Subject[PATCH 22/74] lto: Change kernel_execve to asmlinkage for all architectures
Date
From: Andi Kleen <ak@linux.intel.com>

The x86 kernel_execve has to be asmlinkage because it's called from
assembler code. To make it consistent I have to also change
the prototype in linux/syscalls.h

This in turn requires adding asmlinkage to all architectures.

Do this here in a tree sweep.
