The QoS blocks saved/restored when toggling the PD_USB power domain are
clocked by ACLK_USB. Attempting to access these memory regions without
that clock running will result in an indefinite CPU stall.
The PD_USB node wasn't specifying this clock dependency, resulting in
hangs when trying to toggle the power domain (either on or off), unless
we get "lucky" and have ACLK_USB running for another reason at the time.
This "luck" can result from the bootloader leaving USB powered/clocked,
and if no built-in driver wants USB, Linux will disable the unused
PD+CLK on boot when {pd,clk}_ignore_unused aren't given. This can also
be unlucky because the two cleanup tasks run in parallel and race: if
the CLK is disabled first, the PD deactivation stalls the boot. In any
case, the PD cannot then be reenabled (if e.g. the driver loads later)
once the clock has been stopped.
Fix this by specifying a dependency on ACLK_USB, instead of only
ACLK_USB_ROOT. The child-parent relationship means the former implies
the latter anyway.

This should be a per board property, should not be put in
a soc core dtsi.
And when this property convert from default-sample-phase
in linux-5.7 by commit 8a385eb57296 ("ARM: dts: rockchip: fix
rockchip,default-sample-phase property names"), the emmc
on rk3036 kylin board get a initialising error:

[ 4.676156] mmc1: error -84 whilst initialising MMC card
I think the reason why the emmc on rk3036 kylin board was able
to work before linux-5.7 was that the illegal property was not
correctly identified by the rockchip dw_mmc driver.

Change rxrpc's API such that:
(1) A new function, rxrpc_kernel_lookup_peer(), is provided to look up an
rxrpc_peer record for a remote address and a corresponding function,
rxrpc_kernel_put_peer(), is provided to dispose of it again.
(2) When setting up a call, the rxrpc_peer object used during a call is
now passed in rather than being set up by rxrpc_connect_call(). For
afs, this meenat passing it to rxrpc_kernel_begin_call() rather than
the full address (the service ID then has to be passed in as a
separate parameter).
(3) A new function, rxrpc_kernel_remote_addr(), is added so that afs can
get a pointer to the transport address for display purposed, and
another, rxrpc_kernel_remote_srx(), to gain a pointer to the full
rxrpc address.
(4) The function to retrieve the RTT from a call, rxrpc_kernel_get_srtt(),
is then altered to take a peer. This now returns the RTT or -1 if
there are insufficient samples.
(5) Rename rxrpc_kernel_get_peer() to rxrpc_kernel_call_get_peer().
(6) Provide a new function, rxrpc_kernel_get_peer(), to get a ref on a
peer the caller already has.
This allows the afs filesystem to pin the rxrpc_peer records that it is
using, allowing faster lookups and pointer comparisons rather than
comparing sockaddr_rxrpc contents. It also makes it easier to get hold of
the RTT. The following changes are made to afs:
(1) The addr_list struct's addrs[] elements now hold a peer struct pointer
and a service ID rather than a sockaddr_rxrpc.
(2) When displaying the transport address, rxrpc_kernel_remote_addr() is
used.
(3) The port arg is removed from afs_alloc_addrlist() since it's always
overridden.
(4) afs_merge_fs_addr4() and afs_merge_fs_addr6() do peer lookup and may
now return an error that must be handled.
(5) afs_find_server() now takes a peer pointer to specify the address.
(6) afs_find_server(), afs_compare_fs_alists() and afs_merge_fs_addr[46]{}
now do peer pointer comparison rather than address comparison.

David Howells says:
(3) afs_check_validity().
(4) afs_getattr().
These are both pretty short, so your solution is probably good for them.
That said, afs_vnode_commit_status() can spend a long time under the
write lock - and pretty much every file RPC op returns a status update.
Change these functions to use read_seqbegin(). This simplifies the code
and doesn't change the current behaviour, the "seq" counter is always even
so read_seqbegin_or_lock() can never take the lock.

