    Pb1200/DBAu1200: fix bad IDE resource size

    The header files for the Pb1200/DBAu1200 boards have wrong definition for the
    IDE interface's decoded range length -- it should be 512 bytes according to
    what the IDE driver does.  In addition, the IDE platform device claims 1 byte
    too many for its memory resource -- fix the platform code and the IDE driver
    in accordance.

    Au1200: IDE driver build fix

    The driver fails to compile with CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA enabled:
    
    drivers/ide/mips/au1xxx-ide.c: In function `auide_build_dmatable':

    drivers/ide/mips/au1xxx-ide.c:275: warning: assignment makes pointer from
    integer without a cast
    
    Fix this by including <linux/scatterlist.h>. While at it, remove the #include's
    without which the driver happily builds.

    Au1200: kill IDE driver function prototypes

    Fix these warnings emitted when compiling drivers/ide/mips/au1xxx-ide.c:
    
    include/asm/mach-au1x00/au1xxx_ide.h:137: warning: 'auide_tune_drive' declared

    include/asm/mach-au1x00/au1xxx_ide.h:138: warning: 'auide_tune_chipset' declared
     `static' but never defined
    
    by wiping out the whole "function prototyping" section from the header file
    <asm-mips/mach-au1x00/au1xxx_ide.h> as it mostly declared functions that are
    already dead in the IDE driver; move the only useful prototype into the driver.

    USB: remove broken usb-serial num_endpoints check

    The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
    code are just wrong, there are too many different devices out there with
    different numbers of endpoints.  We need to just be sticking with the
    device ids instead of trying to catch this kind of thing.  It broke too
    many different devices.
    
    This fixes a large number of usb-serial devices to get them working
    properly again.

    acpi: unneccessary to scan the PCI bus already scanned

    http://bugzilla.kernel.org/show_bug.cgi?id=10124
    
    this change:
    
          commit 08f1c19
          Author: Muli Ben-Yehuda <muli@il.ibm.com>
          Date:   Sun Jul 22 00:23:39 2007 +0300
    
             x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
    
             This patch introduces struct pci_sysdata to x86 and x86-64, and
             converts the existing two users (NUMA, Calgary) to use it.
    
             This lays the groundwork for having other users of sysdata, such as
             the PCI domains work.
    
             The Calgary bits are tested, the NUMA bits just look ok.
    
    replaces pcibios_scan_root by pci_scan_bus_parented...
    
    but in pcibios_scan_root we have a check about scanned busses.

    vfs: fix possible deadlock in ext2, ext3, ext4 when using xattrs

    mb_cache_entry_alloc() was allocating cache entries with GFP_KERNEL.  But
    filesystems are calling this function while holding xattr_sem so possible
    recursion into the fs violates locking ordering of xattr_sem and transaction
    start / i_mutex for ext2-4.  Change mb_cache_entry_alloc() so that filesystems
    can specify desired gfp mask and use GFP_NOFS from all of them.

    Documentation: correct overcommit caveat in hugetlbpage.txt

    As shown by Gurudas Pai recently, we can put hugepages into the surplus
    state (by echo 0 > /proc/sys/vm/nr_hugepages), even when
    /proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to
    allow the original goal (shrink the static pool to 0) to succeed (we are
    converting hugepages to surplus because they are in use). However, the
    documentation does not accurately reflect this case. Update it.

    uml: compile error fix

    This patch fixes this error:
    
    In file included from /home/wangcong/projects/linux-2.6/arch/um/kernel/smp.c:9:
    include2/asm/tlb.h: In function `tlb_remove_page':
    include2/asm/tlb.h:101: error: implicit declaration of function `page_cache_release'
    
    And since including <linux/pagemap.h> in <linux/swap.h> will break sparc,
    we add this #include in uml's own header.

    It's reproducable in a x86_64 box, but doesn't happen in x86_32.
    
    This is because tsk->sighand is not guarded by RCU, so we have to
    hold tasklist_lock, just as what out_of_memory() does.

    serial: fix platform driver hotplug/coldplug

    Since 43cc71e, the platform modalias is
    prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable serial
    platform drivers, to re-enable auto loading.
    
    NOTE that Kconfig for some of these drivers doesn't allow modular builds, and
    thus doesn't match the driver source's unload support.  Presumably their
    unload code is buggy and/or weakly tested...

    rtc: fix the error in the function of cmos_set_alarm

    There is a bug in the function of cmos_set_alarm.  RTC alarm time for October
    can't be set correctly.
    
    For October: 0x0A will be written into the RTC region (MONTH_ALARM) in current
    kernel.  But in fact 0x10 should be written.  Wildcards are also not handled
    correctly.
