[ Upstream commit 804689ad2d9b66d0d3920b48cf05881049d44589 ]

For failed commands with valid sense data (e.g. NCQ commands),
scsi_check_sense() is used in ata_analyze_tf() to determine if the
command can be retried. In such case, rely on this decision and ignore
the command error mask based decision done in ata_worth_retry().

This fixes useless retries of commands such as unaligned writes on zoned
disks (TYPE_ZAC).

<title>ahci: Disable LPM on Lenovo 50 series laptops with a too old BIOS</title>

<id>urn:sha1:1fb3563fac7efaf0f2b8796f9f595b3209a79db9</id>
<content type='text'>
commit 240630e61870e62e39a97225048f9945848fa5f5 upstream.

There have been several reports of LPM related hard freezes about once
a day on multiple Lenovo 50 series models. Strange enough these reports
where not disk model specific as LPM issues usually are and some users
with the exact same disk + laptop where seeing them while other users
where not seeing these issues.

It turns out that enabling LPM triggers a firmware bug somewhere, which
has been fixed in later BIOS versions.

This commit adds a new ahci_broken_lpm() function and a new ATA_FLAG_NO_LPM
for dealing with this.

The ahci_broken_lpm() function contains DMI match info for the 4 models
which are known to be affected by this and the DMI BIOS date field for
known good BIOS versions. If the BIOS date is older then the one in the
table LPM will be disabled and a warning will be printed.

Note the BIOS dates are for known good versions, some older versions may
work too, but we don't know for sure, the table is using dates from BIOS
versions for which users have confirmed that upgrading to that version
makes the problem go away.

Unfortunately I've been unable to get hold of the reporter who reported
that BIOS version 2.35 fixed the problems on the W541 for him. I've been
able to verify the DMI_SYS_VENDOR and DMI_PRODUCT_VERSION from an older
dmidecode, but I don't know the exact BIOS date as reported in the DMI.
Lenovo keeps a changelog with dates in their release notes, but the
dates there are the release dates not the build dates which are in DMI.
So I've chosen to set the date to which we compare to one day past the
release date of the 2.34 BIOS. I plan to fix this with a follow up
commit once I've the necessary info.

commit 6edf1d4cb0acde3a0a5dac849f33031bd7abb7b1 upstream.

If the ALL bit is set in the ZBC_OUT command, the command zone ID field
(block) should be ignored.

commit b320a0a9f23c98f21631eb27bcbbca91c79b1c6e upstream.

The block (LBA) specified must not exceed the last addressable LBA,
which is dev-&gt;nr_sectors - 1. So fix the correct check is
"if (block &gt;= dev-&gt;n_sectors)" and not "if (block &gt; dev-&gt;n_sectords)".

Additionally, the asc/ascq to return for an LBA that is not a zone start
LBA should be ILLEGAL REQUEST, regardless if the bad LBA is out of
range.

<title>libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk</title>

<id>urn:sha1:0667483adeeefdedd21cc636cd224632d5570980</id>
<content type='text'>
commit 2cfce3a86b64b53f0a70e92a6a659c720c319b45 upstream.

Commit 184add2ca23c ("libata: Apply NOLPM quirk for SanDisk
SD7UB3Q*G1001 SSDs") disabled LPM for SanDisk SD7UB3Q*G1001 SSDs.

This has lead to several reports of users of that SSD where LPM
was working fine and who know have a significantly increased idle
power consumption on their laptops.

Likely there is another problem on the T450s from the original
reporter which gets exposed by the uncore reaching deeper sleep
states (higher PC-states) due to LPM being enabled. The problem as
reported, a hardfreeze about once a day, already did not sound like
it would be caused by LPM and the reports of the SSD working fine
confirm this. The original reporter is ok with dropping the quirk.

A X250 user has reported the same hard freeze problem and for him
the problem went away after unrelated updates, I suspect some GPU
driver stack changes fixed things.

TL;DR: The original reporters problem were triggered by LPM but not
an LPM issue, so drop the quirk for the SSD in question.

<title>ata: ahci: mvebu: override ahci_stop_engine for mvebu AHCI</title>

[ Upstream commit daa2e3bdbb0b3e691cf20a042350817310cb8cb5 ]

There is an issue(Errata Ref#226) that the SATA can not be
detected via SATA Port-MultiPlayer(PMP) with following
error log:
  ata1.15: PMP product ID mismatch
  ata1.15: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
  ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0'
  ata1.15: PMP revalidation failed (errno=-19)

After debugging, the reason is found that the value Port-x
FIS-based Switching Control(PxFBS@0x40) become wrong.
According to design, the bits[11:8, 0] of register PxFBS
are cleared when Port Command and Status (0x18) bit[0]
changes its value from 1 to 0, i.e. falling edge of Port
Command and Status bit[0] sends PULSE that resets PxFBS
bits[11:8; 0].
So it needs a mvebu SATA WA to save the port PxFBS register
before PxCMD ST write and restore it afterwards.

This patch implements the WA in a separate function of
ahci_mvebu_stop_engine to override ahci_stop_gngine.

[ Upstream commit fa89f53bd7288d6aa7a982841119e7123faf5a53 ]

Marvell armada37xx, armada7k and armada8k share the same
AHCI sata controller IP, and currently there is an issue
(Errata Ref#226)that the SATA can not be detected via SATA
Port-MultiPlayer(PMP). After debugging, the reason is
found that the value of Port-x FIS-based Switching Control
(PxFBS@0x40) became wrong.
According to design, the bits[11:8, 0] of register PxFBS
are cleared when Port Command and Status (0x18) bit[0]
changes its value from 1 to 0, i.e. falling edge of Port
Command and Status bit[0] sends PULSE that resets PxFBS
bits[11:8; 0].
So it needs save the port PxFBS register before PxCMD
ST write and restore the port PxFBS register afterwards
in ahci_stop_engine().

This commit allows drivers to override ahci_stop_engine
behavior for use by the Marvell AHCI driver(and potentially
other drivers in the future).
