Pull sparc fixes from David Miller:
"Two small fixes for Sparc, nobody uses sparc, so these are low risk :-)
1) Piggyback is too picky about the symbol types that _start and _end
have in the final kernel image, and it thus breaks with newer
binutils. Future proof by getting rid of the symbol type checks.
2) exit_group() should kill register windows on sparc64 the same way
we do for plain exit(). Thanks to Al Viro for spotting this."

sparc: Fix piggyback with newer binutils.
sparc64: exit_group should kill register windows just like plain exit.
