Re: "elf core dump: fix get_user use" breaks mips compilation

[Roland McGrath]

That is either a compiler problem or a problem with how the asm magic used
inside get_user() informs the compiler.  The dynamics of the code are not
actually much different than before the change.  

I imagine this would work around it:

--- a/fs/binfmt_elf.c
+++ b/fs/binfmt_elf.c
