In the reexport case, nfsd is currently passing along locks with the
reclaim bit set. The client sends a new lock request, which is granted
if there's currently no conflict--even if it's possible a conflicting
lock could have been briefly held in the interim.
We don't currently have any way to safely grant reclaim, so for now
let's just deny them all.
I'm doing this by passing the reclaim bit to nfs and letting it fail the
call, with the idea that eventually the client might be able to do
something more forgiving here.

As in the v4 case, it doesn't work well to block waiting for a lock on
an nfs filesystem.
As in the v4 case, that means we're depending on the client to poll.
It's probably incorrect to depend on that, but I *think* clients do poll
in practice. In any case, it's an improvement over hanging the lockd
thread indefinitely as we currently are.

NFS implements blocking locks by blocking inside its lock method. In
the reexport case, this blocks the nfs server thread, which could lead
to deadlocks since an nfs server thread might be required to unlock the
conflicting lock. It also causes a crash, since the nfs server thread
assumes it can free the lock when its lm_notify lock callback is called.
Ideal would be to make the nfs lock method return without blocking in
this case, but for now it works just not to attempt blocking locks. The
difference is just that the original client will have to poll (as it
does in the v4.0 case) instead of getting a callback when the lock's
available.

This reverts commit fb926032b3209300f9dc454a36b8299582ae545c.
Zhen reports that this commit slows down mq-deadline on a 128 thread
box, going from 258K IOPS to 170-180K. My testing shows that Optane
gen2 IOPS goes from 2.3M IOPS to 1.2M IOPS on a 64 thread box.
Looking in detail at the code, the main culprit here is needing to sum
percpu counters in the dispatch hot path, leading to very high CPU
utilization there. To make matters worse, the code currently needs to
sum 2 percpu counters, and it does so in the most naive way of iterating
possible CPUs _twice_.
Since we're close to release, revert this commit and we can re-do it
with regular per-priority counters instead for the 5.15 kernel.

Pull arm64 fix from Will Deacon:
"We received a report this week that the generic version of
pfn_valid(), which we switched to this merge window in 16c9afc77660

if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr))))

Since the ongoing saga to determine the semantics of pfn_valid() is
unlikely to be resolved this week (does it indicate valid memory, or
just the presence of a struct page, or whether that struct page has
been initialised?), just revert back to our old version of pfn_valid()

The secondary CPU start C routine uses nodat_stack as a
interim stack before finally switching to kernel_stack.
Such scheme is superfluous, since the assembler restart
interrupt handler (that secondary CPU starter is called
from) does not need to use any stack for switching into
DAT mode. Once DAT is on, any stack including virtually-
mapped one could be used.
Avoid the use of nodat_stack and smp_start_secondary()
helper. Instead, initiate kernel_stack directly from
the restart interrupt handler.

The restart interrupt is triggered whenever a secondary CPU is
brought online, a remote function call dispatched from another
CPU or a manual PSW restart is initiated and causes the system
to kdump. The handling routine is always called with DAT turned
off. It then initializes the stack frame and invokes a callback.
The existing callbacks handle DAT as follows:
* __do_restart() and __machine_kexec() turn in on upon entry;
* __ipl_run(), __reipl_run() and __dump_run() do not turn it
right away, but all of them call diag308() - which turns DAT
on, but only if kasan is enabled;
In addition to the described complexity all callbacks (and the
functions they call) should avoid kasan instrumentation while
DAT is off.
This update enables DAT in the assembler restart handler and
relieves any callbacks (which are mostly C functions) from
dealing with DAT altogether.
There are four types of CPU restart that initialize control
registers in different ways:
1. Start of secondary CPU on boot - control registers are
inherited from the IPL CPU;
2. Restart of online CPU - control registers of the CPU being
restarted are kept;
3. Hotplug of offline CPU - control registers are inherited
from the starting CPU;
4. Start of offline CPU triggered by manual PSW restart -
the control registers are read from the absolute lowcore
and contain the boot time IPL CPU values updated with all
follow-up calls of smp_ctl_set_bit() and smp_ctl_clear_bit()
routines;
In first three cases contents of the control registers is the
most recent. In the latter case control registers are good
enough to facilitate successful completion of kdump operation.

