aa4d7a8a4b Use three UMA zones for FFS/UFS inodes instead of malloc space.
Since inodes are currently 144 bytes, this will save 112 bytes per
inode.  This can amount to up to 10MByte on large systems.

a106c6930a - Change the way the direct mapped region is implemented to be generally
useful for accessing more than 1 page of contiguous physical memory, and
  to use 4mb tlb entries instead of 8k.  This requires that the system only
  use the direct mapped addresses when they have the same virtual colour as
  all other mappings of the same page, instead of being able to choose the
  colour and cachability of the mapping.
- Adapt the physical page copying and zeroing functions to account for not
  being able to choose the colour or cachability of the direct mapped
  address.  This adds a lot more cases to handle.  Basically when a page has
  a different colour than its direct mapped address we have a choice between
  bypassing the data cache and using physical addresses directly, which
  requires a cache flush, or mapping it at the right colour, which requires
  a tlb flush.  For now we choose to map the page and do the tlb flush.

This will allows the direct mapped addresses to be used for more things
that don't require normal pmap handling, including mapping the vm_page
structures, the message buffer, temporary mappings for crash dumps, and will
provide greater benefit for implementing uma_small_alloc, due to the much
greater tlb coverage.

36fea5de60 rn_walktree*() compute the next leaf before applying a function
to current leaves because function may vanish the current node.

If parent RTA_GENMASK route has a clone (a "cloning clone"), an
rn_walktree_from() starting from parent will cause another walk
starting from clone.  If a function is either rt_fixdelete() or
rt_fixchange(), this recursive walk may vanish the leaf that is
remembered by an outer walk (the "next leaf" above), panicing a
system when it resumes with an outer walk.

The following script paniced my single-user mode booted system:

: sysctl net.inet.ip.forwarding=1
: ipfw add 1 allow ip from any to any
: ifconfig lo0 127.1
: route add -net 10 -genmask 255.255.255.0 127.1
: telnet 10.1			# rt_fixchange() panic
: telnet 10.2
: telnet 10.1
: route delete -net 10		# rt_fixdelete() panic

For the time being, avoid these races by disallowing recursive
walks in rt_fixchange() and rt_fixdelete().

Also, make a slight optimization in the rtrequest(RTM_RESOLVE)
case: there is no reason to call rt_fixchange() in this case.

b8eb0267c0 - Add a pmap pointer to struct md_page, and use this to find the pmap that
a mapping belongs to by setting it in the vm_page_t structure that backs
  the tsb page that the tte for a mapping is in.  This allows the pmap that
  a mapping belongs to to be found without keeping a pointer to it in the
  tte itself.
- Remove the pmap pointer from struct tte and use the space to make the
  tte pv lists doubly linked (TAILQs), like on other architectures.  This
  makes entering or removing a mapping O(1) instead of O(n) where n is the
  number of pmaps a page is mapped by (including kernel_pmap).
- Use atomic ops for setting and clearing bits in the ttes, now that they
  return the old value and can be easily used for this purpose.
- Use __builtin_memset for zeroing ttes instead of bzero, so that gcc will
  inline it (4 inline stores using %g0 instead of a function call).
- Initially set the virtual colour for all the vm_page_ts to be equal to their
  physical colour.  This will be more useful once uma_small_alloc is
  implemented, but basically pages with virtual colour equal to phsyical
  colour are easier to handle at the pmap level because they can be safely
  accessed through cachable direct virtual to physical mappings with that
  colour, without fear of causing illegal dcache aliases.

In total these changes give a minor performance improvement, about 1%
reduction in system time during buildworld.

551d79e177 Fix multiple registration of the elf_legacy_coredump sysctl variable.
The duplication is caused by the fact that imgact_elf.c is included
by both imgact_elf32.c and imgact_elf64.c and both are compiled by
default on ia64. Consequently, we have two seperate copies of the
elf_legacy_coredump variable due to them being declared static, and
two entries for the same sysctl in the linker set, both referencing
the unique copy of the elf_legacy_coredump variable. Since the second
sysctl cannot be registered, one of the elf_legacy_coredump variables
can not be tuned (if ordering still holds, it's the ELF64 related one).

The only solution is to create two different sysctl variables, just
like the elf<32|64>_trace sysctl variables. This unfortunately is an
(user) interface change, but unavoidable. Thus, on ELF32 platforms
the sysctl variable is called elf32_legacy_coredump and on ELF64
platforms it is called elf64_legacy_coredump. Platforms that have
both ELF formats have both sysctl variables.

