For task works we're passing around a bool pointer for whether the
current ring is locked or not, let's wrap it in a structure, that
will make it more opaque preventing abuse and will also help us
to pass more info in the future if needed.

Add support for KASAN in the alloc_caches (apoll and netmsg_cache).
Thus, if something touches the unused caches, it will raise a KASAN
warning/exception.
It poisons the object when the object is put to the cache, and unpoisons
it when the object is gotten or freed.

Having cache entries linked using the hlist format brings no benefit, and
also requires an unnecessary extra pointer address per cache entry.
Use the internal io_wq_work_node single-linked list for the internal
alloc caches (async_msghdr and async_poll)
This is required to be able to use KASAN on cache entries, since we do
not need to touch unused (and poisoned) cache entries when adding more
entries to the list.

The ring mapped provided buffer rings rely on the application allocating
the memory for the ring, and then the kernel will map it. This generally
works fine, but runs into issues on some architectures where we need
to be able to ensure that the kernel and application virtual address for
the ring play nicely together. This at least impacts architectures that
set SHM_COLOUR, but potentially also anyone setting SHMLBA.
To use this variant of ring provided buffers, the application need not
allocate any memory for the ring. Instead the kernel will do so, and
the allocation must subsequently call mmap(2) on the ring with the
offset set to:
IORING_OFF_PBUF_RING | (bgid << IORING_OFF_PBUF_SHIFT)
to get a virtual address for the buffer ring. Normally the application
would allocate a suitable piece of memory (and correctly aligned) and
simply pass that in via io_uring_buf_reg.ring_addr and the kernel would
map it.
Outside of the setup differences, the kernel allocate + user mapped
provided buffer ring works exactly the same.

Some filesystems support multiple threads writing to the same file with
O_DIRECT without requiring exclusive access to it. io_uring can use this
hint to avoid serializing dio writes to this inode, instead allowing them
to run in parallel.
XFS and ext4 both fall into this category, so set the flag for both of
them.

The synchronize_rcu() will be invoked in the perf_pmu_migrate_context(),
when migrating a PMU to a new CPU. However, the current for_each_iommu()
is within RCU read-side critical section.
Two methods were considered to fix the issue.
- Use the dmar_global_lock to replace the RCU read lock when going
through the drhd list. But it triggers a lockdep warning.
- Use the cpuhp_setup_state_multi() to set up a dedicated state for each
IOMMU PMU. The lock can be avoided.
The latter method is implemented in this patch. Since each IOMMU PMU has
a dedicated state, add cpuhp_node and cpu in struct iommu_pmu to track
the state. The state can be dynamically allocated now. Remove the
CPUHP_AP_PERF_X86_IOMMU_PERF_ONLINE.

__enter_from_user_mode() is triggering noinstr warnings with
CONFIG_DEBUG_PREEMPT due to its call of preempt_count_add() via
ct_state().
The preemption disable isn't needed as interrupts are already disabled.
And the context_tracking_enabled() check in ct_state() also isn't needed
as that's already being done by the CT_WARN_ON().
Just use __ct_state() instead.
Fixes the following warnings:
vmlinux.o: warning: objtool: enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section

Pull xfs percpu counter fixes from Darrick Wong:
"We discovered a filesystem summary counter corruption problem that was
traced to cpu hot-remove racing with the call to percpu_counter_sum
that sets the free block count in the superblock when writing it to
disk. The root cause is that percpu_counter_sum doesn't cull from
dying cpus and hence misses those counter values if the cpu shutdown
hooks have not yet run to merge the values.
I'm hoping this is a fairly painless fix to the problem, since the
dying cpu mask should generally be empty. It's been in for-next for a
week without any complaints from the bots.
- Fix a race in the percpu counters summation code where the
summation failed to add in the values for any CPUs that were dying
but not yet dead. This fixes some minor discrepancies and incorrect
assertions when running generic/650"

percpu_counter_sum_all() is now redundant as the race condition it
was invented to handle is now dealt with by percpu_counter_sum()
directly and all users of percpu_counter_sum_all() have been
removed.
Remove it.
This effectively reverts the changes made in f689054aace2
("percpu_counter: add percpu_counter_sum_all interface") except for
the cpumask iteration that fixes percpu_counter_sum() made earlier
in this series.

Split it into two 16-bit integers in struct nvme_tcp_term_pdu

Introduce a core thermal API function, thermal_cooling_device_update(),
for updating the max_state value for a cooling device and rearranging
its statistics in sysfs after a possible change of its ->get_max_state()
callback return value.
That callback is now invoked only once, during cooling device
registration, to populate the max_state field in the cooling device
object, so if its return value changes, it needs to be invoked again
and the new return value needs to be stored as max_state. Moreover,
the statistics presented in sysfs need to be rearranged in general,
because there may not be enough room in them to store data for all
of the possible states (in the case when max_state grows).
The new function takes care of that (and some other minor things
related to it), but some extra locking and lockdep annotations are
added in several places too to protect against crashes in the cases
when the statistics are not present or when a stale max_state value
might be used by sysfs attributes.
Note that the actual user of the new function will be added separately.

