[PATCH 00/30] mm: remove bootmem allocator

Hi, These patches switch early memory management to use memblock directly without any bootmem compatibility wrappers. As the result both bootmem and nobootmem are removed. The patchset survived allyesconfig builds on arm, arm64, i386, mips, nds32, parisc, powerpc, riscv, s390 and x86 and most of
