2019-03-07	nios2: update_mmu_cache preload the TLB with the new PTE	Nicholas Piggin	1	-0/+6
	Rather than flush the TLB entry when installing a new PTE to allow the fast TLB reload to re-fill the TLB, just refill the TLB entry when removing the old one. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>
2019-03-07	nios2: flush_tlb_page use PID based flush	Nicholas Piggin	1	-4/+9
	flush_tlb_page is for flushing user pages, so it should not be using flush_tlb_one (which flushes all pages). This patch implements it with the flush_tlb_range, which is a user flush that does the right thing. flush_tlb_one is made static to mm/tlb.c because it's a bit confusing. It is used in do_page_fault to flush the kernel non-linear mappings, so that is replaced with flush_tlb_kernel_page. The end result is that functionality is identical.
