powerpc/pseries/cmm: Use adjust_managed_page_count() insted of totalram_pages_* (287b8977) · Commits · 戴 / test

adjust_managed_page_count() performs a totalram_pages_add(), but also adjusts the managed pages of the zone. Let's use that instead, similar to virtio-balloon. Use it before freeing a page. Signed-off-by:
