instead of breaking out of the loop and then immediately checking the loop

Optimize the common case of injecting an interrupt into a vcpu after a HLT
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.
Be compatible with boot code that starts right after the disk label in
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.

Fix checksum calculation:
1. Iterate over all partitions counted in the label, which can be more

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

Attach the ISO to an ahci-cd emulated device. The

Revisions 264905 and 266860 added a "int fib" argument to ifa_ifwithnet and
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.

Add new a M_START() mbuf macro that returns a pointer to the start of
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.
Use the linker to perform relocations in the SUNW_dof section rather than
doing them in drti during startup. This fixes a number of problems with

USDT probes in static functions.
Fix a bug which could break extended attributes in a dump output.
This occurred when a file was >892kB long and had a large data (>1kB)

MFamd64: Use initializecpu() to set various model-specific registers on
AP startup and AP resume (it was already used for BSP startup and BSP
resume).
- Split code to do one-time probing of cache properties out of
initializecpu() and into initializecpucache(). This is called once on
the BSP during boot.
- Move enable_sse() into initializecpu().
- Call initializecpu() for AP startup instead of enable_sse() and
manually frobbing MSR_EFER to enable PG_NX.
- Call initializecpu() when an AP resumes. In theory this will now
properly re-enable PG_NX in MSR_EFER when resuming a PAE kernel on
APs.
To workaround an errata on certain Pentium Pro CPUs, i386 disables
the local APIC in initializecpu() and re-enables it if the APIC code
decides to use the local APIC after all. Rework this workaround
slightly so that initializecpu() won't re-disable the local APIC if
it is called after the APIC code re-enables the local APIC.
None of existing STEC devices need UNMAP or even support it well, having
many limitations and even hanging sometimes executing those commands.
New devices that may use UNMAP going to be released under HGST name.
Add support for calling pcibios routines from the
bootloader. Implement the following routines:
pcibios-device-count count the number of instances of a devid
pcibios-read-config read pci config space
pcibios-write-config write pci config space
pcibios-find-devclass find the nth device with a given devclass
pcibios-find-device find the nth device with a given devid
pcibios-locator convert bus device function ti pcibios locator
These commands are thin wrappers over their PCI BIOS 2.1 counterparts. More
informaiton, such as it is, can be found in the standard.
Export a nunmber of pcibios.X variables into the environment to report
what the PCI IDENTIFY command returned.
Also implmenet a new command line primitive (pci-device-count), but don't
include it by default just yet, since it depends on the recently added
words and any errors here can render a system unbootable.
This is intended to allow the boot loader to do special things based
on the hardware it finds. This could be have special settings that are
optimized for the specific cards, or even loading special drivers. It
goes without saying that writing to pci config space should not be
done without a just cause and a sound mind.
Conditionalize build of etcupdate(8) on MK_RCS. Since etcupdate calls
merge(1), which is part of the RCS package, it must not be installed if
WITHOUT_RCS update is set. Otherwise, it will produce confusing errors.
Add scope zone id to the in_endpoints and hc_metrics structures.
A non-global IPv6 address can be used in more than one zone of the same
scope. This zone index is used to identify to which zone a non-global
address belongs.
Also we can have many foreign hosts with equal non-global addresses,
but from different zones. So, they can have different metrics in the
host cache.
Add additional checks for IPV6_PKTINFO handling (RFC 3542):
* Return ENETDOWN when interface specified by ipi6_ifindex is not
enabled for IPv6 use.
* Return EADDRNOTAVAIL when ipi6_ifindex specifies an interface, but the
address ipi6_addr is not available for use on that interface.
* Return EINVAL when ipi6_addr is multicast address.
Make it possible to disable NOP-In PDUs by the iSCSI initiator by setting

Replace local copy-and-paste implementations of printmbuf() in several
device drivers with calls to the centralised m_print() implementation.
While the formatting and output details differ a little, the content
is essentially the same, and it is unlikely anyone has used this
debugging output in some time.
This change reduces awareness of mbuf cluster allocation (and,
especially, the M_EXT flag) outside of the mbuf allocator, which will
make it easier to refine the external storage mechanism without
disrupting drivers in the future.
- Reduce DPADD and LDADD in checkdpadd to -l<foo>
- Skip over -Wl,[es]*-group because -Wl,--end-group and

This caveat has been present for a while with some components of

after r269648.
Fix a boundary case error in vm_reserv_alloc_contig(): If a reservation
isn't being allocated for the last of the requested pages, because a
reservation won't fit in the gap between allocated pages, then the
reservation structure shouldn't be initialized.
Fix issue with nmdm and leading zeros in device name.
The nmdm code enforces a number between the 'nmdm' and 'A|B' portions
of the device name. This is then used as a unit number, and sprintf'd
back into the tty name. If leading zeros were used in the name,
the created device name is different than the string used for the
clone-open (e.g. /dev/nmdm0001A will result in /dev/nmdm1A).
Since unit numbers are no longer required with the updated tty
code, there seems to be no reason to force the string to be a
number. The fix is to allow an arbitrary string between
'nmdm' and 'A|B', within the constraints of devfs names. This allows
all existing user of numeric strings to continue to work, and also
allows more meaningful names to be used, such as bhyve VM names.
