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.

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].

a "locked" version that will only handle a single network stack
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

- (cleanup) remove rmi specific 'struct mips_intrhand' - this is no
longer needed since 'struct intr_event' have all the required hooks
- add xlr_cpu_establish_hardintr, which has args for pre/post ithread
and filter hooks, so that the PCI code can add the PCI controller
interrupt ack code here
- make 'cpu_establish_hardintr' use the above function.
- (fix) change type of eirr/eimr from register_t to uint64_t. These
have to be 64bit otherwise we cannot handle interrupts from 32.
- (fix) use eimr to mask eirr before checking interrupts, so that we
will not handle masked interrupts.

UMA segments at their physical addresses instead of into KVA. This emulates
the direct mapping behavior of OEA32 in an ad-hoc way. To make this work
properly required sharing the entire kernel PMAP with Open Firmware, so
ofw_pmap is transformed into a stub on 64-bit CPUs.
Also implement some more tweaks to get more mileage out of our limited
amount of KVA, principally by extending KVA into segment 16 until the
beginning of the first OFW mapping.

of its argument before atomically replacing it, which could occasionally
return the wrong value on an SMP system. This resulted in user mutex
operations hanging when using threaded applications.
This header file uses __packed, without including <sys/cdefs.h>. This
means it cannot be used in the way described in sysarch(3) by only
including <machine/sysarch.h>.
The backtrace code tries to look for an instruction of the form "sw ra, x(sp)"
to figure out the program counter of the calling function. When we generate
the kernel exception frame we store the 'ra' at the time of the exception
using an instruction of the same form. The problem is that the 'ra' at the
time of the exception is not the same as the 'program counter' at the time
of the exception.
The fix is to save the 'exception program counter' register by staging
it through the 'ra' register.
