Thanks.

Am not terribly happy with the state of the gcov patches.  They STILL
leave thousands of dead symlinks lying around after `make mrproper' and
generally seem to muck up the kbuild system a bit, although nothing
that a bit of Sam love wouldn't fix.

Plus it breaks the build on a few architectures (branch out of range,
mainly), but that's a fairly minor thing which could even be worked
around in Kconfig (disable the offending code if gcov is enabled)
