2008-01-28sh: Split out cache status bits per-CPU family.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Split out PXSEG segmentation per-CPU family.Paul Mundt
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>
2008-01-11sh: Force __access_ok() to obey address space limit.Paul Mundt
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>
2008-01-07sh: Fix argument page dcache flushing regression.Carmelo Amoroso
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.

2007-11-08Merge branch 'page_colouring_despair'Paul Mundt
2007-11-07sh: Add a dummy vga.h.Paul Mundt
We have nothing to do here, but there are continually drivers that fail to build without it. Stub it in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix up PAGE_KERNEL_PCC() for nommu.Paul Mundt
PAGE_KERNEL_PCC() takes two arguments, which weren't reflected in the nommu case. Fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off __{copy,clear}_user_page().Paul Mundt
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>
2007-11-07sh: Optimized copy_{to,from}_user_page() for SH-4.Paul Mundt
This moves copy_{to,from}_user_page() out-of-line on SH-4 and converts for the kmap_coherent() API. Based on the MIPS implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Wire up clear_user_highpage().Paul Mundt
With the kmap_coherent() API in place, this is trivial to implement, and lets us avoid the cache flush in certain cases. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
