Fix a number of warnings. A gcc preprocessor bug relating to macros
with variable numbers of arguments made this slightly harder than
it should be. Avoid the bug by not doing string concatenation within
the macros, and instead add a new function to syslog or print the
error messages.
o Introduce and use vm_map_trylock() to replace several direct uses
of lockmgr().
o Add missing synchronization to vmspace_swap_count(): Obtain a read lock
on the vm_map before traversing it.
Add code to emulate arithmetic, comparison and conversion operations
on long double, which are not implemented in hardware on any UltraSPARC
chip that I know of. This just calls into the existing floating point
emulator, which is still needed to emulate other floating point operations
in certain conditions. Without this gcc has to generate the quad floating
point instructions directly, which sometimes causes internal compiler
errors.
Add many prototypes and ANSI-ize 'patch. Not a complete job of it, but it gets
our patch to look a little more like NetBSD's, and has the nice characteristic
that the object code is exactly the same after the change as before it (even in
patch.c and pch.c, which have pesky 'assert' statements in them).

We do not necessarily need to map/unmap pages to zero parts of them.
On systems where physical memory is also direct mapped (alpha, sparc,
ia64 etc) this is slightly harmful.
Avoid the user-visible effect of setting SA_NOCLDWAIT when the
SIGCHLD handler is SIG_IGN. This is a reimplementation of the
problematic revision 1.131 of kern_exit.c. To avoid accessing process
UPAGES, we set a new procsig flag when the SIGCHLD handler is SIG_IGN
and use that instead.

Finish fixing hints. Remember the use_kenv state for the next run.
Otherwise we fall back to using the static hints the next time around.
We still have the leftover fallback code there which meant that we skipped
the use_hints checking on the second and subsequent calls. Also, be a bit
more careful about walking off the end of the envp array.
I've extracted this from a larger diff. I hope I didn't miss anything...
Remove a stale comment saying that the vnode lock must be the first
element in the structure pointed to by vp->v_data; the vnode lock
is now within the vnode structure itself.
Remove the nfs_{lock,unlock,islocked} functions and the associated
definitions; they have been unused and #if 0'd out since the Lite/2
merge and we are unlikely to want them in the future.
o Begin documenting the (existing) locking protocol on the vm_map
in the same style as sys/proc.h.
o Undo the de-inlining of several trivial, MPSAFE methods on the vm_map.
(Contrary to the commit message for vm_map.h revision 1.66 and vm_map.c
revision 1.206, de-inlining these methods increased the kernel's size.)
Emulate ldq and stq (load/store long double) instructions. GCC has started
using these to load long doubles, but they aren't implemented in hardware
on (at least) UltraSPARC I and II machines.
Emulate popc in the user trap handler as well.
Re-arrange slightly to make support functions more accessible.
This patch fixes my breakage of ssid matching. I introduced the
breakage when I tried to merge OpenBSD wi_hostap changes into the
tree. Skibo found the problem and submitted these patches. Thanks!
Better names for the PCI cards. The biggest change is that we now
identify the Intersil Prism 2.5 PCI native card as that, rather than
Linksys, the first folks to get it to market.
Add a global sx sigio_lock to protect the pointer to the sigio object
of a socket. This avoids lock order reversal caused by locking a
process in pgsigio().
sowakeup() and the callers of it (sowwakeup, soisconnected, etc.) now
require sigio_lock to be locked. Provide sowwakeup_locked(),
soisconnected_locked(), and so on in case where we have to modify a
socket and wake up a process atomically.
Fix handling of weak references to undefined symbols on ia64:
o Set st_shndx for sym_zero to SHN_UNDEF instead of SHN_ABS.
This gives us something to reliably test against.
o For weak references to undefined sysmbols (as indicated by
having st_shndx equals SHN_UNDEF) in the context of OPDs,
the address of the OPD is to be zero, not the address of
the function it contains.
o For weak references to undefined symbols in all other cases
(only DIR64LSB at this time), the actual relocated value is
to be zero, not the value prior to relocating.
Roughly speaking, weak references to undefined symbols are no-ops.
Don't do symbol lookups for local symbols. The symbol index in the
relocation identifies the symbol to which we need to bind. This
solves a problem seen on ia64 where the symbol hash table does not
contain local symbols and thus resulted in unresolved symbols.
Add a CAM interface to the aac driver. This is useful in case you should
ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper
to your high-end RAID controller. The interface to the arrays is still
via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly. Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver. Be the first on your block to low-level format unsuspecting
drives that are part of an array!
To enable this, add the 'aacp' device to your kernel config.
Rename the file used to specify the nextboot to make it clear that this
is a loader configuration file and can be used for more than just a
kernel name.
A long, long time ago, msmith introduced vfs.root.mountfrom
loader variable, which let users specify the root mount point
the exact way one does after booting the kernel.
Initialize MCA in cpu_startup() so that it's ready before we wake-up
the application processors. This allows us to collect unconsumed AP
specific error records as part of the wake-up.
Machine Check Architecture (MCA) support code. Error records are
collected at boot and made available through sysctl(8). At the
moment, the following MIB names are created:
hw.mca.count - The number of error records collected.
hw.mca.first - The lowest sequence number present.
hw.mca.last - The highest sequence number present.
hw.mca.<X> - The error record with sequence number <X>.
Using sysctl(8) allows us to easily detect and analyze the records,
which is very helpful during development of MCA but can also be used
in production as a way to collect machine health statistics.
Modify our 'patch' utility to recognize the
\ No newline at end of file
line that some versions of diff print out if the last line of the two files
are different, and one of the two files does not have a newline character
on that last line.
This change is still somewhat under discussion in -arch and -standards, but I
want to commit it to -current today so I'd have the chance to MFC it to -stable
before the code freeze for 4.6-release (which would be May 1st).
Note: the related change to 'diff' (so it might *generate* that line) is NOT
expected to be included in 4.6-release. We can debate that change later.

