[PATCH v3 0/3] Account reserved memory when allocating system hash

2016-08-29 Thread Srikar Dronamraju
Fadump kernel reserves large chunks of memory even before the pages are initialised. This could mean memory that corresponds to several nodes might fall in memblock reserved regions. Kernels compiled with CONFIG_DEFERRED_STRUCT_PAGE_INIT will initialise only certain size memory per node. The
