ifconfig: Do not build geneve with WITHOUT_NETLINK_SUPPORT

powerpc/intr setup: Don't check intr name for IPI
Since whether or not the irq is an IPI is passed into
powerpc_setup_intr_int(), use this as the check for IPI instead of
checking the name string.
powerpc/pmap: Add support for page sizes found on E6500
E6500 cores (MMUv2) support all powers-of-2 page sizes from 4k to 1TB,
not just powers of 4. By using the other page sizes (8k, 32k, etc) we
can save on TLB1 space, saving up to ~1/3 of used TLB1 entries.

nd6: Add support for route information (RFC 4191)
Implement RFC 4191 by handling received Router Adverisement (RA)
packets with route information option.
For default routes, use the route information's lifetime and
preference to overwrite the RA's lifetime/preference.
Also install and update more-specific route prefixes with the
option's lifetime and expire them when their lifetime elapses.

stand/libofw: make OF_hasprop() part of the library
Currently it is only needed by powerpc ofwfdt.c, and defined statically
there. Make it available as part of libofw, mirroring what we have in
the kernel.
Two small tweaks are made to the implementation:
1. Return type is changed to bool
2. Return 'true' when OF_getproplen() == 0. This matches the expected
semantics of the kernel version, described in OF_hasprop(9).

pkru.3: Note that the kernel may not respect PKRU protections
There are cases where the kernel will be able to access memory covered
by a PKRU key which nomially prohibits accesses. I believe regular
copyin()/copyout() are subject to the contents of PKRU, but memory
accesses via uiomove_fromphys() will not be. This can arise when
performing fault I/O, for instance. I didn't test, but I suspect AIO is
another case.
Update the man page to acknowledge this.

pkru.3: Remove a qualifier
Now that i386 kernels are deprecated, we don't really need to mention

mlx5e: Ensure rx timestamps are monotonically increasing
The clock calibration routine currently can result in rx timestamps
jumping backwards, which can confuse the TCP stack.
Ensure they are monotonically increasing by estimating what
we'd calculate as the next timestamp and clamp the calibration
so new timestamps are no earlier in time.

raspberry_virtgpio: fix OF_hasprop() usage
The function returns a bool. This driver was merged recently (by me) and
I missed this instance.
While here, adjust the ofw_bus_status_okay() call similarly. This
function still returns an int, but this usage is more widely used in our
drivers.
No functional change intended.

pmap: Do not use PMAP_LOCK_INIT with kernel_pmap
The kernel_pmap lock is a bit special: it does not need the DUPOK flag,
and it really belongs to a different lock class. If it belongs to the
same class as regular pmap locks, then witness may report warnings when
performing UMA allocations under a regular pmap lock, if the allocation
triggers a pmap_growkernel() call.
Replace instances of PMAP_LOCK_INIT(kernel_pmap) with inline mtx_init()
calls to silence some witness warnings for harmless behaviour I see with
some uncommitted test programs.

imgact_elf: Unconditionally initialize a variable in a note handler
In the sb == NULL case, we are computing the size of the note using a
dummy sbuf drain handler which counts bytes and discards the contents of
the buffer, so the fact that "structsize" is uninitialized doesn't
matter. But, the compiler may complain about this, so we might as well
just initialize it unconditionally to silence the warning, as other
handlers already do.
