08fe1020ba Make "-S" a default option for mountd.
After a discussion on freebsd-fs@ there seemed to be a consensus that
the "-S" option for mountd should become the default.
Since the only known issue w.r.t. using "-S" was fixed by r299201,
this commit adds "-S" to the default mountd_flags.

c04eb7cb4e [bhnd] Initial bhnd(4) SPROM/NVRAM support.
This adds support for the NVRAM handling and the basic SPROM
hardware used on siba(4) and bcma(4) devices, including:

* SPROM directly attached to the PCI core, accessible via PCI configuration
  space.
* SPROM attached to later ChipCommon cores.
* SPROM variables vended from the parent SoC bus (e.g. via a directly-attached
  flash device).

Additional improvements to the NVRAM/SPROM interface will
be required, but this changeset stands alone as working
checkpoint.

2f51e8d0c7 Don't increment srvrpccnt[] for the NFSv4.1 operations.
When support for NFSv4.1 was added to the NFS server, it broke
the server rpc count stats, since newnfsstats.srvrpccnt[] doesn't
have entries for the new NFSv4.1 operations.
Without this patch, the code was incrementing bogus entries in
newnfsstats for the new NFSv4.1 operations.
This patch is an interim fix. The nfsstats structure needs to be
updated and that will come in a future commit.

5a10a1e2e6 Use DDP to implement zerocopy TCP receive with aio_read().
Chelsio's TCP offload engine supports direct DMA of received TCP payload
into wired user buffers.  This feature is known as Direct-Data Placement.
However, to scale well the adapter needs to prepare buffers for DDP
before data arrives.  aio_read() is more amenable to this requirement than
read() as applications often call read() only after data is available in
the socket buffer.

When DDP is enabled, TOE sockets use the recently added pru_aio_queue
protocol hook to claim aio_read(2) requests instead of letting them use
the default AIO socket logic.  The DDP feature supports scheduling DMA
to two buffers at a time so that the second buffer is ready for use
after the first buffer is filled.  The aio/DDP code optimizes the case
of an application ping-ponging between two buffers (similar to the
zero-copy bpf(4) code) by keeping the two most recently used AIO buffers
wired.  If a buffer is reused, the aio/DDP code is able to reuse the
vm_page_t array as well as page pod mappings (a kind of MMU mapping the
Chelsio NIC uses to describe user buffers).  The generation of the
vmspace of the calling process is used in conjunction with the user
buffer's address and length to determine if a user buffer matches a
previously used buffer.  If an application queues a buffer for AIO that
does not match a previously used buffer then the least recently used
buffer is unwired before the new buffer is wired.  This ensures that no
more than two user buffers per socket are ever wired.

Note that this feature is best suited to applications sending a steady
stream of data vs short bursts of traffic.

2f6c86a8e7 Restore name=value format of PCI location strings.
When devctl was added, the location string for PCI devices was changed to
use the PCI "selector" that pciconf and devctl accept.  However, devd
assumes that location strings are formatted as a list of name=value pairs.
As a result, devd is no longer parsing any of the values out of PCI
device events.  Restore the previous format of the PCI location strings
to restore the location and slot keywords in case any devd scripts are
using this.  Add the "selector" as a new 'dbsf' location variable.

b53514c2e2 Give mountd -S priority over outstanding RPC requests when suspending the nfsd.
It was reported via email that under certain heavy RPC loads
long delays before the exports would be updated was observed
when using "mountd -S". This patch reverses the priority between
the exclusive lock request to suspend the nfsd threads and the
shared lock request for performing RPCs.
As such, when mountd attempts to suspend the nfsd threads, it
gets priority over outstanding RPC requests to do this.
I suspect that the case reported was an artificial test load,
but this patch did fix the problem for the reporter.

8e9c8dae36 xen/privcmd: fix integer truncation in IOCTL_PRIVCMD_MMAPBATCH
The size field in the XENMEM_add_to_physmap_range is an uint16_t, and the
privcmd driver was doing an implicit truncation of an int into an uint16_t
when filling the hypercall parameters.

Fix this by adding a loop and making sure privcmd splits ioctl request into
2^16 chunks when issuing the hypercalls.
