commit 7867b98dceb7741065c9c1b645136facad5c2e93 upstream.
When driver is loaded in Target/Dual mode, it creates QPair to support
MQ and allocates resources for each QPair. This Qpair initialization is
delayed until the FW personality is changed to Dual/Target mode by
issuing chip reset. At the time of chip reset firmware is re-initilized
in correct personality all the QPairs are initialized by sending
MBC_INITIALIZE_MULTIQ (001Fh).
This patch fixes memory leak by adding check to issue
MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the
flag is set for initiator mode, and clean up QPair resources correctly
during the driver unload. This MBX does not need to be issued for
Target/Dual mode because chip reset will reset ISP.

commit b0dcce746b32ac573343ad39cb3dc485030de95e upstream.
Original code acquires hardware_lock to add Abort IOCB onto driver
request queue for processing. However, abort_command() will also acquire
hardware lock to look up sp pointer before issuing abort IOCB command
resulting into a deadlock. This patch safely removes the possible
deadlock scenario by removing extra spinlock.

If user swaps one target port for another target port for same switch
port, the new target port is not being recognized by the driver. Current
code assumes that old Target port has recovered from link down. The fix
will ask switch what is the WWPN of a specific NportID (GPNID) rather
than assuming it's the same Target port which has came back.

commit 6c9f0ce0dffe64da2204f38b0fd90f3ae2a8903c upstream.
Commit 5e572cab92f0 ("tpm: Enable CLKRUN protocol for Braswell systems")
added logic in the TPM TIS driver to disable the Low Pin Count CLKRUN
signal during TPM transactions.
Unfortunately this breaks other devices that are attached to the LPC bus
like for example PS/2 mouse and keyboards.
One flaw with the logic is that it assumes that the CLKRUN is always
enabled, and so it unconditionally enables it after a TPM transaction.
But it could be that the CLKRUN# signal was already disabled in the LPC
bus and so after the driver probes, CLKRUN_EN will remain enabled which
may break other devices that are attached to the LPC bus but don't have
support for the CLKRUN protocol.

commit b3e958ce4c585bf666de249dc794971ebc62d2d3 upstream.
Commit 5e572cab92f0bb5 ("tpm: Enable CLKRUN protocol for Braswell
systems") disabled CLKRUN protocol during TPM transactions and re-enabled
once the transaction is completed. But there were still some corner cases
observed where, reading of TPM header failed for savestate command
while going to suspend, which resulted in suspend failure.
To fix this issue keep the CLKRUN protocol disabled for the entire
duration of a single TPM command and not disabling and re-enabling
again for every TPM transaction. For the other TPM accesses outside
TPM command flow, add a higher level of disabling and re-enabling
the CLKRUN protocol, instead of doing for every TPM transaction.

commit 2b3d89b402b085b08498e896c65267a145bed486 upstream.
Gen8 and prior Proliant systems supported the "CRU" interface
to firmware. This interfaces allows linux to "call back" into firmware
to source the cause of an NMI. This feature isn't fully utilized
as the actual source of the NMI isn't printed, the driver only
indicates that the source couldn't be determined when the call
fails.
With the advent of Gen9, iCRU replaces the CRU. The call back
feature is no longer available in firmware. To be compatible and
not attempt to call back into firmware on system not supporting CRU,
the SMBIOS table is consulted to determine if it is safe to
make the call back or not.
This results in about half of the driver code being devoted
to either making CRU calls or determing if it is safe to make
CRU calls. As noted, the driver isn't really using the results of
the CRU calls.
Furthermore, as a consequence of the Spectre security issue, the
BIOS/EFI calls are being wrapped into Spectre-disabling section.
Removing the call back in hpwdt_pretimeout assists in this effort.
As the CRU sourcing of the NMI isn't required for handling the
NMI and there are security concerns with making the call back, remove
the legacy (pre Gen9) NMI sourcing and the DMI code to determine if
the system had the CRU interface.

