We should turn on CONFIG_ARM_UNWIND in all the global configs if it's not already on. Thumb-2 requires it in practice, but it does no harm for ARM either -- in principle it may reduce run-time stack usage in the kernel by a small amount (but don't quote me on that) Cheers ---Dave _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
