Once we issue more BIO_DELETE, this will improve lifetime, and
possibly write speed of Flash based devices which have usable flash
adaptation layers.
For now, about the only usage is the newfs(1) -E flag.

Use bus_{read|write_*() instead of bus_space_{read|write}_*() for

Due to compiler optimizations and inlining, this is for all practical

is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.

- Introduce a finit() which is used to initailize the fields of struct file
in such a way that the ops vector is only valid after the data, type,
and flags are valid.
- Protect f_flag and f_count with atomic operations.
- Remove the global list of all files and associated accounting.
- Rewrite the unp garbage collection such that it no longer requires
the global list of all files and instead uses a list of all unp sockets.
- Mark sockets in the accept queue so we don't incorrectly gc them.

possible to end up in the interrupt handler again while processing the
previous RX interrupt in ifp->if_input() because the MD interrupt code
disables the delivery of the respective interrupt until all associated
handlers were called (in the INTR_FILTER case the MI code supposedly
does the same). Toggling the NIC interrupt enable bit in these handlers
still is necessary though as some chips (f.e. the VMware emulated one)
require this to be done in order to keep issuing interrupts.

implemented with macros. This patch improves code readability. Reasoning
behind vidd_* is a sort of "video discipline".
List of macros is supposed to be complete--all methods of video_switch
ought to have their respective macros from now on.
Functionally, this code should be no-op. My intention is to leave current
behaviour of touched code as is.

- Use the correct offsets when copying out the results of PCIOCGETCONF_OLD.
This happened to not affect the 64-bit architectures because there the
addition of pc_domain to struct pcisel didn't change the overall size of
struct pci_conf. [1]
- Always copy the name and unit information to conf_old so it's also part
of the output once this information is cached in dinfo.
- Use the correct type for flags in struct pci_match_conf_old. This
change is more or less cosmetic though.

The snp_target == NULL implies the snp_tty == NULL. Remove the code

In snpclose(), do the snp_detach() before scheduling the snp device
destruction. Otherwise, after the return from snpclose(), the snp
device is already removed from the snp_list, but tty is still in
snooped state. Any attempt to do i/o on such tty cause panic because

a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.
The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.
With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.

it's multi DAC / playback channels is not that good. Enabling vchans
make the bug more visible since playback allocation will look for
possible free hardware channels first (i.e: the next DAC, the very first
has been consumed by vchan mixer) which in this case has been proven faulty.
