions now take a bitmask in argument since commit d7416c6f79
("perf_event: Specify counter by bit_mask on start/stop")...
Thanksfully the change also induced a type modification so it was easy
to notice.

(On the other hand I'm building with --disable-perf so why the hell is
that file compiled?!)

b93e14f695 arm64 signal.h: add valid_signal() function 
This function was added for x86 by commit 140f813d77 ("fix:
differences in behavior of sigaction between Linux and Mckernel")

The x86 and arm files are actually pretty close and could use
factoring...

bc0759e2dc arm64 arch-lock: add missing include for cpu_set 
Probably only needed for recent system, see ihk's 3271b5e6 ("fix
compilation with recent glibc (cpu_set define change)")

The root of the problem really is that we rely on system headers for
mckernel that ought to be independent...

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

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

3ce7763715 x86 mem init: do not map identity mapping 
init_normal_area was mapping identity lookups (phys = virt) from 0,
leading to many undetected null pointer dereferences in init_pt (but
not in new process page tables leading to odd behaviour)

This also makes the code use the set_pt_large_page() function, cleaning
it up a bit
