Drop THUMB2 config workaround from the build script

[Milo Casagrande]

In the 'jenkins_common_lib' file we have a workaround to for a specific kernel. This should be avoided in the linaro-ci scripts, and handled directly in the kernel config fragments.

The lines are:

# Enabling the THUMB2 kernel option as the THUMB kernel does not seem to work
# well with THUMB2 userspace. This fixes the reboot issue(bug: 860556) we have seen
# for THUMB Kernel working with THUMB2 userspace.

echo "CONFIG_ARCH_OMAP2=n" >> $WORKSPACE/$pkg_dir/.config
echo "CONFIG_THUMB2_KERNEL=y" >> $WORKSPACE/$pkg_dir/.config

Andrey, could you ensure this is properly handled at linux-linaro config fragments level?
The proper fix should be there.

Fathi,

The linux-linaro-core-tracking and the linux-linaro trees use config fragments from config-*-tracking (equivalent to config-*-3.7 at the moment) branches of kernel/configs.git. There CONFIG_THUMB2_KERNEL=y is already in linaro-base.conf, and no other config fragment redefines this (Tixy has fixed android.conf WRT CONFIG_THUMB2_KERNEL on Nov 5, 2012). CONFIG_ARCH_OMAP2 is applicable to linaro/configs/omap4.conf only, and is disabled there. Adding "# CONFIG_ARCH_OMAP2 is not set" to linaro-base.conf wouldn't break anything, but is overkill, looks ugly, and adds more buzz to logs ("Value requested for CONFIG_ARCH_OMAP2 not in final .config ... Actual value:" for all non-OMAP configs).

The linux-linaro-tracking tree (the v3.4 based one) doesn't use config fragments at all.

So the current linux-linaro config fragments handle this OK already.