Commit 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") moved the sysfb_apply_efi_quirks() call in sysfb_init()
from before the [sysfb_]parse_mode() call to after it.
But sysfb_apply_efi_quirks() modifies the global screen_info struct which
[sysfb_]parse_mode() parses, so doing it later is too late.
This has broken all DMI based quirks for correcting wrong firmware efifb
settings when simpledrm is used.
To fix this move the sysfb_apply_efi_quirks() call back to its old place
and split the new setup of the efifb_fwnode (which requires
the platform_device) into its own function and call that at
the place of the moved sysfb_apply_efi_quirks(pd) calls.

Commit 732ea9db9d8a ("efi: libstub: Move screen_info handling to common
code") reorganized the earlycon handling so that all architectures pass
the screen_info data via a EFI config table instead of populating struct
screen_info directly, as the latter is only possible when the EFI stub
is baked into the kernel (and not into the decompressor).
However, this means that struct screen_info may not have been populated
yet by the time the earlycon probe takes place, and this results in a
non-functional early console.
So let's probe again right after parsing the config tables and
populating struct screen_info. Note that this means that earlycon output
starts a bit later than before, and so it may fail to capture issues
that occur while doing the early EFI initialization.

Currently DMA address width is either read from a RO device register
or force set from the platform data. This breaks DMA when the host DMA
address width is <=32it but the device is >32bit.
Right now the driver may decide to use a 2nd DMA descriptor for
another buffer (happens in case of TSO xmit) assuming that 32bit
addressing is used due to platform configuration but the device will
still use both descriptor addresses as one address.
This can be observed with the Intel EHL platform driver that sets
32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in
case of TCP with iptables NAT configuration on TSO packets.
The logic should be like this: Whatever we do on the host side (memory
allocation GFP flags) should happen with the host DMA width, whenever
we decide how to set addresses on the device registers we must use the
device DMA address width.
This patch renames the platform address width field from addr64 (term

Commit 6930bcbfb6ce dropped the setting of the file_lock range when
decoding a nlm_lock off the wire. This causes the client side grant
callback to miss matching blocks and reject the lock, only to rerequest
it 30s later.
Add a helper function to set the file_lock range from the start and end
values that the protocol uses, and have the nlm_lock decoder call that to
set up the file_lock args properly.
Fixes: 6930bcbfb6ce ("lockd: detect and reject lock arguments that overflow")

The current interconnect provider interface is inherently racy as
providers are expected to be added before being fully initialised.
Specifically, nodes are currently not added and the provider data is not
initialised until after registering the provider which can cause racing
DT lookups to fail.
Add a new provider API which will be used to fix up the interconnect
drivers.
The old API is reimplemented using the new interface and will be removed
once all drivers have been fixed.

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wifi and ipsec.
A little more changes than usual, but it's pretty normal for us that
the rc3/rc4 PRs are oversized as people start testing in earnest.
Possibly an extra boost from people deploying the 6.1 LTS but that's
more of an unscientific hunch.
Current release - regressions:
- phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()
- virtio: vsock: don't use skbuff state to account credit
- virtio: vsock: don't drop skbuff on copy failure
- virtio_net: fix page_to_skb() miscalculating the memory size
Current release - new code bugs:
- eth: correct xdp_features after device reconfig
- wifi: nl80211: fix the puncturing bitmap policy
- net/mlx5e: flower:
- fix raw counter initialization
- fix missing error code
- fix cloned flow attribute
- ipa:
- fix some register validity checks
- fix a surprising number of bad offsets
- kill FILT_ROUT_CACHE_CFG IPA register
Previous releases - regressions:
- tcp: fix bind() conflict check for dual-stack wildcard address
- veth: fix use after free in XDP_REDIRECT when skb headroom is small
- ipv4: fix incorrect table ID in IOCTL path
- ipvlan: make skb->skb_iif track skb->dev for l3s mode
- mptcp:
- fix possible deadlock in subflow_error_report
- fix UaFs when destroying unaccepted and listening sockets
- dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290
Previous releases - always broken:
- tcp: tcp_make_synack() can be called from process context, don't
assume preemption is disabled when updating stats
- netfilter: correct length for loading protocol registers
- virtio_net: add checking sq is full inside xdp xmit
- bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
change
- phy: nxp-c45-tja11xx: fix MII_BASIC_CONFIG_REV bit number
- eth: i40e: fix crash during reboot when adapter is in recovery mode
- eth: ice: avoid deadlock on rtnl lock when auxiliary device
plug/unplug meets bonding
- dsa: mt7530:
- remove now incorrect comment regarding port 5
- set PLL frequency and trgmii only when trgmii is used
- eth: mtk_eth_soc: reset PCS state when changing interface types
Misc:
- ynl: another license adjustment

In my previous commit 0349b8779cc9 ("sched: add new attr TCA_EXT_WARN_MSG
to report tc extact message") I didn't notice the tc action use different
enum with filter. So we can't use TCA_EXT_WARN_MSG directly for tc action.
Let's add a TCA_ROOT_EXT_WARN_MSG for tc action specifically and put this
param before going to the TCA_ACT_TAB nest.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

IP tunnels can apparently update dev->needed_headroom
in their xmit path.
This patch takes care of three tunnels xmit, and also the
core LL_RESERVED_SPACE() and LL_RESERVED_SPACE_EXTRA()
helpers.
More changes might be needed for completeness.

Introduce xdp_set_features_flag utility routine in order to update
dynamically xdp_features according to the dynamic hw configuration via
ethtool (e.g. changing number of hw rx/tx queues).
Add xdp_clear_features_flag() in order to clear all xdp_feature flag.
