More patches for ARC from Noriyuki Soda:
...
* commit isapnpvar.h changes required for ARC to support plain isa.
* fixup mistake over mips/include/cpuregs.h.
* mips/mips_machdep.c:
set L2 cache-size for arc, cleanup use of L2cache present
vs L2 cache-size variables. check for no L2 cache on kernels
configured to require one. misc cleanups.
* mips/mpis/trap.c: more locore stack-traceback label cleanup.
XXX Locore callbacks for mips3, mips4, r4600 cacheflush need more work.

hack here, as a result. This means that BSD programs can no longer be

Note that trap #1 is compat_13_sigreturn, and give trap #3 to syscalls
...
which require special handling, e.g. sigreturn on m68k.
This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.
