Subject: [ 38/44] ARM: mxs: Remove MMAP_MIN_ADDR setting from mxs_defconfig
Date: Mon, 13 Aug 2012 15:02:45 -0700 [thread overview]
Message-ID: <20120813220145.516295476@linuxfoundation.org> (raw)
In-Reply-To: <20120813220142.113186818@linuxfoundation.org>
From: Greg KH <gregkh@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
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).
