commit b5fc07a5fb56216a49e6c1d0b172d5464d99a89b upstream.
Commit c92a6b5d6335 ("scsi: core: Query VPD size before getting full
page") removed the logic which checks whether a VPD page is present on
the supported pages list before asking for the page itself. That was
done because SPC helpfully states "The Supported VPD Pages VPD page
list may or may not include all the VPD pages that are able to be
returned by the device server". Testing had revealed a few devices
that supported some of the 0xBn pages but didn't actually list them in
page 0.
Julian Sikorski bisected a problem with his drive resetting during
discovery to the commit above. As it turns out, this particular drive
firmware will crash if we attempt to fetch page 0xB9.
Various approaches were attempted to work around this. In the end,
reinstating the logic that consults VPD page 0 before fetching any
other page was the path of least resistance. A firmware update for the
devices which originally compelled us to remove the check has since
been released.

commit 0cab687205986491302cd2e440ef1d253031c221 upstream.
The Linux CXL subsystem is built on the assumption that HPA == SPA.
That is, the host physical address (HPA) the HDM decoder registers are
programmed with are system physical addresses (SPA).
During HDM decoder setup, the DVSEC CXL range registers (cxl-3.1,
8.1.3.8) are checked if the memory is enabled and the CXL range is in
a HPA window that is described in a CFMWS structure of the CXL host
bridge (cxl-3.1, 9.18.1.3).
Now, if the HPA is not an SPA, the CXL range does not match a CFMWS
window and the CXL memory range will be disabled then. The HDM decoder
stops working which causes system memory being disabled and further a
system hang during HDM decoder initialization, typically when a CXL
enabled kernel boots.
Prevent a system hang and do not disable the HDM decoder if the
decoder's CXL range is not found in a CFMWS window.
Note the change only fixes a hardware hang, but does not implement
HPA/SPA translation. Support for this can be added in a follow on
patch series.

commit 82b143aeb169b8b55798d7d2063032e1a6ceeeb0 upstream.
This reverts commit 0921244f6f4f0d05698b953fe632a99b38907226.
It broke CPU hotplugging because it modifies the __cpu_possible_mask
after bootup, so that it will be different than nr_cpu_ids, which
then effictively breaks the workqueue setup code and triggers crashes
when shutting down CPUs at runtime.
Guenter was the first who noticed the wrong values in __cpu_possible_mask,
since the cpumask Kunit tests were failig.
Reverting this commit fixes both issues, but sadly brings back this
uncritical runtime warning:

commit 5ef1dc40ffa6a6cb968b0fdc43c3a61727a9e950 upstream.
The s390 common I/O layer (CIO) returns an unexpected -EBUSY return code
when drivers try to start I/O while a path-verification (PV) process is
pending. This can lead to failed device initialization attempts with
symptoms like broken network connectivity after boot.
Fix this by replacing the -EBUSY return code with a deferred condition
code 1 reply to make path-verification handling consistent from a
driver's point of view.
The problem can be reproduced semi-regularly using the following process,
while repeating steps 2-3 as necessary (example assumes an OSA device
with bus-IDs 0.0.a000-0.0.a002 on CHPID 0.02):
1. echo 0.0.a000,0.0.a001,0.0.a002 >/sys/bus/ccwgroup/drivers/qeth/group
2. echo 0 > /sys/bus/ccwgroup/devices/0.0.a000/online
3. echo 1 > /sys/bus/ccwgroup/devices/0.0.a000/online ; \
echo on > /sys/devices/css0/chp0.02/status
Background information:
The common I/O layer starts path-verification I/Os when it receives
indications about changes in a device path's availability. This occurs
for example when hardware events indicate a change in channel-path
status, or when a manual operation such as a CHPID vary or configure
operation is performed.
If a driver attempts to start I/O while a PV is running, CIO reports a
successful I/O start (ccw_device_start() return code 0). Then, after
completion of PV, CIO synthesizes an interrupt response that indicates
an asynchronous status condition that prevented the start of the I/O
(deferred condition code 1).
If a PV indication arrives while a device is busy with driver-owned I/O,
PV is delayed until after I/O completion was reported to the driver's
interrupt handler. To ensure that PV can be started eventually, CIO
reports a device busy condition (ccw_device_start() return code -EBUSY)
if a driver tries to start another I/O while PV is pending.
In some cases this -EBUSY return code causes device drivers to consider
a device not operational, resulting in failed device initialization.
Note: The code that introduced the problem was added in 2003. Symptoms
started appearing with the following CIO commit that causes a PV
indication when a device is removed from the cio_ignore list after the
associated parent subchannel device was probed, but before online
processing of the CCW device has started:
2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")
During boot, the cio_ignore list is modified by the cio_ignore dracut
module [1] as well as Linux vendor-specific systemd service scripts[2].
When combined, this commit and boot scripts cause a frequent occurrence
of the problem during boot.

