From b36b2b1d3d41c02cc3a112df95478a4bd46d5f9a Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Tue, 2 Jan 2024 12:57:45 +1100 Subject: [PATCH] linux-user: Remove HOST_PAGE_ALIGN from mmap.c This removes a hidden use of qemu_host_page_size, using instead the existing host_page_size local within each function.
