dd84a43c1d First commit of the GEOM subsystem to make it easier for people to
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.

fe86c44885 Add new support for locking an ATA channel and use that throughout
the ATA/ATAPI driver. This solves the concurrency problem with
the new GEOM code, and also cuts a good deal of the patch size

23bd68a426 Fix a bug in ufsdirhash_adjfree() that caused it to incorrectly
update the free-space statistics in some cases. The problem affected
directory blocks when the free space dropped below the size of the
maximum allowed entry size. When this happened, the free-space
summary information could claim that there are no further blocks
that can fit a maximum-size entry, even if there are.

The effect of this bug is that the directory may be enlarged even
though there is space within the directory for the new entry. This
wastes disk space and has a negative impact on performance.

Fix it by correctly computing the dh_firstfree array index, adding
a helper macro for clarity. Put an extra sanity check into
ufsdirhash_checkblock() to detect the situation in future.

3dbceccb78 As a XXX bandaid open the mounted device READ/WRITE even if we only mount
read-only.

The trouble here is that we don't reopen the device in read/write mode
when we remount in read/write mode resulting in a filesystem sending
write requests to a device which was only opened read/only.

I'm not quite sure how such a reopen would best be done and defer
the problem to more agile hackers.

60cf2c1254 Export a (machine dependent) kernel variable bootdev as
machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).

NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much.  The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".

Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

7c1e1cf188 Fix one genuine bug and a potential one:
-#if defined(__FreeBSD__) && __FreeBSD_version__ >= 500023
  +#if defined(__FreeBSD__) && __FreeBSD_version >= 500023

is a genuine bug -- __FreeBSD_version__ does not exist.
The other one:

  -#if (__FreeBSD__ < 5)
  +#if (__FreeBSD_version < 500000)

pops out when you cross-compile the code:

  __FreeBSD__			is a compiler predefine,
  __FreeBSD_version		is defined in <sys/param.h> .

Given that in this case (and all others in sys/dev/usb and sys/i4b)
the goal is to adapt to a different kernel interface, and not to
a compiler feature, I believe the correct form is the second one
(in the best case the two are synonyms so the change does not break
anything anyways).

ff91d7800f Revert change in revision 1.53 and add a small comment to protect
the revived code.

vm pages newly allocated are marked busy (PG_BUSY), thus calling
vm_page_delete before the pages has been freed or unbusied will
cause a deadlock since vm_page_object_page_remove will wait for the
busy flag to be cleared.  This can be triggered by calling malloc
with size > PAGE_SIZE and the M_NOWAIT flag on systems low on
physical free memory.

A kernel module that reproduces the problem, written by Logan Gabriel
<logan@mail.2cactus.com>, can be found in the freebsd-hackers mail
archive (12 Apr 2001).  The problem was recently noticed again by
Archie Cobbs <archie@dellroad.org>.

4f91e3efb2 Implement delivery of tlb shootdown ipis. This is currently more fine grained
than the other implementations; we have complete control over the tlb, so we
only demap specific pages.  We take advantage of the ranged tlb flush api
to send one ipi for a range of pages, and due to the pm_active optimization
we rarely send ipis for demaps from user pmaps.

Remove now unused routines to load the tlb; this is only done once outside
of the tlb fault handlers.
Minor cleanups to the smp startup code.

This boots multi user with both cpus active on a dual ultra 60 and on a
dual ultra 2.

39028e8396 Modify the tlb demap API to take a pmap instead of a tlb context number.
Due to allocating tlb contexts on the fly, we only ever need to demap the
primary context, non-primary contexts have already been implicitly flushed
by context switching.  All we really need to tell is if its a kernel demap
or not, and its easier just to compare against the kernel_pmap which is a
constant.

bc9b764621 Implement kthread context stealing. This is a bit of a misnomer because
the context is not actually stolen, as it would be for i386.  Instead of
deactivating a user vmspace immediately when switching out, and recycling
its tlb context, wait until the next context switch to a different user
vmspace.  In this way we can switch from a user process to any number of
kernel threads and back to the same user process again, without losing any
of its mappings in the tlb that would not already be knocked by the automatic
replacement algorithm.  This is not expected to have a measurable performance
improvement on the machines we currently run on, but it sounds cool and makes
the sparc64 port SMPng buzz word compliant.

d4621eac57 Fixed a printf format error again. Rev.127 was clobbered in rev.1.128
by removing parentheses.  The main bug is in gcc: on machines with
64-bit longs and 64-bit long longs,

    (unsigned long long)rdp->total_sectors / ((1024L * 1024L) / DEV_BSIZE))

has type plain unsigned long instead of the correctly promoted type
unsigned long long, so it can not be printfed using %llu format.  Even
1ULL / 1L is mispromoted.  Anyway, casting the correct operand
automatically avoids the problem.  We do not want to to pessimize the
division; we just want to convert to a common maximal type for printing.

b9b7a4be90 Add a sequential iteration optimization to vm_object_page_clean(). This
moderately improves msync's and VM object flushing for objects containing
randomly dirtied pages (fsync(), msync(), filesystem update daemon),
and improves cpu use for small-ranged sequential msync()s in the face of
very large mmap()ings from O(N) to O(1) as might be performed by a database.

A sysctl, vm.msync_flush_flag, has been added and defaults to 3 (the two
committed optimizations are turned on by default).  0 will turn off both
optimizations.

This code has already been tested under stable and is one in a series of
memq / vp->v_dirtyblkhd / fsync optimizations to remove O(N^2) restart
conditions that will be coming down the pipe.

fdc6e087c0 Reserve a mount flag, MNT_MULTILABEL, used by the MAC subsystem and
individual filesystems to determine whether they should operate in
"file system as a single object" mode, or "file system as a set of objects
with individual labels" mode.  Note: in the trustedbsd_mac branch,
this is refered to as "MNT_MULTILEVEL", but the two mean the same thing.
MNT_MULTILABEL is more suggestive of a flexible policy system than one
providing purely hierarchal policies.  The need for a reserved flag will
go away once nmount() is done.

88c99cfbc8 Add a new variable mp_maxid. This is used so that per cpu datastructures may
be allocated as arrays indexed by the cpu id.  Previously the only reliable
way to know the max cpu id was through MAXCPU. mp_ncpus isn't useful here
because cpu ids may be sparsely mapped, although x86 and alpha do not do this.

Also, call cpu_mp_probe much earlier so the max cpu id is known before the VM
starts up.  This is intended to help support per cpu queues for the new
allocator, but may be useful elsewhere.
