Adds the Lenovo T580 to the SMBus intertouch list for Synaptics
touchpads. I've tested with this for a week now, and it seems a great
improvement. It's also nice to have the complaint gone from dmesg.

During disk scan and revalidation done with sd_revalidate(), the zones
of a zoned disk are checked using the helper function
blk_revalidate_disk_zones() if a configuration change is detected
(change in the number of zones or zone size). The function
blk_revalidate_disk_zones() issues report_zones calls that are very
large, that is, to obtain zone information for all zones of the disk
with a single command. The size of the report zones command buffer
necessary for such large request generally is lower than the disk
max_hw_sectors and KMALLOC_MAX_SIZE (4MB) and succeeds on boot (no
memory fragmentation), but often fail at run time (e.g. hot-plug
event). This causes the disk revalidation to fail and the disk
capacity to be changed to 0.
This problem can be avoided by using vmalloc() instead of kmalloc() for
the buffer allocation. To limit the amount of memory to be allocated,
this patch also introduces the arbitrary SD_ZBC_REPORT_MAX_ZONES
maximum number of zones to report with a single report zones command.
This limit may be lowered further to satisfy the disk max_hw_sectors
limit. Finally, to ensure that the vmalloc-ed buffer can always be
mapped in a request, the buffer size is further limited to at most
queue_max_segments() pages, allowing successful mapping of the buffer
even in the worst case scenario where none of the buffer pages are
contiguous.

Only GFP_KERNEL and GFP_NOIO are used with blkdev_report_zones(). In
preparation of using vmalloc() for large report buffer and zone array
allocations used by this function, remove its "gfp_t gfp_mask" argument
and rely on the caller context to use memalloc_noio_save/restore() where
necessary (block layer zone revalidation and dm-zoned I/O error path).

GCC v9 emits this warning:
CC drivers/s390/scsi/zfcp_erp.o
drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_action_enqueue':
drivers/s390/scsi/zfcp_erp.c:217:26: warning: 'erp_action' may be used uninitialized in this function [-Wmaybe-uninitialized]
217 | struct zfcp_erp_action *erp_action;
| ^~~~~~~~~~
This is a possible false positive case, as also documented in the GCC
documentations:
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wmaybe-uninitialized
The actual code-sequence is like this:
Various callers can invoke the function below with the argument "want"
being one of:
ZFCP_ERP_ACTION_REOPEN_ADAPTER,
ZFCP_ERP_ACTION_REOPEN_PORT_FORCED,
ZFCP_ERP_ACTION_REOPEN_PORT, or
ZFCP_ERP_ACTION_REOPEN_LUN.
zfcp_erp_action_enqueue(want, ...)
...
need = zfcp_erp_required_act(want, ...)
need = want
...
maybe: need = ZFCP_ERP_ACTION_REOPEN_PORT
maybe: need = ZFCP_ERP_ACTION_REOPEN_ADAPTER
...
return need
...
zfcp_erp_setup_act(need, ...)
struct zfcp_erp_action *erp_action; // <== line 217
...
switch(need) {
case ZFCP_ERP_ACTION_REOPEN_LUN:
...
erp_action = &zfcp_sdev->erp_action;
WARN_ON_ONCE(erp_action->port != port); // <== access
...
break;
case ZFCP_ERP_ACTION_REOPEN_PORT:
case ZFCP_ERP_ACTION_REOPEN_PORT_FORCED:
...
erp_action = &port->erp_action;
WARN_ON_ONCE(erp_action->port != port); // <== access
...
break;
case ZFCP_ERP_ACTION_REOPEN_ADAPTER:
...
erp_action = &adapter->erp_action;
WARN_ON_ONCE(erp_action->port != NULL); // <== access
...
break;
}
...
WARN_ON_ONCE(erp_action->adapter != adapter); // <== access
When zfcp_erp_setup_act() is called, 'need' will never be anything else
than one of the 4 possible enumeration-names that are used in the
switch-case, and 'erp_action' is initialized for every one of them, before
it is used. Thus the warning is a false positive, as documented.
We introduce the extra if{} in the beginning to create an extra code-flow,
so the compiler can be convinced that the switch-case will never see any
other value.
BUG_ON()/BUG() is intentionally not used to not crash anything, should
this ever happen anyway - right now it's impossible, as argued above; and
it doesn't introduce a 'default:' switch-case to retain warnings should
'enum zfcp_erp_act_type' ever be extended and no explicit case be
introduced. See also v5.0 commit 399b6c8bc9f7 ("scsi: zfcp: drop old
default switch case which might paper over missing case").

