5a668651bf sh: Split out PXSEG segmentation per-CPU family. 
The CPU family abstraction already exists, so move out the PXSEG
definition for each one. SH-2A already has this special cased,
and SH-5 will as well.

d7587b1445 sh: Force __access_ok() to obey address space limit. 
When the thread_info->addr_limit changes were introduced, __access_ok()
was missed in the conversion, allowing user processes to perform P1/P2
accesses under certain conditions.

This has already been corrected with the nommu refactoring in later
kernels.

844b43adba sh: Fix argument page dcache flushing regression. 
In the do_execve() path, argument page handling used to explicitly call
flush_dcache_page() for each page, this has since been reworked and
uses flush_kernel_dcache_page() instead, which is presently a nop.

Doing a simple modprobe/rmmod in a loop under busybox consistently
manages to crash without providing a sane flush_kernel_dcache_page()
implementation, so, plug in a simple implementation.
