[Xen-devel] [PATCH 4/4] xen/arm: compile and run libxl/xl



Move tsc, rtc, memmap_limit, localtime and shadow settings from
libxl__build_pre to libxl__arch_domain_create.

Get the console and xenstore pfn's from struct xc_dom_image for
autotranslated guests.

Call xc_dom_gnttab_hvm_seed instead of xc_dom_gnttab_init for
autotranslated guests.
