| Subject: ARM: mxs: Remove MMAP_MIN_ADDR setting from mxs_defconfig |
| |
| From: Marek Vasut <marex@denx.de> |
| |
| 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). |
