- Add invfo_rdwr() (for read and write), invfo_ioctl(), invfo_poll(),
and invfo_kqfilter() for use by file types that do not support the
respective operations. Home-grown versions of invfo_poll() were
universally broken (they returned an errno value, invfo_poll()
uses poll_no_poll() to return an appropriate event mask). Home-grown
ioctl routines also tended to return an incorrect errno (invfo_ioctl
returns ENOTTY).
- Use the invfo_*() functions instead of local versions for
unsupported file operations.
- Reorder fileops members to match the order in the structure definition
to make it easier to spot missing members.
- Add several missing methods to linuxfileops used by the OFED shim
layer: fo_write(), fo_truncate(), fo_kqfilter(), and fo_stat(). Most
of these used invfo_*(), but a dummy fo_stat() implementation was
added.
instead of breaking out of the loop and then immediately checking the loop

before creating a mapping for the resource.

by explicitly moving it out of the interrupt shadow. The hypervisor is done
"executing" the HLT and by definition this moves the vcpu out of the
1-instruction interrupt shadow.
Prior to this change the interrupt would be held pending because the VMCS
guest-interruptibility-state would indicate that "blocking by STI" was in
effect. This resulted in an unnecessary round trip into the guest before
the pending interrupt could be injected.

the second sector by only clearing the amount of bytes needed for the
disklabel in the second sector. Previously we were clearing exactly 1
sector worth of bytes and as such writing over boot code that may have
been there.
Since we do support more than 8 partitions, make sure to set all fields
in d_partitions. For the first 8 partitions this is unneeded, but for
partitioons 9 and up this compensates for the fact that we don't clear
an entire sector anymore.
Obviously, one cannot use more than 8 partitions when using boot code
that starts right after the disk label.
Relevant GRNs:
107879 - Employ unused bytes after the disklabel in the second sector.
189500 - Revert the part of change 107879 that employs the unused bytes
after the disklabel in the 2nd sector for boot code.

2. Start the checksum from the beginning of the label; not the beginning

ifa_ifwithdstaddr. For the sake of backwards compatibility, the new
arguments were added to new functions named ifa_ifwithnet_fib and
ifa_ifwithdstaddr_fib, while the old functions became wrappers around the
new ones that passed RT_ALL_FIBS for the fib argument. However, the
backwards compatibility is not desired for FreeBSD 11, because there are
numerous other incompatible changes to the ifnet(9) API. We therefore
decided to remove it from head but leave it in place for stable/9 and
stable/10. In addition, this commit adds the fib argument to
ifa_ifwithbroadaddr for consistency's sake.

an mbuf's storage (internal or external).
Add a new M_SIZE() mbuf macro that returns the size of an mbuf's
storage (internal or external).
These contrast with m_data and m_len, which are with respect to data
in the buffer, rather than the buffer itself.
Rewrite M_LEADINGSPACE() and M_TRAILINGSPACE() in terms of M_START()
and M_SIZE().
This is done as we currently have many instances of using mbuf flags
to generate pointers or lengths for internal storage in header and
regular mbufs, as well as to external storage. Rather than replicate
this logic throughout the network stack, centralising the
implementation will make it easier for us to refine mbuf storage.
This should also help reduce bugs by limiting the amount of
mbuf-type-specific pointer arithmetic. Followup changes will
propagate use of the macros throughout the stack.
M_SIZE() conflicts with one macro in the Chelsio driver; rename that
macro in a slightly unsatisfying way to eliminate the collision.
