From 2493d3e28a22087116158249d79410fd355d1e83 Mon Sep 17 00:00:00 2001 From: Rabin Vincent Date: Fri, 27 Mar 2015 22:35:11 +0100 Subject: CRIS: UAPI: fix elf.h export CRIS userspace (uClibc for one) expects asm/elf.h to be exported but this header appears to have gone missing at some point. Move it to uapi/ and export it.
