[PATCH] xen/arm: Reduce redundant clear root pages when teardown p2m

Currently, p2m for a domain will be teardown from two paths: (1) The normal path when a domain is destroyed. (2) The arch_domain_destroy() in the failure path of domain creation. When tearing down p2m from (1), the part to clear and clean the root is only needed to do once rather than for every ca

[PATCH] libxl: abort on memory allocation errors

Use abort() instead of just _exit() in libxl__alloc_failed(). This is more friendly for debugging, as it will trap into debugger, systemd-coredump will collect coredump/backtrace etc. It's much more useful than just "libxl: FATAL ERROR: memory allocation failure (...)" message without context where
