Don't depend on CONFIG_IDE to make this more robust.

The Malta board aliases 0x80000000 - 0xffffffff to 0x00000000
- 0x7fffffff ignoring the 256 MB IO hole in 0x10000000.
The physical memory is shifted to 0x80000000 so up to 2GB
can be used. Kuseg is expanded to 3GB (due to board limitations
only 2GB can be accessed) and lowmem (kernel space) is expanded to 2GB.
The Segment Control registers are programmed as follows:
Virtual memory Physical memory Mapping
0x00000000 - 0x7fffffff 0x80000000 - 0xfffffffff MUSUK (kuseg)
0x80000000 - 0x9fffffff 0x00000000 - 0x1ffffffff MUSUK (kseg0)
0xa0000000 - 0xbf000000 0x00000000 - 0x1ffffffff MUSUK (kseg1)
0xc0000000 - 0xdfffffff - MK (kseg2)
0xe0000000 - 0xffffffff - MK (kseg3)
The location of exception vectors remain the same since 0xbfc00000
(traditional exception base) still maps to 0x1fc00000 physical.

Remove the Malta-specific CM probe code and instead make use of the
newly added generic CM code.

Some MIPS controllers have hardware I/O coherency. This patch
detects those and turns off software coherency. A new kernel
command line option also allows the user to manually turn
software coherency on or off.

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with
error: $variablename causes a section type conflict
because a section containing const variables is marked read only and so
cannot contain non-const variables.

This patch explicitly removes the kgdb implementation, for mips which
is intended to be followed by a patch that adds a kgdb implementation
for MIPS that makes use of the kgdb core in the kernel.
