The ADD, AND, OR, and SUB instructions take at most a 32-bit
sign-extended immediate operand. 64-bit constants that do not fit into
that constraint need to be loaded into a register. The 'i' constraint
tells the compiler it can pass any integer constant to the assembler,
whereas the 'e' constrain only permits constants that fit into a 32-bit
sign-extended value. This fixes using
atomic_add/clear/set/subtract_long/64 with constants that do not fit into
a 32-bit sign-extended immediate.

Some example files:
ia32_genassym.o
acpi_wakecode.o
The old mkdep method also lacked tracking these files.
Objects defined in sys/conf/files with no-obj and no-implicit-rule get their
own targets defined in the kernel Makefile but lack having their objects added
to DEPENDOBJS so never get a .depend file generated. Normally if an object is
in OBJS it will get a .depend file.
Fix this by looking for .o files in CLEAN and ensuring they are part of
the -MD filtering and .depend loading. This is a hack. Other solutions
could exist involving sys/conf/files or config(8) to auto add these to
DEPENDFILES/DEPENDOBJS but this method seems reliable enough without being
intrusive or error-prone for new files.

Fix possible strict aliasing issue (if time_t is the same size as int but
not int but for example long) which also resulted in a false positive
warning on systems with 64-bit time_t. Pointer casts are bad; we can just
copy the time_t.
Elsewhere, avoid casting char * to int * by using memcpy().

auditd_wait_for_events() relies on read(2) being interrupted by signals,
but it registers signal handlers with signal(3), which sets SA_RESTART.
That breaks asynchronous signal handling. It means that signals don't
actually get handled until after an audit(8) trigger is received.
Symptoms include:
* Sending SIGTERM to auditd doesn't kill it right away; you must send
SIGTERM and then send a trigger with auditon(2).
* Same with SIGHUP
* Zombie child processes don't get reaped until auditd receives a trigger
sent by auditon. This includes children created by expiring audit trails
at auditd startup.
Fix by using sigaction(2) instead of signal(3).

- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: <tag>' for strings
referencing the version of the source file copied from in the license
block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
each checkout. Fix those to hardcode the FreeBSD tag from the file that
was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from
OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
CSRG -> OtherBSD -> FreeBSD.

This is in preparation for changes to update the various ID strings in
libc's source. CSRG ID strings will use __SCCSID() and there are some
existing uses of __RCSID() for NetBSD ID strings already. These are
generally under either an explicit #if 0 or an #ifdef LIBC_SCCS so are
off by default and this change preserves that existing behavior.

ACFLAGS is only used in addition to CFLAGS, so setting the options in
both was redundant. However, ACFLAGS is added to the command line
after CFLAGS, so the settings from ACFLAGS were applied for assembly
files in kernel modules after the kernel-specific march/abi in CFLAGS.
As a result, the hard-float ACFLAGS in bsd.cpu.mk was overriding the
soft-float CFLAGS.gcc in sys/conf/kern.mk. In particular,
dtrace_asm.o was compiled as hard-float and the linker refused to link
dtrace.ko since its object files contained a mix of hard and soft
float.

An example of this is, when the "m" command is entered, the title line

Avoid pulling in all of the <sys/proc.h> dependencies by
automatically generating a stripped down thread_lite exporting
only the fields of interest. The field declarations are type checked
against the original and the offsets of the generated result is
automatically checked.
kib has expressed disagreement and would have preferred to simply
use genassym style offsets (which loses type check enforcement).
jhb has expressed dislike of it due to header pollution and a
duplicate structure. He would have preferred to just have defined
thread in _thread.h. Nonetheless, he admits that this is the only
viable solution at the moment.
The impetus for this came from mjg's D15331:

This is purely to make it easier to tweak them locally; the machine I have
for testing takes forever to do 50,000 pw strengthening iterations, and
we're not testing the strength of geli's anti-pw-guessing logic here
(especially given that our test passphrase is "passphrase", except that
I tend to tweak that also, to 'x', because typing is hard).
Some day these should be settable as cmdline args. But then, some day this
whole script should probably get a rewrite. :)
Previously the code cut those fields on second colon, that prevented
boot from boot environments with colon in their names. This change
moves the limitation from dev field to path, which is empty by default.

r335871 added support for an optional suffix of "#mds_path" that can be

the DS should be used to store files for the file system on the MDS

This patch documents this optional suffix.
This is a content change.
Without this patch, the pNFS server distributes the data storage files across
all of the specified DSs.
A tester noted that it would be nice if a system administrator could control
which DSs are used to store the file data for a given exported MDS file system.
This patch adds an optional suffix for each entry in the "-p" option argument

The interface between the nfsd and the kernel has changed with this patch,

This patch adds the kernel support to do this. It also makes a slight semantic
change to nfsv4_findmirror(), since some uses of it no longer require that
the DS being searched for have a current mirror.
A patch that will be committed in a few minutes will modify the nfsd daemon

If a disk is of an oddball size, like the 200mb + 512b used in rootgen.sh,
when disk_open() is called on a GELI encrypted partition, attempts to read
the partition table fail, as they pass through the decryption process which
turns the already plaintext data into jibberish.
When reading the partition table, always pass a slice and partition setting
of -1, and an offset of 0. Setting the slice to -1 prevents a false
positive when checking the slice against the cache of GELI encrypted
slices.

Occationally the kernel nfsd threads would not terminate when a SIGKILL
was posted for the kernel process (called nfsd (slave)). When this occurred,
the thread associated with the process (called "ismaster") had returned from
svc_run_internal() and was sleeping waiting for the other threads to terminate.
The other threads (created by kthread_start()) were still in svc_run_internal()
handling NFS RPCs.
The only way this could occur is for the "ismaster" thread to return from
svc_run_internal() without having called svc_exit().
There was only one place in the code where this could happen and this patch
stops that from happening.
Since the problem is intermittent, I cannot be sure if this has fixed the
problem, but I have not seen an occurrence of the problem with this patch
applied.
