Hi Greg,
Apologies on the delay since last email; here are some patches from ubuntu xenial 4.4 for your consideration towards stable-4.4.y.
cc: stable ab2a4bf83902c170d29ba130a8abb5f9d90559e1 USB: don't free bandwidth_mutex too early c538b9436751a0be2e1246b48353bc23156bdbcc pinctrl: intel: Only restore pins that are used by the driver
Seem useful; similar patches already in stable 3a020a723c65eb8ffa7c237faca26521a024e582 crypto: ghash-clmulni - Fix load failure 1a07834024dfca5c4bed5de8f8714306e0a11836 crypto: cryptd - Assign statesize properly ddef482420b1ba8ec45e6123a7e8d3f67b21e5e3 crypto: mcryptd - Fix load failure

A few more 'maybe's' that aren't marked cc: stable, but seemed useful; I had lesser confidence in these, so listing them separate from the above 'seem useful' ones
e9c5e7402dad6f4f04c2430db6f283512bcd4392 drm/amdgpu: add missing irq.h include => seems useful for building amdgpu on ARM
727f28b8ca24a581c7bd868326b8cea1058c720a tpm_tis: Use devm_free_irq not free_irq => simple fix
757647e10e55c01fb7a9c4356529442e316a7c72 hv_netvsc: use skb_get_hash() instead of a homegrown implementation => fixes performance regression
4aec6ec0da9c72c0fa1a5b0d1133707481347bb3 cxl: Increase timeout for detection of AFU mmio hang => helps detect mmio hang
725fc629ff2545b061407305ae51016c9f928fce kernek/fork.c: allocate idle task for a CPU always on its local node => performance improvement?
cd95aad5579371ac332507fc946008217fc37e6c Drivers: hv: vmbus: handle various crash scenarios => avoid kernel crashes
Hope these make some sense; with these, I've scanned through about 2300 patches till Jan'17 (Ubuntu-4.4.0-62.83 tag). I will continue to do this for the changes since then.
Best regards, Sumit
