Subject: sh: Fixup kernel_execve() for syscall cleanups.
X-Git-Tag: firefly_0821_release~31885^2~5^2~9
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=79890c512444aa55a7a42ac5e7d29d7a4edba11b;p=firefly-linux-kernel-4.4.55.git

sh: Fixup kernel_execve() for syscall cleanups.

SH-2 and SH-2A need to use a different syscall base for the trapa
vector than the other parts, so fixup the logic in the kernel_execve()
case.
