This patch removes all tmem related code and CONFIG_TMEM from the hypervisor. Also remove tmem hypercalls from the default XSM policy. It is written as if tmem is disabled and tmem freeable pages is 0. We will need to keep public/tmem.h around forever to avoid breaking guests. Remove the hypervisor only part and put guest visible part under a xen version check. Take the chance to remove trailing whitespaces.
