From 37d181bbfe387346b00bd722acfdf93685ac73b3 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 11 Mar 2014 13:41:04 -0400 Subject: SH: define syscall_get_arch() for superh This patch defines syscall_get_arch() for the superh platform. It does so in both syscall_32.h and syscall_64.h. I'm not certain if the implementation in syscall_64.h couldn't just be used in syscall.h as I can't really track the setting of CONFIG_64BIT... This way is safe, but we might be able to combine these if a superh person were able to review...