[ Upstream commit 7ed4380009e96d9e9c605e12822e987b35b05648 ]
If we are bus manager and the bus has inconsistent gap counts, send a
bus reset immediately instead of trying to read the root node's config
ROM first. Otherwise, we could spend a lot of time trying to read the
config ROM but never succeeding.
This eliminates a 50+ second delay before the FireWire bus is usable after
a newly connected device is powered on in certain circumstances.
The delay occurs if a gap count inconsistency occurs, we are not the root
node, and we become bus manager. One scenario that causes this is with a TI
XIO2213B OHCI, the first time a Sony DSR-25 is powered on after being
connected to the FireWire cable. In this configuration, the Linux box will
not receive the initial PHY configuration packet sent by the DSR-25 as IRM,
resulting in the DSR-25 having a gap count of 44 while the Linux box has a
gap count of 63.
FireWire devices have a gap count parameter, which is set to 63 on power-up
and can be changed with a PHY configuration packet. This determines the
duration of the subaction and arbitration gaps. For reliable communication,
all nodes on a FireWire bus must have the same gap count.
A node may have zero or more of the following roles: root node, bus manager
(BM), isochronous resource manager (IRM), and cycle master. Unless a root
node was forced with a PHY configuration packet, any node might become root
node after a bus reset. Only the root node can become cycle master. If the
root node is not cycle master capable, the BM or IRM should force a change
of root node.
After a bus reset, each node sends a self-ID packet, which contains its
current gap count. A single bus reset does not change the gap count, but
two bus resets in a row will set the gap count to 63. Because a consistent
gap count is required for reliable communication, IEEE 1394a-2000 requires
that the bus manager generate a bus reset if it detects that the gap count
is inconsistent.
When the gap count is inconsistent, build_tree() will notice this after the
self identification process. It will set card->gap_count to the invalid
value 0. If we become bus master, this will force bm_work() to send a bus
reset when it performs gap count optimization.
After a bus reset, there is no bus manager. We will almost always try to
become bus manager. Once we become bus manager, we will first determine
whether the root node is cycle master capable. Then, we will determine if
the gap count should be changed. If either the root node or the gap count
should be changed, we will generate a bus reset.
To determine if the root node is cycle master capable, we read its
configuration ROM. bm_work() will wait until we have finished trying to
read the configuration ROM.
However, an inconsistent gap count can make this take a long time.
read_config_rom() will read the first few quadlets from the config ROM. Due
to the gap count inconsistency, eventually one of the reads will time out.
When read_config_rom() fails, fw_device_init() calls it again until
MAX_RETRIES is reached. This takes 50+ seconds.
Once we give up trying to read the configuration ROM, bm_work() will wake
up, assume that the root node is not cycle master capable, and do a bus
reset. Hopefully, this will resolve the gap count inconsistency.
This change makes bm_work() check for an inconsistent gap count before
waiting for the root node's configuration ROM. If the gap count is
inconsistent, bm_work() will immediately do a bus reset. This eliminates
the 50+ second delay and rapidly brings the bus to a working state.
I considered that if the gap count is inconsistent, a PHY configuration
packet might not be successful, so it could be desirable to skip the PHY
configuration packet before the bus reset in this case. However, IEEE
1394a-2000 and IEEE 1394-2008 say that the bus manager may transmit a PHY
configuration packet before a bus reset when correcting a gap count error.
Since the standard endorses this, I decided it's safe to retain the PHY
configuration packet transmission.
Normally, after a topology change, we will reset the bus a maximum of 5
times to change the root node and perform gap count optimization. However,
if there is a gap count inconsistency, we must always generate a bus reset.
Otherwise the gap count inconsistency will persist and communication will
be unreliable. For that reason, if there is a gap count inconstency, we
generate a bus reset even if we already reached the 5 reset limit.

