I reworked some of the patches, and merged/split them based on feedback from David Mosberger-Tang, and couple others from the list. Summary of changes. - Removed kdb patch that got in by mistake :-( - split migrate_irq.patch to separate the bug fix v.s. feature required for cpu hotplug support. (Thanks to Kanashige-san (fujitsu) for giving me that extra work :-)). - Removed one per-cpu global that was also initialized to 0, which was not necessary. - Removed some hunks that were white space in hotcpu_ia64.patch - Sorted the newly added headers as per David Moshberger's requirements. - Merged the rest of migrate_irq.patch with hotcpu_ia64.patch as it was integral part of the cpu hotplug patches. - arch/ia64/dig/topology.c is added only for non-numa, numa adds it in arch/ia64/mm/numa.c (Probably better to move to a common file in future) Mostly the same, except some minor restructuring and cleanup... Oh.. this time, i have learned to keep the lines together...:-) and not introducing line breaks... (Hopefully) Cheers, Ashok Raj - Linux Core Software Group Name: core_kernel_init.patch Author: Ashok Raj (Intel Corporation) D: This patch changes __init to __devinit to init_idle so that when a new cpu D: arrives, it can call these functions at a later time. --- linux-2.6.5-lhcs-root/init/main.c | 2 +- linux-2.6.5-lhcs-root/kernel/sched.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff -puN kernel/sched.c~core_kernel_init kernel/sched.c --- linux-2.6.5-lhcs/kernel/sched.c~core_kernel_init 2004-04-26 22:14:54.113320301 -0700 +++ linux-2.6.5-lhcs-root/kernel/sched.c 2004-04-26 22:14:54.117226553 -0700 @@ -2657,7 +2657,7 @@ void show_state(void) read_unlock(&tasklist_lock); } -void __init init_idle(task_t *idle, int cpu) +void __devinit init_idle(task_t *idle, int cpu) { runqueue_t *idle_rq = cpu_rq(cpu), *rq = cpu_rq(task_cpu(idle)); unsigned long flags; diff -puN init/main.c~core_kernel_init init/main.c --- linux-2.6.5-lhcs/init/main.c~core_kernel_init 2004-04-26 22:14:54.114296864 -0700 +++ linux-2.6.5-lhcs-root/init/main.c 2004-04-26 22:14:54.124062494 -0700 @@ -181,7 +181,7 @@ EXPORT_SYMBOL(loops_per_jiffy); better than 1% */ #define LPS_PREC 8 -void __init calibrate_delay(void) +void __devinit calibrate_delay(void) { unsigned long ticks, loopbit; int lps_precision = LPS_PREC; _
