This is the result of pulling on the thread started by Krzysztof Mazur's
original patch 'pppoatm: don't send frames to destroyed vcc'.
Various problems in the pppoatm and br2684 code are solved, some of which
were easily triggered and would panic the kernel.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The immediate use case for this is that it will allow us to ensure that a
pppoatm queue is woken after it has to drop a packet due to the sock being
locked.
Note that 'release_cb' is called when the socket is *unlocked*. This is
not to be confused with vcc_release() — which probably ought to be called
vcc_close().

commit 68835aba4d (net: optimize INET input path further)
moved some fields used for tcp/udp sockets lookup in the first cache
line of struct sock_common.
This patch moves inet_dport/inet_num as well, filling a 32bit hole
on 64 bit arches and reducing number of cache line misses in lookups.
Also change INET_MATCH()/INET_TW_MATCH() to perform the ports match
before addresses match, as this check is more discriminant.
Remove the hash check from MATCH() macros because we dont need to
re validate the hash value after taking a refcount on socket, and
use likely/unlikely compiler hints, as the sk_hash/hash check
makes the following conditional tests 100% predicted by cpu.
Introduce skc_addrpair/skc_portpair pair values to better
document the alignment requirements of the port/addr pairs
used in the various MATCH() macros, and remove some casts.
The namespace check can also be done at last.
This slightly improves TCP/UDP lookup times.
IP/TCP early demux needs inet->rx_dst_ifindex and
TCP needs inet->min_ttl, lets group them together in same cache line.
With help from Ben Hutchings & Joe Perches.
Idea of this patch came after Ling Ma proposal to move skc_hash
to the beginning of struct sock_common, and should allow him
to submit a final version of his patch. My tests show an improvement
doing so.

This series of improvements for 3.8/net-next contains four components:
* Support for modifying IPv6 headers
* Support for matching and setting skb->mark for better integration with
things like iptables
* Ability to recognize the EtherType for RARP packets
* Two small performance enhancements
The movement of ipv6_find_hdr() into exthdrs_core.c causes two small merge

are:
* ipv6_find_hdr() and ipv6_find_tlv() were both moved to the bottom of
exthdrs_core.c. Both should stay.
* A new use of ipv6_find_hdr() was added to net/netfilter/ipvs/ip_vs_core.c

With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction
based on failures" reverted, Zdenek Kabelac reported the following
Hmm, so it's just took longer to hit the problem and observe
kswapd0 spinning on my CPU again - it's not as endless like before -
but still it easily eats minutes - it helps to turn off Firefox
or TB (memory hungry apps) so kswapd0 stops soon - and restart
those apps again. (And I still have like >1GB of cached memory)
kswapd0 R running task 0 30 2 0x00000000
Call Trace:
preempt_schedule+0x42/0x60
_raw_spin_unlock+0x55/0x60
put_super+0x31/0x40
drop_super+0x22/0x30
prune_super+0x149/0x1b0
shrink_slab+0xba/0x510
The sysrq+m indicates the system has no swap so it'll never reclaim
anonymous pages as part of reclaim/compaction. That is one part of the
problem but not the root cause as file-backed pages could also be
reclaimed.
The likely underlying problem is that kswapd is woken up or kept awake
for each THP allocation request in the page allocator slow path.
If compaction fails for the requesting process then compaction will be
deferred for a time and direct reclaim is avoided. However, if there
are a storm of THP requests that are simply rejected, it will still be
the the case that kswapd is awake for a prolonged period of time as
pgdat->kswapd_max_order is updated each time. This is noticed by the
main kswapd() loop and it will not call kswapd_try_to_sleep(). Instead
it will loopp, shrinking a small number of pages and calling
shrink_slab() on each iteration.
The temptation is to supply a patch that checks if kswapd was woken for
THP and if so ignore pgdat->kswapd_max_order but it'll be a hack and not
backed up by proper testing. As 3.7 is very close to release and this
is not a bug we should release with, a safer path is to revert "mm:
remove __GFP_NO_KSWAPD" for now and revisit it with the view to ironing
out the balance_pgdat() logic in general.

