With the new interrupt rework, an interrupt "host" map() callback can be
called after the interrupt is already active.

It's called again for an already mapped interrupt to allow changing the
trigger setup, and currently this is not guarded with a test of wether
the interrupt is requested or not.

I plan to change some of this logic to be a bit less lenient against
random reconfiguring of live interrupts but just not yet.

The ported MPIC driver has a bug where when that happens, it will mask
the interrupt. This changes it to preserve the previous masking of the
interrupt instead.

Reimplement controller-wide PM. ata_host_set_suspend/resume() are
defined to suspend and resume a host_set. While suspended, EHs for
all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and
frozen.

Because SCSI device hotplug is done asynchronously against the rest of
libata EH and the same mutex is used when adding new device, suspend
cannot wait for hotplug to complete. So, if SCSI device hotplug is in
progress, suspend fails with -EBUSY.

In most cases, host_set resume is followed by device resume. As each
resume operation requires a reset, a single host_set-wide resume
operation may result in multiple resets. To avoid this, resume waits
upto 1 second giving PM to request resume for devices.

There is a code sequence where the locking is substream->self_group.lock
-> ins->scbs[index].lock

substream->self_group.lock is interrupt safe, and taken from irq context
as well (trace is snipped for brevity)

so what can happen is

cpu 0 cpu 1
user context user context

take ins->scbs[index].lock without disabling interrupts

get substream->self_group.lock (irqsafe)
try to get ins->scbs[index].lock (spins)

interrupt happens
try to get substream->self_group.lock (spins)

which is an obvious AB-BA deadlock

fix is to just take the lock with _irqsafe

Reimplement per-dev PM. The original implementation directly put the
device into suspended mode and didn't synchronize w/ EH operations
including hotplug. This patch reimplements ata_scsi_device_suspend()
and ata_scsi_device_resume() such that they request EH to perform the
respective operations. Both functions synchronize with hotplug such
that it doesn't operate on detached devices.

Suspend waits for completion but resume just issues request and
returns. This allows parallel wake up of devices and thus speeds up
system resume.

Due to sdev detach synchronization, it's not feasible to separate out
EH requesting from sdev handling; thus, ata_device_suspend/resume()
are removed and everything is implemented in the respective
libata-scsi functions.

mthca: initialize send and receive queue locks separately

lockdep identifies a lock by the call site of its initialization. By
initializing the send and receive queue locks in mthca_wq_init() we confuse
lockdep. It warns that that the ordered acquiry of both locks in
mthca_modify_qp() is recursive acquiry of one lock:

=============================================
[ INFO: possible recursive locking detected ]
---------------------------------------------
modprobe/1192 is trying to acquire lock:
(&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca]
but task is already holding lock:
(&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca]

Initializing the locks separately in mthca_alloc_qp_common() stops the
warning and will let lockdep enforce proper ordering on paths that acquire
both locks.
