When building a 64bit kernel sometimes functions in the .init section were not
able to reach the standard kernel function. Main reason for this problem is,
that the linkage tables (.plt, .opd, .dlt) tend to become pretty huge and thus
the distance gets too big for short calls.
One option to avoid this is to use the -mlong-calls compiler option, but this
increases the binary size and introduces a performance penalty.
Instead, with this patch we just lay out the binary differently. Init code is
stored first, followed by text, R/O and finally R/W data. This means, that init
and text code is now much closer to each other, which is sufficient to reach
each other by short calls.

locale-gen on Debian showed a strange problem on parisc:
mmap2(NULL, 536870912, PROT_NONE, MAP_SHARED, 3, 0) = 0x42a54000
mmap2(0x42a54000, 103860, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 3, 0) = -1 EINVAL (Invalid argument)
Basically it was just trying to re-mmap() a file at the same address
which it was given by a previous mmap() call. But this remapping failed
with EINVAL.
The problem is, that when MAP_FIXED and MAP_SHARED flags were used, we didn't
included the mapping-based offset when we verified the alignment of the given
fixed address against the offset which we calculated it in the previous call.

Intel Wired LAN Driver Updates
This series contains updates to igb, e1000 and ixgbe.
Akeem provides a igb fix where WOL was being reported as supported on
some ethernet devices which did not have that capability.
Yanjun provides a fix for e1000 which is similar to a previous fix
for e1000e commit bb9e44d0d0 ("e1000e: prevent oops when adapter is
being closed and reset simultaneously"), where the same issue was
observed on the older e1000 cards.
Vladimir Davydov provides 2 e1000 fixes. The first fixes a lockdep
warning e1000_down() tries to synchronously cancel e1000 auxiliary
works (reset_task, watchdog_task, phy_info_task and fifo_stall_task)
which take adapter->mutex in their handlers. The second patch is to
fix a possible race condition where reset_task() would be running
after adapter down.
John provides 2 fixes for ixgbe. First turns ixgbe_fwd_ring_down
to static and the second disables NETIF_F_HW_L2FW_DOFFLOAD by default
because it allows upper layer net devices to use queues in the hardware
to directly submit and receive skbs.
Mark Rustad provides a single patch for ixgbe to make
ixgbe_identify_qsfp_module_generic static to resolve compile
warnings.

On e1000_down(), we should ensure every asynchronous work is canceled
before proceeding. Since the watchdog_task can schedule other works
apart from itself, it should be stopped first, but currently it is
stopped after the reset_task. This can result in the following race
leading to the reset_task running after the module unload:
e1000_down_and_stop(): e1000_watchdog():
---------------------- -----------------
cancel_work_sync(reset_task)
schedule_work(reset_task)
cancel_delayed_work_sync(watchdog_task)
The patch moves cancel_delayed_work_sync(watchdog_task) at the beginning
of e1000_down_and_stop() thus ensuring the race is impossible.

== The issue background ==
The problem occurs, because e1000_down(), which is called under
adapter->mutex by e1000_reset_task(), tries to synchronously cancel
e1000 auxiliary works (reset_task, watchdog_task, phy_info_task,
fifo_stall_task), which take adapter->mutex in their handlers. So the
question is what does adapter->mutex protect there?
The adapter->mutex was introduced by commit 0ef4ee ("e1000: convert to
private mutex from rtnl") as a replacement for rtnl_lock() taken in the
asynchronous handlers. It targeted on fixing a similar lockdep warning
issued when e1000_down() was called under rtnl_lock(), and it fixed it,
but unfortunately it introduced the lockdep warning described above.
Anyway, that said the source of this bug is that the asynchronous works
were made to take rtnl_lock() some time ago, so let's look deeper and
find why it was added there.
The rtnl_lock() was added to asynchronous handlers by commit 338c15
("e1000: fix occasional panic on unload") in order to prevent
asynchronous handlers from execution after the module is unloaded
(e1000_down() is called) as it follows from the comment to the commit:
> Net drivers in general have an issue where timers fired
> by mod_timer or work threads with schedule_work are running
> outside of the rtnl_lock.
>
> With no other lock protection these routines are vulnerable
> to races with driver unload or reset paths.
>
> The longer term solution to this might be a redesign with
> safer locks being taken in the driver to guarantee no
> reentrance, but for now a safe and effective fix is
> to take the rtnl_lock in these routines.
I'm not sure if this locking scheme fixed the problem or just made it
unlikely, although I incline to the latter. Anyway, this was long time
ago when e1000 auxiliary works were implemented as timers scheduling
real work handlers in their routines. The e1000_down() function only
canceled the timers, but left the real handlers running if they were
running, which could result in work execution after module unload.
Today, the e1000 driver uses sane delayed works instead of the pair
timer+work to implement its delayed asynchronous handlers, and the
e1000_down() synchronously cancels all the works so that the problem
that commit 338c15 tried to cope with disappeared, and we don't need any
locks in the handlers any more. Moreover, any locking there can
potentially result in a deadlock.
So, this patch reverts commits 0ef4ee and 338c15.

Currently macvlan will count received packets after calling each
vlans receive handler. Macvtap attempts to count the packet
yet again when the user reads the packet from the tap socket.
This code doesn't do this consistently either. Remove the
counting from macvtap and let only macvlan count received
packets.

- Remove preempt_count modifications in the arm64 IRQ handling code
since that's already dealt with in generic irq_enter/irq_exit
- PTE_PROT_NONE bit moved higher up to avoid overlapping with the
hardware bits (for PROT_NONE mappings which are pte_present)
- Big-endian fixes for ptrace support
- Asynchronous aborts unmasking while in the kernel
- pgprot_writecombine() change to create Normal NonCacheable memory
rather than Device GRE

Pull workqueue fixes from Tejun Heo:
"This contains one important fix. The NUMA support added a while back
broke ordering guarantees on ordered workqueues. It was enforced by
having single frontend interface with @max_active == 1 but the NUMA
support puts multiple interfaces on unbound workqueues on NUMA
machines thus breaking the ordered guarantee. This is fixed by
disabling NUMA support on ordered workqueues.
The above and a couple other patches were sitting in for-3.12-fixes
but I forgot to push that out, so they ended up waiting a bit too
long. My aplogies.
Other fixes are minor"

"Fixes for three issues.
- cgroup destruction path could swamp system_wq possibly leading to
deadlock. This actually seems to happen in the wild with memcg
because memcg destruction path adds nested dependency on system_wq.
Resolved by isolating cgroup destruction work items on its
dedicated workqueue.
- Possible locking context deadlock through seqcount reported by
lockdep
- Memory leak under certain conditions"

Quite a few HD-Audio fixes, a WUSB audio fix and a fix for FireWire
audio. The HD-audio part contains a couple of fixes for the generic
parser, and these are the only intrusive fixes. The rest are mostly

Pull vfs dentry reference count fix from Al Viro.
This fixes a possible inode_permission NULL pointer dereference (and
other problems) that were due to the root dentry count being decremented
too much. In commit 48a066e72d ("RCU'd vfsmounts") the placement of
clearing the LOOKUP_RCU bit changed, and we then returned failure of
incrementing the lockref on the parent dentry with LOOKUP_RCU cleared.
But that meant we needed to go through the same cleanup routines that
the later failures did wrt LOOKUP_ROOT and nd->root.
