-Find attached the i386 cpu hotplug patch updated for Ingo's latest round of
-goodies. In order to avoid dumping cpu hotplug code into kernel/irq/* i
-dropped the cpu_online check in do_IRQ() by modifying fixup_irqs(). The
-difference being that on cpu offline, fixup_irqs() is called before we
-clear the cpu from cpu_online_map and a long delay in order to ensure that
-we never have any queued external interrupts on the APICs. Due to my usual
-test victims being in boxes a continent away this hasn't been tested, but
-i'll cover bug reports (nudge, Nathan! ;)
-
-1) Add CONFIG_HOTPLUG_CPU
-2) disable local APIC timer on dead cpus.
-3) Disable preempt around irq balancing to prevent CPUs going down.
-4) Print irq stats for all possible cpus.
-5) Debugging check for interrupts on offline cpus.
-6) Hacky fixup_irqs() to redirect irqs when cpus go off/online.
-7) play_dead() for offline cpus to spin inside.
-8) Handle offline cpus set in flush_tlb_others().
-9) Grab lock earlier in smp_call_function() to prevent CPUs going down.
-10) Implement __cpu_disable() and __cpu_die().
-11) Enable local interrupts in cpu_enable() after fixup_irqs()
-12) Don't fiddle with NMI on dead cpu, but leave intact on other cpus.
-13) Program IRQ affinity whilst cpu is still in cpu_online_map on offline.

-+Linux kernel developers take security very seriously. As such, we'd
-+like to know when a security bug is found so that it can be fixed and
-+disclosed as quickly as possible. Please report security bugs to the
-+Linux kernel security team.
-+
-+1) Contact
-+
-+The Linux kernel security team can be contacted by email at
-+<security@xxxxxxxxxx>. This is a private list of security officers
-+who will help verify the bug report and develop and release a fix.
-+It is possible that the security team will bring in extra help from
-+area maintainers to understand and fix the security vulnerability.
-+
-+As it is with any bug, the more information provided the easier it
-+will be to diagnose and fix. Please review the procedure outlined in
-+REPORTING-BUGS if you are unclear about what information is helpful.
-+Any exploit code is very helpful and will not be released without
-+consent from the reporter unless it has already been made public.
-+
-+2) Disclosure
-+
-+The goal of the Linux kernel security team is to work with the
-+bug submitter to bug resolution as well as disclosure. We prefer
-+to fully disclose the bug as soon as possible. It is reasonable to
-+delay disclosure when the bug or the fix is not yet fully understood,
-+the solution is not well-tested or for vendor coordination. However, we
-+expect these delays to be short, measurable in days, not weeks or months.
-+A disclosure date is negotiated by the security team working with the
-+bug submitter as well as vendors. However, the kernel security team
-+holds the final say when setting a disclosure date. The timeframe for
-+disclosure is from immediate (esp. if it's already publically known)
-+to a few weeks. As a basic default policy, we expect report date to
-+disclosure date to be on the order of 7 days.
-+
-+3) Non-disclosure agreements
-+
-+The Linux kernel security team is not a formal body and therefore unable
-+to enter any non-disclosure agreements.
