Pull spi updates from Mark Brown:
"Lots of stuff going on in the core for SPI this time around, the two
big changes both being around time in different forms:
- A rework of delay times from Alexandru Ardelean which makes the
ways in which they are specified more consistent between drivers so
that what's available to clients is less dependent on the hardware
implementation.
- Support for PTP timestamping of transfers from Vladimir Oltean,
useful for use with precision clocks with SPI control interfaces.
- Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers"

Pull arm64 updates from Catalin Marinas:
"Apart from the arm64-specific bits (core arch and perf, new arm64
selftests), it touches the generic cow_user_page() (reviewed by
Kirill) together with a macro for x86 to preserve the existing
behaviour on this architecture.
Summary:
- On ARMv8 CPUs without hardware updates of the access flag, avoid
failing cow_user_page() on PFN mappings if the pte is old. The
patches introduce an arch_faults_on_old_pte() macro, defined as
false on x86. When true, cow_user_page() makes the pte young before
attempting __copy_from_user_inatomic().
- Covert the synchronous exception handling paths in
arch/arm64/kernel/entry.S to C.
- FTRACE_WITH_REGS support for arm64.
- ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4
- Several kselftest cases specific to arm64, together with a
MAINTAINERS update for these files (moved to the ARM64 PORT entry).
- Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
instructions under certain conditions.
- Workaround for Cortex-A57 and A72 errata where the CPU may
speculatively execute an AT instruction and associate a VMID with
the wrong guest page tables (corrupting the TLB).
- Perf updates for arm64: additional PMU topologies on HiSilicon
platforms, support for CCN-512 interconnect, AXI ID filtering in
the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.
- GICv3 optimisation to avoid a heavy barrier when accessing the
ICC_PMR_EL1 register.
- ELF HWCAP documentation updates and clean-up.
- SMC calling convention conduit code clean-up.
- KASLR diagnostics printed during boot
- NVIDIA Carmel CPU added to the KPTI whitelist
- Some arm64 mm clean-ups: use generic free_initrd_mem(), remove
stale macro, simplify calculation in __create_pgd_mapping(), typos.
- Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for
endinanness to help with allmodconfig"

Pull device mapper updates from Mike Snitzer:
- Fix DM core to disallow stacking request-based DM on partitions.
- Fix DM raid target to properly resync raidset even if bitmap needed
additional pages.
- Fix DM crypt performance regression due to use of WQ_HIGHPRI for the
IO and crypt workqueues.
- Fix DM integrity metadata layout that was aligned on 128K boundary
rather than the intended 4K boundary (removes 124K of wasted space
for each metadata block).
- Improve the DM thin, cache and clone targets to use spin_lock_irq
rather than spin_lock_irqsave where possible.
- Fix DM thin single thread performance that was lost due to needless
workqueue wakeups.
- Fix DM zoned target performance that was lost due to excessive
backing device checks.

While enqueueing a broadcast skb to port->bc_queue, schedule_work()
is called to add port->bc_work, which processes the skbs in
bc_queue, to "events" work queue. If port->bc_queue is full, the
skb will be discarded and schedule_work(&port->bc_work) won't be
called. However, if port->bc_queue is full and port->bc_work is not
running or pending, port->bc_queue will keep full and schedule_work()
won't be called any more, and all broadcast skbs to macvlan will be
discarded. This case can happen:
macvlan_process_broadcast() is the pending function of port->bc_work,
it moves all the skbs in port->bc_queue to the queue "list", and
processes the skbs in "list". During this, new skbs will keep being
added to port->bc_queue in macvlan_broadcast_enqueue(), and
port->bc_queue may already full when macvlan_process_broadcast()
return. This may happen, especially when there are a lot of real-time
threads and the process is preempted.
Fix this by calling schedule_work(&port->bc_work) even if
port->bc_work is full in macvlan_broadcast_enqueue().

Everytime driver registers with firmware, driver is required to
register for async event notifications as well. These 2 calls
are done using the same firmware command and can be combined.
We are also missing the 2nd step to register for async events
in the suspend/resume path and this will fix it. Prior to this,
we were getting only default notifications.
ULP can register for additional async events for the RDMA driver,
so we add a parameter to the new function to only do step 2 when
it is called from ULP.
