[PATCH v0 1/6] x86/hyperv: Rename guest shutdown functions

From: Mukesh Rathor
Date: Wed Sep 03 2025 - 22:11:13 EST


This commit renames hv_machine_crash_shutdown to more appropriate
hv_guest_crash_shutdown and makes it applicable to guests only. This
in preparation for the subsequent hypervisor root/dom0 crash support
patches.
