v2.6.28-rc1~271^2^4~6

The CONFIG_PHYS_ADDR_T_64BIT  was added as of v2.6.28-rc1~271^2^4~6,
this is either u32 or u64 dependent on 64BIT || ARCH_PHYS_ADDR_T_64BIT.
The ARCH_PHYS_ADDR_T_64BIT allows architectures to override the
value even if the platform does not have CONFIG_64BIT. We simplify
this check by just checking for all known architecture variables and
also the CONFIG_64BIT -- but we skip adding this if the arch is
x86 or PPC which already had phys_addr_t.

compat: add compat kernel checker and downloader

This adds get-compat-kernels, a utility that is intended
to be Linux distribution agnostic that downloads and installs
all kernel headers for all supported kernel releases of compat.
You also have the option of specifying you want to also install
the actual kernel image (get-compat-kernels -i).

We start off by adding support for Ubuntu on x86_64 as that
is what a few of us maintaining compat and compat-wireless run.
Just for kernel headers (default run of get-compat-kernels),
you'll need currently 205 M of hard drive space.

Once done with running get-compat-kernels, you can then
start running ckmake to verify your compat kernel changes
won't bust compilation against any known supported kernel.

I'd like to start requiring runs against this script for
patch submissions. Eventually we can try to add the same
runs against compat-wireless so we can verify integrity
against compilation for different kernel versions.

Support for different Linux distributios is welcomed.

Debug log goes out to ckmake.log

compat: backport kfree_rcu()

This adds a nested function everywhere kfree_rcu() was called. This
function frees the memory and is given as a function to call_rcu().
The kfree_rcu define was made by Johannes Berg.
The rcu callback could happen every time also after the module was
unloaded and this will cause problems.
A rcu_barrier() was added into every module_exit so that this will not
be called after the module was unloaded.

The define overwriting module_exit is based on the original module_exit
which looks like this:
/* This is only required if you want to be unloadable. */
/#define module_exit(exitfn)                                    \
        static inline exitcall_t __exittest(void)               \
        { return exitfn; }                                      \
        void cleanup_module(void) __attribute__((alias(#exitfn)));

We replaced the call to the actual function exitfn() with a call to our
function which calls the original exitfn() and then rcu_barrier()

As a module will not be unloaded that ofter it should not have a big
performance impact when rcu_barrier() is called on every module exit,
also when no kfree_rcu() backport is used in that module.
