Impact: cleanup Make the following uv related cleanups. * collect visible uv related definitions and interfaces into uv/uv.h and use it. this cleans up the messy situation where on 64bit, uv is defined properly, on 32bit generic it's dummy and on the rest undefined. after this clean up, uv is defined on 64 and dummy on 32. * update uv_flush_tlb_others() such that it takes cpumask of to-be-flushed cpus as argument, instead of that minus self, and returns yet-to-be-flushed cpumask, instead of modifying the passed in parameter. this interface change will ease dummy implementation of uv_flush_tlb_others() and makes uv tlb flush related stuff defined in tlb_uv proper.
