[Linux-stable-mirror] Patch "fm10k: request reset when mbx->state changes" has been added to the 4.4-stable tree

This can leave certain mailbox messages from the PF to be untreated and the PF will enter in some inactive state. If this situation occurs, the IES API will initiate a mailbox version reset which, then, trigger a mailbox state change. Once this mailbox transition occurs (from OPEN to CONNECT state), a request for reset will be returned. This ensures that PF will undergo a reset whenever IES API encounters an unknown global mailbox interrupt event or whenever the IES API terminates.

Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()") introduced a bug (that is in fact documented by the patch commit text) that leaves behind a dangling pointer. Since the done_wait structure is allocated on the stack, future invocations to the DMATEST can produce undesirable results (e.g., corrupted spinlocks). Ideally, this would be cleaned up in the thread handler, but at the very least, the kernel is left in a very precarious scenario that can lead to some long debug sessions when the crash comes later.
