Pull more MM updates from Andrew Morton:

 - The series "mm: fixes for fallouts from mem_init() cleanup" from Mike
   Rapoport fixes a couple of issues with the just-merged "arch, mm:
   reduce code duplication in mem_init()" series

 - The series "MAINTAINERS: add my isub-entries to MM part." from Mike
   Rapoport does some maintenance on MAINTAINERS

 - The series "remove tlb_remove_page_ptdesc()" from Qi Zheng does some
   cleanup work to the page mapping code

 - The series "mseal system mappings" from Jeff Xu permits sealing of
   "system mappings", such as vdso, vvar, vvar_vclock, vectors (arm
   compat-mode), sigpage (arm compat-mode)

 - Plus the usual shower of singleton patches
