remove the NFS server version in order to reduce code duplication.
The shared version now uses a second parameter how, which is passed
on to m_get(9) and m_getcl(9) as the server used M_WAIT while the
client requires M_DONTWAIT, and replaces the the previously unused
parameter hsiz.
- Change nfs_realign() to use nfsm_aligned() so as with other NFS code
the alignment check isn't actually performed on platforms without
strict alignment requirements for performance reasons because as the
comment suggests unaligned data only occasionally occurs with TCP.
- Change fha_extract_info() to use nfs_realign() with M_DONTWAIT rather
than M_WAIT because it's called with the RPC sp_lock held.

interfaces (such as when you are part of a carp pool), and you run
rpcbind -h to restrict which interfaces have rpc services, rpcbind can
none-the-less return addresses that aren't in the -h list. This patch
enforces the rule that when you specify -h on the command line, then
services returned from rpcbind must be to one of the addresses listed
in -h, or be a loopback address (since localhost is implicit when
running -h).
The root cause of this is the assumption in addrmerge that there can
be only one interface that matches a given network IP address. This
turns out not to be the case. To retain historical behavior, I didn't
try to fix the routine to prefer the address that the request came
into, since I didn't know the side effects that might cause in the
normal case. My quick analysis suggests that it wouldn't be a
problem, but since this code is tricky I opted for the more
conservative patch of only restricting the reply when -h is in effect.
Hence, this change will have no effect when you are running rpcbind
without -h.

annotate the sockaddr structs to communicate this to the compiler and
there's a number of constructs in the tree that make this annotation
challenging.
As such, reduce warns to 3 here because this code really isn't warns 6

sync.
VIPT/PIPT caches need valid VA-PA mapping in PTE for a cache operation to
succeed (unlike VIVT). Prior to this fix pmap was using l2pte_valid() for that
check, but this is not sufficient as the function merely checks if a PTE
exists (there can be existing but _invalid_ entries in the table).
A new pmap_has_valid_mapping() routine is introduced to do this job right by
checking proper PTE flags.
Among other potential problems this cures coherency issues with L2 caches on
MV-78100.
