driver attaches to each cpu device and creates a sysctl node in that
device's sysctl context (dev.cpu.N.temperature). When invoked, the
handler binds to the appropriate CPU to ensure a correct reading.

previously conditionally acquired Giant based on debug.mpsafenet. As that
has now been removed, they are no longer required. Removing them
significantly simplifies error-handling in the socket layer, eliminated
quite a bit of unwinding of locking in error cases.
While here clean up the now unneeded opt_net.h, which previously was used
for the NET_WITH_GIANT kernel option. Clean up some related gotos for
consistency.

Also rename the related functions in a similar way.
There are no functional changes.
For a packet coming in with IPsec tunnel mode, the default is
to only call into the firewall with the "outer" IP header and
payload.
With this option turned on, in addition to the "outer" parts,
the "inner" IP header and payload are passed to the
firewall too when going through ip_input() the second time.
The option was never only related to a gif(4) tunnel within
an IPsec tunnel and thus the name was very misleading.

- Copy a bit more than func_end to try to copy the whole load_kernel()

- Add custom .c wrappers for the firmware, rather than the standard
firmware(9) generated firmware objects to work around toolchain
problems on ia64 involving linking objects produced by
ld -b -binary into the kernel.
- Move from using Myricom's ".dat" firmware blobs to using Myricom's
zlib compressed ".h" firmware header files. This is done to
facilitate the custom wrappers, and saves a fair amount of wired
memory in the case where the firmware is built in, or preloaded.

NET_NEEDS_GIANT, which will shortly be removed. This is done in a
away that it may be easily reattached to the build before 7.1 if
appropriate locking is added. Specifics:
- Don't install netatm include files
- Disconnect netatm command line management tools
- Don't build libatm
- Don't include ATM parts in rescue or sysinstall
- Don't install sample configuration files and documents
- Don't build kernel support as a module or in NOTES
- Don't build netgraph wrapper nodes for netatm
This removes the last remaining consumer of NET_NEEDS_GIANT.

- CMT_PF states added (w/sysctl to turn the PF version on)
- sctp_input.c had a missing incr of cookie case when the
auth was bad. This meant a free was called without an
increment to refcnt, added increment like rest of code.
- There was a case, unlikely, when the scope of the destination
changed (this is a TSNH case). In that case, it would not free
the alloc'ed asoc (in sctp_input.c).
- When listed addresses found a colliding cookie/Init, then
the collided upon tcb was not unlocked in sctp_pcb.c
- Add error checking on arguments of sctp_sendx(3) to prevent it from
referencing a NULL pointer.
- Fix an error return of sctp_sendx(3), it was returing
ENOMEM not -1.
- Get assoc id was changed to use the sanctified socket api
method for getting a assoc id (PEER_ADDR_INFO instead of
PEER_ADDR_PARAMS).
- Fix it so a peeled off socket will get a proper error return
if it trys to send to a different address then it is connected to.
- Fix so that select_a_stream can avoid an endless loop that
could hang a caller.
- time_entered (state set time) was not being set in all cases

ELF files. On ia64 the ELF header contains information about
characteristics of the machine code and ld(1) needs that to
determine whether input files are compatible for linking. To
this end non-ELF files are not supported by binutils on ia64.
However, the resulting ELF file seems to be correct despite the
warnings and the non-supportedness of non-ELF files and it
appears enough to unbreak the build of firmware(9) files on ia64
by simply supressing the warning.

- Adjust lock_profiling stubs semantic in the hard functions in order to be
more accurate and trustable
- Disable shared paths for lock_profiling. Actually, lock_profiling has a
subtle race which makes results caming from shared paths not completely
trustable. A macro stub (LOCK_PROFILING_SHARED) can be actually used for
re-enabling this paths, but is currently intended for developing use only.
- Use homogeneous names for automatic variables in hard functions regarding

allowing the driver for the host-PCI-bridge to indicate that
reenumeration of the PCI busses isn't supported by returning
-1 instead of a valid PCI bus number. This is needed in order
support both Tomatillo, which don't support reenumeration and
thus are apparently intended to be used for independently
numbered PCI domains only, and Psycho bridges, whose busses
need to be reenumerated on at least some E450, without the
#ifndef currently used for sun4v in order to support multiple
independently PCI domains. The actual allocation/incrementation
of the PCI bus numbers is now done in psycho(4), though it
no longer establish a mapping between bus numbers and device
nodes like ofw_pci_alloc_busno() did as that functionality
wasn't used (but can easily brought back if really needed).
The now no longer used sys/sparc64/pci/ofw_pci.c is also
removed from sys/conf/files.sun4v as ofw_pci_alloc_busno()
wasn't used there in the first place.

- Make psycho_softcs static to sys/sparc64/pci/psycho.c as

This allocator uses a binary buddy system with a twist. First and
foremost, this allocator is required to support the implementation of
superpages. As a side effect, it enables a more robust implementation
of contigmalloc(9). Moreover, this reimplementation of
contigmalloc(9) eliminates the acquisition of Giant by
contigmalloc(..., M_NOWAIT, ...).
The twist is that this allocator tries to reduce the number of TLB
misses incurred by accesses through a direct map to small, UMA-managed
objects and page table pages. Roughly speaking, the physical pages
that are allocated for such purposes are clustered together in the
physical address space. The performance benefits vary. In the most
extreme case, a uniprocessor kernel running on an Opteron, I measured
an 18% reduction in system time during a buildworld.
This allocator does not implement page coloring. The reason is that
superpages have much the same effect. The contiguous physical memory
allocation necessary for a superpage is inherently colored.
Finally, the one caveat is that this allocator does not effectively
support prezeroed pages. I hope this is temporary. On i386, this is
a slight pessimization. However, on amd64, the beneficial effects of
the direct-map optimization outweigh the ill effects. I speculate
that this is true in general of machines with a direct map.
