9ec0aeeab5 debug.h: merge both instances into ihk/debug.h 
We do not need two debug.h files.

Take Fujitsu's STATIC_ASSERT over BUILD_BUG_ON because it is more used

21cf953a03 x86: disable zero mapping and add a boot pt for ap trampoline 
the application processor trampoline needs the trampoline physical
address to be mapped for the few instructions between loading the
page table and jumping to normal memory area; setup a new pt for them.

Also make it use its stack where it needs to be directly.

With that, x86 can finally remove the 0 page from its init mapping

fe08ac4a67 arm: turn off cpu on panic 
Since interrupts are disabled on panic, linux cannot reset a
panic'd core when NMI are disabled (for e.g. mcreboot/mcstop)

Just always offline it, so linux can get it back

516ab87ab9 Copyrights: fujitsu 2018 bump 
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

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
