Bug description:
Microsoft would like to request the inclusion of commits in all
releases supported on Azure. These commits will enable reporting 4
Kbytes of dmesg information to Hyper-V when Linux takes a panic.
Microsoft would like to get all releases reporting this information,
so that we can automatically get a rich picture of Linux panics in
Azure. This will limit the need get serial console logs or other
steps to manually acquire debug info.
We would like to request the folloiwng commits to enable the
diagnostic/serviceability improvement:

set")

sysctl_record_panic_msg is not set")

crash kernel")

system crash.")
