Does it make sense to bring in Linux
include/xen/interface/hvm/start_info.h via QEMU's
include/standard-headers/?
QEMU has a script in scripts/update-linux-header.sh for syncing Linux
headers into include/standard-headers/. This makes it easy to keep
Linux header files up-to-date. We basically treat files in
include/standard-headers/ as auto-generated.
If you define start_info.h yourself without using
include/standard-headers/, then it won't be synced with Linux.
