5081dba658 Fix appletalk sysctl entry name
Gabriel C reported that modprobing appletalk on current git gives a
warning in dmesg :

   "sysctl table check failed: /net/appletalk .3.7 procname does not match binary path procname"

Oops.  My apologies it appears I made a mistake when creating my table
to check up on sysctl values.

8a53514043 SELinux: always check SIGCHLD in selinux_task_wait
When checking if we can wait on a child we were looking at
p->exit_signal and trying to make the decision based on if the signal
would eventually be allowed.  One big flaw is that p->exit_signal is -1
for NPTL threads and so aignal_to_av was not actually checking SIGCHLD
which is what would have been sent.  Even is exit_signal was set to
something strange it wouldn't change the fact that the child was there
and needed to be waited on.  This patch just assumes wait is based on
SIGCHLD.  Specific permission checks are made when the child actually
attempts to send a signal.

This resolves the problem of things like using GDB on confined domains
such as in RH BZ 232371.  The confined domain did not have permission to
send a generic signal (exit_signal == -1) back to the unconfined GDB.
With this patch the GDB wait works and since the actual signal sent is
allowed everything functions as it should.

d04533650f [MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.
The BCM148 has 4 cores but there are also just 4 generic timers available
so use the ZBbus cycle counter instead of it.  In addition the ZBbus
counter also offers a much higher resolution and 64-bit counting so I'm
considering a later complete conversion to it once I figure out if all
members of the Sibyte SOC family support it - the docs seem to agree but
the headers files seem to disagree ...

18dabf473e Change table chaining layout
Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:

- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
  at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
  with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
  NULL when passed such an entry.

It's thus important that sg table users use the proper accessors to get
and set the page member.

2596110a39 exportfs: add new methods
Add the guts for the new filesystem API to exportfs.

There's now a fh_to_dentry method that returns a dentry for the object looked
for given a filehandle fragment, and a fh_to_parent operation that returns the
dentry for the encoded parent directory in case the file handle contains it.

There are default implementations for these methods that only take a callback
for an nfs-enhanced iget variant and implement the rest of the semantics.

6e91ea2bb0 exportfs: add fid type
This patchset is a medium scale rewrite of the export operations interface.
The goal is to make the interface less complex, and easier to understand from
the filesystem side, aswell as preparing generic support for exporting of
64bit inode numbers.

This touches all nfs exporting filesystems, and I've done testing on all of
the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs)

This patch:

Add a structured fid type so that we don't have to pass an array of u32 values
around everywhere.  It's a union of possible layouts.

As a start there's only the u32 array and the traditional 32bit inode format,
but there will be more in one of my next patchset when I start to document the
various filehandle formats we have in lowlevel filesystems better.

Also add an enum that gives the various filehandle types human- readable
names.

Note: Some people might think the struct containing an anonymous union is
ugly, but I didn't want to pass around a raw union type.

00bf4098be kexec: add BSS to resource tree
Add the BSS to the resource tree just as kernel text and kernel data are in
the resource tree.  The main reason behind this is to avoid crashkernel
reservation in that area.

While it's not strictly necessary to have the BSS in the resource tree (the
actual collision detection is done in the reserve_bootmem() function before),
the usage of the BSS resource should be presented to the user in /proc/iomem
just as Kernel data and Kernel code.

Note: The patch currently is only implemented for x86 and ia64 (because
efi_initialize_iomem_resources() has the same signature on i386 and ia64).

c03ab37cbe intel-iommu sg chaining support
x86_64 defines ARCH_HAS_SG_CHAIN. So if IOMMU implementations don't
support sg chaining, we will get data corruption.

358dd8ac53 intel-iommu: fix for IOMMU early crash
pci_dev's->sysdata is highly overloaded and currently IOMMU is broken due
to IOMMU code depending on this field.

This patch introduces new field in pci_dev's dev.archdata struct to hold
IOMMU specific per device IOMMU private data.
