* sh: Split out PXSEG segmentation per-CPU family.Paul Mundt2008-01-27
| | | | | | | | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Force __access_ok() to obey address space limit.Paul Mundt2008-01-10
| | | | | | | | | | | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix argument page dcache flushing regression.Carmelo Amoroso2008-01-06
| | | | | | | | | | | | | 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.

| * sh: Kill off __{copy,clear}_user_page().Paul Mundt2007-11-06
| | | | | | | | | | | | | | | | | | Now that copy_to_user_page()/copy_from_user_page() are wired up, we can drop the old __copy_xxx() implementations. Now that the page colouring scheme has changed via kmap_coherent(), we can avoid the flush in these specific helpers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
