Add upa.h, which I had previously forgotten, to unbreak the sparc64 kernel build. Pointy hat to: tmm 2002-01-08 16:25:51 +00:00			`/*-`

Add macros to extract the UPA module id from the UPA config register. This is the hardware cpuid. 2002-02-23 19:54:34 +00:00			`#define UPA_CR_MID_SHIFT (17)`

Add support for starting secondary cpus in kernel, as opposed to relying on the loader to do it. Improve smp startup code to be less racy and to defer certain things until the right time. This almost boots single user on my dual ultra 60, it is still very fragile: SMP: AP CPU #1 Launched!
