GPIB overhaul, part #2: make the tnt4882 driver work with the newer
TNT5004 IC. This involved a major rewrite of a number of things, as
this chip no longer supports the NAT7210 legacy mode but requires the
host to use the (more modern) FIFO mode.
In theory, this also ought to work on the older TNT4882C chip. I'll
probably add this as optional support (perhaps by a device.hints flag)
later on. By now, FIFO mode is *only* activates iff a TNT5004 chip
has been detected (where the old code didn't work at all), while
everything else is supposed to use the old code.
- Add idempotency guards so the structures can be used in other utilities.
- Update bpb structs with reserved fields.
- In direntry struct join deName with deExtension. Although a
fix was attempted in the past, these fields were being overflowed,
Now this is consistent with the spec, and we can now share the
WinChksum code with NetBSD.
These fixes correct a problem in the file system that treats large
inode numbers as negative rather than unsigned. For a default
(16K block) file system, this bug began to show up at a file system
size above about 16Tb.
These fixes also update newfs to ensure that it will never create a
filesystem with more than 2^32 inodes.
They also update libufs, tunefs, and growfs so that they properly
handle inode numbers as unsigned.

On FreeBSD, time_t is 64-bit for all platforms except i386 and powerpc,
where the type is 32-bit. ZFS can handle 64-bit timestamp internally
but zfs_setattr() would check if the time value can fit, we change the
checking macros to match 64-bit timestamp if the platform supports it.
This change has some downsides like, while you can import zfs on 32-bit
platforms, the timestamp would overflow if they are out of the range.
This fixes the Y2.038K issue on platforms using 64-bit timestamps.

Replace the static NGROUPS=NGROUPS_MAX+1=1024 with a dynamic
kern.ngroups+1. kern.ngroups can range from NGROUPS_MAX=1023 to
somewhere in the neighborhood of INT_MAX/4 one a system with sufficent
RAM and memory bandwidth. Given that the Windows group limit is
1024, this range should be sufficient for most applications
r202342:
Only allocate the space we need before calling kern_getgroups instead
of allocating what ever the user asks for up to "ngroups_max + 1". On
systems with large values of kern.ngroups this will be more efficient.
The now redundant check that the array is large enough in
kern_getgroups() is deliberate to allow this change to be merged to
stable/8 without breaking potential third party consumers of the API.
Teach the (gpt)zfsboot and zfsloader raidz code to use its buffers

Before this patch, in the worst case memory use would increase

- Return EAFNOSUPPORT instead of EINVAL for unsupported address family,
this matches the Linux behavior.
- Check if we have sufficient space allocated for socket structure, which
fixes a buffer overflow when wrong length is being passed into the

- Move nfs_realign() from the NFS client to the shared NFS code and
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.
Optimize pmap_demote_pde() by using the new KPTmap to access a kernel
page table page instead of creating a temporary mapping to it.
Set the PG_G bit on the page table entries that implement the KPTmap.
Locore initializes the unused portions of the NKPT kernel page table
pages that it allocates to zero. So, pmap_bootstrap() needn't zero
the page table entries referenced by CMAP1 and CMAP3.
Simplify pmap_set_pg().
o Eliminate IA64_PHYS_TO_RR6 by calling bus_space_map() or pmap_mapdev().
o Implement bus_space_map() in terms of pmap_mapdev().

With FBS enabled, we have no idea what command caused timeout.

Change the default value for vfs.newnfs.enable_locallocks to 0 for
the experimental NFS server, since local locking is known to be
broken and the patch to fix it is still a work in progress.
This fixes the experimental NFS server so that it won't crash in the
caching code for IPv6 by fixing a typo that used the incorrect variable.
It also fixes the indentation of the statement above it.

Improve checking whether an ARM VA has a valid mapping before performing cache
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.
