While coalescing all ECN-related code into new common source files,
the flag to deal with SACK retransmissions was skipped. This leads
to non-compliant ECT-marking of SACK retransmissions, as well as
the premature sending of other TCP ECN flags (CWR).

Use get_pcpu() instead of an open-coded pcpu_find(td->td_oncpu). This
eliminates some memory accesses and results in a shorter instruction

ler@, markj@ reported a use after free in nfscl_cleanupkext().
They also provided two possible causes:
- In nfscl_cleanup_common(), "own" is the owner string
owp->nfsow_owner. If we free that particular
owner structure, than in subsequent comparisons
"own" will point to freed memory.
- nfscl_cleanup_common() can free more than one owner, so the use
of LIST_FOREACH_SAFE() in nfscl_cleanupkext() is not sufficient.
I also believe there is a 3rd:
- If nfscl_freeopenowner() or nfscl_freelockowner() is called
without the NFSCLSTATE mutex held, this could race with
nfscl_cleanupkext().
This could happen when the exclusive lock is held
on the client, such as when delegations are being returned
or when recovering from NFSERR_EXPIRED.
This patch fixes them as follows:
1 - Copy the owner string to a local variable before the
nfscl_cleanup_common() call.
2 - Modify nfscl_cleanup_common() so that it will never free more
than the first matching element. Normally there should only
be one element in each list with a matching open/lock owner
anyhow (but there might be a bug that results in a duplicate).
This should guarantee that the FOREACH_SAFE loops in
nfscl_cleanupkext() are adequate.
3 - Acquire the NFSCLSTATE mutex in nfscl_freeopenowner()
and nfscl_freelockowner(), if it is not already held.
This serializes all of these calls with the ones done in
nfscl_cleanup_common().

Also add files not previously imported because we are not yet compiling
them to ease updating and having them when needed.
This adds MEI (Management Engine) support upstream which we cannot import
(currently GPL-only) so we have stub functions for the missing bits.
This also reduces the diff to upstream. Changes submitted to avoid
problems with const and with void * arithmetics were merged.

- UQ_MSC_NO_SYNC_CACHE
- UQ_MSC_NO_TEST_UNIT_READY
- UQ_MSC_NO_GETMAXLUN
- UQ_MSC_NO_START_STOP
If any of the quirks above are set, no further quirks will be probed.
If any of the USB mass storage tests fail, the USB device is
re-enumerated as a last resort to clear any error states from the
device. Then the USB stack will try to probe and attach the umass<N>

access per-mount and per-vnode data. Instead, follow the approach taken
by nullfs and use the vnode interlock coupled with the hold count to
ensure the mount and the vnode won't be recycled while they are being
accessed.