When tracing instances where we open and close WKA ports, we also pass the
request-ID of the respective FSF command.
But after successfully sending the FSF command we must not use the
request-object anymore, as this might result in an use-after-free (see
"zfcp: fix request object use-after-free in send path causing seqno
errors" ).
To fix this add a new variable that caches the request-ID before sending
the request. This won't change during the hand-off to the FCP channel,
and so it's safe to trace this cached request-ID later, instead of using
the request object.

With a recent change to our send path for FSF commands we introduced a
possible use-after-free of request-objects, that might further lead to
zfcp crafting bad requests, which the FCP channel correctly complains
about with an error (FSF_PROT_SEQ_NUMB_ERROR). This error is then handled
by an adapter-wide recovery.
The following sequence illustrates the possible use-after-free:
Send Path:
int zfcp_fsf_open_port(struct zfcp_erp_action *erp_action)
{
struct zfcp_fsf_req *req;
...
spin_lock_irq(&qdio->req_q_lock);
// ^^^^^^^^^^^^^^^^
// protects QDIO queue during sending
...
req = zfcp_fsf_req_create(qdio,
FSF_QTCB_OPEN_PORT_WITH_DID,
SBAL_SFLAGS0_TYPE_READ,
qdio->adapter->pool.erp_req);
// ^^^^^^^^^^^^^^^^^^^
// allocation of the request-object
...
retval = zfcp_fsf_req_send(req);
...
spin_unlock_irq(&qdio->req_q_lock);
return retval;
}
static int zfcp_fsf_req_send(struct zfcp_fsf_req *req)
{
struct zfcp_adapter *adapter = req->adapter;
struct zfcp_qdio *qdio = adapter->qdio;
...
zfcp_reqlist_add(adapter->req_list, req);
// ^^^^^^^^^^^^^^^^
// add request to our driver-internal hash-table for tracking
// (protected by separate lock req_list->lock)
...
if (zfcp_qdio_send(qdio, &req->qdio_req)) {
// ^^^^^^^^^^^^^^
// hand-off the request to FCP channel;
// the request can complete at any point now
...
}
/* Don't increase for unsolicited status */
if (!zfcp_fsf_req_is_status_read_buffer(req))
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// possible use-after-free
adapter->fsf_req_seq_no++;
// ^^^^^^^^^^^^^^^^
// because of the use-after-free we might
// miss this accounting, and as follow-up
// this results in the FCP channel error
// FSF_PROT_SEQ_NUMB_ERROR
adapter->req_no++;
return 0;
}
static inline bool
zfcp_fsf_req_is_status_read_buffer(struct zfcp_fsf_req *req)
{
return req->qtcb == NULL;
// ^^^^^^^^^
// possible use-after-free
}
Response Path:
void zfcp_fsf_reqid_check(struct zfcp_qdio *qdio, int sbal_idx)
{
...
struct zfcp_fsf_req *fsf_req;
...
for (idx = 0; idx < QDIO_MAX_ELEMENTS_PER_BUFFER; idx++) {
...
fsf_req = zfcp_reqlist_find_rm(adapter->req_list,
req_id);
// ^^^^^^^^^^^^^^^^^^^^
// remove request from our driver-internal
// hash-table (lock req_list->lock)
...
zfcp_fsf_req_complete(fsf_req);
}
}
static void zfcp_fsf_req_complete(struct zfcp_fsf_req *req)
{
...
if (likely(req->status & ZFCP_STATUS_FSFREQ_CLEANUP))
zfcp_fsf_req_free(req);
// ^^^^^^^^^^^^^^^^^
// free memory for request-object
else
complete(&req->completion);
// ^^^^^^^^
// completion notification for code-paths that wait
// synchronous for the completion of the request; in
// those the memory is freed separately
}
The result of the use-after-free only affects the send path, and can not
lead to any data corruption. In case we miss the sequence-number
accounting, because the memory was already re-purposed, the next FSF
command will fail with said FCP channel error, and we will recover the
whole adapter. This causes no additional errors, but it slows down
traffic. There is a slight chance of the same thing happen again
recursively after the adapter recovery, but so far this has not been seen.
This was seen under z/VM, where the send path might run on a virtual CPU
that gets scheduled away by z/VM, while the return path might still run,
and so create the necessary timing. Running with KASAN can also slow down
the kernel sufficiently to run into this user-after-free, and then see the
report by KASAN.
To fix this, simply pull the test for the sequence-number accounting in
front of the hand-off to the FCP channel (this information doesn't change
during hand-off), but leave the sequence-number accounting itself where it
is.
To make future regressions of the same kind less likely, add comments to
all closely related code-paths.

