pda->irqstackptr is allocated whenever a CPU is set online. But it is never freed. This results in a memory leak of 16K for each CPU offline/online cycle. Fix is to allocate pda->irqstackptr only once. Signed-off-by: NAndreas Herrmann <andreas.herrmann3@amd.com> Cc: akpm@linux-foundation.org Signed-off-by: NIngo Molnar <mingo@elte.hu>
