[PATCH] MIPS: Do not flush tlb when setting pmd entry

2020-06-03 Thread Bibo Mao
Function set_pmd_at is to set pmd entry, if tlb entry need to be flushed, there exists pmdp_huge_clear_flush alike function before set_pmd_at is called. So it is not necessary to call flush_tlb_all in this function. Signed-off-by: Bibo Mao --- arch/mips/mm/pgtable-64.c | 1 - 1 file changed, 1 d
