From b4f4372f96e0573d752d9e45beda02fabf716cc8 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 23 Nov 2008 21:55:29 -0800 Subject: sparc64: Make %pil level 15 a pseudo-NMI. So that we can profile code even in a local_irq_disable() section, only write 14 (instead of 15) into the %pil register to disable IRQs. This allows PIL level 15 to serve as a pseudo NMI.
