From c158c3bf59951bbb44bd7ccca9e6665dfd1617c5 Mon Sep 17 00:00:00 2001 From: Roy Franz Date: Fri, 4 Oct 2013 09:02:46 -0700 Subject: [PATCH] boot, efi: Remove redundant memset() Remove a redundant memset() call from efi_relocate_kernel() that was clearing memory that would be used by BSS in non-compressed images loaded with this function. This clear was redundant with the clearing done in the image itself, and also implemented incorrectly with a 0 length.
