Is hyperv-tlfs.h and friends being deleted? If not, the risk is that someone adds a new #include of it without realizing that it has been superseded by hvhdk.h. Note also that this patch does not apply cleanly to 6.12 rc's, or to current linux-next trees. There's an unrelated #include added to arch/x86/include/asm/kvm_host.h that causes a merge failure in that file.

Michael already mentioned this, I'd also agree that it's better to remove hyperv-tlfs.h entirely since it's been superseded. This looks good to me, I'll wait for v3 addressing the other comments to take a look again. - Easwar <...>

Switch to using hvhdk.h everywhere in the kernel. This header includes all the new Hyper-V headers in include/hyperv, which form a superset of the definitions found in hyperv-tlfs.h. This makes it easier to add new Hyper-V interfaces without being restricted to those in the TLFS doc (reflected in hyperv-tlfs.h). To be more consistent with the original Hyper-V code, the names of some definitions are changed slightly. Update those where needed. hyperv-tlfs.h is no longer included anywhere - hvhdk.h can serve the same role, but with an easier path for adding new definitions.
