2009-03-24m68knommu: fix 5249 ColdFire UART setupGreg Ungerer
The ICR registers of the 5249 ColdFire processor are 8bits, not 32bits. Fix the read/write of these register to be the correct size. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-03-24m68knommu: fix end of uart table markerGreg Ungerer
The UART platform data structure is missing an empty struct at the end (as the end of structure marker). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-03-24m68knommu: switch to using generic_handle_irq()Greg Ungerer
Switch to using generic_handle_irq() instead of the deprecated __do_IRQ(). Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2009-03-24m68k: use the mmu pci.h for m68knommu as wellGreg Ungerer

2009-03-24m68knommu: add a local dma_sync_single_for_cpu() functionGreg Ungerer
The onboard ethernet of many ColdFire parts uses DMA. The driver is being cleaned up to use the correct DMA handling functions, and m68knommuy currently does not implement dma_sync_single_for_cpu(). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-03-24m68knommu: mark all RAM as ZONE_DMAGreg Ungerer
There is no reason not to put all RAM in ZONE_DMA for these simple m68k varients (same as the standard MMU m68k code does). With this in place the usual dma_alloc_coherent() work as expected. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2009-03-18sparc64: Fix crash with /proc/iomemMikulas Patocka
When you compile kernel on Sparc64 with heap memory checking and type "cat /proc/iomem", you get a crash, because pointers in struct resource are uninitialized. Most code fills struct resource with zeros, so I assume that it is responsibility of the caller of request_resource to initialized it, not the responsibility of request_resource functuion. After 2.6.29 is out, there could be a check for uninitialized fields added to request_resource to avoid crashes like this. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: David S.

2009-03-18[S390] make page table upgrade work againMartin Schwidefsky
After TASK_SIZE now gives the current size of the address space the upgrade of a 64 bit process from 3 to 4 levels of page table needs to use the arch_mmap_check hook to catch large mmap lengths. The get_unmapped_area* functions need to check for -ENOMEM from the arch_get_unmapped_area*, upgrade the page table and retry. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-03-18[S390] make page table walking more robustMartin Schwidefsky
Make page table walking on s390 more robust. The current code requires that the pgd/pud/pmd/pte loop is only done for address ranges that are below the end address of the last vma of the address space. But this is not always true, e.g. the generic page table walker does not guarantee this. Change TASK_SIZE/TASK_SIZE_OF to reflect the current size of the address space. This makes the generic page table walker happy but it breaks the upgrade of a 3 level page table to a 4 level page table. To make the upgrade work again another fix is required. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-03-18[S390] Dont check for pfn_valid() in uaccess_pt.cGerald Schaefer
pfn_valid() actually checks for a valid struct page and not for a valid pfn. Using xip mappings w/o struct pages, this will result in -EFAULT returned by the (page table walk) user copy functions, even though there is valid memory. Those user copy functions don't need a struct page, so this patch just removes the pfn_valid() check.
