From 038adc2f5850e32019bda06c559d0301be436eae Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Sun, 13 Oct 2019 10:11:45 +0800 Subject: core: replace getpagesize() with qemu_real_host_page_size There are three page size in qemu: real host page size host page size target page size All of them have dedicate variable to represent. For the last two, we use the same form in the whole qemu project, while for the first one we use two forms: qemu_real_host_page_size and getpagesize(). qemu_real_host_page_size is defined to be a replacement of getpagesize(), so let it serve the role.
