Subject: [PATCH v1 0/4]mm: convert totalram_pages, totalhigh_pages and managed pages to atomic

This series convert totalram_pages, totalhigh_pages and
zone->managed_pages to atomic variables.

The patch was comiple tested on x86(x86_64_defconfig & i386_defconfig)
on tip of linux-mmotm. And memory hotplug tested on arm64, but on an
older version of kernel.

Arun KS (4):
  mm: Fix multiple evaluvations of totalram_pages and managed_pages
  mm: Convert zone->managed_pages to atomic variable
  mm: convert totalram_pages and totalhigh_pages variables to atomic
  mm: Remove managed_page_count spinlock
