Remove wrapper functions. This makes the allocation type explicit in
all callers; I used GPF_KERNEL where it seemed obvious, left it at
GFP_ATOMIC otherwise.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:
fs/9p: iattr_valid flags are kernel internal flags map them to 9p values.
fs/9p: We should not allocate a new inode when creating hardlines.
fs/9p: v9fs_stat2inode should update suid/sgid bits.
9p: Reduce object size with CONFIG_NET_9P_DEBUG
fs/9p: check schedule_timeout_interruptible return value
Fix up trivial conflicts in fs/9p/{vfs_inode.c,vfs_inode_dotl.c} due to
debug messages having changed to use p9_debug() on one hand, and the
changes for umode_t on the other.

The NFSv4 bitmap size is unbounded: a server can return an arbitrary
sized bitmap in an FATTR4_WORD0_ACL request. Replace using the
nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server
with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data
xdr length to the (cached) acl page data.
This is a general solution to commit e5012d1f "NFSv4.1: update
nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead
when getting ACLs.
Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr
was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

Commit 5b7c84066733c5dfb0e4016d939757b38de189e4 ('ipv4: correct IGMP
behavior on v3 query during v2-compatibility mode') added yet another
case for query parsing, which can result in max_delay = 0. Substitute
a value of 1, as in the usual v3 case.

dev_uc_sync() and dev_mc_sync() are acquiring netif_addr_lock for
destination device of synchronization. Since netif_addr_lock is
already held at the time for source device, this triggers lockdep
deadlock warning.
There's no way this deadlock can happen so use spin_lock_nested() to
silence the warning.

In 882716604ec "pktgen: fix multiple queue warning" we added special
logic to handle the case where ntxq is zero. It's not clear to me that
ntxq can actually be zero. But if it were then we would set
->queue_map_min and ->queue_map_max to USHRT_MAX when probably we want
to set them to zero?

Sockets can also be created through sock_clone. Because it copies
all data in the sock structure, it also copies the memcg-related pointer,
and all should be fine. However, since we now use reference counts in
socket creation, we are left with some sockets that have no reference
counts. It matters when we destroy them, since it leads to a mismatch.

percpu: Remove irqsafe_cpu_xxx variants
Fix up conflict in arch/x86/include/asm/percpu.h due to clash with
cebef5beed3d ("x86: Fix and improve percpu_cmpxchg{8,16}b_double()")
which edited the (now removed) irqsafe_cpu_cmpxchg*_double code.

We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state. That has no material change for x86
and s390 implementations of this_cpu operations. However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.
-tj: This is part of on-going percpu API cleanup. For detailed
discussion of the subject, please refer to the following thread.

These comments mention CONFIG options that do not exist: not as a symbol
in a Kconfig file (without the CONFIG_ prefix) and neither as a symbol
(with that prefix) in the code.
There's one reference to XSCALE_PMU_TIMER as a negative dependency.
But XSCALE_PMU_TIMER is never defined (CONFIG_XSCALE_PMU_TIMER is
also unused in the code). It shows up with type "unknown" if you search
for it in menuconfig. Apparently a negative dependency on an unknown
symbol is always true. That negative dependency can be removed too.

Allow the freezer to skip wait_on_bit_killable sleeps in the sunrpc
layer. This should allow suspend and hibernate events to proceed, even
when there are RPC's pending on the wire.
Also, wrap the TASK_KILLABLE sleeps in NFS layer in freezer_do_not_count
and freezer_count calls. This allows the freezer to skip tasks that are
sleeping while looping on EJUKEBOX or NFS4ERR_DELAY sorts of errors.

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else. Not to mention the removal of
boilerplate code from ->destroy_inode() instances...

This patch splits the red_parms structure into two components.
One holding the RED 'constant' parameters, and one containing the
variables.
This permits a size reduction of GRED qdisc, and is a preliminary step
to add an optional RED unit to SFQ.
SFQRED will have a single red_parms structure shared by all flows, and a
private red_vars per flow.

SFQ as implemented in Linux is very limited, with at most 127 flows
and limit of 127 packets. [ So if 127 flows are active, we have one
packet per flow ]
This patch brings to SFQ following features to cope with modern needs.
- Ability to specify a smaller per flow limit of inflight packets.
(default value being at 127 packets)
- Ability to have up to 65408 active flows (instead of 127)
- Ability to have head drops instead of tail drops
(to drop old packets from a flow)
Example of use : No more than 20 packets per flow, max 8000 flows, max
20000 packets in SFQ qdisc, hash table of 65536 slots.
tc qdisc add ... sfq \
flows 8000 \
depth 20 \
headdrop \
limit 20000 \
divisor 65536
Ram usage :
2 bytes per hash table entry (instead of previous 1 byte/entry)
32 bytes per flow on 64bit arches, instead of 384 for QFQ, so much
better cache hit ratio.

Not now, but it looks you are correct. q->qdisc is NULL until another
additional qdisc is attached (beside tfifo). See 50612537e9ab2969312.
The following patch should work.

defer calling the driver commands i.e. setup fragmentation
threshold, rts threshold and coverage class till drv_start
routine is called.

when we run high bandwidth UDP traffic and we trigger a scan, the scan
state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND
and SET_CHANNEL seems to be never called as 'tx_empty' is never true
while running UDP traffic. fix this by settting SET_CHANNEL state when
we get into RESUME state.

If the vif is stopped while it is offchannel (e.g. right
after p2p negotiation) the SDATA_STATE_OFFCHANNEL flag
is never get cleared, resulting in various bad effects
(e.g. GO can't start beaconing).
Fix it by clearing the SDATA_STATE_OFFCHANNEL flag
even if the vif is stopped.

Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:
o Frans Pop RIP 2010 [0]
- Frans Pop <elendil@planet.nl>
- Frans Pop <fjp@debian.org>
o Nokia RIP February, 11, 2011 [1], [2]
- ext-yuri.ershov@nokia.com
- kalle.valo@nokia.com
Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.
As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.
The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

Nokia hasn't gotten back to me in over 1 month for a relicense
change request. There are only a few changes that they contributed,
so just reverting their changes but replacing with another set.
This change replaces this commit:
commit 269ac5fd2d75b118d76a2291e28796527db2f3f8

cfg80211: indent regulatory messages with spaces
The regulatory messages in syslog look weird:
kernel: cfg80211: Regulatory domain: US
kernel: ^I(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
kernel: ^I(2402000 KHz - 2472000 KHz @ 40000 KHz), (600 mBi, 2700 mBm)
kernel: ^I(5170000 KHz - 5190000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5190000 KHz - 5210000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5210000 KHz - 5230000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5230000 KHz - 5330000 KHz @ 40000 KHz), (600 mBi, 2300 mBm)
kernel: ^I(5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 3000 mBm)
Indent them with four spaces instead of the tab character to get prettier
output.

In some cases there could be possible dereferencing freed pointer. The
update is intended to avoid this issue.
