Fix dm-raid flush support.
Both md and dm have support for flush, but the dm-raid target
forgot to set the flag to indicate that flushes should be
passed on. (Important for data integrity e.g. with writeback cache
enabled.)

The 'rebuild' parameter is used to rebuild individual devices in an
array (e.g. resynchronize a RAID1 device or recalculate a parity device
in higher RAID). The MD_CHANGE_DEVS flag must be set when this
parameter is given in order to write out the superblocks and make the
change take immediate effect. The code that handles new devices in
super_load already sets MD_CHANGE_DEVS and 'FirstUse'. (The 'FirstUse'
flag was being set as a special case for rebuilds in
super_init_validation.)
Add a condition for rebuilds in super_load to take care of both flags
without the special case in 'super_init_validation'.

The following BUG is hit on the first read that is submitted to a dm
flakey test device while the device is "down" if the corrupt_bio_byte

A global delay parameter has the side effect of being overwritten with 0 if a
single ZL2004 or ZL6105 is instantiated. If other chips supported by the same
driver are in the system, this will result in access errors for those chips.
To solve the problem, keep a per-instance copy of the delay parameter, and do
not change the original parameter.

Pull networking fixes from David Miller:
1) TCP can chop up SACK'd SKBs below below the unacked send sequence and
that breaks lots of stuff. Fix from Neal Cardwell.
2) There is code in ipv6 to properly join and leave the all-routers
multicast code when the forwarding setting is changed, but once
forwarding is turned on, we don't do the join for newly registered
devices. Fix from Li Wei.
3) Netfilter's NAT module autoload in ctnetlink drops a spinlock around
a sleeping call, problem is this code path doesn't actually hold that
lock. Fix from Pablo Neira Ayuso.
4) TG3 uses the wrong interfaces to hook into the new byte queue limit
support. It uses the device level interfaces, which is fine for
single queue devices, but on more recent chips this driver supports
multiqueue so we have to use the multiqueue BQL APIs. Fix from Tom
Herbert.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.
Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.
Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.

Production GMA3600/3650 hardware turns out to be subtly different to the
development platforms. This combined with a minor driver bug is causing
the kernel to hang on these platforms.
This patch does the following
- turn down a couple of messages that were meant to be debug and are
causing much confusion
- ensure the hotplug interrupt is disabled on Cedartrail systems.
- fix a bug where gtt roll mode called psbfb_sync, which tries to sync
the 2D engine. On other devices it is harmless as the 2D engine is
present but not in use when in gtt roll mode, on Cedartrail it causes
a hang
Without these changes 3.3-rc hangs on boot on Cedartrail based systems.

Pull networking fixes from David Miller:
1) TCP SACK processing can calculate an incorrect reordering value in
some cases, fix from Neal Cardwell.
2) tcp_mark_head_lost() can split SKBs in situations where it should
not, violating send queue invariants expected by other pieces of
code and thus resulting (eventually) in corrupted retransmit state

hw_flags of zero. Fix from Santosh Nayak.
4) Fix NULL deref in rt2x00, from Gabor Juhos.

the results. From Eric Dumazet.
7) Bridging code fails to check return value of ipv6_dev_get_saddr()
thus potentially leaving uninitialized garbage in the outgoing ipv6
header. From Ulrich Weber.
8) Due to rounding and a reversed operation on jiffies, bridge message
ages can go backwards instead of forwards, thus breaking STP. Fixes
from Joakim Tjernlund.
9) r8169 modifies Config* registers without properly holding the
Config9346 lock, resulting in corrupted IP fragments on some chips.

In 'ql_adapter_initialize'
the first call for 'spin_unlock_irqrestore()' is with hw_flags = 0,
which is as good as 'spin_unlock_irq()' (unconditional interrupt
enabling). If this is intended, then for better performance
'spin_unlock_irqrestore()' can be replaced with 'spin_unlock_irq()'
and 'spin_lock_irqsave()' can be replaced by 'spin_lock_irq()

Allow array field values out of range as per HID 1.11 specification,
section 6.2.25:
Rather than returning a single bit for each button in the group, an
array returns an index in each field that corresponds to the pressed
button (like keyboard scan codes). An out-of range value in and array
field is considered no controls asserted.
Apparently, "and" above is a typo and should be "an".
This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never
released.
The relevant part of Waltop tablet report descriptors is this:
0x09, 0x42, /* Usage (Tip Switch), */
0x09, 0x44, /* Usage (Barrel Switch), */
0x09, 0x46, /* Usage (Tablet Pick), */
0x15, 0x01, /* Logical Minimum (1), */
0x25, 0x03, /* Logical Maximum (3), */
0x75, 0x04, /* Report Size (4), */
0x95, 0x01, /* Report Count (1), */
0x80, /* Input, */
This is a regression fix for commit b4b583d ("HID: be more strict when
ignoring out-of-range fields").

Even if cards supports 1.8V I/O voltage those should anyway be
initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs.
Some eMMC and embedded SDIO devices are able to be initialized
at 1.8V as well, but it is better to be safe.
Do note that initialization in this context means that the card
has been completely powered off, otherwise the card will remain
at the last I/O voltage level that were negotitiated.
Due to the above being taken care of the suspend/resume issues
for UHS-I SD-cards has been fixed.

On a system with large pages (64k in my case), the following BUG is

This is because of a 64k request with a max_req_size of 64k-1 bytes.
The following patch fixes the problem by limiting the max_blk_count
such that max_blk_count * max_blk_size == max_req_size. I couldn't
pursuade the compiler to emit a shift instead of a div without encoding
the shift explicitly.

On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the
SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION
command. This works for SD cards. However, with MMC cards
the MMC_SET_BLOCK_COUNT command is used instead, but this
needs the same handling. Fix MMC cards by testing for the
MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53
board with a Transcend MMC+ card and eMMC.
The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this
is a regression for these boards introduced in 3.0; it should
go to 3.0/3.1/3.2-stable.

A recent commit "mmc: core: Use delayed work in clock gating framework"
(597dd9d79cfbbb1) introduced a default 200ms delay before clock gating
actually takes place. This means that every time an MMC interface
becomes idle it first stays on for 200ms before gating its clock. This
leads to increased power consumption and is therefore a clear regression.
This patch restores the original behaviour by setting the default delay
to 0. Users prioritising throughput over power efficiency can still
modify the delay via sysfs.
