  Merge tag 'kvm-riscv-fixes-6.10-2' of https://github.com/kvm-riscv/linux into HEAD (2024-06-21 12:48:44 -0400)

----------------------------------------------------------------
ARM:

* Fix dangling references to a redistributor region if the vgic was
  prematurely destroyed.

* Properly mark FFA buffers as released, ensuring that both parties
  can make forward progress.

x86:

* Allow getting/setting MSRs for SEV-ES guests, if they're using the pre-6.9
  KVM_SEV_ES_INIT API.

* Always sync pending posted interrupts to the IRR prior to IOAPIC
  route updates, so that EOIs are intercepted properly if the old routing
  table requested that.

Generic:

* Avoid __fls(0)

* Fix reference leak on hwpoisoned page

* Fix a race in kvm_vcpu_on_spin() by ensuring loads and stores are atomic.

* Fix bug in __kvm_handle_hva_range() where KVM calls a function pointer
  that was intended to be a marker only (nothing bad happens but kind of
  a mine and also technically undefined behavior)

* Do not bother accounting allocations that are small and freed before
  getting back to userspace.

Selftests:

* Fix compilation for RISC-V.

* Fix a "shift too big" goof in the KVM_SEV_INIT2 selftest.

* Compute the max mappable gfn for KVM selftests on x86 using GuestMaxPhyAddr
  from KVM's supported CPUID (if it's available).
