kexec/kdump for arm64

Hi All,

Just for anyone who might be interested, I've started to do some work on kexec and kdump support for arm64. This work is being done within Linaro, so is tracked by their Jira system:

https://cards.linaro.org/browse/CARD-563

I have these two git repos with my work-in-progress patches:

https://git.linaro.org/gitweb?p=people/geoff/kexec-tools.git

https://git.linaro.org/gitweb?p=people/geoff/linux-kexec.git

As of now, I'm just trying to get the pieces in place for a basic kexec reboot. Kdump and advanced features will come later. Comments or suggestions welcome.
