[PATCH] cpu hoptlug: avoid usage of smp_processor_id() in preemptible code

2005-11-07T15:53:29Z

Replace smp_processor_id() with any_online_cpu(cpu_online_map) in order to avoid lots of "BUG: using smp_processor_id() in preemptible [00000001] code:..." messages in case taking a cpu online fails. All the traces start at the last notifier_call_chain(...) in kernel/cpu.c. Since we hold the cpu_control semaphore it shouldn't be any problem to access cpu_online_map. The reason why cpu_up failed is simply that the cpu that was supposed to be taken online wasn't even there. That is because on s390 we never know when a new cpu comes and therefore cpu_possible_map consists of only ones and doesn't reflect reality.

[PATCH] revert bogus softirq changes

2005-07-30T17:49:59Z

This snuck in with an x86_64 change. Thanks to Richard Purdie for spotting it. Cc: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] x86_64: Switch to the interrupt stack when running a softirq in local_bh_enable()

2005-07-29T04:46:02Z

This avoids some potential stack overflows with very deep softirq callchains. i386 does this too. TOADD CFI annotation Signed-off-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
