sh: Initial vsyscall page support.
This implements initial support for the vsyscall page on SH. At the moment we leave it configurable due to having nommu to support from the same code base. We hook it up for the signal trampoline return at present, with more to be added later, once uClibc catches up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
