Paul, I get:
arch/ppc64/include/asm/elf.h:190:8: warning: memset with byte count of -160
when checking ppc64 with sparse.
It looks like it's even correct. I think elf_gregset_t gets set to
elf_gregset_t32, which is why "struct pt_regs" is so much bigger than
elf_gregset_t.
Maybe it's a sparse bug. And maybe it isn't.

No it isn't, it's our bug. Stephen Rothwell and Michael Ellerman found it a day or two ago and there is a fix in the powerpc-merge tree already. If you do a pull from the powerpc-merge tree at git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc-merge.git (once it's mirrored, or the equivalent from master.kernel.org) you'll get the fix along with some more merging and some ppc patches. Diffstat and shortlog follow.
