For some reason, a lot of port-multipliers have issues with softreset.
SIMG [34]7x series port-multipliers have been quite erratic in this
regard. I recall that it was better with some firmware revisions and
the current list of quirks worked fine for a while. I think it got
worse with later firmwares or maybe my test coverage wasn't good
enough. Anyways, HPA is reporting that his 3726 setup suffers SRST
failures and then the PMP gets confused and fails to probe the last
port.
The hope was that we try to stick to the standard as much as possible
and soonish the PMPs and their firmwares will improve in quality, so
the quirk list was kept to minimum. Well, it seems like that's never
gonna happen.
Let's set NO_SRST for all [34]7x PMPs so that whatever remaining
userbase of the device suffer the least. Maybe we should do the same
for 57xx's but unfortunately I don't have any device left to test and
I'm not even sure 57xx's have ever been made widely available, so
let's leave those alone for now.

ata_link_online() check in ahci_error_intr() is unnecessary, it should
be removed otherwise may lead to lockup with FBS enabled PMP.

When compiling the driver with gcc 4.8, it gives the following warning:
drivers/ata/sata_rcar.c: In function `sata_rcar_thaw':
drivers/ata/sata_rcar.c:183:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]
Fix the warning by explicit cast of the 'unsigned long' value to 'u32'.

The driver's interrupt handling code is too picky in deciding whether it should
handle an interrupt or not which causes completely unneeded spurious interrupts.
Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read
to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't
get cleared by writing to the SATAINTSTAT register in the interrupt mode we use.
Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for
enabled interrupts and we should clear only those interrupts that we have read
as active first time around, because else we have a race and risk clearing an
interrupt that can occur between read and write of the SATAINTSTAT register
and never registering it...

Iff bmdma_setup() has to stop a DMA transfer before starting a new
one, then the STOP bit in the ATAPI_CONTROL1 register will remain set
(it's only cleared when setting the START bit to 1) and then
bmdma_start() method will set both START and STOP bits simultaneously
which should abort the transfer being just started. Avoid that by
explicitly clearing the STOP bit in bmdma_start() method (in this case
it will be ignored on write).

libata honors DMADIR for regular commands, but not for internal commands
used (among other) during device initialisation.
This makes SATA-host-to-PATA-device bridges based on Silicon Image SiL3611
(such as "Abit Serillel 2") end up disabled when used with an ATAPI device
after a few tries.
Log output of the bridge being hot-plugged with an ATAPI drive:

Pull MIPS updates from Ralf Baechle:
- More work on DT support for various platforms
- Various fixes that were to late to make it straight into 3.9
- Improved platform support, in particular the Netlogic XLR and
BCM63xx, and the SEAD3 and Malta eval boards.
- Support for several Ralink SOC families.
- Complete support for the microMIPS ASE which basically reencodes the
existing MIPS32/MIPS64 ISA to use non-constant size instructions.
- Some fallout from LTO work which remove old cruft and will generally
make the MIPS kernel easier to maintain and resistant to compiler
optimization, even in absence of LTO.
- KVM support. While MIPS has announced hardware virtualization
extensions this KVM extension uses trap and emulate mode for
virtualization of MIPS32. More KVM work to add support for VZ
hardware virtualizaiton extensions and MIPS64 will probably already
be merged for 3.11.
Most of this has been sitting in -next for a long time. All defconfigs
have been build or run time tested except three for which fixes are being

sas_device_type
These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas. The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:
drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]
Fix by eliminating one of them. The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.

scsi_send_eh_cmnd() is calling queuecommand() directly, so
it needs to check the return value here.
The only valid return codes for queuecommand() are 'busy'
states, so we need to wait for a bit to allow the LLDD
to recover.
Based on an earlier patch from Wen Xiong.
[jejb: fix confusion between msec and jiffies values and other issues]
[bvanassche: correct stall_for interval]

Pull m68knommu updates from Greg Ungerer:
"The bulk of the changes are generalizing the ColdFire v3 core support
and adding in 537x CPU support. Also a couple of other bug fixes, one
to fix a reintroduction of a past bug in the romfs filesystem nommu
support."
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu:
m68knommu: enable Timer on coldfire 532x
m68knommu: fix ColdFire 5373/5329 QSPI base address
m68knommu: add support for configuring a Freescale M5373EVB board
m68knommu: add support for the ColdFire 537x family of CPUs
m68knommu: make ColdFire M532x platform support more v3 generic
m68knommu: create and use a common M53xx ColdFire class of CPUs
m68k: remove unused asm/dbg.h
m68k: Set ColdFire ACR1 cache mode depending on kernel configuration
romfs: fix nommu map length to keep inside filesystem
m68k: clean up unused "config ROMVECSIZE"

Generate a dm event when the amount of remaining thin pool metadata
space falls below a certain level.
The threshold is taken to be a quarter of the size of the metadata
device with a minimum threshold of 4MB.

Add a threshold callback function to the persistent data space map
interface for a subsequent patch to use.
dm-thin and dm-cache are interested in knowing when they're getting
low on metadata or data blocks. This patch introduces a new method
for registering a callback against a threshold.

Allow the dm thin pool metadata device to be extended.
Whenever a pool is resumed, detect whether the size of the metadata
device has increased, and if so, extend the metadata to use the new
space.

Support extending a dm persistent data metadata space map.
The extend itself is implemented by switching back to the boostrap
allocator and pointing to the new space. The extra bitmap indexes are
then allocated from the new space, and finally we switch back to the
proper space map ops and tweak the reference counts.

If a thin pool is created in read-only-metadata mode then only open the
metadata device read-only.
Previously it was always opened with FMODE_READ | FMODE_WRITE.
(Note that dm_get_device() still allows read-only dm devices to be used
read-write at the moment: If I create a read-only linear device for the
metadata, via dmsetup load --readonly, then I can still create a rw pool
out of it.)
