[PATCH V2 0/6] x86/Hyper-V: Panic code path fixes

[ltykernel]

From: Tianyu Lan <Tianyu.Lan@xxxxxxxxxxxxx>

This patchset fixes some issues in the Hyper-V panic code path.
Patch 1 resolves issue that panic system still responses network
packets.
Patch 2-3,5-6 resolves crash enlightenment issues.
Patch 4 is to set crash_kexec_post_notifiers to true for Hyper-V
VM in order to report crash data or kmsg to host before running
kdump kernel.

Tianyu Lan (6):
  x86/Hyper-V: Unload vmbus channel in hv panic callback
  x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump
  x86/Hyper-V: Trigger crash enlightenment only once during  system
    crash.
  x86/Hyper-V: Report crash register data or ksmg before  running crash
    kernel
  x86/Hyper-V: Report crash register data when sysctl_record_panic_msg
    is not set
  x86/Hyper-V: Report crash data in die() when panic_on_oops is set
