This reverts commit 1d0403d20f6c281cb3d14c5f1db5317caeec48e9.
Anatoly Pugachev reported that the commit 1d0403d20f6c ("net: set proper
memcg for net_init hooks allocations") is somehow causing the sparc64
VMs failed to boot and the VMs boot fine with that patch reverted. So,
revert the patch for now and later we can debug the issue.

The function __ata_change_queue_depth() uses the helper
ata_scsi_find_dev() to get the ata_device structure of a scsi device and
set that device maximum queue depth. However, when the ata device is
managed by libsas, ata_scsi_find_dev() returns NULL, turning
__ata_change_queue_depth() into a nop, which prevents the user from
setting the maximum queue depth of ATA devices used with libsas based
HBAs.
Fix this by renaming __ata_change_queue_depth() to
ata_change_queue_depth() and adding a pointer to the ata_device
structure of the target device as argument. This pointer is provided by
ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of
a libata managed device and by sas_change_queue_depth() using
sas_to_ata_dev() in the case of a libsas managed ata device.

Pull tty/serial driver fixes from Greg KH:
"Here are some small, and late, serial driver fixes for 6.0-rc7 to
resolve some reported problems.
Included in here are:
- tegra icount accounting fixes, including a framework function that
other drivers will be converted over to using in 6.1-rc1.
- fsl_lpuart reset bugfix
- 8250 omap 485 bugfix
- sifive serial clock bugfix
The last three patches have not shown up in linux-next due to them

Pull driver core fixes from Greg KH:
"Here are two tiny driver core fixes for 6.0-rc7 that resolve some
oft-reported problems.
The first is a revert of the "fw_devlink.strict=1" default option that
we keep trying to enable, but we keep finding platforms that this just
breaks everything on. So again, we need it reverted and hopefully it
can be worked on in future releases.
The second is a sysfs file-size bugfix that resolves an issue that
many people are starting to hit as the fix it is fixing also was
backported to stable kernels. The util-linux developers are starting
to get bugreports about sysfs files that contain no data because of
this problem, and this fix which has been in linux-next in the
bitfield tree for a long time, resolves it. I'm submitting it here as
it needs to be merged for 6.0-final, not for 6.1-rc1.
Both of these have been in linux-next with no reported issues, only
reports were that these fixed problems"

The global rwsem dmar_global_lock was introduced by commit 3a5670e8ac932
("iommu/vt-d: Introduce a rwsem to protect global data structures"). It
is used to protect DMAR related global data from DMAR hotplug operations.
The dmar_global_lock used in the intel_iommu_init() might cause recursive
locking issue, for example, intel_iommu_get_resv_regions() is taking the
dmar_global_lock from within a section where intel_iommu_init() already
holds it via probe_acpi_namespace_devices().
Using dmar_global_lock in intel_iommu_init() could be relaxed since it is
unlikely that any IO board must be hot added before the IOMMU subsystem is
initialized. This eliminates the possible recursive locking issue by moving
down DMAR hotplug support after the IOMMU is initialized and removing the
uses of dmar_global_lock in intel_iommu_init().

Few fixes addressing possible out of bound access violations by
hardening them, incorrect asynchronous resets by restricting them,
incorrect SCMI tracing message format by harmonizing them, missing
kernel-doc in optee transport, missing SCMI PM driver remove
routine by adding it to avoid warning when scmi driver is unloaded
and finally improve checks in the info_get operations.

Commit d4252071b97d ("add barriers to buffer_uptodate and
set_buffer_uptodate") added proper memory barriers to the buffer head
BH_Uptodate bit, so that anybody who tests a buffer for being up-to-date
will be guaranteed to actually see initialized state.
However, that commit didn't _just_ add the memory barrier, it also ended
up dropping the "was it already set" logic that the BUFFER_FNS() macro
had.
That's conceptually the right thing for a generic "this is a memory
barrier" operation, but in the case of the buffer contents, we really
only care about the memory barrier for the _first_ time we set the bit,
in that the only memory ordering protection we need is to avoid anybody
seeing uninitialized memory contents.
Any other access ordering wouldn't be about the BH_Uptodate bit anyway,
and would require some other proper lock (typically BH_Lock or the folio
lock). A reader that races with somebody invalidating the buffer head
isn't an issue wrt the memory ordering, it's a serialization issue.
Now, you'd think that the buffer head operations don't matter in this
day and age (and I certainly thought so), but apparently some loads
still end up being heavy users of buffer heads. In particular, the
kernel test robot reported that not having this bit access optimization
in place caused a noticeable direct IO performance regression on ext4:
fxmark.ssd_ext4_no_jnl_DWTL_54_directio.works/sec -26.5% regression
although you presumably need a fast disk and a lot of cores to actually
notice.

