You're s-o-b is missing, along with the changed you did to the patch.

The newly added SIDLE_SMART_WKUP flag is missing.

The alphabetical order is not respected. Smartreflex should be before wd_timer.
Since Tony already pull that from Kevin's tree, I'll send a patch to Tony to fix these issues.
Please note the following log when enabling SR in Class 3 on an OMAP4430/sdp:
[ 2.362182] omap2_set_init_voltage: unable to find boot up OPP for vdd_mpu
[ 2.369384] omap2_set_init_voltage: Unable to put vdd_mpu to its init voltage

Is it expected?
Why do we have that blank line in-between?
