- Export ExiTryToAcquireFastMutex from ntoskrnl, I had forgotten to export this ages ago when adding the other Exi*FastMutex* stuff.
- Remove fmutex.c and fastmutex functions from HAL. The whole point of having the Exi ones in the kernel was that HAL calls them through forward exports now (so any old driver can still link with HAL). Now we don't duplicate the implementation anymore. - Remove DriverEntry, it's useless. Also move HalReportResourceUsage to halinit because it's a call-once-on-boot function much akin a HalInitPhase2 function, so delete resource.c - Keep track of interrupt affinity and active processor mask each time a new CPU initializes. svn path=/trunk/; revision=24762
