5eb691805f ACPICA: Fix for fault if Load() fails
Fixed a problem with the Load operator when loading a table from
a buffer object. The input buffer was prematurely zeroed and/or
deleted.

53cf174409 ACPICA: Fix for Alias operator to see target child objects
Fixed a problem with the Alias operator when the target of the
alias is a named ASL operator that opens a new scope -- Scope,
Device, PowerResource, Processor, and ThermalZone. In these cases,
any children of the original operator could not be accessed via
the alias, potentially causing unexpected AE_NOT_FOUND exceptions.

3e08e2d2d6 ACPICA: New interfaces for table event handlers
Designed and implemented new external interfaces to install and
remove handlers for ACPI table-related events. Current events that
are defined are LOAD and UNLOAD. These interfaces allow the host to
track ACPI tables as they are dynamically loaded and unloaded. See
AcpiInstallTableHandler and AcpiRemoveTableHandler.

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.

different numbers of endpoints.  We need to just be sticking with the

many different devices.

This fixes a large number of usb-serial devices to get them working

b87e81e5c6 acpi: unneccessary to scan the PCI bus already scanned

      commit 08f1c192c3
      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.

335e92e8a5 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.

423bec4307 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.

91446b064c add "Isolate" migratetype name to /proc/pagetypeinfo
In a5d76b54a3 (memory unplug: page isolation by
KAMEZAWA Hiroyuki), "isolate" migratetype added.  but unfortunately, it
doesn't treat /proc/pagetypeinfo display logic.

this patch add "Isolate" to pagetype name field.

b82d4043b3 Fix typos in Documentation/filesystems/seq_file.txt
A couple of typos crept into the newly added document about the seq_file
interface.  This patch corrects those typos and simultaneously deletes
unnecessary trailing spaces.
