2019-10-29	RISC-V: Issue a tlb page flush if possible	Atish Patra	1	-1/+4
	If tlbflush request is for page only, there is no need to do a complete local tlb shootdown. Just do a local tlb flush for the given address. Signed-off-by: Atish Patra <atish.patra@wdc.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
2019-10-29	RISC-V: Issue a local tlbflush if possible.	Atish Patra	1	-2/+17
	In RISC-V, tlb flush happens via SBI which is expensive. If the local cpu is the only cpu in cpumask, there is no need to invoke a SBI call. Just do a local flush and return.

	SBI calls are expensive. If cpumask is empty, there is no need to trap via SBI as no remote tlb flushing is required. Signed-off-by: Atish Patra <atish.patra@wdc.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
