[MIPS] unexport copy_from_user_page()

2008-04-28T16:14:30Z

No users for the copy_from_user_page() routine exist outside of the core kernel code. Therefore, EXPORT_SYMBOL(copy_from_user_page) is useless, and this patch removes it. Signed-off-by: Dmitri Vorobiev Signed-off-by: Ralf Baechle

[MIPS] unexport copy_to_user_page()

2008-04-28T16:14:30Z

The copy_to_user_page() function is called only in the core kernel code. Therefore, there is no need to export it. This patch removes EXPORT_SYMBOL(copy_to_user_page). Signed-off-by: Dmitri Vorobiev Signed-off-by: Ralf Baechle

[MIPS] unexport copy_user_highpage()

2008-04-28T16:14:30Z

The copy_user_highpage() routine has no users outside of the core kernel code, so exporting this symbol is pointless. This patch removes EXPORT_SYMBOL(copy_user_highpage). Signed-off-by: Dmitri Vorobiev Signed-off-by: Ralf Baechle

[MIPS] All MIPS32 processors support64-bit physical addresses.

2008-04-28T16:14:25Z

Still, only the 4K may actually implement it. Signed-off-by: Chris Dearman Signed-off-by: Ralf Baechle

[MIPS] Fix buggy invocations of kmap_coherent()

2008-02-19T17:01:31Z

kmap_coherent will only work correctly if the page it is called on is not marked dirty. If it's dirty the kernel address of the page should be used instead of a temporary mapping. Signed-off-by: Ralf Baechle

[MIPS] 64-bit Sibyte kernels need DMA32.

2007-11-26T17:26:14Z

Sibyte SOCs only have 32-bit PCI. Due to the sparse use of the address space only the first 1GB of memory is mapped at physical addresses below 1GB. If a system has more than 1GB of memory 32-bit DMA will not be able to reach all of it. For now this patch is good enough to keep Sibyte users happy but it seems eventually something like swiotlb will be needed for Sibyte. Signed-off-by: Ralf Baechle

[MIPS] Convert reference to mem_map to pfn_to_page().

2007-11-15T23:21:48Z

This was crashing the combination of highmem and sparsemem. Signed-off-by: Ralf Baechle

[MIPS] Fix aliasing bug in copy_user_highpage, take 2.

2007-10-16T17:23:49Z

Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.
