This diff changes IP30.MP kernels to no longer use LLAddr to store curcpu, but use unused fields of the MPConf structure in low memory, indexed with the physical processor id, which can be obtained from the Heart PRID register. move machine dependent GET_CPU_INFO(), getcurcpu(), setcurcpu() to arch/sgi. ok miod@ 2010-09-11T11:29:49Z syuu syuu@openbsd.org 2010-09-11T11:29:49Z urn:sha1:1d6e357129ea3f28b68046f1362026500e44724b Storeing current cpu_info address into LLAddr register, for curcpu(). 2010-04-28T16:20:28Z syuu syuu@openbsd.org 2010-04-28T16:20:28Z urn:sha1:afdabf13cf434cbb2164e59d58340fb877b5becf Instead of previous implementation, we won't use physical cpuid to fetch curcpu().

Implemented getcurcpu() and setcurcpu() for it, smp_malloc() renamed alloc_contiguous_pages() because now it only allocate by page. ok miod@ curproc, curprocpaddr moved into cpu_info 2009-09-30T06:22:00Z syuu syuu@openbsd.org 2009-09-30T06:22:00Z urn:sha1:1b9cca207f5b52d884331b5976e4c5a567a2c99e OK miod@ initial sgi import 2004-08-06T21:12:18Z pefo pefo@openbsd.org 2004-08-06T21:12:18Z urn:sha1:20fc814e6ef83a91b61bae20069de95193d31dff
