Currently we use two separate spinlocks to protect both the hash/mapping table
and the default entry.  This could be considered a bit foolish because it adds
complexity without offering any real performance advantage.  This patch
removes the dedicated default spinlock and protects the default entry with the
hash/mapping table spinlock.

The NetLabel/LSM domain hash table search function used an argument to specify
if the default entry should be returned if an exact match couldn't be found in
the hash table.  This is a bit against the kernel's style so make two separate
functions to represent the separate behaviors.

This patch removes some unneeded RCU read locks as we can treat the reads as
"safe" even without RCU.  It also converts the NetLabel configuration refcount
from a spinlock protected u32 into atomic_t to be more consistent with the rest
of the kernel.

Based upon the 2.4 kernel, the information presented in the
Documentation/mips/GT64120.README file is outdated. Worse,
the document contents are plain misleading nowadays because
the text mentions files and directories, which have been
deleted, moved or restructured for 2.6.

This patch removes the documentation, which is no more valid.

The Qemu platform was originally implemented to have an easily supportable

Since the latest release Qemu is capable of emulating the MIPSsim and
Malta platforms, so this goal has been reached.  The Qemu plaform is also
rather underfeatured so less useful than a Malta emulation.

A raw binary boots about twice as fast as SREC.

The possibility to generate SREC binaries remains by simply using the
vmlinux.srec target but seems only useful for the probably hypothetical
