* Disable ext2/ext3 (as ext4 can be used to mount them).
* Enable AUFS/Squshfs support
* Misc improvements (e.g. ARM optimized AES code, disable
drivers/frameworks unlikely to be used)
Jan prefers to store the fully extended .config file so we will
do it. One advantage is to more easily see what has changed between
two kernel versions.

We want to enable the watchdog in the bootloader already and
for this to be failsafe we need to have a kernel that can boot
and get ethernet without any additional modules. Now systemd
would not be able to trigger the watchdog and the system would
reboot within 60 seconds. I am not sure how the kernel upgrade
will go and we need to try this.

We will change the MTD partitioning for our devices soon. The
kernel needs to honor the cmdline given by the kernel for that.
The rootfs will move a few pages to the back with newer bootloaders.
The name/structure of the NAT configuration was changed. Catch up
and put the new names into the old defconfig too. It is an ugly hack
to have it work with v3.2 and v3.10 kernels. The sysmobsc has been
fixed independently.
* The Linux 3.2.X kernel has some funny issues with GCC 4.8 in the
fs/namei.c look up code. It is easier to move to 3.10 than to fully
debug the issue.
* disable the mISDN loop patch for v3.10
* use the hack to make v3.2 compilable for edison and v3.10 for dora
this might help us in some installations where there are multiple
back-hauls and we want to base routing decisions not only based
on the destination IP.
There is no need to have the various pty files clobber the /dev
directory when they are never used. Do not force a PR upgrade
right now as we don't have a good upgreade strategy for the v1
and the BSC config.
The kernel has been rebased to target 3.2.40 with various bug
fixes in the upstream work. The sysmobts v2 config has been
changed to allocate space for two more UARTs. These are required
for the multi-trx configuration and they make a warning go away.
