nd6: Add router address and DHCPv6-PD flags in PIO headers
Make R-bit per RFC 6275 8.3 and P-bit per RFC 9762 7.1 in
Prefix Information option available to userland for future implementations.
RFC 9762 7.1: For each interface, the client MUST keep a list of every prefix
that was received from a PIO with the P flag set and currently has a non-zero
preferred lifetime.

acpi_cpu(4): Call ACPI_GET_FEATURES() on a reset 'features' variable
This is to prevent child drivers from using the features returned by
previous drivers (in an arbitrary order). None of the existing ones do
that, so this is purely defensive.

linker: Recognize SHT_INIT_ARRAY sections as constructor sections
We do this already for ET_REL files, but it was missed here. Note that
this function operates only on dynamically loaded files, not on
preloaded files.

stand: Recognize SHT_INIT_ARRAY sections as constructor sections
Pass such a section to the kernel using modinfo, otherwise link_elf.c
won't execute constructors for the file. This is required for KASAN,
otherwise redzones for global buffers are not poisoned during boot.

pfctl: fix incorrect errno checks
These calls return an error value, they do not set errno. Check their

mbuf: make m_unshare() allow unmapped mbufs
m_unshare() had crashed if unmapped mbufs exist in the mbuf chain.
This was because memcpy() with mtod() was used without making sure that
the mbuf was mapped. Use m_copydata() that cares unmapped mbufs instead.

virtio: Accept VIRTIO_F_RING_RESET in the modern PCI transport
Accept per-virtqueue reset when the device offers it, alongside
the V1 flag. Negotiating the feature merely permits the use of
per-virtqueue reset and imposes no obligation on a driver that
never uses it, while refusing capability-only transport features
can make strict devices reject the feature set altogether.
No functional change on hosts that do not offer RING_RESET.

fibs_test: Mark same_ip_multiple_ifaces_fib0 as expected to fail
The test relies on being able to assign the same interface address to
two different tap interfaces; it then removes one of the addresses,
which at one point would trigger a kernel panic.
Since 361a8395f0b0 it is not possible to assign an address multiple
times this way, so the test fails. Just mark it as expected to fail for
now: if the kernel's behaviour here changes again, this test might be a
useful seatbelt.

accept_filter: return different errors for non-listener and a busy socket
The fact that an accept filter needs to be cleared first before setting to
a different one isn't properly documented. The requirement that the
socket needs already be listening, although trivial, isn't documented
either. At least return a more meaningful error than EINVAL for an
existing filter. Cover this with a test case.

netinet6: Remove ndpr_raf_ra_derived flag
This flag was introduced at 8036234c72c9361711e867cc1a0c6a7fe0babd84
to prevent the SIOCSPFXFLUSH_IN6 ioctl from removing manually-added
entries. However, this flag did actually not work due to an
incomplete implementation making prelist_update() not handle it before
calling nd6_prelist_add().
This patch removes the flag because a prefix is derived from an RA
always has an entry in the ndpr_advrtrs member in the struct
nd_prefix. Having a separate flag is not a good idea because it can
cause a mismatch between the flag and the ndpr_advrtrs entry. Testing
using LIST_EMPTY() is simpler for the origial goal.
This also removes in a prefix check in the ICMPV6CTL_ND6_PRLIST sysctl
to exclude manually-added entries. This ioctl is designed to list all
entries, and there is no relationship to SIOCSPFXFLUSH_IN6.
