devices. This is a nop, except for what's reported by atmelbus for the
resources.
It would be nice if we could dymanically allocated these things, but
the pmap_mapdev panics if we don't keep the static mappings, so we
still need to play the carefully allocate VA space between all
supported SoC game.
User's with their own devices may need to make adjustments.

Add an option WITHOUT_NCURSESW to suppress building and linking to
libncursesw. While wide character support it useful we'd like to
only need one ncurses library on embedded systems.

the virtio backends.
- Add a new ioctl to export the count of pins on the I/O APIC from vmm
to the hypervisor.
- Use pins on the I/O APIC >= 16 for PCI interrupts leaving 0-15 for
ISA interrupts.
- Populate the MP Table with I/O interrupt entries for any PCI INTx
interrupts.
- Create a _PRT table under the PCI root bridge in ACPI to route any
PCI INTx interrupts appropriately.
- Track which INTx interrupts are in use per-slot so that functions
that share a slot attempt to distribute their INTx interrupts across
the four available pins.
- Implicitly mask INTx interrupts if either MSI or MSI-X is enabled
and when the INTx DIS bit is set in a function's PCI command register.
Either assert or deassert the associated I/O APIC pin when the
state of one of those conditions changes.
- Add INTx support to the virtio backends.
- Always advertise the MSI capability in the virtio backends.

known in advance, or where the caller doesn't care and just keeps
reading until it hits EOF.
In fetch_read(): the socket is non-blocking, so read() will return 0
on EOF, and -1 (errno == EAGAIN) when the connection is still open but
there is no data waiting. In the first case, we should immediately
return 0. The EINTR case was also broken, although not in a way that
matters.
In fetch_writev(): use timersub() and timercmp() as in fetch_read().
In http_fillbuf(): set errno to a sensible value when an invalid chunk
header is encountered.
In http_readfn(): as in fetch_read(), a zero return from down the
stack indicates EOF, not an error. Furthermore, when io->error is
EINTR, clear it (but no errno) before returning so the caller can
retry after dealing with the interrupt.

swcr_newsession can change the pointer for swcr_sessions which races with
swcr_process which is looking up entries in this array.
Add a rwlock that protects changes to the array pointer so that
swcr_newsession and swcr_process no longer race.

versions from elftoolchain upstream (r2974). Convert ctfconvert to
use the APIs from the new libdwarf and make ctfconvert work with Clang
3.4.
__FreeBSD_version is bumped to 1100006.
A list of notable changes:
[libelf]
* The old libelf source code in lib/libelf has been removed.
Instead, the new libelf is built from contrib/elftoolchain/libelf.
* Manual pages are largely improved.
* Internal implementation was refactored and improved for better
correctness and portability.
* Fixed a few memory leaks.
* Extended with extension APIs `elf_open()` and `elf_openmemory()`.
These APIs are similar to `elf_begin()` and `elf_memory()`
respectively, except that they return an ELF descriptor of kind
`ELF_K_NONE` instead of an error if the object being opened could
not be parsed.
* Implement support for translating sections of type ELF_T_VDEF and
ELF_T_VNEED.
* Improve `elf_update()` to check that the executable header, the
program header table, section contents and the section header table
do not overlap, and to ensure that gaps between extents are
filled with the fill character specified by `elf_fill()`.
* Allow `Elf_Data` descriptors to have types and alignments differing
from their containing section.
* Remove functionality controlled by `LIBELF_TEST_HOOKS`.
* Support processing of BSD-flavor archives.
* Add knowledge of section types `SHT_GNU_ATTRIBUTES` and
`SHT_GNU_LIBLIST`.
* Use elftoolchain style symbol versioning.
* Shared library version is bumped.
[libdwarf]
* The old libdwarf source code in lib/libdwarf has been removed.
Instead, the new libdwarf is built from contrib/elftoolchain/libdwarf.
* Support full DWARF3 and partial DWARF4 parsing.
* Support DWARF2 generation.
* Support for DWARF line number, call frame, location expression,
macro info and address ranges, among other things.
* The APIs for the new libdwarf are mostly compatible with the widely
used LGPL libdwarf. Some of the incompatible APIs from the old
libdwarf are kept as its own extensions. All the APIs are documented.
* Use elftoolchain style symbol versioning.
* Shared library version is bumped.
[ctfconvert]
* Switch to the APIs from the new libdwarf.
* Improve die_mem_offset() so that DW_AT_data_member_location attributes
generated by Clang 3.4 can be handled properly.
* Make use of DW_AT_byte_size attribute of the member DIE to calculate
the bits occupied by the member's type, without actually resolving
the type. This way ctfconvert can deal with the case that Clang 3.4
sometimes emits DIE for struct/union member before emitting the DIE
for the type of that member.
