[PATCH v3 08/16] perf/x86/intel: Use higher-level allocator API

[Brendan Jackman]

The difference between __alloc_pages_node() and alloc_pages_node() is
that the latter allows you to pass NUMA_NO_NODE.

The former is going away and the latter works fine here so switch over.

No functional change intended.
