From 1bf1eba74ec14bc10966a8ddb23bc8deeb91facd Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 23 Jun 2006 13:15:55 -0600 Subject: [IA64] Format /proc/pal/*/version_info correctly /proc/pal/*/version_info is a bit confusing. HP firmware, at least, reports 07.31 instead of 0.7.31. Also, the comment is out of place; it's an internal detail about the implementation of ia64_pal_version. Since the 2.2 revision of the SDM still states that PAL_VERSION can be called in virtual mode, correct the comment to be more accurate.

Large constants that should be long instead of int. Use NULL instead of 0. Add some missing __iomem casts. Replace a non-C99 structure assignment.

Otherwise FLATMEM has softlockup timeouts. This was boot tested for memory configuration: SPARSEMEM, DISCONTIG+VIRTUAL_MEM_MAP, FLATMEM, FLATMEM+VIRTUAL_MEM_MAP and FLATMEM+VIRTUAL_MEM_MAP with largest memory gap less than LARGE_GAP by using boot parameter "mem=". This was boot tested and "echo m >/proc/sysrq-trigger" output evaluated for : FLATMEM, FLATMEM+VIRTUAL_MEM_MAP, DISCONTIGMEM+VIRTUAL_MEM_MAP and SPARSEMEM.
