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.

oom_badness() takes a totalpages argument which says how many pages are
available and it uses it as a base for the score calculation. The value
is calculated by mem_cgroup_get_limit which considers both limit and
total_swap_pages (resp. memsw portion of it).
This is usually correct but since fe35004fbf9e ("mm: avoid swapping out
with swappiness==0") we do not swap when swappiness is 0 which means
that we cannot really use up all the totalpages pages. This in turn
confuses oom score calculation if the memcg limit is much smaller than
the available swap because the used memory (capped by the limit) is
negligible comparing to totalpages so the resulting score is too small
if adj!=0 (typically task with CAP_SYS_ADMIN or non zero oom_score_adj).
A wrong process might be selected as result.
The problem can be worked around by checking mem_cgroup_swappiness==0
and not considering swap at all in such a case.

do_wp_page() sets mmun_called if mmun_start and mmun_end were
initialized and, if so, may call mmu_notifier_invalidate_range_end()
with these values. This doesn't prevent gcc from emitting a build
warning though:
mm/memory.c: In function `do_wp_page':
mm/memory.c:2530: warning: `mmun_start' may be used uninitialized in this function
mm/memory.c:2531: warning: `mmun_end' may be used uninitialized in this function
It's much easier to initialize the variables to impossible values and do
a simple comparison to determine if they were initialized to remove the
bool entirely.

John W. Linville says:
====================
This batch of fixes is intended for the 3.7 stream...
This includes a pull of the Bluetooth tree. Gustavo says:
"A few important fixes to go into 3.7. There is a new hw support by Marcos
Chaparro. Johan added a memory leak fix and hci device index list fix.
Also Marcel fixed a race condition in the device set up that was prevent the
bt monitor to work properly. Last, Paulo Sérgio added a fix to the error
status when pairing for LE fails. This was prevent userspace to work to handle
the failure properly."
Regarding the mac80211 pull, Johannes says:
"I have a locking fix for some SKB queues, a variable initialization to
avoid crashes in a certain failure case, another free_txskb fix from
Felix and another fix from him to avoid calling a stopped driver, a fix
for a (very unlikely) memory leak and a fix to not send null data
packets when resuming while not associated."
Regarding the iwlwifi pull, Johannes says:
"Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and
one to check DMA mapping errors, please pull."
On top of that, Johannes also included a wireless regulatory fix
to allow 40 MHz on channels 12 and 13 in world roaming mode. Also,
Hauke Mehrtens fixes a #ifdef typo in brcmfmac.

Included fixes are:
- update the client entry status flags when using the "early client
detection". This makes the Distributed AP isolation correctly work;
- transfer the client entry status flags when recovering the translation
table from another node. This makes the Distributed AP isolation correctly
work;
- prevent the "early client detection mechanism" to add clients belonging to
other backbone nodes in the same LAN. This breaks connectivity when using this
mechanism together with the Bridge Loop Avoidance
- process broadcast packets with the Bridge Loop Avoidance before any other
component. BLA can possibly drop the packets based on the source address. This
makes the "early client detection mechanism" correctly work when used with
BLA.

This is mostly a revert of 01dc52ebdf47 ("oom: remove deprecated oom_adj")
from Davidlohr Bueso.
It reintroduces /proc/pid/oom_adj for backwards compatibility with earlier
kernels. It simply scales the value linearly when /proc/pid/oom_score_adj
is written.
The major difference is that its scheduled removal is no longer included
in Documentation/feature-removal-schedule.txt. We do warn users with a
single printk, though, to suggest the more powerful and supported
/proc/pid/oom_score_adj interface.

Pull ARM SoC fixes from Olof Johansson:
"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

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

The logic in the BLA mechanism may decide to drop broadcast packets
because the node may still be in the setup phase. For this reason,
further broadcast processing like the early client detection mechanism
must be done only after the BLA check.
This patches moves the invocation to BLA before any other broadcast
processing.

The "early client detection" mechanism must not add clients belonging
to other backbone nodes. Such clients must be reached by directly
using the LAN instead of the mesh.

Flags carried by a change_entry have to be always copied into the
client entry as they may contain important attributes (e.g.
TT_CLIENT_WIFI).
For instance, a client added by means of the "early detection
mechanism" has no flag set at the beginning, so they must be updated once the
proper ADD event is received.

The kernel uses some default metric when routes are managed. For example, a
static route added with a metric set to 0 is inserted in the kernel with
metric 1024 (IP6_RT_PRIO_USER).
It is useful for routing daemons to know these values, to be able to set routes
without interfering with what the kernel does.

Just a few small things to fix regressions, somehow all patches from Jani:
- Fix dpms confusion about which platforms support intermediate modes on
vga.
- Revert the "ignore vbt for eDP bpc" patch, it breaks machines. This will
annoy mbp retina owners again, but windows machines seem to _really_
depend upon this. We can try to quirk the mbp retinas again in 3.8 and
backport the patch.
- Fix connector leaks when the sdvo setup failed, resulted in an OOPS
later on when trying to probe that connector (with it's encoder kfree'd
already).

The TTM page can be allocated from high memory. In such case it is
wrong to use the page_address(page) as the virtual address for the high memory
page.

This patch re-enables Energy Detect Power Down (EDPD) mode for the
LAN8710/LAN8720. EDPD mode was disabled in a previous commit,
(b629820d18fa65cc598390e4b9712fd5f83ee693), because it was causing the
PHY to not be able to detect a link when cold started without a cable
connected.
The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of
each other in order to set the ENERGYON bit and exit EDPD mode. If a
link partner does send the pulses within this interval, the PHY will
remained powered down.
This workaround will manually toggle the PHY on/off upon calls to
read_status in order to generate link test pulses if the link is down.
If a link partner is present, it will respond to the pulses, which will
cause the ENERGYON bit to be set and will cause the EDPD mode to be
exited.
