From 18cc6757532e3b0e7a569b1631869c812b777196 Mon Sep 17 00:00:00 2001 From: Peter Samuelson Date: Tue, 8 May 2007 23:34:18 -0400 Subject: Input: logips2pp - add type 72 (PS/2 TrackMan Marble) This is purely cosmetic: this is standard 3-button, no wheel or other such features, so it already _worked_ just fine. This patch suppresses a warning about the unknown model, and changes the printk from "Mouse" to "TrackMan".

This is the last remaining slab destructor in the kernel, which we kill off and move the resultant list tracking logic up to the pmb_alloc()/pmb_free() paths. As Christoph Lameter pointed out, it's potentially unsafe to be taking the list lock in the destructor anyways, so this is also more fundamentally correct. With this in place, we're all set for killing off slab destructors from the kernel entirely.

Thus, the monarch cpu would go ahead and boot up the kdump On SN shub2 systems, this out-of-sync situation causes some slave cpus on different nodes to enter POD. This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in the DIE_INIT_MONARCH_PROCESS event to not dump all active stack traces to the console in the case of kdump. I have tested this patch on an SN machine and a HP RX2600.
