Subject: [SPARC64]: Fix put_user() calls in binfmt_aout32.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8cc8c28a9acdceda0e60519167a052cc3408c5c3;p=linux-beck.git

[SPARC64]: Fix put_user() calls in binfmt_aout32.c

argv and envp are pointers to u32's in userspace, so don't
try to put_user() a NULL to them.

Aparently gcc-4.2.x now warns about this, and since we use
-Werror for arch/sparc64 code, this breaks the build.