These variables should probably be retired sooner rather than later.

cc7bab9032 Modify the fake cylinders calculation so it is >= the size of the device,

Fix a serious bug in the handling of the RS_NO_CLEAR_UA quirk.  When we
go and insert the test-unit-ready command the umass_cam_quirk_cb() function
sets the status as if the READ_CAPACITY command suceeded when, in fact, it
did not.  This leads to the CAM layer trying to use garbage in the return
buffer and panicing the system (or doing other bad things).

Add a quirk entry for MSYSTEMS DISK-ON-KEY, which is sold under the Sony
brand as a solid state disk-on-key usb device.  This device requires
several quirks to work properly.

Note that the disk-on-key device will not work properly until CAM also
gets a quirk entry for it, which has been submitted to the CAM maintainer,
and you may have to temporarily uncomment the DELAY() as well.  -current
does not properly wait for devices to power up so you may also have
to temporarily uncomment the DELAY(300000) to make your device work.

698df1f738 Fix two bugs in the DMA chaining code for OHCI. The first bug is that
the dataphysend calculation could only possibly work if the virtual buffer
is also physically contiguous.  Calculate dataphysend by calculating the
ending virtual address first, then converting to a physical address.

The second bug applies only to NetBSD and OpenBSD and involves the curlen
calculation in the two-contiguous-physical-pages case (which we don't support).

Also cleanup the use of the OHIC_PAGE() macro on dataphysend and add a panic
if len goes negative (meaning we lost the physical page translation
representing the end of the buffer).

IMHO the dataphysend is still bokered since it might be misrepresented
by shared userland page mappings.  The whole section needs to be rewritten
to use the virtual address range.

fe6fb873dc Under some circumstances, the loopback interface will allocate a new
mbuf for a packet looping back to provide alignment guarantees for
KAME.  Unfortunately, this code performs a direct copy of the header
rather than using a header copying primitive (largely because we have
sucky header copying primitives).  This results in a multiple free
of the MAC label in the header when the same label data is freed
twice when the two mbufs with that header are freed.  As a temporary
work-around, clear the initialized flag on the label to prevent the
duplicate free, which prevents panics on large unaligned loopback
IP and IPv6 data.  The real fix is to improve and make use of proper
packet header copying routines here.

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.

fa7dd9c5bc Change the way ELF coredumps are handled. Instead of unconditionally
skipping read-only pages, which can result in valuable non-text-related
data not getting dumped, the ELF loader and the dynamic loader now mark
read-only text pages NOCORE and the coredump code only checks (primarily) for
complete inaccessibility of the page or NOCORE being set.

Certain applications which map large amounts of read-only data will
produce much larger cores.  A new sysctl has been added,
debug.elf_legacy_coredump, which will revert to the old behavior.

This commit represents collaborative work by all parties involved.
The PR contains a program demonstrating the problem.

389d2b6e21 Fix a refcount race with the vmspace structure. In order to prevent
resource starvation we clean-up as much of the vmspace structure as we
can when the last process using it exits.  The rest of the structure
is cleaned up when it is reaped.  But since exit1() decrements the ref
count it is possible for a double-free to occur if someone else, such as
the process swapout code, references and then dereferences the structure.
Additionally, the final cleanup of the structure should not occur until
the last process referencing it is reaped.

This commit solves the problem by introducing a secondary reference count,
calling 'vm_exitingcnt'.  The normal reference count is decremented on exit
and vm_exitingcnt is incremented.  vm_exitingcnt is decremented when the
process is reaped.  When both vm_exitingcnt and vm_refcnt are 0, the
structure is freed for real.

which is not legal in TCP.

0db138a6b0 Only the most recent snapshot contains the complete list of blocks
that were copied in all of the earlier snapshots, thus its precomputed
list must be used in the copyonwrite test. Using incomplete lists may
lead to deadlock. Also do not include the blocks used for the indirect
pointers in the indirect pointers as this may lead to inconsistent
snapshots.

0f5f789c0d The buffer daemon cannot skip over buffers owned by locked inodes as
they may be the only viable ones to flush. Thus it will now wait for
an inode lock if the other alternatives will result in rollbacks (and
immediate redirtying of the buffer). If only buffers with rollbacks
are available, one will be flushed, but then the buffer daemon will
wait briefly before proceeding. Failing to wait briefly effectively
deadlocks a uniprocessor since every other process writing to that
filesystem will wait for the buffer daemon to clean up which takes
close enough to forever to feel like a deadlock.

578dcf0c31 Keep trying to flush the vnode list for the mount while some are still
busy and we are making progress towards making them not busy. This is
needed because smbfs vnodes reference their parent directory but may
appear after their parent in the mount's vnode list; one pass over the
list is not sufficient in this case.

This stops attempts to unmount idle smbfs mounts failing with EBUSY.
