Commit c060f943d092 ("mm: use aligned zone start for pfn_to_bitidx
calculation") fixed out calculation of the index into the pageblock
bitmap when a !SPARSEMEM zome was not aligned to pageblock_nr_pages.
However, the _allocation_ of that bitmap had never taken this alignment
requirement into accout, so depending on the exact size and alignment of
the zone, the use of that index could then access past the allocation,
resulting in some very subtle memory corruption.
This was reported (and bisected) by Ingo Molnar: one of his random
config builds would hang with certain very specific kernel command line
options.
In the meantime, commit c060f943d092 has been marked for stable, so this
fix needs to be back-ported to the stable kernels that backported the
commit to use the right alignment.

Upper case macros for various chip attributes are slightly
difficult to read and are a bit out of characterto the other
tg3_<foo> attribute functions.
Convert:
GET_ASIC_REV(tp->pci_chip_rev_id) -> tg3_asic_rev(tp)
GET_CHIP_REV(tp->pci_chip_rev_id) -> tg3_chip_rev(tp)
Remove:
GET_METAL_REV(tp->pci_chip_rev_id) -> tg3_metal_rev(tp) (unused)
Add:
tg3_chip_rev_id(tp) for tp->pci_chip_rev_id so access styles
are similar to tg3_asic_rev and tg3_chip_rev.
These macros are not converted to static inline functions
because gcc (tested with 4.7.2) is currently unable to
optimize the object code it produces the same way and code
is otherwise larger.

Jeff Kirsher says:
====================
This series contains updates to e1000, e1000e, igb, igbvf and ixgbe.
The e1000, e1000e, igb and igbvf are single patch changes and the
remaining 11 patches are all against ixgbe.
The e1000 patch is a comment cleanup to align e1000 with the code
commenting style for /drivers/net. It also contains a few other white
space cleanups (i.e. fix lines over 80 char, remove unnecessary blank
lines and fix the use of tabs/spaces).
The e1000e patch from Koki (Fujitsu) adds a warning when link speed is
downgraded due to SmartSpeed.
The igb patch from Stefan (Red Hat) increases the timeout in the ethtool
offline self-test because some i350 adapters would sometimes fail the
self-test because link auto negotiation may take longer than the current
4 second timeout.
The igbvf patch from Alex is meant to address several race issues that
become possible because next_to_watch could possibly be set to a value
that shows that the descriptor is done when it is not. In order to correct
that we instead make next_to_watch a pointer that is set to NULL during
cleanup, and set to the eop_desc after the descriptor rings have been written.
The remaining patches for ixgbe are a mix of fixes and added support as well
as some cleanup. Most notably is the added support for displaying the
number of Tx/Rx channels via ethtool by Alex. Also Aurélien adds the
ability for reading data from SFP+ modules over i2c for diagnostic
monitoring.

If we pass fd of memory.usage_in_bytes of cgroup A to cgroup.event_control
of cgroup B, then we won't get memory usage notification from A but B!
What's worse, if A and B are in different mount hierarchy, we'll end up
accessing NULL pointer!
Disallow this kind of invalid usage.

Larry noticed (and bisected) that commit df881293c6ba9a12868491a717b25
"cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_station"
broke secure connections. This is is the case only for drivers that
don't support TDLS, where any kind of change, even just the change of
authorized flag that is required for normal operation, was rejected
now. To fix this, remove the checks. I have some patches that will add
proper verification for all the different cases later.

commit 205a872bd6f9a9a09ef035ef1e90185a8245cc58 ("cgroup: fix lockdep
warning for event_control") solved a deadlock by introducing a new
bug.
Move cgrp->event_list to a temporary list doesn't mean you can traverse
this list locklessly, because at the same time cgroup_event_wake() can
be called and remove the event from the list. The result of this race
is disastrous.
We adopt the way how kvm irqfd code implements race-free event removal,
which is now described in the comments in cgroup_event_wake().
v3:
- call eventfd_signal() no matter it's eventfd close or cgroup removal
that removes the cgroup event.

rename() will change dentry->d_name. The result of this race can
be worse than seeing partially rewritten name, but we might access
a stale pointer because rename() will re-allocate memory to hold
a longer name.
It's safe in the protection of dentry->d_lock.
v2: check NULL dentry before acquiring dentry lock.

In cgroup_exit() put_css_set_taskexit() is called without any lock,
which might lead to accessing a freed cgroup:

cgroup_exit()
put_css_set_taskexit()
atomic_dec(cgrp->count);
rmdir();

check_for_release(cgrp);
rcu_read_lock() can be used to make sure the cgroup is alive.

pm_idle appears in no generic Linux code,

Thus, pm_idle should not be declared in pm.h.

This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That
commit causes two kinds of breakage; it breaks registration of AMBA
devices when one of the parent nodes already contains overlapping
resource regions, and it breaks calls to request_region() by device
drivers in certain conditions where there are overlapping memory
regions. Both of these problems can probably be fixed, but it is better
to back out the commit and get a proper fix designed before trying again.
