From 99dd8713306a89f3e106143581244e550e00a644 Mon Sep 17 00:00:00 2001 From: Cliff Wickman Date: Tue, 19 Aug 2008 12:51:59 -0500 Subject: x86, SGI UV: hardcode the TLB flush interrupt system vector The UV TLB shootdown mechanism needs a system interrupt vector. Its vector had been hardcoded as 200, but needs to moved to the reserved system vector range so that it does not collide with some device vector. This is still temporary until dynamic system IRQ allocation is provided. But it will be needed when real UV hardware becomes available and runs 2.6.27.
