If a regulator hasn't been enable by a driver but is enabled in hardware
(most likely enabled by U-Boot), regulator_status will returns that it
is enabled and so any call to regulator_disable will panic as it wasn't
enabled by one of our drivers.

For the discovery phase of SD/eMMC we need to do some transaction in a async
way.
The classic CAM XPT_{GET,SET}_TRAN_SETTING cannot be used in a async way.
This also allow us to split the discovery phase into a more complete state
machine and we don't mtx_sleep with a random number to wait for completion
of the tasks.
For mmc_sim we now do the SET_TRAN_SETTING in a taskqueue so we can call
the needed function for regulators/clocks without the cam lock(s). This part is
still needed to be done for sdhci.
We also now save the host OCR in the discovery phase as it wasn't done before and
only worked because the same ccb was reused.

task_struct allocations to be returned before freeing the UMA zone in the

Commit b3d4c70dc6 added support for CLAIM_DELEG_CUR_FH to Open.
While doing this, I noticed that CLAIM_DELEG_PREV_FH support
could be added the same way. Although I am not aware of any extant
NFSv4.1/4.2 client that uses this claim type, it seems prudent to add
support for this variant of Open to the NFSv4.1/4.2 server.
This patch does not affect mounts from extant NFSv4.1/4.2 clients,
as far as I know.

cxgbei stores state about a target transfer in the ctl_private[] array
of a ctl_io that is freed when a target transfer (represented by the
cdw) is freed. As such, freeing a ctl_io before a cdw that references
it can result in a use after free in cxgbei. Two of the four places
freed the cdw first, and the other two freed the ctl_io first. Fix
the latter two places to free the cdw first.

At this point the directory's vnode lock is held, so blocking while
waiting for free pages makes the system more susceptible to deadlock in
low memory conditions. This is particularly problematic on NUMA systems
as UMA currently implements a strict first-touch policy.
ufsdirhash_build() already uses M_NOWAIT for other allocations and
already handled failures for the block array allocation, so just convert
to M_NOWAIT.

Floating states get assigned to interface 'all' (V_pfi_all), so when we
try to flush all states for an interface states originally created
through this interface are not flushed. Only if-bound states can be
flushed in this way.
Given that we track the original interface we can check if the state's
interface is 'all', and if so compare to the orig_if instead.

* card does not support write-one-to-clear semantics for interrupt status

* MDIO operations can take longer to complete

The most difficult NFSv4 client recovery case happens when the
lease has expired on the server. For NFSv4.0, the client will
receive a NFSERR_EXPIRED reply from the server to indicate this
has happened.
For NFSv4.1/4.2, most RPCs have a Sequence operation and, as such,
the client will receive a NFSERR_BADSESSION reply when the lease
has expired for these RPCs. The client will then call nfscl_recover()
to handle the NFSERR_BADSESSION reply. However, for the expired lease
case, the first reclaim Open will fail with NFSERR_NOGRACE.
This patch recognizes this case and calls nfscl_expireclient()
to handle the recovery from an expired lease.
This patch only affects NFSv4.1/4.2 mounts when the lease
expires on the server, due to a network partitioning that
exceeds the lease duration or similar.
