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>
2007-11-07sh: Kill off the remaining ST40 cruft.Paul Mundt
The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.
