Subject[GIT PULL] KVM: x86: Misc changes for 6.16
From
Nothing major, the most interesting change is an optimization to rescan I/O
APIC routes after an EOI VM-Exit when an interception of the EOI was necessary
only because of an in-flight IRQ from the previous routing.

The following changes since commit 45eb29140e68ffe8e93a5471006858a018480a45:

Merge branch 'kvm-fixes-6.15-rc4' into HEAD (2025-04-24 13:39:34 -0400)

KVM: Remove obsolete comment about locking for kvm_io_bus_read/write (2025-05-08 07:16:15 -0700)

----------------------------------------------------------------
KVM x86 misc changes for 6.16:

- Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU IBPB, between
SVM and VMX.

- Advertise support to userspace for WRMSRNS and PREFETCHI.

- Rescan I/O APIC routes after handling EOI that needed to be intercepted due
to the old/previous routing, but not the new/current routing.

- Add a module param to control and enumerate support for device posted
interrupts.

- Misc cleanups.
