Subject: [PATCH] s390x: provide sigcontext struct definition
This structure was missed when creating the s390x port.
This is based on the report and patch from William Pitcock, but with a
modified structure defintion to more closely match the kernel's
definition.
---
The kernel headers do not use mcontext_t, but rather another structure
with the same memory layout. It's broken into a different set of
sub-structures, and some members have different names.
