Since the HPB mapping is already reset in ufshpb_init() by setting flag
QUERY_FLAG_IDN_HPB_RESET, there is no need doing so again in
ufshpb_hpb_lu_prepared().

This also resolves the issue where HPB WRITE BUFFER is issued before UAC is
cleared.

I've been doing a lot of iscsi patches because Oracle is paying me to work
on iSCSI again. It was supposed to be temp assignment, but my co-worker
that was working on iscsi moved to a new group so it looks like I'm back on
this code again. After talking to Chris and Lee this patch adds me back as
co-maintainer, so I can help them and people remember to cc me on issues.

We set the qedi_ep state to EP_STATE_OFLDCONN_START when the ep is
created. Then in qedi_set_path we kick off the offload work. If userspace
times out the connection and calls ep_disconnect, qedi will only flush the
offload work if the qedi_ep state has transitioned away from
EP_STATE_OFLDCONN_START. If we can't connect we will not have transitioned
state and will leave the offload work running, and we will free the qedi_ep
from under it.

This patch just has us init the work when we create the ep, then always
flush it.

If a offload driver doesn't use the xmit workqueue, then when we are doing
ep_disconnect libiscsi can still inject PDUs to the driver. This adds a

If a driver raises a connection error before the connection is bound, we
can leave a cleanup_work queued that can later run and disconnect/stop a
connection that is logged in. The problem is that drivers can call
iscsi_conn_error_event for endpoints that are connected but not yet bound
when something like the network port they are using is brought down.
iscsi_cleanup_conn_work_fn will check for this and exit early, but if the
cleanup_work is stuck behind other works, it might not get run until after
userspace has done ep_disconnect. Because the endpoint is not yet bound
there was no way for ep_disconnect to flush the work.

The bug of leaving stop_conns queued was added in:

Commit 23d6fefb ("scsi: iscsi: Fix in-kernel conn failure handling")

and:

Commit 0ab71045 ("scsi: iscsi: Perform connection failure entirely in
kernel space")

was supposed to fix it, but left this case.

This patch moves the conn state check to before we even queue the work so
we can avoid queueing.

If iscsid is doing a stop_conn at the same time the kernel is starting
error recovery we can hit a race that allows the cleanup work to run on a
valid connection. In the race, iscsi_if_stop_conn sees the cleanup bit set,
but it calls flush_work on the clean_work before iscsi_conn_error_event has
queued it. The flush then returns before the queueing and so the
cleanup_work can run later and disconnect/stop a conn while it's in a
connected state.

The patch:

Commit 0ab71045 ("scsi: iscsi: Perform connection failure entirely in
kernel space")

added the late stop_conn call bug originally, and the patch:

Commit 23d6fefb ("scsi: iscsi: Fix in-kernel conn failure handling")

attempted to fix it but only fixed the normal EH case and left the above
race for the iscsid restart case. For the normal EH case we don't hit the
race because we only signal userspace to start recovery after we have done
the queueing, so the flush will always catch the queued work or see it
completed.

For iscsid restart cases like boot, we can hit the race because iscsid will
call down to the kernel before the kernel has signaled any error, so both
code paths can be running at the same time. This adds a lock around the
setting of the cleanup bit and queueing so they happen together.

This patch fixes a bug where when using iSCSI offload we can free an
endpoint while userspace still thinks it's active. That then causes the
endpoint ID to be reused for a new connection's endpoint while userspace
still thinks the ID is for the original connection. Userspace will then end
up disconnecting a running connection's endpoint or trying to bind to
another connection's endpoint.

This bug is a regression added in:

Commit 23d6fefb ("scsi: iscsi: Fix in-kernel conn failure handling")

where we added a in kernel ep_disconnect call to fix a bug in:

Commit 0ab71045 ("scsi: iscsi: Perform connection failure entirely in
kernel space")

where we would call stop_conn without having done ep_disconnect. This early
ep_disconnect call will then free the endpoint and it's ID while userspace
still thinks the ID is valid.

Fix the early release of the ID by having the in kernel recovery code keep
a reference to the endpoint until userspace has called into the kernel to
finish cleaning up the endpoint/connection. It requires the previous commit
"scsi: iscsi: Release endpoint ID when its freed" which moved the freeing
of the ID until when the endpoint is released.

When userspace restarts during boot or upgrades it won't know about the
offload driver's endpoint and connection mappings. iscsid will start by
cleaning up the old session by doing a stop_conn call. Later, if we are
able to create a new connection, we clean up the old endpoint during the
binding stage. The problem is that if we do stop_conn before doing the
ep_disconnect call offload, drivers can still be executing I/O. We then
might free tasks from the under the card/driver.

This moves the ep_disconnect call to before we do the stop_conn call for
this case. It will then work and look like a normal recovery/cleanup
procedure from the driver's point of view.

   - Handle supervisor states correctly in the FPU/XSTATE code so it
     takes the feature set of the fpstate buffer into account. The
     feature sets can differ between host and guest buffers. Guest
     buffers do not contain supervisor states. So far this was not an
     issue, but with enabling PASID it needs to be handled in the buffer
     offset calculation and in the permission bitmaps.

   - Avoid a gazillion of repeated CPUID invocations in by caching the
     values early in the FPU/XSTATE code.

   - Enable CONFIG_WERROR in x86 defconfig.

   - Make the X86 defconfigs more useful by adapting them to Y2022
     reality"

This reverts commit 7dabfa2b. There are
multiple reports that this breaks boot on various systems. The common
theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.

Pull more perf tools updates from Arnaldo Carvalho de Melo:

 - Avoid SEGV if core.cpus isn't set in 'perf stat'.

 - Stop depending on .git files for building PERF-VERSION-FILE, used in
   'perf --version', fixing some perf tools build scenarios.

 - Convert tracepoint.py example to python3.

 - Update UAPI header copies from the kernel sources: socket,
   mman-common, msr-index, KVM, i915 and cpufeatures.

 - Update copy of libbpf's hashmap.c.

 - Directly return instead of using local ret variable in
   evlist__create_syswide_maps(), found by coccinelle.
