Commit 'xfrm: Move IPsec replay detection functions to a separate file'
  (9fdc4883)
introduce repl field to struct xfrm_state, and only initialize it
under SA's netlink create path, the other path, such as pf_key,
ipcomp/ipcomp6 etc, the repl field remaining uninitialize. So if
the SA is created by pf_key, any input packet with SA's encryption
algorithm will cause panic.

    int xfrm_input()
    {
        ...
        x->repl->advance(x, seq);
        ...
    }

This patch fixed it by introduce new function __xfrm_init_state().

'buffer' string is copied from userspace.  It is not checked whether it is
zero terminated.  This may lead to overflow inside of simple_strtoul().
Changli Gao suggested to copy not more than user supplied 'size' bytes.

It was introduced before the git epoch.  Files "ipt_CLUSTERIP/*" are
root writable only by default, however, on some setups permissions might be
relaxed to e.g. network admin user.

commit f3c5c1bf (make ip_tables reentrant) introduced a race in
handling the stackptr restore, at the end of ipt_do_table()

We should do it before the call to xt_info_rdunlock_bh(), or we allow
cpu preemption and another cpu overwrites stackptr of original one.

A second fix is to change the underflow test to check the origptr value
instead of 0 to detect underflow, or else we allow a jump from different
hooks.

When the OF device driver bits were converted over to the platform
device infrastructure in commit 74888760
("dt/net: Eliminate users of of_platform_{,un}register_driver") we
inadvertantly created probing problems in the OF case.

The NIU driver creates a dummy platform device to represent the
board that contains one or more child NIU devices.  Unfortunately
we use the same name, "niu", as the OF device driver itself uses.

The result is that we try to probe the dummy "niu" parent device we
create, and since it has a NULL ofdevice pointer etc. everything
explodes:

include/linux/dw_spi.h only includes driver internal data.  It doesn't
expose a platform_data configuration structure or similar (at least
nothing in-tree).  This patch moves the header into drivers/spi so
that the scope is limited to only the dw_spi_*.c driver files

Currently, build on PPC dies with:
In file included from drivers/spi/dw_spi_mmio.c:16:
include/linux/spi/dw_spi.h:147: error: field ‘tx_sgl’ has incomplete type
include/linux/spi/dw_spi.h:149: error: field ‘rx_sgl’ has incomplete type

Add linux/scatterlist.h include to dw_spi.h, because we need to know
the contents of the structure.

While trying to track down some NFS problems with BTRFS, I kept noticing I was
getting -EACCESS for no apparent reason.  Eric Paris and printk() helped me
figure out that it was SELinux that was giving me grief, with the following
denial

type=AVC msg=audit(1290013638.413:95): avc:  denied  { 0x800000 } for  pid=1772
comm="nfsd" name="" dev=sda1 ino=256 scontext=system_u:system_r:kernel_t:s0
tcontext=system_u:object_r:unlabeled_t:s0 tclass=file

Turns out this is because in d_obtain_alias if we can't find an alias we create
one and do all the normal instantiation stuff, but we don't do the
security_d_instantiate.

Usually we are protected from getting a hashed dentry that hasn't yet run
security_d_instantiate() by the parent's i_mutex, but obviously this isn't an
option there, so in order to deal with the case that a second thread comes in
and finds our new dentry before we get to run security_d_instantiate(), we go
ahead and call it if we find a dentry already.  Eric assures me that this is ok
as the code checks to see if the dentry has been initialized already so calling
security_d_instantiate() against the same dentry multiple times is ok.  With
this patch I'm no longer getting errant -EACCESS values.

Make sure the 'match' variable always has a value.
