* microblaze: Fix sparse warning - consistent_alloc functionMichal Simek2011-03-091-1/+1
| | | | | | | | | | | | Warning in dma.c was caused by incorrect type in consistent_alloc function. Warning log: CHECK arch/microblaze/kernel/dma.c arch/microblaze/kernel/dma.c:53:26: warning: incorrect type in argument 1 (different base types) arch/microblaze/kernel/dma.c:53:26: expected int [signed] gfp arch/microblaze/kernel/dma.c:53:26: got restricted unsigned int [usertype] flag Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Fix pte_update functionMichal Simek2011-02-071-14/+13Star
| | | | | | | | Do not disable irq in asm but use irq macros. Systems with MSR=0 couldn't use pte_update function because msrclr was hardcoded. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Fix asm/pgtable.hMichal Simek2011-01-161-2/+4
| | | | | | | | | | | | | | | | | | Function ptep_test_and_clear_young have had wrong the first argument. It is also necessary to add __HAVE macros for ptep_test_and_clear_young and ptep_get_and_clear functions.

* mm: remove pte_*map_nested()Peter Zijlstra2010-10-271-5/+2Star
| | | | | | | | | | | | | | | | | | | | | | Since we no longer need to provide KM_type, the whole pte_*map_nested() API is now redundant, remove it.

* microblaze: Define VMALLOC_START/ENDMichal Simek2010-10-211-0/+7
| | | | | | | per cpu changes requires VMALLOC_START/END to be define even for noMMU systems. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Fix consistent codeMichal Simek2010-05-061-1/+1
| | | | | | | | | | | | This patch fix consistent code which had problems with consistent_free function. I am not sure if we need to call flush_tlb_all after it but it keeps tlbs synced. I added noMMU and MMU version together. Uncached shadow feature is not tested. Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: Enable PCI, missing filesMichal Simek2010-03-111-0/+15
| | | | | | | | | | | | | | There are two parts of changes. The first is just enable PCI in Makefiles and in Kconfig. The second is the rest of missing files. I didn't want to add it with previous patch because that patch is too big. Current Microblaze toolchain has problem with weak symbols that's why is necessary to apply this changes to be possible to compile pci support. Xilinx knows about this problem.

* microblaze: Add _PAGE_FILE macros to pgtable.hMichal Simek2009-07-271-3/+3
| | | | | | | | | We need to define _PAGE_FILE macro and change pte functions. Microblaze use the same MMU as PowerPC that's why we define _PAGE_FILE in the same style. This change fixed remap_file_pages01 LTP test. Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: add a dummy pgprot_noncachedArnd Bergmann2009-05-211-0/+2
| | | | | | | | | | Some device drivers call this, so add a macro that pretends to do this. Since there is no MMU support, it won't actually result in an uncached mapping, though. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
