      mm: memcg: move pc lookup point to commit_charge() · ce587e65
      Johannes Weiner authored
      None of the callsites actually need the page_cgroup descriptor
      themselves, so just pass the page and do the look up in there.
      We already had two bugs (6568d4a9 'mm: memcg: update the correct soft
      limit tree during migration' and 'memcg: fix Bad page state after
      replace_page_cache') where the passed page and pc were not referring
      to the same page frame.

      mm: nobootmem: Correct alloc_bootmem semantics. · 4e1c2b28
      David Miller authored
      The comments above __alloc_bootmem_node() claim that the code will
      first try the allocation using 'goal' and if that fails it will
      try again but with the 'goal' requirement dropped.
      Unfortunately, this is not what the code does, so fix it to do so.
      This is important for nobootmem conversions to architectures such
      as sparc where MAX_DMA_ADDRESS is infinity.
      On such architectures all of the allocations done by generic spots,
      such as the sparse-vmemmap implementation, will pass in:
      as the goal, and with the limit given as "-1" this will always fail
      unless we add the appropriate fallback logic here.
