From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: seccomp: allow COMPAT sigreturn overrides
Most architectures don't need to do much special for the strict-mode
seccomp syscall entries. Remove the redundant headers and reduce the
others.
This patch (of 8):
Some architectures may need to override the compat sigreturn definition,
as is already possible in the non-compat case.
