From f8b9e5945738d25c04d6735c2a070f574d2b34c5 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Thu, 18 Oct 2007 00:03:50 -0700 Subject: [PARISC] Unbreak processor_probe when we have more than NR_CPUS If we already have NR_CPUS worth of cpus online, we obviously shouldn't be trying to bring up more... Fixes a particularly vexing issue I had when running another machines kernel on my rp3440.
