From 561c2bccc7c5cf3d42f38f1f4d61c7b609d4631e Mon Sep 17 00:00:00 2001 From: Hideo Saito Date: Thu, 15 May 2008 13:30:05 +0900 Subject: [PATCH] sh: Fix up thread info pointer in syscall_badsys resume path. Entry to resume_userspace expects r8 to contain current_thread_info, which happens in all paths except for syscall_badsys, where r8 was being inadvertently trampled. Reload it before the branch.