Instead of having the getsockopt() of SO_BINDTODEVICE return an index, which
will then require another call like if_indextoname() to get the actual interface

This also matches the existing man page description on socket(7) which mentions
the argument being an interface name.
If the value has not been set, zero is returned and optlen will be set to zero
to indicate there is no interface name present.

GMAC devices newer than databook 3.40 has an embedded timer
that can be used for mitigating the number of interrupts.
So this patch adds this optimizations.
At any rate, the Rx watchdog can be disable (on bugged HW) by
passing from the platform the riwt_off field.
In this implementation the rx timer stored in the Reg9 is fixed
to the max value. This will be tuned by using ethtool.
V2: added a platform parameter to force to disable the rx-watchdog
for example on new core where it is bugged.
V3: do not disable NAPI when Rx watchdog is used.
V4: a new extra statistic field has been added to show the early
receive status in the interrupt handler.
This patch also adds an extra check to avoid to call
napi_schedule when the DMA_INTR_ENA_RIE bit is disabled in the

of/address: sparc: Declare of_iomap as an extern function for sparc again
This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.
The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.
This fix takes the same approach as 0bce04b that solved the equivalent problem

That patch tried to fix a issue when calculating zone->present_pages,
but it caused a regression on 32bit systems with HIGHMEM. With that
change, reset_zone_present_pages() resets all zone->present_pages to
zero, and fixup_zone_present_pages() is called to recalculate
zone->present_pages when the boot allocator frees core memory pages into
buddy allocator. Because highmem pages are not freed by bootmem
allocator, all highmem zones' present_pages becomes zero.
Various options for improving the situation are being discussed but for
now, let's return to the 3.6 code.

When MEMCG is configured on (even when it's disabled by boot option),
when adding or removing a page to/from its lru list, the zone pointer
used for stats updates is nowadays taken from the struct lruvec. (On
many configurations, calculating zone from page is slower.)
But we have no code to update all the lruvecs (per zone, per memcg) when
a memory node is hotadded. Here's an extract from the oops which
results when running numactl to bind a program to a newly onlined node:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000f60
IP: __mod_zone_page_state+0x9/0x60
Pid: 1219, comm: numactl Not tainted 3.6.0-rc5+ #180 Bochs Bochs
Process numactl (pid: 1219, threadinfo ffff880039abc000, task ffff8800383c4ce0)
Call Trace:
__pagevec_lru_add_fn+0xdf/0x140
pagevec_lru_move_fn+0xb1/0x100
__pagevec_lru_add+0x1c/0x30
lru_add_drain_cpu+0xa3/0x130
lru_add_drain+0x2f/0x40
...
The natural solution might be to use a memcg callback whenever memory is
hotadded; but that solution has not been scoped out, and it happens that
we do have an easy location at which to update lruvec->zone. The lruvec
pointer is discovered either by mem_cgroup_zone_lruvec() or by
mem_cgroup_page_lruvec(), and both of those do know the right zone.
So check and set lruvec->zone in those; and remove the inadequate
attempt to set lruvec->zone from lruvec_init(), which is called before
NODE_DATA(node) has been allocated in such cases.
Ah, there was one exceptionr. For no particularly good reason,
mem_cgroup_force_empty_list() has its own code for deciding lruvec.
Change it to use the standard mem_cgroup_zone_lruvec() and
mem_cgroup_get_lru_size() too. In fact it was already safe against such
an oops (the lru lists in danger could only be empty), but we're better
proofed against future changes this way.
I've marked this for stable (3.6) since we introduced the problem in 3.5
(now closed to stable); but I have no idea if this is the only fix
needed to get memory hotadd working with memcg in 3.6, and received no
answer when I enquired twice before.

