99ab4b1297 Permit changing MTU in 6to4 relay.
This behavior is recommended by RFC 4213 clause 3.2.

Sometimes fragmentation is the least evil.
For example, some Linux IPVS kernels forwards
ICMPv6 checksums to real servers incorrectly.

without a PHY, so I implemented non-PHY support in the udav driver.

333d0c6060 Add support for the XSAVEOPT instruction use. Our XSAVE/XRSTOR usage
mostly meets the guidelines set by the Intel SDM:
1. We use XRSTOR and XSAVE from the same CPL using the same linear
   address for the store area
2. Contrary to the recommendations, we cannot zero the FPU save area
   for a new thread, since fork semantic requires the copy of the
   previous state. This advice seemingly contradicts to the advice
   from the item 6.
3. We do use XSAVEOPT in the context switch code only, and the area
   for XSAVEOPT already always contains the data saved by XSAVE.
4. We do not modify the save area between XRSTOR, when the area is
   loaded into FPU context, and XSAVE. We always spit the fpu context
   into save area and start emulation when directly writing into FPU
   context.
5. We do not use segmented addressing to access save area, or rather,
   always address it using %ds basing.
6. XSAVEOPT can be only executed in the area which was previously
   loaded with XRSTOR, since context switch code checks for FPU use by
   outgoing thread before saving, and thread which stopped emulation
   forcibly get context loaded with XRSTOR.
7. The PCB cannot be paged out while FPU emulation is turned off, since
   stack of the executing thread is never swapped out.

The context switch code is patched to issue XSAVEOPT instead of XSAVE
if supported. This approach eliminates one conditional in the context
switch code, which would be needed otherwise.

For user-visible machine context to have proper data, fpugetregs()
checks for unsaved extension blocks and manually copies pristine FPU
state into them, according to the description provided by CPUID leaf
0xd.

0b59717b4b Change the RX EDMA path to first complete the FIFO, then re-populate it
with fresh descriptors, before handling the frames.

Wrap it all in the RX locks.

Since the FIFO is very shallow (16 for HP, 128 for LP) it needs to be
drained and replenished very quickly.  Ideally, I'll eventually move this
RX FIFO drain/fill into the interrupt handler, only deferring the actual
frame completion.

39abbd9bd2 Fix EDMA RX to actually work without panicing the machine.
I was setting up the RX EDMA buffer to be 4096 bytes rather than the
RX data buffer portion.  The hardware was likely getting very confused
and DMAing descriptor portions into places it shouldn't, leading to
memory corruption and occasional panics.

Whilst here, don't bother allocating descriptors for the RX EDMA case.
We don't use those descriptors. Instead, just allocate ath_buf entries.

2919668490 Make the interval timings for EVFILT_TIMER more accurate. tvtohz() always
adds an extra tick to account for the current partial clock tick.  However,
that is not appropriate for a repeating timer when the exact tvtohz() value
should be used for subsequent intervals.  Fix repeating callouts for
EVFILT_TIMER by subtracting 1 tick from the tvtohz() result similar to the
fix used in realitexpire() for interval timers.

While here, update a few comments to note that if the EVFILT_TIMER code
were to move out of kern_event.c, it should move to kern_time.c (where the
interval timer code it mimics lives) rather than kern_timeout.c.

d30b88af05 acpi_cpu: separate a notion of current deepest allowed+available Cx level
... from a user-set persistent limit on the said level.
Allow to set the user-imposed limit below current deepest available level
as the available levels may be dynamically changed by ACPI platform
in both directions.
Allow "Cmax" as an input value for cx_lowest sysctls to mean that there
is not limit and OS can use all available C-states.
Retire global cpu_cx_count as it no longer serves any meaningful
purpose.

a68d1f48b9 Complete the transition away from newbus to populate the children to
the linker set of CPU modules.  The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful.  delay and cpu_reset now work much earlier in the
boot process.
