ARM: mxs: Remove MMAP_MIN_ADDR setting from mxs_defconfig
commit 3bed491c8d28329e34f8a31e3fe64d03f3a350f1 upstream. 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).