Do not install games and profiled libraries to the ${CHROOTDIR}
with the initial installworld.
Eliminate the need in the second installworld. For that, make sure
_everything_ is built in the "world" environment, using the right
tool chain.
Added SUBDIR_OVERRIDE helper stuff to Makefile.inc1. Split the
buildworld process into stages, and skip some stages when
SUBDIR_OVERRIDE is set (used to build crypto, krb4, and krb5
dists).
Added NO_MAKEDB_RUN knob to Makefile.inc1 to avoid running
makewhatis(1) at the end of installworld (used when making crypto,
krb4, and krb5 dists).
In release/scripts/doFS.sh, ensure that the correct boot blocks are
used.
Moved the creation of the "crypto" dist from release.5 to
release.2.
In release.3 and doMFSKERN, build kernels in the "world"
environment. KERNELS now means "additional" kernels, GENERIC is
always built.
Ensure we build crunched binaries in the "world" environment.
Obfuscate release/Makefile some more (WMAKEENV) to achieve this.
Inline createBOOTMFS target.
Use already built GENERIC kernel modules to augment mfsfd's
/stand/modules. GC doMODULES as such.
Assorted fixes:
Get rid of the "afterdistribute" target by moving the single use
of it from sys/Makefile to etc/Makefile's "distribute".
Makefile.inc1: apparently "etc" no longer needs to be last for
"distribute" to succeed.
gnu/usr.bin/perl/library/Makefile.inc: do not override the
"install" and "distribute" targets, do it the "canonical" way.
release/scripts/{man,cat}pages-make.sh: make sure Perl manpages and
catpages appear in the right dists. Note that because Perl does
not respect the MANBUILDCAT (and NOMAN), this results in a loss of
/usr/share/perl/man/cat* empty directories. This will be fixed
soon.
Turn MAKE_KERBEROS4 into a plain boolean variable (if it is set it
means "make KerberosIV"), as documented in the make.conf(5)
manpage. Most of the userland makefiles did not test it for "YES"
anyway.
XXX Should specialized kerberized libpam versions be included into
the krb4 and krb5 dists? (libpam.a would be incorrect anyway if
both krb4 and krb5 dists were choosen.)
Make sure "games" dist is made before "catpages", otherwise games
catpages settle in the wrong dist.
