This reverts commit 3c2e7f7de3240216042b61073803b61b9b3cfb22.
Initializing the mapping from MTRR to PAT values was reported to
fail nondeterministically, and it also caused extremely slow boot
(due to caching getting disabled---bug 103321) with assigned devices.

As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state. Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.
We already did this for the IPC semaphore code (see commit e8577d1f0329:
"ipc/sem.c: fully initialize sem_array before making it visible") but we
clearly forgot about msg and shm.

Both new_steering_entry() and existing_steering_entry() return values
based on their success or failure, but currently they fall through
silently. This can make troubleshooting difficult, as we were unable
to tell which one of these two functions returned errors or
specifically what code was returned. This patch remedies that
situation by passing the return codes to err, which is returned by
mlx4_qp_attach_common() itself.
This also addresses a leak in the call to mlx4_bitmap_free() as well.

Earlier patch 6ae459bda tried to detect void ckecksum partial
skb by comparing pull length to checksum offset. But it does
not work for all cases since checksum-offset depends on
updates to skb->data.
Following patch fixes it by validating checksum start offset
after skb-data pointer is updated. Negative value of checksum
offset start means there is no need to checksum.

====================
af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag
This patch set implements a bugfix for kernel.org bugzilla #12323, allowing
MSG_PEEK to return all queued data on the unix domain socket, not just the
data contained in a single SKB.
This is the v3 version of this patch, which includes a suggested modification
by Eric Dumazet to convert the unix_sk() conversion macro to a static inline
function. These patches are independent and can be applied separately.
This set was tested over a 24-hour period, utilizing a loop continually
executing the bugzilla issue attached python code. It was instrumented with
a pr_err_once() ([ 13.798683] unix: went there at least one time).
v2->v3:
- Added Eric Dumazet's suggestion for #define to static inline
- Fixed an issue calling unix_state_lock() with an invalid argument
v3->v4:
- Eliminated an XXX comment
- Changed from goto unlock to explicit unix_state_unlock() and break

AF_UNIX sockets now return multiple skbs from recv() when MSG_PEEK flag
is set.
This is referenced in kernel bugzilla #12323 @
https://bugzilla.kernel.org/show_bug.cgi?id=12323
As described both in the BZ and lkml thread @
http://lkml.org/lkml/2008/1/8/444 calling recv() with MSG_PEEK on an
AF_UNIX socket only reads a single skb, where the desired effect is
to return as much skb data has been queued, until hitting the recv
buffer size (whichever comes first).
The modified MSG_PEEK path will now move to the next skb in the tree
and jump to the again: label, rather than following the natural loop
structure. This requires duplicating some of the loop head actions.
This was tested using the python socketpair python code attached to
the bugzilla issue.

While the lockdep splat is a false positive, becuase path_openat holds i_mutex
of the parent directory and ubifs_init_security() tries to acquire i_mutex
of a new inode, it reveals that taking i_mutex in ubifs_init_security() is
in vain because it is only being called in the inode allocation path
and therefore nobody else can see the inode yet.

Move pxamci to mmc slot-gpio API to fix interrupt request.
It fixes the case where the card detection is on a gpio expander, on I2C
for example on zylonite board. In this case, the card detect netsted
interrupt is called from a threaded interrupt. The request_irq() fails,
because a hard irq cannot be a nested interrupt from a threaded
interrupt (set __setup_irq()).
This was tested on zylonite and mioa701 boards.

In recent allwinner kernel sources the mmc clk-delay settings have been
slightly tweaked, and for sun9i they are completely different then what
we are using.
This commit brings us in sync with what allwinner does, fixing problems
accessing sdcards on some A33 devices (and likely others).
For pre sun9i hardware this makes the following changes:
-At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk)
-At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk)
This also drops the clk-delay calculation for clocks > 50 MHz, we do
not need this as we've: mmc->f_max = 50000000, and the delays in the
old code were not correct (at 100 MHz the delay must be a multiple of 60,
at 200 MHz a multiple of 120).

When CONFIG_GPIOLIB is unset, its stubs will return -ENOSYS. That means
when the mmc core parses DT for CD/WP GPIOs via mmc_of_parse(), -ENOSYS
becomes propagated to the caller. Typically this means that the mmc host
driver fails to probe.
As the CD/WP GPIOs are already treated as optional, let's extend that to
cover the case when CONFIG_GPIOLIB is unset.

The size of the MAC register dump used to be the size specified by the
reg property in the device tree. Userland has no good way of finding
out that size, and it was not specified consistently for each MAC type,
so ethtool would end up printing junk at the end of the register dump
if the device tree didn't match the size it assumed.
Using the new version numbers indicates unambiguously that the size of
the MAC register dump is dependent only on the MAC type.

A case can occur when sctp_accept() is called by the user during
a heartbeat timeout event after the 4-way handshake. Since
sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
bh_sock_lock in sctp_generate_heartbeat_event() will be taken with
the listening socket but released with the new association socket.
The result is a deadlock on any future attempts to take the listening
socket lock.
Note that this race can occur with other SCTP timeouts that take
the bh_lock_sock() in the event sctp_accept() is called.

CslRx/12087 is trying to release lock (slock-AF_INET) at:
[<ffffffffa01bcae0>] sctp_generate_timeout_event+0x40/0xe0 [sctp]
but there are no more locks to release!
other info that might help us debug this:
2 locks held by CslRx/12087:
#0: (&asoc->timers[i]){+.-...}, at: [<ffffffff8108ce1f>] run_timer_softirq+0x16f/0x3e0
#1: (slock-AF_INET){+.-...}, at: [<ffffffffa01bcac3>] sctp_generate_timeout_event+0x23/0xe0 [sctp]
Ensure the socket taken is also the same one that is released by
saving a copy of the socket before entering the timeout event
critical section.

It's possible that while we are waiting for the spinlock, another
entity (that owns the spinlock) has shut down the admin queue.
If we then attempt to use the queue, we will panic.
Add a check for this condition on the receive side. This matches
an existing check on the send queue side.

Previously to this patch, the hardware was removing
VLAN tags from the inner header of VXLAN packets. The
hardware configuration can be changed to leave the
packet alone since that is what the linux stack
expects for this type of VLAN in VXLAN packet.

system MSR"
Shifting pvclock_vcpu_time_info.system_time on write to KVM system time
MSR is a change of ABI. Probably only 2.6.16 based SLES 10 breaks due
to its custom enhancements to kvmclock, but KVM never declared the MSR
only for one-shot initialization. (Doc says that only one write is
needed.)
This reverts commit b7e60c5aedd2b63f16ef06fde4f81ca032211bc5.
And adds a note to the definition of PVCLOCK_COUNTS_FROM_ZERO.

If I2C is built as module, the iTCO watchdog driver must be built as module
as well. I2C_I801 must only be selected if I2C is configured.
This fixes the following build errors, seen if I2C=m and ITCO_WDT=y.
i2c-i801.c:(.text+0x2bf055): undefined reference to `i2c_del_adapter'

Currently poweroff/halt results in a reboot on the Raspberry Pi.
The firmware uses the RSTS register to know which partiton to
boot from. The partiton value is spread into bits
0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by
the firmware to indicate halt.
The firmware made this change in 19 Aug 2013 and was matched
by the downstream commit:
