This patch allows to call the write() function for synchronous and
isochronous channels with buffers of any size. The AIM simply waits for
data to fill up the MOST buffer object according to the network interface
controller specification for streaming channels, before it submits the
buffer to the HDM.
The new behavior is backward compatible to the old applications, since
all known applications needed to fill the buffer completely anyway.

In the mipsr2_decoder() function, used to emulate pre-MIPSr6
instructions that were removed in MIPSr6, the init_fpu() function is
called if a removed pre-MIPSr6 floating point instruction is the first
floating point instruction used by the task. However, init_fpu()
performs varous actions that rely upon not being migrated. For example
in the most basic case it sets the coprocessor 0 Status.CU1 bit to
enable the FPU & then loads FP register context into the FPU registers.
If the task were to migrate during this time, it may end up attempting
to load FP register context on a different CPU where it hasn't set the
CU1 bit, leading to errors such as:

Erratum A-008585 says that the ARM generic timer counter "has the
potential to contain an erroneous value for a small number of core
clock cycles every time the timer value changes". Accesses to TVAL
(both read and write) are also affected due to the implicit counter
read. Accesses to CVAL are not affected.
The workaround is to reread TVAL and count registers until successive
reads return the same value. Writes to TVAL are replaced with an
equivalent write to CVAL.
The workaround is to reread TVAL and count registers until successive reads
return the same value, and when writing TVAL to retry until counter
reads before and after the write return the same value.
The workaround is enabled if the fsl,erratum-a008585 property is found in
the timer node in the device tree. This can be overridden with the
clocksource.arm_arch_timer.fsl-a008585 boot parameter, which allows KVM
users to enable the workaround until a mechanism is implemented to
automatically communicate this information.
This erratum can be found on LS1043A and LS2080A.

map_processor() checks the cpuid value returned by acpi_map_cpuid() for -1
but acpi_map_cpuid() returns -EINVAL in case of error.
As a consequence the error is ignored and the following access into percpu
data with that negative cpuid results in a boot crash.
This happens always when NR_CPUS/nr_cpu_ids is smaller than the number of
processors listed in the ACPI tables.
Use a proper error check for id < 0 so the function returns instead of
trying to map CPU#(-EINVAL).

A new accessor for gic_write_bpr1 is added to arch_gicv3.h in 4.9,
whilst the CP15 accessors are redifined in a separate branch.
This leads to a horrible clash, where the new accessor ends up with
a crap "asm volatile" definition.
Work around this by carrying our own definition of gic_write_bpr1,
creating a small conflict which will be obvious to resolve.

rxrpc_send_call_packet() is invoking the tx_ack tracepoint before it checks
whether there's an ACK to transmit (another thread may jump in and transmit

something.

When the last packet of data to be transmitted on a call is queued, tx_top
is set and then the RXRPC_CALL_TX_LAST flag is set. Unfortunately, this
leaves a race in the ACK processing side of things because the flag affects
the interpretation of tx_top and also allows us to start receiving reply
data before we've finished transmitting.
To fix this, make the following changes:
(1) rxrpc_queue_packet() now sets a marker in the annotation buffer
instead of setting the RXRPC_CALL_TX_LAST flag.
(2) rxrpc_rotate_tx_window() detects the marker and sets the flag in the
same context as the routines that use it.
(3) rxrpc_end_tx_phase() is simplified to just shift the call state.
The Tx window must have been rotated before calling to discard the
last packet.
(4) rxrpc_receiving_reply() is added to handle the arrival of the first
DATA packet of a reply to a client call (which is an implicit ACK of
the Tx phase).
(5) The last part of rxrpc_input_ack() is reordered to perform Tx
rotation, then soft-ACK application and then to end the phase if we've
rotated the last packet. In the event of a terminal ACK, the soft-ACK
application will be skipped as nAcks should be 0.
(6) rxrpc_input_ackall() now has to rotate as well as ending the phase.
In addition:
(7) Alter the transmit tracepoint to log the rotation of the last packet.
(8) Remove the no-longer relevant queue_reqack tracepoint note. The
ACK-REQUESTED packet header flag is now set as needed when we actually
transmit the packet and may vary by retransmission.

Fix the call timer in the following ways:
(1) If call->resend_at or call->ack_at are before or equal to the current
time, then ignore that timeout.
(2) If call->expire_at is before or equal to the current time, then don't
set the timer at all (possibly we should queue the call).
(3) Don't skip modifying the timer if timer_pending() is true. This
indicates that the timer is working, not that it has expired and is
running/waiting to run its expiry handler.
Also call rxrpc_set_timer() to start the call timer going rather than
calling add_timer().

