Re: [PATCH 1/4] 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... Signed-off-by: Eric Paris <eparis(a)redhat.com&gt; Cc: linux-sh(a)vger.kernel.org
