Subject: [PATCH] ARM: fix perf build with uclibc toolchains
Message-ID: <201108091324.17750.florian@openwrt.org>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

libio.h is not provided by uClibc, in order to be able to test the
definition of __UCLIBC__ we need to include stdlib.h, which also
includes stddef.h, providing the definition of 'NULL'.
