In some cases it seems that the PHY mode can only be identified by
matching against the corresponding device node name in the FDT. r334880
broke this for the case where the node name contains a unit address.
Fix the problem by allowing a match in that case.

- Resources used by spigen_mmap_single() are now tracked using
devfs_set_cdevpriv() rather than in the softc.
- Since resources are now tracked per-open-fd, there is no need to try to
impose any exclusive-open logic, so flags related to that are removed.
- Flags used to track open status to prevent detach() when the device is
open are replaced with calls to device_busy()/device_unbusy(). That
extends the protection up the hierarchy so that the spibus and hardware
controller drivers also can't be detached while the device is open/in use.
- Arbitrary limits on the maximum size of a transfer are removed, along with
the sysctl variables that allowed the limits to be changed. There is just
no reason to limit the size of a spi transfer to the machine's page size.
Or to any other arbitrary value, really.
- Most of the locking is removed. It was mostly protecting access to flags
and fields in the softc that no longer exist. The locking that remains is
just to prevent concurrent calls to device_[un]busy().
- The code was calling malloc() with M_WAITOK while holding a mutex in
several places. Since most of the locking is gone, that's fixed.
Summary:
Add the device id of the Panda Wireless PAU06 which seems to be
the already-supported combination of RT5392 MAC and RF RT5372
radio.

Make unsigned values uint16_t for pnp table. They are properly
uint16_t befause they are 16-bit PCI IDs. The PNP_INFO language has no
type for bare unsigned.

FreeBSD VM can't boot up on Hyper-V after the recent malloc change in
r335068: Make UMA and malloc(9) return non-executable memory in most cases.
The hypercall page here must be executable.
Fix the boot-up issue by adding M_EXEC.

doing it last. Also, remove the local tracking of whether usb's busdma
memory allocation got done, because it's safe to call the free_all
function even if it wasn't.
r333175 (multicast changes) exposed a bug where
mxge was not checking to see if the driver was being
unloaded while handing ioctls that touch hardware.
As a result, now that in6m_disconnect() is run from
an async gtaskq, it was busy-waiting in mxge_send_cmd()
while the mcast list was destroyed.
Also replace numbered list with - bulleted so the list entries do not
need to be renumbered as tasks are completed.

It's likely that the header was needed in the past for swi(9).
But now that code does not use swi(9) or any other interfaces defined

- Add tracker argument to preemptible epochs
- Inline epoch read path in kernel and tied modules
- Change in_epoch to take an epoch as argument
- Simplify tfb_tcp_do_segment to not take a ti_locked argument,
there's no longer any benefit to dropping the pcbinfo lock
and trying to do so just adds an error prone branchfest to
these functions
- Remove cases of same function recursion on the epoch as
recursing is no longer free.
- Remove the the TAILQ_ENTRY and epoch_section from struct
thread as the tracker field is now stack or heap allocated
as appropriate.
