I've got some feedback here.

Hi Grygorii,

We are running the entire patchset on top of
a7a6541db840cc4514a26fc12cc1bc94d1b9e873 from the git://
git.ti.com/ti-linux-kernel/ti-linux-kernel.git tree. I've pushed the
system pretty hard overnight and haven't seen any instability (with lockdep
enabled. We used to get splats pretty fast).

I wasn't on lkml when you sent the patchset out, so I'm not sure how to
best reply to the original thread with this info.
