All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.Signed-off-by: Tejun Heo

Commit 130f4caf145c ("libata: Ensure ata_port probe has completed before
detach") may cause system freeze during suspend.Using async_synchronize_full() in PM callbacks is wrong, since async
callbacks that are already scheduled may wait for not-yet-scheduled
callbacks, causes a circular dependency.Instead of using big hammer like async_synchronize_full(), use async
cookie to make sure port probe are synced, without affecting other
scheduled PM callbacks.Fixes: 130f4caf145c ("libata: Ensure ata_port probe has completed before detach")

The docs toolchain doesn't recognise this pattern:
@link->[hw_]sata_spd_limit
As it can't really process it. So, instead, let's mark it with
a literal block markup:``link->[hw_]sata_spd_limit``
in order to get rid of the following warning:

ata_qc_complete_multiple() is called with a mask of the still active
tags.mv_sata doesn't have this information directly and instead calculates
the still active tags from the started tags (ap->qc_active) and the
finished tags as (ap->qc_active ^ done_mask)Since 28361c40368 the hw_tag and tag are no longer the same and the
equation is no longer valid. In ata_exec_internal_sg() ap->qc_active is
initialized as 1ULL << ATA_TAG_INTERNAL, but in hardware tag 0 is
started and this will be in done_mask on completion. ap->qc_active ^
done_mask becomes 0x100000000 ^ 0x1 = 0x100000001 and thus tag 0 used as
the internal tag will never be reported as completed.This is fixed by introducing ata_qc_get_active() which returns the
active hardware tags and calling it where appropriate.This is tested on mv_sata, but sata_fsl and sata_nv suffer from the same
problem. There is another case in sata_nv that most likely needs fixing
as well, but this looks a little different, so I wasn't confident enough
to change that.Fixes: 28361c403683 ("libata: add extra internal command")

The issue is that when CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, we may
attempt to detach the ata_port before it has been probed.This is because the ata_ports are async probed, meaning that there is no
guarantee that the ata_port has probed prior to detach. When the ata_port
does probe in this scenario, we get all sorts of issues as the detach may
have already happened.Fix by ensuring synchronisation with async_synchronize_full(). We could
alternatively use the cookie returned from the ata_port probe
async_schedule() call, but that means managing the cookie, so more
complicated.Signed-off-by: John Garry

hen we're comparing the hardware completion mask passed in from the
driver with the internal tag pending mask, we need to account for the
fact that the internal tag is different from the hardware tag. If not,
then we can end up either prematurely completing the internal tag (since
it's not set in the hw mask), or simply flag an error:ata2: illegal qc_active transition (100000000->00000001)
If the internal tag is set, then swap that with the hardware tag in this
case before comparing with what the hardware reports.Fixes: 28361c403683 ("libata: add extra internal command")

Pull SCSI updates from James Bottomley:
"This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
hisi_sas, smartpqi, megaraid_sas, arcmsr.In addition, with the continuing absence of Nic we have target updates
for tcmu and target core (all with reviews and acks).The biggest observable change is going to be that we're (again) trying
to switch to mulitqueue as the default (a user can still override the
setting on the kernel command line).Other major core stuff is the removal of the remaining Microchannel
drivers, an update of the internal timers and some reworks of
completion and result handling"* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (203 commits)

Currently when min_power policy is selected, the partial low power state
is not entered and link will try aggressively enter to only slumber state.
Add a new policy which still enable DEVSLP but also try to enter partial
low power state. This policy is presented as "min_power_with_partial".For information the difference between partial and slumber
Partial – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ns.
Slumber – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ms.
Devslp – PHY logic is powered down. The link PM exit latency from this
state to active state maximum is 20 ms, unless otherwise specified by
DETO.Suggested-and-reviewed-by: Hans de Goede
