From a9aa141cfc2e08470bba3b9a8328bc50ac457488 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Thu, 31 Aug 2006 21:27:40 -0700 Subject: [PATCH] [PATCH] x86: increase MAX_MP_BUSSES on default arch Vitezslav Samel reports that an HP DL380 g4 fails using the default arch due to the ISA bus having an ID of 32. It would have worked OK with the generic arch - for some reason the default arch doesn't support as many busses. So bump that up to support 256 busses, but leave it at 32 if we're building a tiny system to save a bit of memory.
