Thanks.  FWIW, changes since the last posting:
	* untested conversion for cris added [me]
	* conversion for mips added [Ralf has done execve side, I've added
kernel_thread() one]
	* conversion for parisc added [aka "Al has generated broken patches,
jejb has tested and fixed that crap"]
	* arm64 conversion added [Catalin Marinas]

IOW, right now we have
	* alpha, arm, arm64, c6x, m68k, mips, parisc, powerpc, s390, sparc,
um, x86 - apparently over and done with (IOW, all old architectures except for
itanic are converted by now)
	* avr32, blackfin, hexagon, h8300, ia64, m32r, microblaze, openrisc,
score, sh, tile, unicore32, xtensa - need to be done
	* cris, frv, mn10300 - need to be tested (and very likely will need
fixing)
