From 35f2fd04ce8bd3eaad4b7790abb19fa2a56d7314 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Thu, 19 Jan 2017 10:15:33 -0500 Subject: [PATCH] linux-user: fix tcg/mmap test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit tests/tcg/mmap test fails with values other than default target page size. When creating a map beyond EOF, extra anonymous pages are added up to the target page boundary. Currently, this operation is performed only when qemu_real_host_page_size < TARGET_PAGE_SIZE, but it should be performed if the configured page size (qemu -p) is larger than qemu_real_host_page_size too.
