From 77a6a22f697bbc59cd434ff999dc34162e240f16 Mon Sep 17 00:00:00 2001 From: Tom 'spot' Callaway Date: Sun, 24 Apr 2005 20:41:45 -0700 Subject: [SPARC]: Missing sparc32 ksyms This patch adds some missing sparc32 ksyms that are needed. Specifically, ___rw_read_enter, ___rw_read_exit, ___rw_write_enter, and sys_close. Signed-off-by: Tom 'spot' Callaway Signed-off-by: David S.

Specifically, add __cpu_data (PER_CPU), cpu_online_map, and phys_cpu_present_map. This patch assumes that the earlier "linux-2.6.11-sparc-fixksyms.patch" is applied, otherwise, it will apply with fuzz. Signed-off-by: Tom 'spot' Callaway Signed-off-by: David S.
