free_cache_attributes() kfree's: per_cpu(ici_cpuid4_info, cpu)->l3 which is a pointer to memory which was allocated as a block in amd_init_l3_cache(). l3 of a particular cpu points to a part of this memory blob. The part and the rest of the blob are still referenced by other cpus. As far as I can tell from the git history this is a leftover from the conversion from per cpu to node data with commit ba06edb63(x86, cacheinfo: Make L3 cache info per node) and the following commit f658bcfb2(x86, cacheinfo: Cleanup L3 cache index disable support) Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Hans Rosenfeld <hans.rosenfeld@amd.com> Cc: Borislav Petkov <borislav.petkov@amd.com> Cc: Andreas Herrmann <andreas.herrmann3@amd.com> Cc: Mike Travis <travis@sgi.com> Link: http://lkml.kernel.org/r/20110723212626.550539989@linutronix.de Signed-off-by: Ingo Molnar <mingo@elte.hu> |