Currently, coretemp driver supports only 128 cores per package.
This loses some core temperature information on systems that have more
than 128 cores per package.

Enlarge the limitation to 512 because there are platforms with more than
256 cores per package.

[ Upstream commit d6d33f03baa43d763fe094ca926eeae7d3421d07 ]
Since the buffer cache for ntfs3 metadata is not released until the file
system is unmounted, allocating from the movable zone may result in cma
allocation failures. This is due to the page still being used by ntfs3,
leading to migration failures.
To address this, this commit use sb_bread_umovable() instead of
sb_bread(). This change prevents allocation from the movable zone,
ensuring compatibility with scenarios where the buffer head is not
released until unmount. This patch is inspired by commit
a8ac900b8163("ext4: use non-movable memory for the ext4 superblock").
The issue is found when playing video files stored in NTFS on the
Android TV platform. During this process, the media parser reads the
video file, causing ntfs3 to allocate buffer cache from the CMA area.
Subsequently, the hardware decoder attempts to allocate memory from the
same CMA area. However, the page is still in use by ntfs3, resulting in
a migrate failure in alloc_contig_range().
The pinned page and allocating stacktrace reported by page owner shows
below:

Unfortunately reparse attribute is used for many purposes (several dozens).
It is not possible here to know is this name symlink or not.
To get exactly the type of name we should to open inode (read mft).
getattr for opened file (fstat) correctly returns symlink.

Another Fujitsu-related patch.
In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.
i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:3092) not working at all.
So this notebook uses a hid-over-i2c touchpad which is managed by the
i2c_designware input driver. Since you can't find a PS/2 mouse port on this
computer and you can't connect a PS/2 mouse to it even with an official
port replicator I think it's safe to not use the PS/2 mouse port at all.

[ Upstream commit 6430dea07e85958fa87d0276c0c4388dd51e630b ]
In ext4_map_blocks(), if we can't find a range of mapping in the
extents cache, we are calling ext4_ext_map_blocks() to search the real
path and ext4_ext_determine_hole() to determine the hole range. But if
the querying range was partially or completely overlaped by a delalloc
extent, we can't find it in the real extent path, so the returned hole
length could be incorrect.
Fortunately, ext4_ext_put_gap_in_cache() have already handle delalloc
extent, but it searches start from the expanded hole_start, doesn't
start from the querying range, so the delalloc extent found could not be
the one that overlaped the querying range, plus, it also didn't adjust
the hole length. Let's just remove ext4_ext_put_gap_in_cache(), handle
delalloc and insert adjusted hole extent in ext4_ext_determine_hole().

[ Upstream commit 11d4d1dba3315f73d2d1d386f5bf4811a8241d45 ]
With the introduction of SMB2_OP_QUERY_WSL_EA, the client may now send
5 commands in a single compound request in order to query xattrs from
potential WSL reparse points, which should be fine as we currently
allow up to 5 PDUs in a single compound request. However, if
encryption is enabled (e.g. 'seal' mount option) or enforced by the
server, current MAX_COMPOUND(5) won't be enough as we require an extra
PDU for the transform header.
Fix this by increasing MAX_COMPOUND to 7 and, while we're at it, add
an WARN_ON_ONCE() and return -EIO instead of -ENOMEM in case we
attempt to send a compound request that couldn't include the extra
transform header.

[ Upstream commit 4049dc96b8de7aeb3addcea039446e464726a525 ]
When the target executes a disconnect and the host triggers a reconnect
immediately, the reconnect command still finds an existing association.
The reconnect crashes later on because nvmet_fc_delete_target_assoc
blindly removes resources while the reconnect code wants to use it.
To address this, nvmet_fc_find_target_assoc should not be able to
lookup an association which is being removed. The association list
is already under RCU lifetime management, so let's properly use it
and remove the association from the list and wait for a grace period
before cleaning up all. This means we also can drop the RCU management
on the queues, because this is now handled via the association itself.
A second step split the execution context so that the initial disconnect
command can complete without running the reconnect code in the same
context. As usual, this is done by deferring the ->done to a workqueue.
