FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64, mips32r2 and mips64r2 (and close relatives) processors. There presently is support for ADMtek ADM5120, A mips 4Kc in a malta board, the RB533 routerboard (based on IDT RC32434) and some preliminary support for sibtye/broadcom designs. Other hardware support will be forthcomcing. This port boots multiuser under gxemul emulating the malta board and also bootstraps on the hardware whose support is forthcoming...

Stash the context of the running thread at the time an IPI_STOP is received in 'stoppcbs[]'. We use the 'stoppcbs[]' context to generate the backtrace of such stopped threads.

#ifdef INTRNG
Begin the MIPS_INTRNG support. This is a prelude to intr-ng support for MIPS boards that need it - notably the CI20 port from kan@ that's upcoming, but also work that Stanislav is doing for the Mediatek platforms. This is the initial platform dependent bits in include/intr.h, some #defines for the nexus code for the intrng initialisation/runtime bits, some changed naming (which I'll fix later to be the same, much like what I did for ARM intr-ng) in exception.S, and the first cut at a PIC. Stanislav and I refactored out the common code for intrng support, so the mips intrng definitions are quite small (sys/mips/include/intr.h.) This is all work done by kan@, which stanislav has been cherry picking into common code for his mediatek chipset work. Tested: * Carambola2 - no regressions (not intr-ng though!)

* Completely Remove the option STOP_NMI from the kernel. This option has proven to have a good effect when entering KDB by using a NMI, but it completely violates all the good rules about interrupts disabled while holding a spinlock in other occasions. This can be the cause of deadlocks on events where a normal IPI_STOP is expected. * Adds an new IPI called IPI_STOP_HARD on all the supported architectures. This IPI is responsible for sending a stop message among CPUs using a privileged channel when disponible. In other cases it just does match a normal IPI_STOP. Right now the IPI_STOP_HARD functionality uses a NMI on ia32 and amd64 architectures, while on the other has a normal IPI_STOP effect. It is responsibility of maintainers to eventually implement an hard stop when necessary and possible. * Use the new IPI facility in order to implement a new userend SMP kernel function called stop_cpus_hard(). That is specular to stop_cpu() but it does use the privileged channel for the stopping facility. * Let KDB use the newly introduced function stop_cpus_hard() and leave stop_cpus() for all the other cases * Disable interrupts on CPU0 when starting the process of APs suspension. * Style cleanup and comments adding This patch should fix the reboot/shutdown deadlocks many users are constantly reporting on mailing lists. Please don't forget to update your config file with the STOP_NMI option removal Reviewed by: jhb Tested by: pho, bz, rink Approved by: re (kib)

void ipi_all_but_self(int ipi);
Add a new ipi_cpu() function to the MI IPI API that can be used to send an IPI to a specific CPU by its cpuid. Replace calls to ipi_selected() that constructed a mask for a single CPU with calls to ipi_cpu() instead. This will matter more in the future when we transition from cpumask_t to cpuset_t for CPU masks in which case building a CPU mask is more expensive.
