Merge tag 'irqchip-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip updates from Marc Zyngier:

- Add new infrastructure to stop gpiolib from rewriting irq_chip
structures behind our back. Convert a few of them, but this will
obviously be a long effort.

- A bunch of GICv3 improvements, such as using MMIO-based invalidations
when possible, and reducing the amount of polling we perform when
reconfiguring interrupts.

- Another set of GICv3 improvements for the Pseudo-NMI functionality,
with a nice cleanup making it easy to reason about the various
states we can be in when an NMI fires.

- The usual bunch of misc fixes and minor improvements.

Merge tag 'spi-nor/for-5.19' into mtd/next

SPI NOR core changes:
- Read back written SR value to make sure the write was done correctly.
- Introduce a common function for Read ID that manufacturer drivers can
use to verify the Octal DTR switch worked correctly.
- Add helpers for read/write any register commands so manufacturer
drivers don't open code it every time.
- Clarify rdsr dummy cycles documentation.
- Add debugfs entry to expose internal flash parameters and state.

SPI NOR manufacturer drivers changes:
- Add support for Winbond W25Q512NW-IM, and Eon EN25QH256A.
- Move spi_nor_write_ear() to Winbond module since only Winbond flashes
use it.
- Rework Micron and Cypress Octal DTR enable methods to improve
readability.
- Use the common Read ID function to verify switch to Octal DTR mode for
Micron and Cypress flashes.
- Skip polling status on volatile register writes for Micron and Cypress
flashes since the operation is instant.

KVM: SVM: Use target APIC ID to complete AVIC IRQs when possible

Currently, an AVIC-enabled VM suffers from performance bottleneck
when scaling to large number of vCPUs for I/O intensive workloads.

KVM: SVM: Use target APIC ID to complete AVIC IRQs when possible

Currently, an AVIC-enabled VM suffers from performance bottleneck
when scaling to large number of vCPUs for I/O intensive workloads.

In such case, a vCPU often executes halt instruction to get into idle state
waiting for interrupts, in which KVM would de-schedule the vCPU from
physical CPU.

When AVIC HW tries to deliver interrupt to the halting vCPU, it would
result in AVIC incomplete IPI #vmexit to notify KVM to reschedule
the target vCPU into running state.

Investigation has shown the main hotspot is in the kvm_apic_match_dest()
in the following call stack where it tries to find target vCPUs
corresponding to the information in the ICRH/ICRL registers.

- handle_exit
- svm_invoke_exit_handler
- avic_incomplete_ipi_interception
- kvm_apic_match_dest

However, AVIC provides hints in the #vmexit info, which can be used to
retrieve the destination guest physical APIC ID.

In addition, since QEMU defines guest physical APIC ID to be the same as
vCPU ID, it can be used to quickly identify the target vCPU to deliver IPI,
and avoid the overhead from searching through all vCPUs to match the target
vCPU.
