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: NPaul Mundt <lethal@linux-sh.org>

flush_cache_mm() wraps in to flush_cache_all(), which is rather excessive given that the number of PTEs within the specified context are generally quite low. Optimize for walking the mm's VMA list and selectively flushing the VMA ranges from the dcache. Invalidate the icache only if a VMA sets VM_EXEC. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This enables support for 4K stacks on SH. Currently this depends on DEBUG_KERNEL, but likely all boards will switch to this as the default in the future. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Some more machvec overhauling and setup code cleanup. Kill off get_system_type() and platform_setup(), we can do these both through the machvec. While we're add it, kill off more useless mach.c's and drop some legacy cruft from setup.c. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

nommu needs to be able to shift PAGE_OFFSET, so we switch it to a non-user-visible CONFIG_PAGE_OFFSET and use that in the few places where it matters. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Inhibit mapping through page tables in __ioremap() for PCI memory apertures on SH7751 and SH7780-style PCI controllers, translation is not possible for these areas. For other users that map a small window in P1/P2 space, ioremap() traps that already, and should never make it to __ioremap(). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
