With the virtual mapped linear p2m list the post-init mmu operations must be used for setting up the p2m mappings, as in case of CONFIG_FLATMEM the init routines may trigger BUGs. paging_init() sets up all infrastructure needed to switch to the post-init mmu ops done by xen_post_allocator_init(). With the virtual mapped linear p2m list we need some mmu ops during setup of this list, so we have to switch to the correct mmu ops as soon as possible. The p2m list is usable from the beginning, just expansion requires to have established the new linear mapping. So the call of xen_remap_memory() had to be introduced, but this is not due to the mmu ops requiring this. Summing it up: calling xen_post_allocator_init() not directly after paging_init() was conceptually wrong in the beginning, it just didn't matter up to now as no functions used between the two calls needed some critical mmu ops (e.g. alloc_pte). This has changed now, so I corrected it.
