74cf8088e7 Prefer exit(0) from main over return(0).
Although not explicitly mentioned in style(9), it allows for easier
grepping of exit points. This reverts part of r203926.

16e435ca61 Changing proto_socketpair.c compilation and linking order revealed

6c820f6479 Decompose the most lousy named file in sys/kern; kern_subr.c.
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.

e1faba5621 ifconfig(8) expects interface fooX to be supported by the module if_foo,
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.

1fdea921e1 Add proper const keywords to sysctl(3) parameters.
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.

002bfbf796 Some machines can not only consist of CPUs running at different speeds
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.

f7a42cd9ea Increase PCIe maximuim read request size to 2048. Because re(4) uses
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.

27d5a92985 Start to implement ifnet DDB support:
- '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].

c3a2e02803 Some fixes to the current RMI interrupt handling, changes in this patch are:
- (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.

4eb3d8da4b Reduce KVA pressure on OEA64 systems running in bridge mode by mapping
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.
