The patch titled Subject: ia64: make SPARSEMEM default and disable DISCONTIGMEM has been removed from the -mm tree. Its filename was ia64-make-sparsemem-default-and-disable-discontigmem.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: ia64: make SPARSEMEM default and disable DISCONTIGMEM SPARSEMEM memory model suitable for systems with large holes in their phyiscal memory layout. With SPARSEMEM_VMEMMAP enabled it provides pfn_to_page() and page_to_pfn() as fast as FLATMEM. Make it the default memory model for IA-64 and disable DISCONTIGMEM which is considered obsolete for quite some time.
