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.

2009-03-18sh: add kexec jump supportMagnus Damm
Add kexec jump support to the SuperH architecture. Similar to the x86 implementation, with the following exceptions: - Instead of separating the assembly code flow into two parts for regular kexec and kexec jump we use a single code path. In the assembly snippet regular kexec is just kexec jump that never comes back. - Instead of using a swap page when moving data between pages the page copy assembly routine has been modified to exchange the data between the pages using registers. - We walk the page list twice in machine_kexec() to do and undo physical to virtual address conversion.

The "c-enter" USB to Toshiba 1.8" IDE enclosure needs special treatment to work flawlessly. This patch is absolutely trivial, as the integrated USB-IDE bridge is already identified to be an "unusual" device, only the bcdDevice is different (lower) to the bcdDeviceMin already included in the kernel. It is a Prolific 2507 bridge.

2009-03-17USB: EHCI: expedite unlinks when the root hub is suspendedAlan Stern
This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.

2009-03-17USB: EHCI: Fix isochronous URB leakKarsten Wiese
ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing isochronous URB's kref.counts incrementing once per usb_submit_urb() call. The culprit is *usb being set to NULL when usb_put_urb() is called after URB is given back. Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb() nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd. Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a stream finishes.
