{u,g}id_valid call {u,g}id_eq, which calls __k{u,g}id_val on both
arguments and compares.  With !CONFIG_MULTIUSER, __k{u,g}id_val return a
constant 0, which makes {u,g}id_valid always return false.  Change
{u,g}id_valid to compare their argument against -1 instead.  That produces
identical results in the normal CONFIG_MULTIUSER=y case, but with
!CONFIG_MULTIUSER will make {u,g}id_valid constant-fold into "return
true;" rather than "return false;".

This fixes uses of devpts without CONFIG_MULTIUSER.

Not all kmem allocations should be accounted to memcg.  The following
patch gives an example when accounting of a certain type of allocations to
memcg can effectively result in a memory leak.  This patch adds the
__GFP_NOACCOUNT flag which if passed to kmalloc and friends will force the
allocation to go through the root cgroup.  It will be used by the next
patch.

Note, since in case of kmemleak enabled each kmalloc implies yet another
allocation from the kmemleak_object cache, we add __GFP_NOACCOUNT to
gfp_kmemleak_mask.

Alternatively, we could introduce a per kmem cache flag disabling
accounting for all allocations of a particular kind, but (a) we would not
be able to bypass accounting for kmalloc then and (b) a kmem cache with
this flag set could not be merged with a kmem cache without this flag,
which would increase the number of global caches and therefore
fragmentation even if the memory cgroup controller is not used.

Despite its generic name, currently __GFP_NOACCOUNT disables accounting
only for kmem allocations while user page allocations are always charged.
To catch abusing of this flag, a warning is issued on an attempt of
passing it to mem_cgroup_try_charge.

Pull libata fixes from Tejun Heo:
 "Rather big for fixes pull.

   - SCC controllers never lived to see the light of the day.  Both
     libata and ide drivers removed.

   - In some configurations, link power management policy changes
     sometimes cause delayed spurious PHY events which can develop into
     noticeable failures.  This has been reported several times over the
     years.  Gabriele's patches suppress PHY events for a while after
     LPM policy changes which should help most of these failures without
     causing too much problem for hotplug use cases.

   - A few controller specific fixes"

[ Hmm.  I don't think removing SSC support is really a "fix", but hey, it
  removes a lot of lines of code.  Which I like.  So ...  good riddance ]