David Howells says:
(5) afs_find_server().
There could be a lot of servers in the list and each server can have
multiple addresses, so I think this would be better with an exclusive
second pass.
The server list isn't likely to change all that often, but when it does
change, there's a good chance several servers are going to be
added/removed one after the other. Further, this is only going to be
used for incoming cache management/callback requests from the server,
which hopefully aren't going to happen too often - but it is remotely
drivable.
(6) afs_find_server_by_uuid().
Similarly to (5), there could be a lot of servers to search through, but
they are in a tree not a flat list, so it should be faster to process.
Again, it's not likely to change that often and, again, when it does
change it's likely to involve multiple changes. This can be driven
remotely by an incoming cache management request but is mostly going to
be driven by setting up or reconfiguring a volume's server list -
something that also isn't likely to happen often.
Make the "seq" counter odd on the 2nd pass, otherwise read_seqbegin_or_lock()
never takes the lock.

David Howells says:
(2) afs_lookup_volume_rcu().
There can be a lot of volumes known by a system. A thousand would

Pull x86 fixes from Ingo Molnar:
- Fix a secondary CPUs enumeration regression caused by creative MADT
APIC table entries on certain systems.
- Fix a race in the NOP-patcher that can spuriously trigger crashes on
bootup.
- Fix a bootup failure regression caused by the parallel bringup code,
caused by firmware inconsistency between the APIC initialization
states of the boot and secondary CPUs, on certain systems.

Pull backing file updates from Amir Goldstein:
These patches essentially just lift some overlayfs code to common code.
The motivation is to reuse common stacking code for the FUSE passthrough
patches that I am shaping up for upstream. The FUSE passthrough work
will be coming in over the next cycles.
I have been testing those patches with my fuse-backing-fd development
branch for quite some time and I think both you and Miklos gave a
conceptual ACK to some version of this work.

Running N CPU-bound tasks on an N CPUs platform:
- with asymmetric CPU capacity
- not being a DynamIq system (i.e. having a PKG level sched domain
without the SD_SHARE_PKG_RESOURCES flag set)
.. might result in a task placement where two tasks run on a big CPU
and none on a little CPU. This placement could be more optimal by
using all CPUs.
Testing platform:
Juno-r2:
- 2 big CPUs (1-2), maximum capacity of 1024
- 4 little CPUs (0,3-5), maximum capacity of 383
Testing workload ([1]):
Spawn 6 CPU-bound tasks. During the first 100ms (step 1), each tasks
is affine to a CPU, except for:
- one little CPU which is left idle.
- one big CPU which has 2 tasks affine.
After the 100ms (step 2), remove the cpumask affinity.
Behavior before the patch:
During step 2, the load balancer running from the idle CPU tags sched
domains as:
- little CPUs: 'group_has_spare'. Cf. group_has_capacity() and
group_is_overloaded(), 3 CPU-bound tasks run on a 4 CPUs
sched-domain, and the idle CPU provides enough spare capacity
regarding the imbalance_pct
- big CPUs: 'group_overloaded'. Indeed, 3 tasks run on a 2 CPUs
sched-domain, so the following path is used:
group_is_overloaded()
\-if (sgs->sum_nr_running <= sgs->group_weight) return true;
The following path which would change the migration type to
'migrate_task' is not taken:
calculate_imbalance()
\-if (env->idle != CPU_NOT_IDLE && env->imbalance == 0)
as the local group has some spare capacity, so the imbalance
is not 0.
The migration type requested is 'migrate_util' and the busiest
runqueue is the big CPU's runqueue having 2 tasks (each having a
utilization of 512). The idle little CPU cannot pull one of these
task as its capacity is too small for the task. The following path
is used:
detach_tasks()
\-case migrate_util:
\-if (util > env->imbalance) goto next;
After the patch:
As the number of failed balancing attempts grows (with
'nr_balance_failed'), progressively make it easier to migrate
a big task to the idling little CPU. A similar mechanism is
used for the 'migrate_load' migration type.
Improvement:
Running the testing workload [1] with the step 2 representing
a ~10s load for a big CPU:
Before patch: ~19.3s
After patch: ~18s (-6.7%)

With UTIL_EST_FASTUP now being permanent, we can take advantage of the
fact that the ewma jumps directly to a higher utilization at dequeue to
simplify util_est and remove the enqueued field.
