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

2bc4d06a48 Add empty definition of visit_pte_range_safe()
This is for linking only. visit_pte_range_safe() is required only
for memdump, as far as i can tell. Since memdump is disabled anyway
I think it's ok to leave this function empty for now.

4d4279121b process/vm; replace vm_range list by a rbtree
This replaces the chained list used to keep track of all memory ranges
of a process by a standard rbtree (no need of interval tree here
because there is no overlap)

Accesses that were done directly through vm_range_list before were
replaced by lookup_process_memory_range, even full list scan (e.g.
coredump).
The full scans will thus be less efficient because calls to rb_next()
will not be inlined, but these are rarer calls that can probably afford
this compared to code simplicity.

The only reference to the actual backing structure left outside of
process.c is a call to rb_erase in xpmem_free_process_memory_range.

v2: fix lookup_process_memory_range with small start address

v3: make vm_range_insert error out properly

Panic does not lead to easy debug, all error paths
are handled to just return someting on error

v4: fix lookup_process_memory_range (again)

That optimistically going left was a more serious bug than just
last iteration, we could just pass by a match and continue down
the tree if the match was not a leaf.

v5: some users actually needed leftmost match, so restore behavior
without the breakage (hopefully)
