From d10eb08f5d8389c814b554d01aa2882ac58221bf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Mon, 14 Nov 2016 14:17:28 +0000 Subject: [PATCH] cputlb: drop flush_global flag from tlb_flush MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We have never has the concept of global TLB entries which would avoid the flush so we never actually use this flag. Drop it and make clear that tlb_flush is the sledge-hammer it has always been.
