the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the order to set up a fake set of threads to point each cpu at really early in boot to make sure that at all points in code it can get the current 'thread' and thus the current cpu. A probably better solution would be to have dr3 point to the current cpu which would then point to the current thread, but that has a race condition that would require an int disable, etc. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20160 a95241bf-73f2-0310-859d-f6bbb57e9c96
