If rcsi2_code_to_fmt() return NULL, then null pointer dereference occurs
in the next cycle. That should not be possible now but adding checking

xenboot_write_console() is dealing with these quite fine so I don't see

The xen_hvm_early_write() path better wouldn't be taken in this case;
while port 0xE9 can be used, the hypercall path is quite a bit more
efficient. Put that first, as it may also work for DomU-s (see also
xen_raw_console_write()).
While there also bail from the function when the first
domU_write_console() failed - later ones aren't going to succeed.

Decouple XEN_DOM0 from XEN_PV, converting some existing uses of XEN_DOM0
to a new XEN_PV_DOM0. (I'm not convinced all are really / should really
be PV-specific, but for starters I've tried to be conservative.)
For PVH Dom0 the hypervisor populates MADT with only x2APIC entries, so
without x2APIC support enabled in the kernel things aren't going to work
very well. (As opposed, DomU-s would only ever see LAPIC entries in MADT
as of now.) Note that this then requires PVH Dom0 to be 64-bit, as
X86_X2APIC depends on X86_64.
In the course of this xen_running_on_version_or_later() needs to be
available more broadly. Move it from a PV-specific to a generic file,
considering that what it does isn't really PV-specific at all anyway.
Note that xen/interface/version.h cannot be included on its own; in
enlighten.c, which uses SCHEDOP_* anyway, include xen/interface/sched.h
first to resolve the apparently sole missing type (xen_ulong_t).

This reverts commit a77ebdd9f553. It turns out that the VPU domain has no
different requirements, even though the downstream ATF implementation seems
to suggest otherwise. Powering on the domain with the reset asserted works
fine. As the changed sequence has caused sporadic issues with the GPU
domains, just revert the change to go back to the working sequence.

Some board designs don't supply power to all of the power domains,
as they are not used anyways. In that case we must make sure to
not touch those power domains at all, as trying to power up a
domain that has no power supplied to it will obviously end in a
system crash. Allow to disable those domains via the standard DT

The function doesn't use it and all of its callers say in a comment that
their respective arguments are to be non-NULL only in auto-translated
mode. Since xen_remap_domain_mfn_array() isn't supposed to be used by
non-PV, drop the parameter there as well. It was bogusly passed as non-
NULL (PRIV_VMA_LOCKED) by its only caller anyway. For
xen_remap_domain_gfn_range(), otoh, it's not clear at all why this
wouldn't want / might not need to gain auto-translated support down the
road, so the parameter is retained there despite now remaining unused
(and the only caller passing NULL); correct a respective comment as
well.

According to the Realtek propritary driver and the rtw88 driver, the
tx rates of the ack (includes block ack) are initialized with lower
tx rates (no HT rates) which is set by the RRSR register value. In
real cases, ack rate higher than current tx rate could lead to
difficulty for the receiving end to receive management/control frames.
The retransmission rate would be higher then expected when the driver
is acting as receiver and the RSSI is not good.
Cross out higer rates for ack packet before implementing dynamic rrsr
configuration like the commit 4830872685f8 ("rtw88: add dynamic rrsr
configuration").

The usage of fw_crash debugfs is to write 1 to it to trigger fw crash
simulation and to read from it to check the state. When zero is read,
it is supposed to mean fw crash/restart process is done. Then, some
test plans can be designed for crash/restart.
e.g.
step 1. trigger fw crash simulation
step 2. poll the state until zero is read
step 3. check connection by ping test
However, in certain connection cases, triggering fw crash simulation
will take a while. If the state is queried too early before restart
begins processing, it may mistakenly think restart process has been
done. If some tests are started at this time, something unexpected
might happen due to the follow-up restart process.
To avoid that, let fw_crash also show non-zero when a simulation
is still triggering.

Stop the OS from re-discovering multiple LUNs for tape drive and medium
changer.
Duplicate device nodes for Ultrium tape drive and medium changer are being
created.
The Ultrium tape drive is a multi-LUN SCSI target. It presents a LUN for
the tape drive and a 2nd LUN for the medium changer. Our controller FW
lists both LUNs in the RPL results.
As a result, the smartpqi driver exposes both devices to the OS. Then the
OS does its normal device discovery via the SCSI REPORT LUNS command, which
causes it to re-discover both devices a 2nd time, which results in the
duplicate device nodes.

Send a TEST UNIT READY to HBA disks and do not present them to the OS if
0x02/0x04/0x1b (SANITIZE IN PROGRESS) is returned.
During boot-up, some OSes appear to hang when there are one or more disks
undergoing a sanitize operation.
According to SCSI SBC4 specification section 4.11.2 "Commands allowed
during SANITIZE", some SCSI commands are permitted, but read/write
operations are not.
When the OS attempts to read the disk partition table a CHECK CONDITION ASC
0x04 ASCQ 0x1b is returned which causes the OS to retry the read until
SANITIZE has completed. This can take hours.
According to document HPE Smart Storage Administrator User Guide, during
the sanitize erase operation, the drive is unusable. I.e. the expected
behavior for SANITIZE is the that disk remains offline even after SANITIZE
has completed. The customer is expected to re-enable the disk using the
management utility.

Correct kdump hangs when controller is locked up.
There are occasions when a controller reboot (controller soft reset) is
issued when a controller firmware crash dump is in progress.
This leads to incomplete controller firmware crash dump:
- When the controller crash dump is in progress, and a kdump is initiated,
the driver issues inbound doorbell reset to bring back the controller in
SIS mode.
- If the controller is in locked up state, the inbound doorbell reset does
not work causing controller initialization failures. This results in the
driver hanging waiting for SIS mode.
To avoid an incomplete controller crash dump, add in a controller crash
dump handshake:
- Controller will indicate start and end of the controller crash dump by
setting some register bits.
- Driver will look these bits when a kdump is initiated. If a controller
crash dump is in progress, the driver will wait for the controller crash
dump to complete before issuing the controller soft reset then complete
driver initialization.

Commit d39df158518c ("scsi: iscsi: Have abort handler get ref to conn")
added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but
then also changed the handling of the case where we detect an already
completed task where we now end up doing a goto to the common put/cleanup
code. This results in a iscsi_task use after free, because the common
cleanup code will do a put on the iscsi_task.
This reverts the goto and moves the iscsi_get_conn() to after we've checked
if the iscsi_task is valid.

When an FC-GS I/O is aborted by lpfc, the driver requires a node pointer
for a dereference operation. In the abort I/O routine, the driver miscasts
a context pointer to the wrong data type and overwrites a single byte
outside of the allocated space. This miscast is done in the abort I/O
function handler because the handler works on both FC-GS and FC-LS
commands. However, the code neglected to get the correct job location for
the node.
Fix this by acquiring the necessary node pointer from the correct job
structure depending on the I/O type.

It's not holding the lock at this stage and the IRQ "flags" are not correct
so it would restore something bogus. Delete the unlock statement.

pm8001_mpi_get_nvmd_resp() handles a GET_NVMD_DATA response, not a
SET_NVMD_DATA response, as the log statement implies.

Make use of the struct_size() helper instead of an open-coded version, in
order to avoid any potential type mistakes or integer overflows that, in
the worst scenario, could lead to heap overflows.

Many fabric modules provide their own implementation of enable attribute in
tpg.
Provide a way to remove code duplication in the fabric modules and
automatically add "enable" attribute if a fabric module has an
implementation of fabric_enable_tpg().
