The patch titled Subject: nios2: switch to NO_BOOTMEM has been removed from the -mm tree. Its filename was nios2-switch-to-no_bootmem.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx> Subject: nios2: switch to NO_BOOTMEM Remove bootmem bitmap initialization and replace reserve_bootmem() with memblock_reserve().
