ARM: mxs: Remove MMAP_MIN_ADDR setting from mxs_defconfig
The CONFIG_DEFAULT_MMAP_MIN_ADDR was set to 65536 in mxs_defconfig,
this caused severe breakage of userland applications since the upper
limit for ARM is 32768. By default CONFIG_DEFAULT_MMAP_MIN_ADDR is
set to 4096 and can also be changed via /proc/sys/vm/mmap_min_addr
if needed.
Quoting Russell King [1]:
"4096 is also fine for ARM too. There's not much point in having
defconfigs change it - that would just be pure noise in the config
files."
the CONFIG_DEFAULT_MMAP_MIN_ADDR can be removed from the defconfig
altogether.
This problem was introduced by commit cde7c41 (ARM: configs: add
defconfig for mach-mxs).
