192ed0da59d0a13f6db0d7924b1cb72ecadcd1e7 is first bad commit commit 192ed0da59d0a13f6db0d7924b1cb72ecadcd1e7 Author: Christoph Lameter <cl@linux-foundation.org> Date: Mon Oct 27 14:45:46 2008 -0500
cpualloc: the allocator The per cpu allocator allows dynamic allocation of memory on all processors simultaneously. A bitmap is used to track used areas. The allocator implements tight packing to reduce the cache footprint and increase speed since cacheline contention is typically not a concern for memory mainly used by a single cpu. Small objects will fill up gaps left by larger allocations that required alignments. The size of the cpu_alloc area can be changed via the percpu=xxx kernel parameter.
