LASAT's sysctl interface was broken, it failed a check during boot because
a single entry had a sysctl number and the rest were unnumbered. When I
fixed it I noticed that the whole sysctl file needed a spring clean, it was
using mutexes where it wasn't needed (it's only needed to protect during
writes to the EEPROM), so I moved that stuff out and generally cleaned the
whole thing up.

So now, LASAT's sysctl/proc interface is working again.

Assuming the call of kmap_coherent in local_r4k_flush_cache_page doesn't

After the common MIPS CPU interrupt controller (for irq0-7) was introduced
the Lasat boards didn't get their interrupts right, so nothing worked. The
old routines need to be offset by the new 8 hardware interrupts common to
all MIPS CPU's.

 The SWARM defconfig file has not been regenerated for over a year now.
Here is a patch to bring the file up to date.  Additionally some important
and sometimes confusing changes happened meanwhile.  Here is the list of
notable corresponding updates to the configuration:

1. CPU_SB1_PASS_2_2 is now selected rather than CPU_SB1_PASS_1.  The
   latter requires a non-standard -msb1-pass1-workarounds option to be
   supported by GCC and I am told is quite rare anyway.

   [Ralf: Afaik -msb1-pass1-workarounds is available only in Monta Vista's
   special Sibyte gcc 3.0 variant and gcc 3.0 is too old to build a modern
   kernel anyway.]

2. PHYLIB and BROADCOM_PHY are both built in and NETDEV_1000 enabled as
   required by SB1250_MAC.

3. USB and USB_OHCI_HCD are enabled as there is an OHCI chip onboard.

4. TMPFS is enabled, because I use it. ;-)

We can't probe all legacy ISA IDE ports by default as the resources may be
occupied by other ISA devices.  Add "probe_mask" module parameter and probe
only first two ISA IDE ports by default leaving the decision about probing
the rest to the user (systems with ISA ide2-6 should be very, very rare).

This fixes a regression caused by:
