Since 6be63bbbda (lmo) rsp.
af3a1f6f48 (kernel.org) the Malta code does
no longer probe for presence of GCMP if CMP is not configured. This means
that the variable gcmp_present well be left at its default value of -1
which normally is meant to indicate that GCMP has not yet been mmapped.
This non-zero value is now interpreted as GCMP being present resulting
in a write attempt to a GCMP register resulting in a crash.
Reported and a build fix on top of my fix by Rob Landley <rob@landley.net>.

This is to move the gcmp_probe call to before the use of and selection of
the smp_ops functions. This allows malta with 1004K to work.

The variable `mips_revision_corid' is needlessly defined global in
arch/mips/mti-malta/malta-init.c, and this patch makes it static.
Build-tested with malta_defconfig.

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.