If for any reason the interrupt enable for an ap queue fails the
state machine run for the queue returned wrong return codes to the
caller. So the caller assumed interrupt support for this queue in
enabled and thus did not re-establish the high resolution timer used
for polling. In the end this let to a hang for the user space process
waiting "forever" for the reply.
This patch reworks these return codes to return correct indications
for the caller to re-establish the timer when a queue runs without
interrupt support.
Please note that this is fixing a wrong behavior after a first
failure (enable interrupt support for the queue) failed. However,
looks like this occasionally happens on KVM systems.

remove function" from Christophe JAILLET <christophe.jaillet@wanadoo.fr>:
The first 2 patches are sraightforward and look logical to me.
However, the 3rd one in purely speculative. It is based on the fact that a
comment states that we enable some irqs on some slave ports. That said, it writes
0xFF in some registers.
So, I guess that we should disable these irqs when the driver is removed. That
said, writing 0x00 at the same place looks logical to me.
This cis untested and NOT based on any documentation. Just a blind fix.
Review with care.
You'll be warned :)

On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and
lower 16 bits. We need to detect this and apply cu masking to each
SH. The cu mask bits are assigned first to each SE, then to
alternate SHs, then finally to higher CU id. This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.
v2: Use max SH/SE rather than max SH in cu_per_sh.
v3: Fix comment blocks, ensure se_mask is initially zero filled,
and correctly assign se.sh.cu positions to unset bits in cu_mask.

push_rt_task() attempts to move the currently running task away if the
next runnable task has migration disabled and therefore is pinned on the
current CPU.
The current task is retrieved via get_push_task() which only checks for
nr_cpus_allowed == 1, but does not check whether the task has migration
disabled and therefore cannot be moved either. The consequence is a
pointless invocation of the migration thread which correctly observes
that the task cannot be moved.
Return NULL if the task has migration disabled and cannot be moved to
another CPU.

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.
For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.
This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by a spinlock.

When more than one FE is connected to a BE, e.g. in a mixing use case,
the BE can be triggered multiple times when the FE are opened/started
concurrently. This race condition is problematic in the case of
SoundWire BE dailinks, and this is not desirable in a general
case. The code carefully checks when the BE can be stopped or
hw_free'ed, but the trigger code does not use any mutual exclusion.
Fix by using the same spinlock already used to check FE states, and
set the state before the trigger. In case of errors, the initial
state will be restored.
This patch does not change how the triggers are handled, it only makes
sure the states are handled in critical sections.

The irqs are requested in 'wcd9335_setup_irqs()' using a resource managed

'wcd9335_setup_irqs()' requests all what is defined in the 'wcd9335_irqs'

This structure has only one entry for 'WCD9335_IRQ_SLIMBUS'.
So 'devm_request...irq()' + explicit 'free_irq()' would lead to a double

Although we modified the codec shutdown callback to perform
runtime-suspend, it's still not fully effective, as this may be
resumed again at any time later.
For fixing such an unwanted resume, this patch replaces
pm_runtime_suspend() with pm_runtime_force_suspend(), and call
pm_runtime_disable() afterward. It assures to keep the device
suspended.
Also for code simplification, we apply the code unconditionally; when
it's been already suspended, nothing would happen by calls of

Factor out force_sig_seccomp from the seccomp signal generation and
place it in kernel/signal.c. The function force_sig_seccomp takes a
parameter force_coredump to indicate that the sigaction field should
be reset to SIGDFL so that a coredump will be generated when the
signal is delivered.
force_sig_seccomp is then used to replace both seccomp_send_sigsys
and seccomp_init_siginfo.
force_sig_info_to_task gains an extra parameter to force using
the default signal action.
With this change seccomp is no longer a special case and there
becomes exactly one place do_coredump is called from.
Further it no longer becomes necessary for __seccomp_filter
to call do_group_exit.

In the fpsp040 code when copyin or copyout fails call
force_sigsegv(SIGSEGV) instead of do_exit(SIGSEGV).
This solves a couple of problems. Because do_exit embeds the ptrace
stop PTRACE_EVENT_EXIT a complete stack frame needs to be present for
that to work correctly. There is always the information needed for a
ptrace stop where get_signal is called. So exiting with a signal
solves the ptrace issue.
Further exiting with a signal ensures that all of the threads in a
process are killed not just the thread that malfunctioned. Which
avoids confusing userspace.
To make force_sigsegv(SIGSEGV) work in fpsp040_die modify the code to
save all of the registers and jump to ret_from_exception (which
ultimately calls get_signal) after fpsp040_die returns.
v2: Updated the branches to use gas's pseudo ops that automatically
calculate the best branch instruction to use for the purpose.

Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on
To fix this problem, just returns user's PFC config parameter saved in
driver.

The GRO configuration is enabled by default after reset. This
is incorrect and should be restored to the user-configured value.
So this restoration is added during reset initialization.

Currently, the cmd index is obtained in debugfs by comparing file names.
However, this method may cause errors when processing more complex file
names. So, change this method by saving cmd in private data and comparing
it when getting cmd index in debugfs for optimization.

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.
The driver notify netif_carrier_on() before update the link state, when the
bond receive carrier on, will query the speed of the port, if the query
operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.
