Lock order reversal between page_alloc_lock and mm_rwlock

ISSUE DESCRIPTION The locks pagealloclock and mmrwlock are not always taken in the same order. This raises the possibility of deadlock. The incorrect order occurs only in the implementation of the deprecated domctl hypercall XENDOMCTLgetmemlist. IMPACT A malicious guest administrator may be able ...
