3a150bca9c Some kernel threads try to do significant work, and the default KSTACK_PAGES
doesn't give them enough stack to do much before blowing away the pcb.
This adds MI and MD code to allow the allocation of an alternate kstack
who's size can be speficied when calling kthread_create.  Passing the
value 0 prevents the alternate kstack from being created.  Note that the
ia64 MD code is missing for now, and PowerPC was only partially written
due to the pmap.c being incomplete there.
Though this patch does not modify anything to make use of the alternate
kstack, acpi and usb are good candidates.

7a693db242 Back our kernel support for reliable signal queues.
Requested by:	rwatson, phk, and many others

0341f71df1 First half of implementation of ksiginfo, signal queues, and such. This
gets signals operating based on a TailQ, and is good enough to run X11,
GNOME, and do job control.  There are some intricate parts which could be
more refined to match the sigset_t versions, but those require further
evaluation of directions in which our signal system can expand and contract
to fit our needs.

After this has been in the tree for a while, I will make in kernel API
changes, most notably to trapsignal(9) and sendsig(9), to use ksiginfo
more robustly, such that we can actually pass information with our
(queued) signals to the userland.  That will also result in using a
struct ksiginfo pointer, rather than a signal number, in a lot of
kern_sig.c, to refer to an individual pending signal queue member, but
right now there is no defined behaviour for such.

CODAFS is unfinished in this regard because the logic is unclear in
some places.

045035c203 The AAC_COMPAT_LINUX option was really annoying, since it made the
aac driver dependent on the linux emulation module.  This was
especially bad for the release engineers who tried to move the
aac driver from the kernel onto the drivers floppy.  The linux
compat bits for this driver are now in their own driver, aac_linux.
It can be loaded as a module or compiled into the kernel.  For
the latter case, the AAC_COMPAT_LINUX option is needed, along with
the COMPAT_LINUX option.

I've tested this in every configuration I can think of.  This is an
MFC candidate for 4.7.

3c64027d75 Add a new legacy(4) device driver for use on machines that do not have
ACPI or for when ACPI support is disabled or not present in the kernel.
Basically, the nexus device is now split into two with some parts
(such as adding default ISA, MCA, and EISA busses if they aren't found
as well as support for PCI bus device ivars) being moved to the legacy
driver.

be3bee9396 Moved nfs_diskless setup code from autoconf.c to nfsclient/nfs_diskless.c
so that it is MI.  Allow nfs_mountroot to return an error if the nfs_diskless
struct is not valid, rather than panicing later on.  Call nfs_setup_diskless()
from nfs_mountroot if NFS_ROOT is defined, like bootpc_init().  Removed legacy
root mount support for sparc64, and enabled NFS_ROOT by default.

a51c9b6627 Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

a054ba3c90 Move the KSTACK_PAGES option from MD to MI. Although not all platforms
support this, we do have MI code that references it and is otherwise
unaware of an override.  The alternative is to put knowledge in these
MI files about which platforms have the opt_kstack_pages.h option file.
It is more likely that other platforms will gain the ability to tune the
kstack size.

fa099d1548 Automatically enable CPU_ENABLE_SSE (detect and enable SSE instructions)
if compiling with I686_CPU as a target.  CPU_DISABLE_SSE will prevent
this from happening and will guarantee the code is not compiled in.

I am still not happy with this, but gcc is now generating code that uses
these instructions if you set CPUTYPE to p3/p4 or athlon-4/mp/xp or higher.

907be9c6f2 Bump the -mev56 to -mev6. Otherwise, when you compile with gcc using
ev6 or pca56 etc this downgrades the cpu specification passed to gas.
As a result, gas will fail when gcc generates media instructions (in
uipc_usrreq.c).  This only affects what gas will accept, not what gcc
generates or what our *.s file contain.
