LLC-* and node-* events require using the OFFCORE_RESPONSE events
on SandyBridge, but the hw_cache_extra_regs is left uninitialized.
This patch adds the missing extra register configure table for
SandyBridge.

Hi folks,
first I'd like to apologize if the question I'm asking is dumb or a
little bit out of the scope of the list. I've been doing some testing
on setuid functions family lately, and I found a weird behaviour I'm
not able to explain myself. I'm using this small program to try and
switch the ui

issue is still not settled as far as I see.
I need to have the highest memory available for snd/rcv buffer and I
need to know/confirm how much it allocated for my proce
Hi Ben,
Any update about this topic?

Function __mem_cgroup_cancel_local_charge is only called by
mem_cgroup_move_parent. For this case, root memcg has been
checked by mem_cgroup_move_parent. So we needn't check that
again in function __mem_cgroup_cancel_local_charge and just
remove the check in function __mem_cgroup_cancel_local_charg
