From adeff42236aec0601ec979d1a41cd6d9cf5a8c05 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 10 Apr 2006 21:32:35 +0100 Subject: [ARM] 3470/1: Clear the HWCAP bits for the disabled kernel features Patch from Catalin Marinas Glibc interprets the HWCAP bits and decides on what features to use. However, even if the features are present in the hardware, they are not always supported by the kernel and hence the corresponding bits have to be cleared from the elf_hwcap variable.
