In current code process, hyperv data in struct vm_arch is never cleared
during VM shutdown and is retained to next VM launch. As the enabled
bit of hypercall_page msr is not clear, hypercall page might cause fatal
error such as Windows VM BSOD during VM restart and memory
remapping. Hyperv page destory function can ensure hyperv page is
destory during each VM shutdown so hyperv related config such as
hypercall page is established correctly during each VM launch.

Service VM may write 0x6 to port 0xcf9 to trigger a warm reset, but
current hypervisor always performs a cold reset by writing 0xE to CF9.
Hypervisor should reboot the system in the same mode as Service VM
specified. Specific OS features (like linux pstore) requires warm
reset to keep data across reboot.

The behavior of hv console's reboot command (cold reset) remains

After rebooting guest, CPPC initialization failed because _CST and _CPC
missed in DSDT table. When writing _CST and _CPC in DSDT table, it gets
cx_cnt or px_cnt as condition. Getting cx_cnt or px_cnt triggers
the hypercall hcall_get_cpu_pm_state. The hypercall hcall_get_cpu_pm_state
uses VM_CREATED as VM state's condition. While, after rebooting guest,
the VM state is VM_PAUSED when writing _CST and _CPC in DSDT table.
Therefore, changing VM state's condition from VM_CREATED to VM_CREATED or
VM_PAUSED for hcall_get_cpu_pm_state can solve the CPPC initialization
failed issue after rebooting guest.
