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.
