  commit a2d9a6fa1fcd2dfcfa9d1d34998156f9399a3eb2
  Author: Paul Durrant <paul.durrant@citrix.com>
  Date:   Thu Aug 9 10:59:41 2018 +0100
  
      tools/libxenctrl: use new xenforeignmemory API to seed grant table
      
      A previous patch added support for priv-mapping guest resources directly
      (rather than having to foreign-map, which requires P2M modification for
      HVM guests).
      
      This patch makes use of the new API to seed the guest grant table unless
      the underlying infrastructure (i.e. privcmd) doesn't support it, in which
      case the old scheme is used.
      
      NOTE: The call to xc_dom_gnttab_hvm_seed() in hvm_build_set_params() was
            actually unnecessary, as the grant table has already been seeded
            by a prior call to xc_dom_gnttab_init() made by libxl__build_dom().

  commit a2d9a6fa1fcd2dfcfa9d1d34998156f9399a3eb2
  Author: Paul Durrant <paul.durrant@citrix.com>
  Date:   Thu Aug 9 10:59:41 2018 +0100
  
      tools/libxenctrl: use new xenforeignmemory API to seed grant table
      
      A previous patch added support for priv-mapping guest resources directly
      (rather than having to foreign-map, which requires P2M modification for
      HVM guests).
      
      This patch makes use of the new API to seed the guest grant table unless
      the underlying infrastructure (i.e. privcmd) doesn't support it, in which
      case the old scheme is used.
      
      NOTE: The call to xc_dom_gnttab_hvm_seed() in hvm_build_set_params() was
            actually unnecessary, as the grant table has already been seeded
            by a prior call to xc_dom_gnttab_init() made by libxl__build_dom().

      mm/swap.c: flush lru pvecs on compound page arrival
      
      [ Upstream commit 8f182270dfec432e93fae14f9208a6b9af01009f ]
      
      Currently we can have compound pages held on per cpu pagevecs, which
      leads to a lot of memory unavailable for reclaim when needed.  In the
      systems with hundreads of processors it can be GBs of memory.
      
      On of the way of reproducing the problem is to not call munmap
      explicitly on all mapped regions (i.e.  after receiving SIGTERM).  After
      that some pages (with THP enabled also huge pages) may end up on
      lru_add_pvec, example below.
      
        void main() {
        #pragma omp parallel
        {
      	size_t size = 55 * 1000 * 1000; // smaller than  MEM/CPUS
      	void *p = mmap(NULL, size, PROT_READ | PROT_WRITE,
      		MAP_PRIVATE | MAP_ANONYMOUS , -1, 0);
      	if (p != MAP_FAILED)
      		memset(p, 0, size);
      	//munmap(p, size); // uncomment to make the problem go away
        }
        }
      
      When we run it with THP enabled it will leave significant amount of
      memory on lru_add_pvec.  This memory will be not reclaimed if we hit
      OOM, so when we run above program in a loop:
      
      	for i in `seq 100`; do ./a.out; done
      
      many processes (95% in my case) will be killed by OOM.
      
      The primary point of the LRU add cache is to save the zone lru_lock
      contention with a hope that more pages will belong to the same zone and
      so their addition can be batched.  The huge page is already a form of
      batched addition (it will add 512 worth of memory in one go) so skipping
      the batching seems like a safer option when compared to a potential
      excess in the caching which can be quite large and much harder to fix
      because lru_add_drain_all is way to expensive and it is not really clear
      what would be a good moment to call it.
      
      Similarly we can reproduce the problem on lru_deactivate_pvec by adding:
      madvise(p, size, MADV_FREE); after memset.
      
      This patch flushes lru pvecs on compound page arrival making the problem
      less severe - after applying it kill rate of above example drops to 0%,
      due to reducing maximum amount of memory held on pvec from 28MB (with
      THP) to 56kB per CPU.

      mm/swap.c: flush lru pvecs on compound page arrival
      
      [ Upstream commit 8f182270dfec432e93fae14f9208a6b9af01009f ]
      
      Currently we can have compound pages held on per cpu pagevecs, which
      leads to a lot of memory unavailable for reclaim when needed.  In the
      systems with hundreads of processors it can be GBs of memory.
      
      On of the way of reproducing the problem is to not call munmap
      explicitly on all mapped regions (i.e.  after receiving SIGTERM).  After
      that some pages (with THP enabled also huge pages) may end up on
      lru_add_pvec, example below.
      
        void main() {
        #pragma omp parallel
        {
      	size_t size = 55 * 1000 * 1000; // smaller than  MEM/CPUS
      	void *p = mmap(NULL, size, PROT_READ | PROT_WRITE,
      		MAP_PRIVATE | MAP_ANONYMOUS , -1, 0);
      	if (p != MAP_FAILED)
      		memset(p, 0, size);
      	//munmap(p, size); // uncomment to make the problem go away
        }
        }
      
      When we run it with THP enabled it will leave significant amount of
      memory on lru_add_pvec.  This memory will be not reclaimed if we hit
      OOM, so when we run above program in a loop:
      
      	for i in `seq 100`; do ./a.out; done
      
      many processes (95% in my case) will be killed by OOM.
      
      The primary point of the LRU add cache is to save the zone lru_lock
      contention with a hope that more pages will belong to the same zone and
      so their addition can be batched.  The huge page is already a form of
      batched addition (it will add 512 worth of memory in one go) so skipping
      the batching seems like a safer option when compared to a potential
      excess in the caching which can be quite large and much harder to fix
      because lru_add_drain_all is way to expensive and it is not really clear
      what would be a good moment to call it.
      
      Similarly we can reproduce the problem on lru_deactivate_pvec by adding:
      madvise(p, size, MADV_FREE); after memset.
      
      This patch flushes lru pvecs on compound page arrival making the problem
      less severe - after applying it kill rate of above example drops to 0%,
      due to reducing maximum amount of memory held on pvec from 28MB (with
      THP) to 56kB per CPU.
