Jan Beulich 5d7244e7c9 x86-64: Fix memset() to support sizes of 4Gb and above ... While currently there doesn't appear to be any reachable in-tree case where such large memory blocks may be passed to memset() (alloc_bootmem() being the primary non-reachable one, as it gets called with suitably large sizes in FLATMEM configurations), we have recently hit the problem a second time in our Xen kernels. Rather than working around it a second time, prevent others from falling into the same trap by fixing this long standing limitation.
