Move the ZERO_REGION_SIZE to a machine-dependent file, as on many

2011-05-13T19:35:01+00:00

architectures (i386, for example) the virtual memory space may be
constrained enough that 2MB is a large chunk.  Use 64K for arches
other than amd64 and ia64, with special handling for sparc64 due to
differing hardware.

Also commit the comment changes to kmem_init_zero_region() that I
missed due to not saving the file.  (Darn the unfamiliar development
environment).

Arch maintainers, please feel free to adjust ZERO_REGION_SIZE as you
see fit.

This patch changes head so that the default NFS client is now the new

2011-04-27T17:51:51+00:00

NFS client (which I guess is no longer experimental). The fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, an updated mount_nfs(8) binary is needed for kernels built with
"options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and
mount(8) binaries are needed to do mounts for fstype "oldnfs".
The GENERIC kernel configs have been changed to use options
NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER.
For kernels being used on diskless NFS root systems, "options NFSCL"
must be in the kernel config.
Discussed on freebsd-fs@.

Switch the GENERIC kernels for all architectures to the new CAM-based ATA

2011-04-24T08:58:58+00:00

stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.

Correct spelling in comments.

r216801

- cosmetic changes and style fixes
- Trick GAS/GCC into compiling access to TICK/(S)TICK_COMPARE independently
  of the selected instruction set. Moreover, sun4v doesn't need the WAR for
  BlackBird CPUs.
- Rename the "xor" parameter to "xorval" as the former is a reserved keyword
  in C++.

Remove the advertising clause from the UCB license according to the

Sync licenses and the corresponding RCS IDs with NetBSD, mainly switching

Mostly revert r219468, as I had misremembered the C standard regarding

2011-03-11T18:56:55+00:00

the size of an extern array.

Keep one change from strncpy to strlcpy.

Use MAXPATHLEN rather than the size of an extern array when copying the

2011-03-10T22:56:00+00:00

kernel name.  Also consistenly use strlcpy().
