While the MAC address the uniq identifier is set to (cf. commit
1425247383 ("HID: nintendo: set controller uniq to MAC")) is certainly
unique, the physical location can be more helpful in user interfaces. The
underlying hid_device already provides a suitable value, so we can simply
reuse this here.

A customer reported a request_socket leak in a Calico cloud environment. We
found that a BPF program was doing a socket lookup with takes a refcnt on
the socket and that it was finding the request_socket but returning the parent
LISTEN socket via sk_to_full_sk() without decrementing the child request socket
1st, resulting in request_sock slab object leak. This patch retains the
existing behaviour of returning full socks to the caller but it also decrements
the child request_socket if one is present before doing so to prevent the leak.
Thanks to Curtis Taylor for all the help in diagnosing and testing this. And
thanks to Antoine Tenart for the reproducer and patch input.
v2 of this patch contains, refactor as per Daniel Borkmann's suggestions to
validate RCU flags on the listen socket so that it balances with bpf_sk_release()
and update comments as per Martin KaFai Lau's suggestion. One small change to
Daniels suggestion, put "sk = sk2" under "if (sk2 != sk)" to avoid an extra
instruction.

None of the sunxi pin controllers have a module reset line. All of the
SoC documentation, where available, agrees. The bits that would be used
for the PIO reset (i.e. matching the order of the clock gate bits) are
always reserved, both in the CCU and in the PRCM. And experiments on
several SoCs, including the A33, confirm that those reserved bits indeed
have no effect.
Let's remove this superfluous code and dependency, and also remove the
include statement that was copied to the other r_pio drivers.

Commit cafe19db77 ("pinctrl: mediatek: Backward compatible to previous
Mediatek's bias-pull usage") allowed the bias-pull-up and bias-pull-down
properties to be used for setting PUPD/R1/R0 type bias on mtk-paris
based SoC's, which was previously only supported by the custom
mediatek,pull-up-adv and mediatek,pull-down-adv properties.
Since the bias-pull-{up,down} properties already have defines associated
thus being more descriptive and is more universal on MediaTek platforms,
and given that there are no mediatek,pull-{up,down}-adv users on mt8192
yet, remove the custom adv properties in favor of the generic ones.
Note that only mediatek,pull-up-adv was merged in the binding, but not
its down counterpart.

When handling userspace MSR filter updates, recompute interception for
possible passthrough MSRs if and only if KVM wants to disabled
interception. If KVM wants to intercept accesses, i.e. the associated
bit is set in vmx->shadow_msr_intercept, then there's no need to set the
intercept again as KVM will intercept the MSR regardless of userspace's
wants.
No functional change intended, the call to vmx_enable_intercept_for_msr()

Wrap the manipulation of @role and the manual mutex_{release,acquire}()
invocations in CONFIG_PROVE_LOCKING=y to squash a clang-15 warning. When
building with -Wunused-but-set-parameter and CONFIG_DEBUG_LOCK_ALLOC=n,
clang-15 seees there's no usage of @role in mutex_lock_killable_nested()
and yells. PROVE_LOCKING selects DEBUG_LOCK_ALLOC, and the only reason
KVM manipulates @role is to make PROVE_LOCKING happy.
To avoid true ugliness, use "i" and "j" to detect the first pass in the
loops; the "idx" field that's used by kvm_for_each_vcpu() is guaranteed
to be '0' on the first pass as it's simply the first entry in the vCPUs
XArray, which is fully KVM controlled. kvm_for_each_vcpu() passes '0'
for xa_for_each_range()'s "start", and xa_for_each_range() will not enter

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

napi_build_skb() reuses NAPI skbuff_head cache in order to save some
cycles on freeing/allocating skbuff_heads on every new Rx or completed
Tx.
Use napi_consume_skb() to feed the cache with skbuff_heads of completed
Tx so it's never empty.

NAPI cache skb_count is being checked twice without condition. Change to
checking the second time only if the first check is run.
