Pull perf/urgent fix from Arnaldo Carvalho de Melo:
- Add missing initialization of perf_sample.cpumode in synthesized samples,
affects jitdump, records for pre-existing threads and records synthesized
from processor trace data, noticed while testing intel_pt events with
'perf script' (Arnaldo Carvalho de Melo)

A recent change to the mbus driver added a warning printk that
prints a phys_addr_t using the %x format string, which fails in
case we build with 64-bit phys_addr_t:
drivers/bus/mvebu-mbus.c: In function 'mvebu_mbus_get_dram_win_info':
drivers/bus/mvebu-mbus.c:975:9: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'phys_addr_t {aka long long unsigned int}' [-Werror=format=]
This uses the special %pa format string instead, so we always
print the correct type.

There is unexpected gpio interrupt after irq_enable. If not
implemeted gpio_irq_enable callback, irq_enable calls irq_unmask
instead. But if there was interrupt set before the irq_enable,
unmask it may trigger the unexpected interrupt. By implementing
the gpio_irq_enable callback, do interrupt status ack, the issue
has gone.

pinctrl-sun8i-a33.c (and the dts) declare only 2 interrupt banks,
where as the closely related a23 has 3 banks. This matches with the
datasheet for the A33 where only interrupt banks B and G are specified
where as the A23 has banks A, B and G.
However the A33 being the A23 derative it is means that the interrupt
configure/status io-addresses for the 2 banks it has are not changed
from the A23, iow they have the same address as if bank A was still
present. Where as the sunxi pinctrl currently tries to use the A23 bank
A addresses for bank B, since the pinctrl code does not know about the
removed bank A.
Add a irq_bank_base parameter and use this where appropriate to take
the missing bank A into account.
This fixes external interrupts not working on the A33 (tested with
an i2c touchscreen controller which uses an external interrupt).

If pinctrl_provide_dummies() is used unconditionally, then the dummy
state will be used even on DT platforms when the "init" state was
intentionally left out. Instead of "default", the dummy "init" state
will then be used during probe. Thus, when probing an I2C controller on
cold boot, communication triggered by bus notifiers broke because the
pins were not initialized.
Do it like OMAP2: use the dummy state only for non-DT platforms.

Fix support for 16 bit source/dest port matches in ixgbe model.

Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

The ATR code was assuming that it would be able to use tcp_hdr for
every TCP frame that came through. However this isn't the case as it
is possible for a frame to arrive that is TCP but sent through something
like a raw socket. As a result the driver was setting up bad filters in
which tcp_hdr was really pointing to the network header so the data was
all invalid.
In order to correct this I have added a bit of parsing logic that will
determine the TCP header location based off of the network header and
either the offset in the case of the IPv4 header, or a walk through the
IPv6 extension headers until it encounters the header that indicates
IPPROTO_TCP. In addition I have added checks to verify that the lowest
protocol provided is recognized as IPv4 or IPv6 to help mitigate raw
sockets using ETH_P_ALL from having ATR applied to them.

The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR. This way we can avoid
having to do any byte swaps in order to validate the port number.
I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct. This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.
In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read. I also went through and dropped the
NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides
no value as the flag is not evaluated in the Rx path.

commit c9f53e63c208 ("ixgbe: Refactor MAC address configuration code")
introduced code that doesn't set HW register RAR0 to default mac address
but FF:FF:FF:FF:FF:FF. Due to this, ixgbe HW discards all incoming packets
that doesn't have destination mac address equals to FF:FF:FF:FF:FF:FF.
This commit sets RAR0 correctly to default HW mac address.

samples
In 473398a21d28 ("perf tools: Add cpumode to struct perf_sample"), I
missed some places where perf_sample fields are directly initialized in
addition to what is done in perf_evsel__parse_sample(), namely when
synthesizing PERF_RECORD_{MMAP*,COMM,FORK,EXIT} for pre-existing threads
and also in intel_pt and intel_bts when synthesizing events from
processor trace, the jitdump code also was affected, fix it.
The problem was noticed with running:
# perf record -e intel_pt//u true
# perf script
Where the samples wouldn't get resolved because perf_sample.cpumode
would be left as zero, i.e. PERF_RECORD_MISC_CPUMODE_UNKNOWN, not
resolving as kernel, hypervisor or user cpu modes.

The PCI memory windows available in vulcan.dtsi are limited to 128MB
for 32-bit BARs, and 4GB for 64-bit BARs. Given the memory mapped IO
space available in arm64, these windows can be increased substantially
to support more use cases.
The change increases the 32-bit window to 256MB and the 64-bit window
to 128 GB. The firmware on vulcan boards will use these ranges as well.
PCI IO windows are not supported on Vulcan, so remove them instead of
keeping an unused value.

If cpu_name_string() is used in non-atomic context when preemption is
enabled, it can trigger a BUG such as this one:

[<ffffffff80105b84>] resume_userspace_check+0x0/0x10
This is possible because cpu_name_string() is used by __show_regs(),
which is used by both show_regs() and show_registers(). These two
functions are used by various exception handling functions, only some of
which ensure that interrupts or preemption is disabled.
However the following have interrupts explicitly enabled or not
explicitly disabled:
- do_reserved() (irqs enabled)
- do_ade() (irqs not disabled)
This can be hit by setting /sys/kernel/debug/mips/unaligned_action to 2,
and triggering an address error exception, e.g. an unaligned access or
access to kernel segment from user mode.
To fix the above cases, use raw_smp_processor_id() instead. It is
unusual for CPU names to be different in the same system, and even if
they were, its possible the process has migrated between the exception
of interest and the cpu_name_string() call anyway.

remove the usage of removed irq_to_gpio() function. On pre-DB1200
boards, pass the actual carddetect GPIO number instead of the IRQ,
because we need the gpio to actually test card status (inserted or
not) and can get the irq number with gpio_to_irq() instead.
Tested on DB1300 and DB1500, this patch fixes PCMCIA on the DB1500,
which used irq_to_gpio().

A few defconfig updates got dropped on the floor during the merge window,
so I've rounded up the remainder here:
* Fix duplicate definition of MMC_BLOCK_MINORS and bump to 32 for
msm8916
* CPUFreq support for the Juno platform, using the MHU/SCPI interface
* Removal of the default command line, which assumed a console called
ttyAMA0
* Bits and pieces for the Hi6220 (96Boards HiKey)

Commit 1ae1602de0 "configfs: switch ->default groups to a linked list"
left the NULL gps pointer behind after removing the kcalloc() call which
made it non-NULL. It also left the !gps check in place so make_cluster()
now fails with ENOMEM. Remove the remaining uses of the gps variable to
fix that.