commit c42cbe41727a138905a28f8e0b00c147be77ee93 upstream.
This corrects:
commit cce78da76601 ("watchdog: hpwdt: Add check for UEFI bits")
The test on HPE SMBIOS extension type 219 record "Misc Features"
bits for UEFI support is incorrect. The definition of the Misc Features
bits in the HPE SMBIOS OEM Extensions specification (and related
firmware) was changed to use a different pair of bits to
represent UEFI supported. Howerver, a corresponding change
to Linux was missed.
Current code/platform work because the iCRU test is working.
But purpose of cce78da766 is to ensure correct functionality
on future systems where iCRU isn't supported.

commit d64d6c5671db5e693a0caaee79f2571b098749c9 upstream.
This patch fixes regression added by commit d74595278f4ab
("scsi: qla2xxx: Add multiple queue pair functionality.").
When driver is not able to get reqeusted IRQs from the system, driver will
attempt tp clean up memory before failing hardware probe. During this cleanup,
driver assigns NULL value to the pointer which has not been allocated by
driver yet. This results in a NULL pointer access.
Log file will show following message and stack trace
qla2xxx [0000:a3:00.1]-00c7:21: MSI-X: Failed to enable support, giving up -- 32/-1.
qla2xxx [0000:a3:00.1]-0037:21: Falling back-to MSI mode --1.

commit 86755b7a96faed57f910f9e6b8061e019ac1ec08 upstream.
This can happen e.g. during disk cloning.
This is an incomplete fix: it does not catch duplicate UUIDs earlier
when things are still unattached. It does not unregister the device.
Further changes to cope better with this are planned but conflict with
Coly's ongoing improvements to handling device errors. In the meantime,
one can manually stop the device after this has happened.
Attempts to attach a duplicate device result in:
[ 136.372404] loop: module loaded
[ 136.424461] bcache: register_bdev() registered backing device loop0
[ 136.424464] bcache: bch_cached_dev_attach() Tried to attach loop0 but duplicate UUID already attached
My test procedure is:

When registering duplicate cache device in register_cache(), after failure
on calling register_cache_set(), bch_cache_release() will be called, then
bdev will be freed, so bdevname(bdev, name) caused kernel crash.
Since bch_cache_release() will free bdev, so in this patch we make sure
bdev being freed if register_cache() fail, and do not free bdev again in
register_bcache() when register_cache() fail.

commit 590347e4000356f55eb10b03ced2686bd74dab40 upstream.
gcc-6.3 and earlier show a new warning after a seemingly unrelated
change to the arm64 PAGE_KERNEL definition:
In file included from drivers/md/dm-bufio.c:14:0:
drivers/md/dm-bufio.c: In function 'alloc_buffer':
include/linux/sched/mm.h:182:56: warning: 'noio_flag' may be used uninitialized in this function [-Wmaybe-uninitialized]
current->flags = (current->flags & ~PF_MEMALLOC_NOIO) | flags;
^
The same warning happened earlier on linux-3.18 for MIPS and I did a
workaround for that, but now it's come back.
gcc-7 and newer are apparently smart enough to figure this out, and
other architectures don't show it, so the best I could come up with is
to rework the caller slightly in a way that makes it obvious enough to
all arm64 compilers what is happening here.

The slaves and holders link for the hidden gendisks confuse lsblk so that
it errors out on, or doesn't report the nvme multipath devices. Given
that we don't need holder relationships for something that can't even be

