userspace note handlers, like any function, expect ther
first argument in R0 register on arm.

procctl() is always called with up and it would not
work correctly if passed a different process, so
remove the Proc* argument and use up directly.

this change is in preparation for amd64. the systab calling
convention was also changed to return uintptr (as segattach
returns a pointer) and the arguments are now passed as
va_list which handles amd64 arguments properly (all arguments
are passed in 64bit quantities on the stack, tho the upper
part will not be initialized when the element is smaller
than 8 bytes).
this is partial. xalloc needs to be converted in the future.

pprint() might block or even (maliciously) call into
devproc write which will corrupt the qlock chain on attempt
to qlock up->debug again.

this simplifies the arm ports and keeps all the stuff in one place
instead of spreading it thru notify(), trap() and syscall() functions
and prevents useless fp state copying for kernel procs.
also make sure to save fp in notify while still splhi().
