r320062 introduced a bug when doing NFSv4.1 mounts against some non-FreeBSD servers.
r320062 used nm_rsize, nm_wsize to set the maximum request/response sizes for
the NFSv4.1 session. If rsize,wsize are not specified as options, the
value of nm_rsize, nm_wsize is 0 at session creation, resulting in
values for request/response that are too small.
This patch fixes the problem. A workaround is to specify rsize=N,wsize=N
mount options explicitly, so they are set before session creation.
This bug only affects NFSv4.1 mounts against some non-FreeBSD servers.

Change blist_alloc()'s allocation policy from first-fit to next-fit so
that disk writes are more likely to be sequential. This change is
beneficial on both the solid state and mechanical disks that I've
tested. (A similar change in allocation policy was made by DragonFly
BSD in 2013 to speed up Poudriere with "stressful memory parameters".)
Increase the width of blst_meta_alloc()'s parameter "skip" and the local
variables whose values are derived from it to 64 bits. (This matches the
width of the field "skip" that is stored in the structure "blist" and
passed to blst_meta_alloc().)
Eliminate a pointless check for a NULL blist_t.
Simplify blst_meta_alloc()'s handling of the ALL-FREE case.
Address nearby style errors.
MFC r320417
Address the remaining integer overflow issues with the "skip" parameters
and "next_skip" variables. The "skip" value in struct blist has long been
a 64-bit quantity but various functions have implicitly truncated this
value to 32 bits. Now, all arithmetic involving the "skip" value is 64
bits wide. (This should allow us to relax the size limit on a swap device
in the swap pager.)
Maintain the ability to test this allocator as a user-space application by
including <stdbool.h>.
Remove an unused variable from blst_radix_print().
MFC r320527
Change blst_leaf_alloc() to handle a cursor argument, and to improve
performance.
To find in the leaf bitmap all ranges of sufficient length, use a doubling
strategy with shift-and-and until each bit still set represents a bit
sequence of length 'count', or until the bitmask is zero. In the latter
case, update the hint based on the first bit sequence length not found to
be available. For example, seeking an interval of length 12, the set bits
of the bitmap would represent intervals of length 1, then 2, then 3, then
6, then 12. If no bits are set at the point when each bit represents an
interval of length 6, then the hint can be updated to 5 and the search
terminated.
If long-enough intervals are found, discard those before the cursor. If
any remain, use binary search to find the position of the first of them,
and allocate that interval.
Fix spurious timeouts on commands sent to mps(4) and mpr(4) controllers.
mps_wait_command() and mpr_wait_command() were using getmicrotime() to
determine elapsed time when checking for a timeout in polled mode.
getmicrotime() isn't guaranteed to monotonically increase, and that
caused spurious timeouts occasionally.
Switch to using getmicrouptime(), which does increase monotonically.
This fixes the spurious timeouts in my test case.
- Document /etc/cron.d and /usr/local/etc/cron.d under FILES.
- Reword documentation for -n: add appropriate soft-stop and remove
contraction to appease igor.
Reduce the frequency of hint updates on allocation without incurring
additional allocation overhead. Previously, blst_meta_alloc() updated the
hint after every successful allocation. However, these "eager" hint
updates are of no actual benefit if, instead, the "lazy" hint update at
the start of blst_meta_alloc() is generalized to handle all cases where
the number of available blocks is less than the requested allocation.
Previously, the lazy hint update at the start of blst_meta_alloc() only
handled the ALL-FULL case. (I would also note that this change provides
consistency between blist_alloc() and blist_fill() in that their hint
maintenance is now entirely lazy.)
Eliminate unnecessary checks for terminators in blst_meta_alloc() and
blst_meta_fill() when handling ALL-FREE meta nodes.
Eliminate the field "bl_free" from struct blist. It is redundant. Unless
the entire radix tree is a single leaf, the count of free blocks is stored
in the root node. Instead, provide a function blist_avail() for obtaining
the number of free blocks.
In blst_meta_alloc(), perform a sanity check on the allocation once rather
than repeating it in a loop over the meta node's children.
In blst_leaf_fill(), use the optimized bitcount*() function instead of a
loop to count the blocks being allocated.
MFC r320546
When "force" is specified to pmap_invalidate_cache_range(), the given
start address is not required to be page aligned. However, the loop
within pmap_invalidate_cache_range() that performs the actual cache
line invalidations requires that the starting address be truncated to
a multiple of the cache line size. This change corrects an error in
that truncation.
MFC r320498
Clear the MAP_WIREFUTURE flag on the vm map in exec_new_vmspace() when it
recycles the current vm space. Otherwise, an mlockall(MCL_FUTURE) could
still be in effect on the process after an execve(2), which violates the
specification for mlockall(2).
It's pointless for vm_map_stack() to check the MEMLOCK limit. It will
never be asked to wire the stack. Moreover, it doesn't even implement
wiring of the stack.

Add newsyslog capability to write RFC5424 compliant rotation message.
This modification adds the capability to newsyslog to write the
rotation message in a format that is compliant with RFC5424. This
capability is enabled on a per-log file basis through a new value
("T") in the flags field in newsyslog.conf. This is useful on systems
that use the RFC5424 format for log files so that the rotation message
format matches that of the other log messages. There has been recent
mention of adding an RFC5424 compliant mode to syslogd and at least
one alternative system log daemon (rsyslogd) that already has the
capability to use that format.

savecore: fix space calculation with respect to `minfree` in check_space(..)

- Use `KiB` instead of `kB` when describing free space, total space,
etc. I am now fully aware of `KiB` being the IEC standard for 1024
bytes and `kB` being the IEC standard for 1000 bytes.
- Store available number of KiB in `available` so it can be more
easily queried and compared to ensure that there are enough KiB to
store the dump image on disk.
- Print out the reserved space on disk, per `minfree`, so end-users
can troubleshoot why check_space(..) is reporting that there isn't
enough free space.

a large degree of dislike with IEC vs more SI-like units.
