Now consumers of KPI do not need to re-lookup the pages after call to

Note that the upstream commit is modified during MFV: in the upstream
the check is done by inspecting ds_is_snapshot field while in FreeBSD
we call dsl_dataset_is_snapshot().
This is because illumos/illumos-gate@bc9014e6a8
(r277428 in vendor-sys/illumos) is not MFV-ed yet.

0. For spin events report time spent spinning, not a loop count.
While loop count is much easier and cheaper to obtain it is hard
to reason about the reported numbers, espcially for adaptive locks
where both spinning and sleeping can happen.
So, it's better to compare apples and apples.
1. Teach lockstat about FreeBSD rw locks.
This is done in part by changing the corresponding probes
and in part by changing what probes lockstat should expect.
2. Teach lockstat that rw locks are adaptive and can spin on FreeBSD.
3. Report lock acquisition events for successful rw try-lock operations.
4. Teach lockstat about FreeBSD sx locks.
Reporting of events for those locks completely mirrors
rw locks.
5. Report spin and block events before acquisition event.
This is behavior documented for the upstream, so it makes sense to stick
to it. Note that because of FreeBSD adaptive lock implementations
both the spin and block events may be reported for the same acquisition
while the upstream reports only one of them.

The FreeBSD extension adds a new request type, called blkif_segment_block
which has a size of 112bytes for both i386 and amd64. This is fine on
amd64, since requests have a size of 112B there also. But this is not true
for i386, where requests have a size of 108B. So on i386 we basically
overrun the ring slot when queuing a request of type blkif_segment_block_t,
which is very bad.
Remove this extension (including a cleanup of the public blkif.h header
file) from blkfront and blkback.

This target mainly exists to help check things build.
Eventually targets that build real packages or images will be more
important.
As such move the pseudo targets that only exist for the benefit of
'userland' to under it.
We don't use the direction of the fragments for anything. The frc_direction
field is assigned, but never read.
Just remove it.

drivers, one for fdt, one for acpi. It then uses this to decide if it will
use fdt or acpi.
The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.
As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.

multiple of the cylinder size. This is what qemu-img seems to
be doing. Make sure to handle boundary cases where increasing
the image size by 1 cyclinder's worth would also result in a
change of geometry.
When we try to look up a pf_fragment with pf_find_fragment() we compare (see
pf_frag_compare()) addresses (and family), id but also protocol. We failed to
save the protocol to the pf_fragment in pf_fragcache(), resulting in failing
reassembly.

Do not include machine/atomic.h explicitely, the header is already included
by sys/systm.h.
Force inlining of tc_getgen() and tc_setgen(). The functions are used
more than once, which causes compilers with non-aggressive inlining
policies to generate calls.

In TCP timer context, it is not enough to check callout_stop() return value
to decide if a callout is still running or not, previous callout_reset()
return values have also to be checked.
