Since no WORLDTMP/usr/bin/cc is created, cc cannot be found
during installworld time since /usr/bin is not in the PATH.
Pass along the known compiler metadata to allow installworld
to work. The same fix was used for WITH_SYSTEM_COMPILER.
A better route would be to store a cookie in buildworld
containing this compiler metadata and then using that
at install time, rather than rerunning cc.

Ccache will not affect the output of the objects, so just ignore it for
meta mode handling. This avoids having everything rebuild if ccache is
updated.

The first file in these lists will generate everything else so only
it should be getting a .meta file. With bmake's missing=yes meta
feature these would otherwise cause a rebuild without the
.NOMETA hint.

This breaks cross-building with WITH_META_MODE since it will rebuild
'build-tools' during the 'everything' phase.
A more proper fix is coming to bmake to implicitly require .META unless
.NOMETA (and other restrictions) are in place.

Bus space methods are not called so simple pmap_mapdev will suffice.

Reduce number of iterations used for calibrating ICR read loop. The
new number of iteration still gives the same ICR latency as before,
tested on Intel SandyBridge and Haswell machines, and on AMD. But it
significantly reduces the unneeded pause on boot in some VMs, from ~10
secs to less then 1 sec. It was reported to occur in bhyve on AMD
host.

This is a followup to r300131.
A filesystem's root vnode can be reached not only through VSF_ROOT, but
by other means as well. For example, via a dot-dot lookup.
Also, a root vnode can get reclaimed and then re-created. For these
reasons it was insufficient to clear VV_ROOT flag from a root vnode of a
snapshot mounted under .zfs in zfsctl_snapdir_lookup().
So, now we set the flag in zfs_znode_sa_init() only if a vnode
represent a root of a filesystem or a standalone snapshot.
That is, the flag is not set for snapshots mounted under .zfs.

Add accessor functions to toggle the state per VNET.
The base system (vnet0) will always enable itself with the normal

The current error path in case of failure during attach/initialization is
not correct and leaves blkback in a stuck state. This is due to blkback
waiting for blkfront to switch to state XenbusStateClosed, but if blkfront
never attached (because the guest is not even started) it cannot possibly
make it to that state.
Instead just wait for the frontend to be in a state different than
XenbusStateConnected in order to proceed with the shutdown. Also, it is
wrong to call xbb_detach directly because it destroys the lock which can
still be used by xbb_frontend_changed.

Hotplug scripts are needed in order to use fancy disk configurations in xl,
like iSCSI disks. The job of hotplug scripts is to locally attach the disk
and present it to blkback as a block device or a regular file.
This change introduces a new xenstore node in the blkback hierarchy, called
"physical-device-path". This is a straigh replacement for the "params" node,
which was used before.
Hotplug scripts will need to read the "params" node, perform whatever
actions are necessary and then write the "physical-device-path" node. The
hotplug script is also in charge of detaching the disk once the domain has
been shutdown.

controller devices are attached. This has already been done for
bus_setup_intr().
There was no doubt that if someone wants to setup an interrupt,
corresponding interrupt controller device must already be attached.
However, the same must be valid for allocation of an interrupt resource
unless the allocation is done blindly, without any information that
such interrupt even exists. While it was done this blind way before,
it won't be possible after next INTRNG change.
framework has significantly changed the driver has moved to a new file.
While it shares some code with the existing driver this has been modified
to work better with the intrng framework.
This has been tested on the ThunderX servers in the netperf cluster and has
been used to boot them for other testing, including DTrace and hwpmc.
With this we can use intrng on all supported arm64 platforms I was able to
test on. It is expected we will move to intrng soon, and disable the old
arm64 interrupt framework.

range of interrupts they pass to a second controller driver to handle.
The parent driver is expected to detect when one of these interrupts has
been triggered and call intr_child_irq_handler to pass the interrupt to
a child. The children controllers are then expected to manage the range
by allocating interrupts as needed.
This will initially be used by the ARM GICv3 driver, but is is expected to
be useful for other driver where this type of allocation applies.

Replacing the bubble sort with insertion sort gives an 80% reduction
in runtime on average, with randomized keys, for small partitions.
If the keys are pre-sorted, insertion sort runs in linear time, and
even if the keys are reversed, insertion sort is faster than bubble
sort, although not by much.

Only attempt to detect AVG if SSE2 is available
Summary:
In PR29973 Sanjay Patel reported an assertion failure when a certain
loop was optimized, for a target without SSE2 support. It turned out
this was because of the AVG pattern detection introduced in rL253952.
Prevent the assertion failure by bailing out early in
`detectAVGPattern()`, if the target does not support SSE2.
Also add a minimized test case.

TDMA and CESA registers are placed in different ranges of memory. Split
memory resource in DTS to reflect that. This change is needed to support
multiple CESA nodes as otherwise the ranges of different nodes would
overlap.
In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have
been modified as the base address has changed.