The lpfc_debug_dump_all_queues() function repeatedly calls into
lpfc_debug_dump_qe() which has a temporary 128 byte buffer. This was fine
before the introduction of CONFIG_GCC_PLUGIN_STRUCTLEAK_VERBOSE because
each instance could occupy the same stack slot. However, now they each get
their own copy, which leads to a huge increase in stack usage as seen from
the compiler warning:
drivers/scsi/lpfc/lpfc_debugfs.c: In function 'lpfc_debug_dump_all_queues':
drivers/scsi/lpfc/lpfc_debugfs.c:6474:1: error: the frame size of 1712 bytes is larger than 100 bytes [-Werror=frame-larger-than=]
Avoid this by not marking lpfc_debug_dump_qe() as inline so the compiler
can choose to emit a static version of this function when it's needed or
otherwise silently drop it. As an added benefit, not inlining multiple
copies of this function means we save several kilobytes of .text section,
reducing the file size from 47kb to 43.
It is somewhat unusual to have a function that is static but not inline in
a header file, but this does not cause problems here because it is only
used by other inline functions. It would however seem reasonable to move
all the lpfc_debug_dump_* functions into lpfc_debugfs.c and not mark them
inline as a later cleanup.

Pull SCSI scatter-gather list updates from James Bottomley:
"This topic branch covers a fundamental change in how our sg lists are
allocated to make mq more efficient by reducing the size of the
preallocated sg list.
This necessitates a large number of driver changes because the
previous guarantee that if a driver specified SG_ALL as the size of
its scatter list, it would get a non-chained list and didn't need to
bother with scatterlist iterators is now broken and every driver
*must* use scatterlist iterators.
This was broken out as a separate topic because we need to convert all
the drivers before pulling the trigger and unconverted drivers kept
being found, necessitating a rebase"

