Gentle ping.
Any comments on the following patches:

genirq: Provide new interfaces for affinity hints
scsi: megaraid_sas: Use irq_set_affinity_and_hint
scsi: mpt3sas: Use irq_set_affinity_and_hint
enic: Use irq_update_affinity_hint
be2net: Use irq_update_affinity_hint
mailbox: Use irq_update_affinity_hint
hinic: Use irq_set_affinity_and_hint

or any other patches?
