Most of the modern platforms supported by linux kernel have already been cleaned up of old bootmem allocator by moving to nobootmem interface wrapping up the memblock. This patchset is the first attempt to do the similar improvement for MIPS for UMA systems only. Even though the porting was performed as much careful as possible there still might be problem with support of some platforms, especially Loonson3 or SGI IP27, which perform early memory manager initialization by their self. The patchset is split so individual patch being consistent in functional and buildable ways. But the MIPS early memory manager will work correctly only either with or without the whole set being applied. For the same reason a reviewer should not pay much attention to methods bootmem_init(), arch_mem_init(), paging_init() and mem_init() until they are fully refactored. The patchset is applied on top of kernel v4.9.
