Seems like all of these ought to be coming via stable. Have you 
mentioned any of these patches on the stable mailing list?

No, I haven't. Should I send them to stable instead of SRU?

Thanks,

It's a private bug in the beginning, and it's public now. Sorry for that.

Thanks,

Lets do both so that the rest of the community can benefit. You might 
want to refresh your memory of stable procedures by reviewing 
Documentation/stable_kernel_rules.txt in the kernel repo. Be sure to 
mention to which kernel version(s) that these patches apply.
