From 88b7ad10dd7cecfb5977f99175fe62ac2c511290 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 7 Aug 2023 11:42:11 +0200 Subject: [PATCH] target/hppa: Do not use hardcoded value for tlb_flush_*() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Avoid using hardcoded values when calling the tlb_flush*() functions. Instead, define and use HPPA_MMU_FLUSH_MASK (keeping the current behavior, which doesn't flush the physical address MMU).
