This series of patches brings in 32-bit arm support for bsd-user. It implements
all the bits needed to do image activation, signal handling, stack management
and threading. This allows us to get to the "Hello World" level and also to
satisfy all linking requirements. I've sliced up the current bsd-user fork
versions of all this code into what I hope are right-sized reviewable chunks.
make checkpatch has a couple of complaints about the comments for the signal
trampoline:
WARNING: Block comments use a leading /* on a separate line
+ /* 8 */ sys_sigreturn,
WARNING: Block comments use a leading /* on a separate line
+ /* 9 */ sys_exit
that I think should be ignored.
