[PATCH V2 2/3] powerpc: Poll VPA for topology changes and update NUMA maps

2010-11-09 Thread Jesse Larrew
From: Jesse Larrew This patch sets a timer during boot that will periodically poll the associativity change counters in the VPA. When a change in associativity is detected, it retrieves the new associativity domain information via the H_HOME_NODE_ASSOCIATIVITY hcall and updates the NUMA node m
