crash/defs.h
Dave Anderson c5c2bf0240 In collaboration with an update to the /dev/crash kernel driver, fix 
for Linux 4.6 commit a7f8de168ace487fa7b88cb154e413cf40e87fc6, which
allows the ARM64 kernel image to be loaded anywhere in physical
memory.  Without the patch, attempting to run live on an ARM64
Linux 4.6 and later kernel may display the warning message "WARNING:
cannot read linux_banner string", and then fails with the message
"crash: vmlinux and /dev/crash do not match!".  Version 1.3 of the
crash driver is required, which introduces a new ioctl command that
retrieves the ARM64-only "kimage_voffset" value that is required for
virtual-to-physical address translation.