commit 1d037577c323e5090ce281e96bc313ab2eee5be2 upstream.
The following commit:
commit aa4d86163e4e ("block: loop: switch to VFS ITER_BVEC")
replaced __do_lo_send_write(), which used ITER_KVEC iterators, with
lo_write_bvec() which uses ITER_BVEC iterators. In this change, though,
the WRITE flag was lost:
- iov_iter_kvec(&from, ITER_KVEC | WRITE, &kvec, 1, len);
+ iov_iter_bvec(&i, ITER_BVEC, bvec, 1, bvec->bv_len);
This flag is necessary for the DAX case because we make decisions based on
whether or not the iterator is a READ or a WRITE in dax_iomap_actor() and
in dax_iomap_rw().
We end up going through this path in configurations where we combine a PMEM
device with 4k sectors, a loopback device and DAX. The consequence of this
missed flag is that what we intend as a write actually turns into a read in
the DAX code, so no data is ever written.
The very simplest test case is to create a loopback device and try and
write a small string to it, then hexdump a few bytes of the device to see
if the write took. Without this patch you read back all zeros, with this
you read back the string you wrote.
For XFS this causes us to fail or panic during the following xfstests:
xfs/074 xfs/078 xfs/216 xfs/217 xfs/250
For ext4 we have a similar issue where writes never happen, but we don't
currently have any xfstests that use loopback and show this issue.
Fix this by restoring the WRITE flag argument to iov_iter_bvec(). This
causes the xfstests to all pass.

commit 5444a992b4a73aa5246a432c482b20b89bce93a5 upstream.
This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed

rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.

rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1
2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:
i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited

commit ea4f7bd2aca9f68470e9aac0fc9432fd180b1fe7 upstream.
If matrix_keypad_stop() is executing and the keypad interrupt is triggered,
disable_row_irqs() may be called by both matrix_keypad_interrupt() and
matrix_keypad_stop() at the same time, causing interrupts to be disabled
twice and the keypad being "stuck" after resuming.
Take lock when setting keypad->stopped to ensure that ISR will not race
with matrix_keypad_stop() disabling interrupts.

commit fc110ebdd014dd1368c98e7685b47789c31fab42 upstream.
The subordinate value indicates the highest bus number which can be
reached downstream though a certain device.
Commit a20c7f36bd3d ("PCI: Do not allocate more buses than available in
parent") ensures that downstream devices cannot assign busnumbers higher
than the upstream device subordinate number, which was indeed illogical.
By default, dw_pcie_setup_rc() inits the Root Complex subordinate to a
value of 0x01.
Due to this combined with above commit, enumeration stops digging deeper
downstream as soon as bus num 0x01 has been assigned, which is always the
case for a bridge device.
This results in all devices behind a bridge bus remaining undetected, as
these would be connected to bus 0x02 or higher.
Fix this by initializing the RC to a subordinate value of 0xff, which is
not altering hardware behaviour in any way, but informs probing function
pci_scan_bridge() later on which reads this value back from register.
The following nasty errors during boot are also fixed by this:
pci_bus 0000:02: busn_res: can not insert [bus 02-ff] under [bus 01] (conflicts with (null) [bus 01])

commit f8bee6135e167f5b35b7789c74c2956dad14d0d5 upstream.
When UVD is in VM mode, there is not uvd handle exchanged,
uvd.handles are always 0. So vcpu_bo always need save,
Otherwise amdgpu driver will fail during suspend/resume.

commit 545b0bcde7fbd3ee408fa842ea0731451dc4bd0a upstream.
Always set the graphics values to the max for the
asic type. E.g., some 1 RB chips are actually 1 RB chips,
others are actually harvested 2 RB chips.

commit caf0a9030d75509f3cacefe466d6d69d26e3dee6 upstream.
There have been many reports of Ellesmere and Baffin systems not being
able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN
bit from VBIOS table. Windows seems to not have this issue.
On some systems we fail to the encoder cap info from VBIOS. In that case
we should default to enabling HDMI6G support.
This was tested by dwagner on

commit a0aaa03062be252aacad60a776f3374dd53e3f98 upstream.
power containment disabled only on Fiji and compute
power profile. It violates PCIe spec and may cause power
supply failed. Enabling it will fix the issue, even the
fix will drop performance of some compute tests.
