From 2d0fc797faaa73fbc1d30f5f9e90407bf3dd93f0 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Mon, 18 Jan 2021 14:38:04 +0800 Subject: [PATCH] elf2dmp: Rename PAGE_SIZE to ELF2DMP_PAGE_SIZE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As per POSIX specification of limits.h [1], OS libc may define PAGE_SIZE in limits.h. To prevent collosion of definition, we rename PAGE_SIZE here.
