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.
Fix mptutil's method for locating disk devices attached to a specific
mpt(4) controller. Previously, the code assumed that multiple match
patterns provided to an XPT_DEV_MATCH request were ANDed together.
Instead, they are ORed. Instead, to match peripherals for a specific bus,
one query needs to be performed to lookup the path ID of the bus. A second
query can then be performed matching peripherals attached to that path.
This approach also makes the code a bit cleaner as the returned match
results do not mix buses and perphierals.
- Don't emit a warning in 'show adapter' if the IOC2 or IOC6 pages are not
present. mpt(4) controllers that do not support RAID do not have an IOC6
page, for example.
- Correct a check for a missing page error in a debug function.
Fixes for ls(1) long format (-l) output:
- Allow -h option to work if the listing contains at least one device
file.
- Align major and minor device numbers correctly to the size field.

- 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().
o Have ia64_pib hold the uncached virtual address of the PIB.

Change the default value for vfs.newnfs.enable_locallocks to 0 for

This fixes the experimental NFS server so that it won't crash in the

It also fixes the indentation of the statement above it.
