bnxt_open() can fail in this code path, especially on a VF when
it fails to reserve default rings:
bnxt_open()
__bnxt_open_nic()
bnxt_clear_int_mode()
bnxt_init_dflt_ring_mode()
RX rings would be set to 0 when we hit this error path.
It is possible for a subsequent bnxt_open() call to potentially succeed
with a code path like this:
bnxt_open()
bnxt_hwrm_if_change()
bnxt_fw_init_one()
bnxt_fw_init_one_p3()
bnxt_set_dflt_rfs()
bnxt_rfs_capable()
bnxt_hwrm_reserve_rings()
On older chips, RFS is capable if we can reserve the number of vnics that
is equal to RX rings + 1. But since RX rings is still set to 0 in this
code path, we may mistakenly think that RFS is supported for 0 RX rings.
Later, when the default RX rings are reserved and we try to enable
RFS, it would fail and cause bnxt_open() to fail unnecessarily.
We fix this in 2 places. bnxt_rfs_capable() will always return false if
RX rings is not yet set. bnxt_init_dflt_ring_mode() will call
bnxt_set_dflt_rfs() which will always clear the RFS flags if RFS is not
supported.

Most drivers should not have to worry about selecting the right
weight for their NAPI instances and pass NAPI_POLL_WEIGHT.
It'd be best if we didn't require the argument at all and selected
the default internally.
This change prepares the ground for such reshuffling, allowing
for a smooth transition. The following API should remain after
the next release cycle:
netif_napi_add()
netif_napi_add_weight()
netif_napi_add_tx()
netif_napi_add_tx_weight()
Where the _weight() variants take an explicit weight argument.
I opted for a _weight() suffix rather than a __ prefix, because
we use __ in places to mean that caller needs to also issue a
synchronize_net() call.

The AlphaProject AP-SH4A-3A/AP-SH4AD-0A SH boards use IRQ0 for their SMSC
LAN911x Ethernet chip, so the networking on them must have been broken by
commit 965b2aa78f ("net/smsc911x: fix irq resource allocation failure")
which filtered out 0 as well as the negative error codes -- it was kinda
correct at the time, as platform_get_irq() could return 0 on of_irq_get()
failure and on the actual 0 in an IRQ resource. This issue was fixed by
me (back in 2016!), so we should be able to fix this driver to allow IRQ0
usage again...
When merging this to the stable kernels, make sure you also merge commit
e330b9a6bb ("platform: don't return 0 from platform_get_irq[_byname]()

mptcp: Userspace path manager prerequisites
This series builds upon the path manager mode selection changes merged
in 4994d4fa99 ("Merge branch 'mptcp-path-manager-mode-selection'") to
further modify the path manager code in preparation for adding the new
netlink commands to announce/remove advertised addresses and
create/destroy subflows of an MPTCP connection. The third and final
patch series for the userspace path manager will implement those
commands as discussed in
https://lore.kernel.org/netdev/23ff3b49-2563-1874-fa35-3af55d3088e7@linux.intel.com/#r
Patches 1, 5, and 7 remove some internal constraints on path managers
(in general) without changing in-kernel PM behavior.
Patch 2 adds a self test to validate MPTCP address advertisement ack
behavior.
Patches 3, 4, and 6 add new attributes to existing MPTCP netlink events
and track internal state for populating those attributes.

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when
there is an active userspace daemon. If the daemon is restarting or
hasn't loaded yet, the missing echo will cause the peer to retransmit

Current limits on the # of addresses/subflows must apply only to
in-kernel PM managed sockets. Thus this change removes such
restrictions on connections overseen by non-kernel (e.g. userspace)
PMs. This change also ensures that the kernel does not record stats
inside struct mptcp_pm_data updated along kernel code paths when exercised
via non-kernel PMs.
Additionally, address announcements are acknolwedged and subflow
requests are honored only when it's deemed that a userspace path
manager is active at the time.

This verifies that if a filter is set up with the wait killable feature
that it obeys the semantics that non-fatal signals are ignored during
a notification after the notification is received.
Cases tested:
* Non-fatal signal prior to receive
* Non-fatal signal during receive
* Fatal signal after receive
The normal signal handling is tested in user_notification_signal. That
behaviour remains unchanged.
On an unsupported kernel, these tests will immediately bail as it relies
on a new seccomp flag.

