  Merge tag 'kvm-x86-fixes-6.16-rc7' of https://github.com/kvm-x86/linux into HEAD (2025-07-17 17:06:13 +0200)

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

* Fix use of u64_replace_bits() in adjusting the guest's view of
  MDCR_EL2.HPMN

RISC-V:

* Fix an issue related to timer cleanup when exiting to user-space

* Fix a race-condition in updating interrupts enabled for the guest
  when IMSIC is hardware-virtualized

x86:

* Reject KVM_SET_TSC_KHZ for guests with a protected TSC (currently only TDX).

* Ensure struct kvm_tdx_capabilities fields that are not explicitly set by KVM
  are zeroed.

Documentation:

* Explain how KVM contributions should be made testable

* Fix a formatting goof in the TDX documentation.
