2010-05-24powerpc/kexec: Add support for FSL-BookESebastian Andrzej Siewior
This adds support kexec on FSL-BookE where the MMU can not be simply switched off. The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available.

2010-05-24x86: "nosmp" command line option should force the system into UP modeJan Beulich
Bits set in cpu_possible_mask prior to the execution of prefill_possible_map() (i.e. when parsing ACPI or MPS tables) would prevent the SMP alternatives logic from switching to UP mode, plus unnecessary setup of per-CPU data for CPUs that can never come online. Additionally, without CONFIG_HOTPLUG_CPU disabled CPUs can never come online, and hence setting cpu_possible_mask bits for them is again a simple waste of resources.

2010-05-24x86, apic: ack all pending irqs when crashed/on kexecKerstin Jonsson
When the SMP kernel decides to crash_kexec() the local APICs may have pending interrupts in their vector tables. The setup routine for the local APIC has a deficient mechanism for clearing these interrupts, it only handles interrupts that has already been dispatched to the local core for servicing (the ISR register) safely, it doesn't consider lower prioritized queued interrupts stored in the IRR register. If you have more than one pending interrupt within the same 32 bit word in the LAPIC vector table registers you may find yourself entering the IO APIC setup with pending interrupts left in the LAPIC. This is a situation for wich the IO APIC setup is not prepared. Depending of what/which interrupt vector/vectors are stuck in the APIC tables your system may show various degrees of malfunctioning. That was the reason why the check_timer() failed in our system, the timer interrupts was blocked by pending interrupts from the old kernel when routed trough the IO APIC. Additional comment from Jiri Bohac: ============== If this should go into stable release, I'd add some kind of limit on the number of iterations, just to be safe from hard to debug lock-ups: +if (loops++ > MAX_LOOPS) { + printk("LAPIC pending clean-up") + break; +} while (queued); with MAX_LOOPS something like 1E9 this would leave plenty of time for the pending IRQs to be cleared and would and still cause at most a second of delay if the loop were to lock-up for whatever reason. [trenn@suse.de: V2: Use tsc if avail to bail out after 1 sec due to possible virtual apic_read calls which may take rather long (suggested by: Avi Kivity <avi@redhat.com>) If no tsc is available bail out quickly after cpu_khz, if we broke out too early and still have irqs pending (which should never happen?) we still get a WARN_ON... V3: - Fixed indentation -> checkpatch clean - max_loops must be signed V4: - Fix typo, mixed up tsc and ntsc in first rdtscll() call V5: Adjust WARN_ON() condition to also catch error in cpu_has_tsc case] Cc: <jbohac@novell.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Kerstin Jonsson <kerstin.jonsson@ericsson.com> Cc: Avi Kivity <avi@redhat.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Tested-by: Eric W.