When rxrpc_input_soft_acks() is parsing the soft-ACKs from an ACK packet,
it updates the Tx packet annotations in the annotation buffer. If a
soft-ACK is an ACK, then we overwrite unack'd, nak'd or to-be-retransmitted
states and that is fine; but if the soft-ACK is an NACK, we overwrite the
to-be-retransmitted with a nak - which isn't.
Instead, we need to let any scheduled retransmission stand if the packet
was NAK'd.
Note that we don't reissue a resend if the annotation is in the
to-be-retransmitted state because someone else must've scheduled the
resend already.

Call traceoff trigger after the event is recorded.
Since current traceoff trigger is called before recording
the event, we can not know what event stopped tracing.
Typical usecase of traceoff/traceon trigger is tracing
function calls and trace events between a pair of events.
For example, trace function calls between syscall entry/exit.
In that case, it is useful if we can see the return code
of the target syscall.

Add set_dev_domain_options() to set PCI domain-specific options as devices
are added. The first usage is to request exclusive userspace control of
PCIe hotplug indicators in VMD domains.
Devices in a VMD domain use PCIe hotplug Attention and Power Indicators in
a non-standard way; tell pciehp to ignore the indicators so userspace can
control them via the sysfs "attention" file.
To determine whether a bus is within a VMD domain, add a bool to the
pci_sysdata structure that the VMD driver sets during initialization.

On some Intel BXT platform, wake-up from suspend-to-idle on pressing
power-button is not working. Its noticed that gpio-keys driver marking the
second level IRQ/power-button as wake capable but Intel pintctrl
driver is missing to mark GPIO chip/controller IRQ which first level IRQ
as wake cable if its GPIO pin IRQ is wakeble. So, though the first level
IRQ gets generated on power-button press, since it is not marked as
wake capable resume/wake-up flow is not happening.
Intel pintctrl/GPIO driver need to mark GPIO chip/controller IRQ (first
level IRQ) as wake capable iff GPIO pin's IRQ (second level IRQ) is marked
as wake cable.

It turns out that for north and southwest communities, they can only
generate GPIO interrupts for lower 8 interrupts (IntSel value). The upper
part (8-15) can only generate GPEs (General Purpose Events).
Now the reason why EC events such as pressing hotkeys does not work if we
mask all the interrupts is that in order to generate either interrupts or
GPEs the INTMASK register must have that particular interrupt unmasked. In
case of GPEs the CPU does not trigger normal interrupt (and thus the GPIO
driver does not see it) but instead it causes SCI (System Control
Interrupt) to be triggered with the GPE in question set.
To make this all work as expected we only add those GPIOs to the IRQ domain
that can actually generate interrupts (IntSel value 0-7) and skip others.

When using GPIO irqchip helpers to setup irqchip for a gpiolib based
driver, it is not possible to select which GPIOs to add to the IRQ domain.
Instead it just adds all GPIOs which is not always desired. For example
there might be GPIOs that for some reason cannot generated normal
interrupts at all.
To support this we add a flag irq_need_valid_mask to struct gpio_chip. When
this flag is set the core allocates irq_valid_mask that holds one bit for
each GPIO the chip has. By default all bits are set but drivers can
manipulate this using set_bit() and clear_bit() accordingly.
Then when gpiochip_irqchip_add() is called, this mask is checked and all
GPIOs with bit is set are added to the IRQ domain created for the GPIO
chip.

Same motivation as in commit 80b48c445797 ("bpf: don't use raw processor
id in generic helper"), but this time for XDP typed programs. Thus, allow
for preemption checks when we have DEBUG_PREEMPT enabled, and otherwise
use the raw variant.

We need to use skb_to_full_sk() helper introduced in commit bd5eb35f16a9
("xfrm: take care of request sockets") as otherwise we miss tcp synack
messages, since ownership is on request socket and therefore it would
miss the sk_fullsock() check. Use skb_to_full_sk() as also done similarly
in the bpf_get_cgroup_classid() helper via 2309236c13fe ("cls_cgroup:
get sk_classid only from full sockets") fix to not let this fall through.
Fixes: 4a482f34afcc ("cgroup: bpf: Add bpf_skb_in_cgroup_proto")

====================
hv_netvsc changes
These are mostly about improving the handling of interaction between
the virtual network device (netvsc) and the SR-IOV VF network device.

Useful for debugging issues with multicast and SR-IOV to keep track
of number of received multicast packets.

Since VF reference is now protected by RCU, no longer need the VF usage
counter and can use device flags to see whether to inject or not.

The vf_netdev pointer in the netvsc device context can simply be protected
by RCU because network device destruction is already RCU synchronized.
