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... [v2] fixed indentation stoopidity (Sergei Shtylyov) use AUDIT_ARCH_SH instead of EM_SH Based-on-patch-by: Richard Briggs <rgb@redhat.com> Signed-off-by: Eric Paris <eparis@redhat.com> Cc: linux-sh@vger.kernel.org
