no superpage mappings are created within the clean submap, aligning the
start of the clean submap helps to prevent interference with kmem_alloc()'s
use of superpages.
such that a fancier thermal management algorithm can be run from user

sound like a wind tunnel or catch fire.
Although not explicitly mentioned in style(9), it allows for easier
grepping of exit points. This reverts part of r203926.

Although this file has historically been used as a dumping ground for
random functions, nowadays it only contains functions related to copying
bits {from,to} userspace and hash table utility functions.
Behold, subr_uio.c and subr_hash.c.
and will try to load it if it's not present. To better meet these
expectations, change the module name for the loopback interface from
'loop' to 'if_lo'. The loopback interface is always compiled into the
base kernel, so there are no resulting changes in kld files, etc.

The `name' and `newp' arguments can be marked const, because the buffers
they refer to are never changed. While there, perform some other
cleanups:
- Remove K&R from sysctl.c.
- Implement sysctlbyname() using sysctlnametomib() to prevent
duplication of an undocumented kernel interface.
- Fix some whitespace nits.
It seems the prototypes are now in sync with NetBSD as well.
du(1), cp(1) etc, to prevent the crossing of mountpoints whilst using the

but also of different types, f.e. Sun Fire V890 can be equipped with a
mix of UltraSPARC IV and IV+ CPUs, requiring different MMU initialization
and different workarounds for model specific errata. Therefore move the
CPU implementation number from a global variable to the per-CPU data.
Functions which are called before the latter is available are passed the
implementation number as a parameter now.
This file was missed in r204152.
Tx DMA burst size 2048, I beleive PCIe maximum read request size
also should match to the value of Tx DMA burst size. With this
change I can get more than 800Mbps for TCP bulk transfers.
Previously I was not able to get more than 700Mbps. If I enable TSO
it now shows 927Mbps.

explicitly clear TSO on VLAN. While I'm here remove duplicated

Driver changes and userland support will follow.

- 'show ifnets' prints a list of ifnet *s per virtual network stack,
- 'show ifnet <struct ifnet *>' prints fields matching the given ifp.
We do not yet print the complete set of fields and might want to
factor this out to an extra if_debug.c file in case this grows
a lot[1]. We may also want to grow 'show ifnet <if_xname>' support[1].

instance. The latter is called directly from ip_destroy().
Hook up an ip_destroy() function to release resources from the
legacy IP network layer upon virtual network stack teardown.

- add bus_space_rmi_pci.c for PCI bus space
- files.xlr update for changes in files
- pcibus.c merged into xlr_pci.c (they were small files with inter-dependencies)
- xlr_pci.c - lot of changes here with few fixes, formatting cleanup

- remove pci related code from bus_space_rmi.c, we will have another
file for PCI bus space functions which will do byte-swapping.
- remove local SWAP implementation
- added TODO stub for unimplemented functions
