Merge tag 'kvm-x86-generic-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM generic changes for 6.17
- Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues related
to private <=> shared memory conversions.
- Drop guest_memfd's .getattr() implementation as the VFS layer will call
generic_fillattr() if inode_operations.getattr is NULL.