Pull SCSI updates from James Bottomley:
"This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,
mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the
removal of the osst driver (I heard from Willem privately that he
would like the driver removed because all his test hardware has
failed). Plus number of minor changes, spelling fixes and other
trivia.
The big merge conflict this time around is the SPDX licence tags.
Following discussion on linux-next, we believe our version to be more
accurate than the one in the tree, so the resolution is to take our
version for all the SPDX conflicts"
Note on the SPDX license tag conversion conflicts: the SCSI tree had
done its own SPDX conversion, which in some cases conflicted with the
treewide ones done by Thomas & co.
In almost all cases, the conflicts were purely syntactic: the SCSI tree
used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
treewide conversion had used the new-style ones ("GPL-2.0-only" and
"GPL-2.0-or-later").
In these cases I picked the new-style one.
In a few cases, the SPDX conversion was actually different, though. As
explained by James above, and in more detail in a pre-pull-request
thread:
"The other problem is actually substantive: In the libsas code Luben
Tuikov originally specified gpl 2.0 only by dint of stating:
* This file is licensed under GPLv2.
In all the libsas files, but then muddied the water by quoting GPLv2
verbatim (which includes the or later than language). So for these
files Christoph did the conversion to v2 only SPDX tags and Thomas
converted to v2 or later tags"
So in those cases, where the spdx tag substantially mattered, I took the
SCSI tree conversion of it, but then also took the opportunity to turn
the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.
Similarly, when there were whitespace differences or other differences
to the comments around the copyright notices, I took the version from
the SCSI tree as being the more specific conversion.
Finally, in the spdx conversions that had no conflicts (because the
treewide ones hadn't been done for those files), I just took the SCSI
tree version as-is, even if it was old-style. The old-style conversions
are perfectly valid, even if the "-only" and "-or-later" versions are
perhaps more descriptive.

In mlx5e_setup_tc "priv" variable is not being used if
CONFIG_MLX5_ESWITCH is off, one way to fix this is to actually use it.
mlx5e_setup_tc_mqprio also needs the "priv" variable and it extracts it
on its own. We can simply pass priv to mlx5e_setup_tc_mqprio instead of
netdev and avoid extracting the priv var, which will also resolve the
compiler warning.

drm/imx: IPUv3 image converter improvements, enable scanout FIFO watermark
- Fix a saturation bit position in the colorspace converter
configuration memory.
- Fully describe colorspace conversions in the API to the imx-media driver.
- Add support for limited range and Rec.709 YUV encoding.
- Enable colorimetry configuration via the media-controller API.
- Enable the double write reduction feature for memory bandwidth savings
when the image converter writes YUV 4:2:0 output.
- Enable a scanout FIFO watermark feature that can increase priority of
scanout read transfers at the memory controller whenever the FIFO runs
low.

the __iter_div_u64_rem() inline function which exists to prevent
exactly that problem.

When CONFIG_DMI is disabled, we only have a tentative declaration,
which causes a warning from clang:
drivers/acpi/blacklist.c:20:35: error: tentative array definition assumed to have one element [-Werror]
static const struct dmi_system_id acpi_rev_dmi_table[] __initconst;
As the variable is not actually used here, hide it entirely
in an #ifdef to shut up the warning.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct virtio_scsi {
...
struct virtio_scsi_vq req_vqs[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(*vscsi) + sizeof(vscsi->req_vqs[0]) * num_queues
with:
struct_size(vscsi, req_vqs, num_queues)
This code was detected with the help of Coccinelle.

[Why]
The drm_audio_component can be used to give pin ELD notifications
directly to the sound driver. This fixes audio endpoints disappearing
due to missing unsolicited notifications.
[How]
Send the notification via the audio component whenever we enable or
disable audio state on a stream. This matches what i915 does with
their drm_audio_component and what Takashi Iwai's proposed hack for
radeon/amdpgu did.
This is a bit delayed in when the notification actually occurs, however.
We wait until after all the programming is complete rather than sending
the notification mid sequence.
Particular care is needed for the get ELD callback since it can happen
outside the locking and fencing DRM does for atomic commits.

[Why]
In order to give pin notifications to the sound driver from DM we need
to know whether audio is enabled on a stream and what pin it's using
from DC.
[How]
Expose the instance via stream status if it's a mapped resource for
the stream. It will be -1 if there's no audio mapped.

The cp hang occurs in OCL conformance test only on supermicro
platform which has 40 cores and the test generates 40 threads.
The root cause is race condition in non-protected flags.
The fix is to add flags of is_evicted and is_active(init_mqd())
into protected area.