This introduces a per-filter flag (SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV)
that makes it so that when notifications are received by the supervisor the
notifying process will transition to wait killable semantics. Although wait
killable isn't a set of semantics formally exposed to userspace, the
concept is searchable. If the notifying process is signaled prior to the
notification being received by the userspace agent, it will be handled as
normal.
One quirk about how this is handled is that the notifying process
only switches to TASK_KILLABLE if it receives a wakeup from either
an addfd or a signal. This is to avoid an unnecessary wakeup of
the notifying task.
The reasons behind switching into wait_killable only after userspace
receives the notification are:
* Avoiding unncessary work - Often, workloads will perform work that they
may abort (request racing comes to mind). This allows for syscalls to be
aborted safely prior to the notification being received by the
supervisor. In this, the supervisor doesn't end up doing work that the
workload does not want to complete anyways.
* Avoiding side effects - We don't want the syscall to be interruptible
once the supervisor starts doing work because it may not be trivial
to reverse the operation. For example, unmounting a file system may
take a long time, and it's hard to rollback, or treat that as
reentrant.
* Avoid breaking runtimes - Various runtimes do not GC when they are
during a syscall (or while running native code that subsequently
calls a syscall). If many notifications are blocked, and not picked
up by the supervisor, this can get the application into a bad state.

KVM regularly introduces new hypercall services to the guests without
any consent from the userspace. This means, the guests can observe
hypercall services in and out as they migrate across various host
kernel versions. This could be a major problem if the guest
discovered a hypercall, started using it, and after getting migrated
to an older kernel realizes that it's no longer available. Depending
on how the guest handles the change, there's a potential chance that
the guest would just panic.
As a result, there's a need for the userspace to elect the services
that it wishes the guest to discover. It can elect these services
based on the kernels spread across its (migration) fleet. To remedy
this, extend the existing firmware pseudo-registers, such as
KVM_REG_ARM_PSCI_VERSION, but by creating a new COPROC register space
for all the hypercall services available.
These firmware registers are categorized based on the service call
owners, but unlike the existing firmware pseudo-registers, they hold
the features supported in the form of a bitmap.
During the VM initialization, the registers are set to upper-limit of
the features supported by the corresponding registers. It's expected
that the VMMs discover the features provided by each register via
GET_ONE_REG, and write back the desired values using SET_ONE_REG.
KVM allows this modification only until the VM has started.
Some of the standard features are not mapped to any bits of the
registers. But since they can recreate the original problem of
making it available without userspace's consent, they need to
be explicitly added to the case-list in
kvm_hvc_call_default_allowed(). Any function-id that's not enabled
via the bitmap, or not listed in kvm_hvc_call_default_allowed, will
be returned as SMCCC_RET_NOT_SUPPORTED to the guest.
Older userspace code can simply ignore the feature and the
hypercall services will be exposed unconditionally to the guests,
thus ensuring backward compatibility.
In this patch, the framework adds the register only for ARM's standard
secure services (owner value 4). Currently, this includes support only
for ARM True Random Number Generator (TRNG) service, with bit-0 of the
register representing mandatory features of v1.0. Other services are
momentarily added in the upcoming patches.

inode_init_security_anon. This name is the key for name based type
transitions on the anon_inode security class on creation. Example:
type=AVC msg=audit(02/16/22 22:02:50.585:216) : avc: granted \
{ create } for pid=2136 comm=mariadbd anonclass=[io_uring] \
scontext=system_u:system_r:mysqld_t:s0 \
tcontext=system_u:system_r:mysqld_iouring_t:s0 tclass=anon_inode
Add a new LSM audit data type holding the inode and the class name.

The arrays for the policy capability names, the initial sid identifiers
and the class and permission names are not changed at runtime. Declare
them const to avoid accidental modification.
Do not override the classmap and the initial sid list in the build time
script genheaders.
Check flose(3) is successful in genheaders.c, otherwise the written data
might be corrupted or incomplete.

Ignore compatible strings for the IPA virt drivers that were removed in
commits 2fb251c265 ("interconnect: qcom: sdx55: Drop IP0
interconnects") and 2f3724930e ("interconnect: qcom: sc7180: Drop IP0
interconnects") so that the sync state logic can kick in again.
Otherwise all the interconnects in the system will stay pegged at max
speeds because 'providers_count' is always going to be one larger than
the number of drivers that will ever probe on sc7180 or sdx55. This
fixes suspend on sc7180 and sdx55 devices when you don't have a
devicetree patch to remove the ipa-virt compatible node.

Configure the touchscreen found on the new display module of the FP2.
To add some detail, FP2 has two different screen/touchscreen variants
("display module"), the old module has Synaptics touchscreen, the new
one this Ilitek touchscreen.
We're only supporting the new display module for now.
