The RISC-V kernel implementation of flush_tlb_page() when CONFIG_SMP is set is wrong. It passes zero to flush_tlb_range() as the final address to flush, but it should be at least 'addr'. Some other Linux architecture ports use the beginning address to flush, plus PAGE_SIZE, as the final address to flush. This might flush slightly more than what's needed, but it seems unlikely that being more clever would improve anything. So let's just take that implementation for now. While here, convert the macro into a static inline function, primarily to avoid unintentional multiple evaluations of 'addr'. This second version of the patch fixes a coding style issue found by Christoph Hellwig <hch@lst.de>.
