Subject: [PATCH] ARM: drop unused DEBUG_RODATA from XIP_KERNEL
Date: Tue, 16 Feb 2016 12:29:57 -0800 [thread overview]
Message-ID: <20160216202957.GA1826@www.outflux.net> (raw)
With CONFIG_DEBUG_RODATA not being sensible under XIP_KERNEL, remove it
from the XIP linker script.
Signed-off-by: Kees Cook <keescook@chromium.org>

Effectively the patch after Arnd's "ARM: mm: hide
__start_rodata_section_aligned for non-debug builds"
