Commit 92563d7a7a5175ef78c4a94ee269b1b455331b4c (cache: Allocate buffers at initialization to detect malloc() failure) split cache_alloc() to cache_init() and cache_alloc(). cache_init() is called in initial(). However, sadly initial_xen() is called before cache_init() and it uses cache_alloc() indirectly which refers to uninitialized structures. Hence, makedumfile run on Xen crash dumps finally fails. This patch moves initial_xen() behind cache_init() call and fixes above mentioned issue.
