[PATCH] ARM: exynos_defconfig: Enable DYNAMIC_DEBUG and get rid of old ext3

Show all headers | View raw

DYNAMIC_DEBUG is quite useful for debugging kernels and should not cause
noticeable performance regressions.  It makes the kernel noticeably
bigger (around 4%) but this difference should not impact typical
developer and reference usage of this defconfig.

Sizes:
zImage-old:       4641496 bytes
zImage-new:       4811384 bytes

   text	   data	    bss	    dec	    hex	filename
7031229	2570916	 327016	9929161	 9781c9	vmlinux-old
7205921	2800052	 327016	10332989 9dab3d	vmlinux-new

Additionally, remove the EXT3_FS symbol because it is entirely replaced
by EXT4_FS.
