sh: Force __access_ok() to obey address space limit.

2008-01-11T04:18:16Z

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

sh: Fix argument page dcache flushing regression.

2008-01-07T04:50:18Z

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.

Merge branch 'page_colouring_despair'

2007-11-08T08:01:42Z

sh: Add a dummy vga.h.

2007-11-07T11:19:30Z

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

sh: Fix up PAGE_KERNEL_PCC() for nommu.

2007-11-07T02:40:24Z

PAGE_KERNEL_PCC() takes two arguments, which weren't reflected in the nommu case. Fix it up. Signed-off-by: Paul Mundt

sh: Kill off __{copy,clear}_user_page().

2007-11-07T02:14:12Z

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

sh: Optimized copy_{to,from}_user_page() for SH-4.

2007-11-07T02:14:12Z

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

sh: Wire up clear_user_highpage().

2007-11-07T02:14:12Z

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
