Subject: arch/arm/configs/tizen_defconfig: Select no forced preemption
X-Git-Tag: 2.2.1_release^2~83^2~7^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=24c91ddc7e00ccceea7dfec5739af88866155e11;p=sdk%2Femulator%2Femulator-kernel.git

arch/arm/configs/tizen_defconfig: Select no forced preemption

It seems that "Server" behaviour is more suitable for emulation
then "Desktop". It's because more frequent traslation block
interrupts can occure if kernel is preemtable.
