7295465e33 Rewrite thread CPU usage percentage math to not depend on periodic calls
with HZ rate through the sched_tick() calls from hardclock().

Potentially it can be used to improve precision, but now it is just minus
one more reason to call hardclock() for every HZ tick on every active CPU.
SCHED_4BSD never used sched_tick(), but keep it in place for now, as at
least SCHED_FBFS existing in patches out of the tree depends on it.

8a5350984f Fix link status handling on if_arge upon system boot to allow bootp/NFS to
function.

From the submitter:

This patch fixes an issue I encountered using an NFS root with an
ar71xx-based MikroTik RouterBoard 450G on -current where the kernel fails
to contact a DHCP/BOOTP server via if_arge when it otherwise should be able
to.  This may be the same issue that Monthadar Al Jaberi reported against
an RSPRO on 6 March, as the signature is the same:

%%%

DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
.
.
.
DHCP/BOOTP timeout for server 255.255.255.255
DHCP/BOOTP timeout for server 255.255.255.255
arge0: initialization failed: no memory for rx buffers
DHCP/BOOTP timeout for server 255.255.255.255
arge0: initialization failed: no memory for rx buffers

%%%

The primary issue that I found is that the DHCP/BOOTP message that
bootpc_call() is sending never makes it onto the wire, which I believe is
due to the following:

- Last December, a change was made to the ifioctl that bootpc_call() uses
to adjust the netmask around the sosend().

- The new ioctl (SIOCAIFADDR) performs an if_init when invoked, whereas the
old one (SIOCSIFNETMASK) did not.

- if_arge maintains its own sense of link state in sc->arge_link_status.

- On a single-phy interface, sc->arge_link_status is initialized to 0 in
arge_init_locked().

- sc->arge_link_status remains 0 until a phy state change notification
causes arge_link_task to run, notice the link is up, and set it to 1.

- The inits caused by the ifioctls in bootpc_call are reinitializing the
interface, but not the phy, so sc->arge_link_status goes to 0 and remains
there.

- arge_start_locked() always sees sc->arge_link_status == 0 and returns
without queuing anything.

The attached patch changes arge_init_locked() such that in the single-phy
case, instead of initializing sc->arge_link_status to 0, it runs
arge_link_task() to set it according to the current phy state.  This change
has allowed my setup to mount an NFS root successfully.

eeaef4bae5 Correctly (I hope) deallocate the if_arge RX buffer ring on arge_stop().
I had some interesting hangs until I realised I should try flushing the
DDR FIFO register and lo and behold, hangs stopped occuring.

I've put in a few DDR flushes here and there in case people decide to
reuse some of these functions.  It's very very likely they're almost
all superflous.

To test:

* Connect to a network with a _lot_ of broadcast traffic
* Do this:
  # while true; do ifconfig arge0 down; ifconfig arge0 up; done

This fixes the mbuf exhaustion that has been reported when the interface
state flaps up/down.

Make our handling of MMX x SSE closer to what gcc does:

  * Enabling sse enables mmx.
  * Disabling (-mno-mmx) mmx, doesn't disable sse (we got this right already).
  * The order in not important. -msse -mno-mmx is the same as -mno-mmx -msse.

f8bee51a69 - Add ipfw eXtended tables permitting radix to be used for any kind of keys.
- Add support for IPv6 and interface extended tables
- Make number of tables to be loader tunable in range 0..65534.
- Use IP_FW3 opcode for all new extended table cmds

No ABI changes are introduced. Old userland will see valid tables for
IPv4 tables and no entries otherwise. Flush works for any table.

IP_FW3 socket option is used to encapsulate all new opcodes:
 /* IP_FW3 header/opcodes */
 typedef struct _ip_fw3_opheader {
        uint16_t opcode;        /* Operation opcode */
        uint16_t reserved[3];   /* Align to 64-bit boundary */
 } ip_fw3_opheader;

New opcodes added:
 IP_FW_TABLE_XADD, IP_FW_TABLE_XDEL, IP_FW_TABLE_XGETSIZE, IP_FW_TABLE_XLIST

ipfw(8) table argument parsing behavior is changed:
 'ipfw table 999 add host' now assumes 'host' to be interface name instead of
 hostname.

New tunable:
 net.inet.ip.fw.tables_max controls number of table supported by ipfw in given
 VNET instance. 128 is still the default value.

New syntax:
ipfw add skipto tablearg ip from any to any via table(42) in
ipfw add skipto tablearg ip from any to any via table(4242) out

This is a bit hackish, special interface name '\1' is used to signal interface
table number is passed in p.glob field.