We've been sitting on this longer than we meant to due to travel and

Biggest changes are from a batch of OMAP bugfixes, but there are a
few for the broader set of SoCs too (bcm2835, pxa, highbank, tegra,
at91 and i.MX).
The OMAP patches contain some fixes for MUSB/PHY on omap4 which
ends up being a bit on the large side but needed for legacy (non-DT)
platforms. Beyond that there are a handful of hwmod/pm changes.
So, fairly noncontroversial stuff all in all, and as usual around this

Users of GCC 4.7 have reported compiler errors due to having inline
applied to function declarations in clk-provider.h. The definitions
exist in drivers/clk/clk.c. An example error:
In file included from arch/arm/mach-omap2/clockdomain.c:25:0:
arch/arm/mach-omap2/clockdomain.c: In function ‘clkdm_clk_disable’:
include/linux/clk-provider.h:338:12: error: inlining failed in call to always_inline ‘__clk_get_enable_count’: function body not available
arch/arm/mach-omap2/clockdomain.c:1001:28: error: called from here
make[1]: *** [arch/arm/mach-omap2/clockdomain.o] Error 1
make: *** [arch/arm/mach-omap2] Error 2
This patch removes the use of inline from include/linux/clk-provider.h
but keeps the function definitions in drivers/clk/clk.c as inlined since
they are one-liners.

[mturquette@linaro.org: improved subject, added changelog]
Instead of having a host of different register offsets in the device tree,
this patch simplifies the CPSW code by letting the driver set the proper
register offsets automatically, based on the CPSW version.

====================
Included is a Bluetooth pull -- Gustavo says:
"These are the Bluetooth bits for inclusion in 3.8, there is basically one big
thing here which is the High Speed patches from Andrei, he did a lot of work on
A2MP and management of AMP devices. The rest are mostly clean up and bug
fixes."
Also included is an NFC pull -- Samuel says:
"With this one we have:
- pn544 p2p support.
- pn544 physical and HCI layers separation. We are getting the pn544 driver
ready to support non i2c physical layers.
- LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery
protocol.
- LLCP datagram sockets (connection less) support.
- IDR library usage for NFC devices indexes assignement.
- NFC netlink extension for setting and getting LLCP link characteristics.
- Various code style fixes and cleanups spread over the pn533, LLCP, HCI and
pn544 code."
There are a couple of mac80211 pulls as well -- Johannes says:
"Please pull my mac80211-next tree to get the first round of new features
for 3.8. We have:
* finally, the mac80211 multi-channel work
* scan improvements:
- bg scan
- scan flush
- forced AP scan
* cfg80211 tracing
* a bit of new code to allow implementing SAE (secure authentication of
equals) in managed mode
Along with a few random improvements, features and fixes."
and...
"Please pull from mac80211-next (per below pull request) to get a few
updates. Most important is probably the fix for the WDS regression that
my previous pull request introduced. Other than that, I have some
tracing code, two mesh updates and a change to allow drivers to
calculate the AES CMAC subkeys without having to implement the GF_mulx
operation themselves."
On top of that are the usual updates to iwlwifi, ath9k, rt2x00,
brcmfmac, mwifiex, and a few others here and there. Of note is the
addition of the ar5523 driver, ported from an original FreeBSD driver.

- Also refactor the conditional to use the existing tg3_pci_tbl array.
- Set flags in the driver_data field of the pci_device_id structure to
identify these devices.
- Add PCI_DEVICE_SUB() to pci.h to declare PCI 4-part IDs to match these
devices.

__IPTUNNEL_XMIT() is an ugly macro, convert it to a static
inline function, so make it more readable.
IPTUNNEL_XMIT() is unused, just remove it.

This patch introduces a new knob ndisc_notify. If enabled, the kernel
will transmit an unsolicited neighbour advertisement on link-layer address
change to update the neighbour tables of the corresponding hosts more quickly.
This is the equivalent to arp_notify in ipv4 world.
