From 25804e6a96681d5d2142058948e218999e4f547c Mon Sep 17 00:00:00 2001 From: Steve Capper <Steve.Capper@arm.com> Date: Wed, 18 Sep 2013 16:14:28 +0100 Subject: [PATCH] arm64: Widen hwcap to be 64 bit Under arm64 elf_hwcap is a 32 bit quantity, but it is stored in a 64 bit auxiliary ELF field and glibc reads hwcap as 64 bit. This patch widens elf_hwcap to be 64 bit.