When the RDMA auxiliary driver probes, it sets its profile based on
devlink driverinit value. The latter might not be in sync with FW yet
(In case devlink reload is not performed), thus causing a mismatch
between RDMA driver and FW. This results in the following FW syndrome
when the RDMA driver tries to adjust RoCE state, which fails the probe:
"0xC1F678 | modify_nic_vport_context: roce_en set on a vport that
doesn't support roce"
To prevent this, select the PF profile based on FW RoCE capability
instead of relying on devlink driverinit value.
To provide backward compatibility of the RoCE disable feature, on older
FW's where roce_rw is not set (FW RoCE capability is read-only), keep
the current behavior e.g., rely on devlink driverinit value.
Fixes: fbfa97b4d79f ("net/mlx5: Disable roce at HCA level")

There is a very common pattern of using
debugfs_remove(debufs_lookup(..)) which results in a dentry leak of the
dentry that was looked up. Instead of having to open-code the correct
pattern of calling dput() on the dentry, create
debugfs_lookup_and_remove() to handle this pattern automatically and
properly without any memory leaks.

The spi-mux driver is rather too clever and attempts to resubmit any
message that is submitted to it to the parent controller with some
adjusted callbacks. This does not play at all nicely with the fast
path which now sets flags on the message indicating that it's being
handled through the fast path, we see async messages flagged as being on
the fast path. Ideally the spi-mux code would duplicate the message but
that's rather invasive and a bit fragile in that it relies on the mux
knowing which fields in the message to copy. Instead teach the core
that there are controllers which can't cope with the fast path and have
the mux flag itself as being such a controller, ensuring that messages
going via the mux don't get partially handled via the fast path.
This will reduce the performance of any spi-mux connected device since
we'll now always use the thread for both the actual controller and the
mux controller instead of just the actual controller but given that we
were always hitting the slow path anyway it's hopefully not too much of
an additional cost and it allows us to keep the fast path.

David Howells says:
====================
rxrpc fixes
Here are some fixes for AF_RXRPC:
(1) Fix the handling of ICMP/ICMP6 packets. This is a problem due to
rxrpc being switched to acting as a UDP tunnel, thereby allowing it to
steal the packets before they go through the UDP Rx queue. UDP
tunnels can't get ICMP/ICMP6 packets, however. This patch adds an
additional encap hook so that they can.
(2) Fix the encryption routines in rxkad to handle packets that have more
than three parts correctly. The problem is that ->nr_frags doesn't
count the initial fragment, so the sglist ends up too short.
(3) Fix a problem with destruction of the local endpoint potentially
getting repeated.
(4) Fix the calculation of the time at which to resend.
jiffies_to_usecs() gives microseconds, not nanoseconds.
(5) Fix AFS to work out when callback promises and locks expire based on
the time an op was issued rather than the time the first reply packet
arrives. We don't know how long the server took between calculating
the expiry interval and transmitting the reply.
(6) Given (5), rxrpc_get_reply_time() is no longer used, so remove it.

We got a recent syzbot report [1] showing a possible misuse
of pfmemalloc page status in TCP zerocopy paths.
Indeed, for pages coming from user space or other layers,
using page_is_pfmemalloc() is moot, and possibly could give
false positives.
There has been attempts to make page_is_pfmemalloc() more robust,
but not using it in the first place in this context is probably better,
removing cpu cycles.
Note to stable teams :
You need to backport 84ce071e38a6 ("net: introduce
__skb_fill_page_desc_noacc") as a prereq.
Race is more probable after commit c07aea3ef4d4
("mm: add a signature in struct page") because page_is_pfmemalloc()
is now using low order bit from page->lru.next, which can change
more often than page->index.
Low order bit should never be set for lru.next (when used as an anchor
in LRU list), so KCSAN report is mostly a false positive.
Backporting to older kernel versions seems not necessary.
