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.

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.

2009-03-18[S390] __div64_31 broken for CONFIG_MARCH_G5Martin Schwidefsky
The implementation of __div64_31 for G5 machines is broken. The comments in __div64_31 are correct, only the code does not do what the comments say. The part "If the remainder has overflown subtract base and increase the quotient" is only partially realized, the base is subtracted correctly but the quotient is only increased if the dividend had the last bit set. Using the correct instruction fixes the problem.
