	Removed all traces of my old table () Linux kernel hack.

	* kernel: Removed.
	* sysdeps/kernel: Removed.
	* libgtop-sysdeps.m4: Don't check for table (); it does not
	exist any longer.

This is a new system call `table ()' for the Linux table. It is faster
than reading from /proc and can be used to fetch all information required
for libgtop until whe have some other function (extended sysctl, ...) in
standard kernels.
I didn't want to change sysctl or some other function myself cause this may
cause other applications relying upon those function to fail. This is
something for the ``real'' kernel gurus ...
To use this new system call for libgtop, do the following:
* Copy this directory to /usr/src/linux/table
* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
If you want to change and/or add something - feel free to do so !
Have fun,
Martin

The pentium has a MESI cache so the spin without lock will exit when
another CPU write invalidates our cache, and the lock is avoided when
possible so we don't play ping-pong games with the cache line.

This is a new system call `table ()' for the Linux table. It is faster
than reading from /proc and can be used to fetch all information required
for libgtop until whe have some other function (extended sysctl, ...) in
standard kernels.
I didn't want to change sysctl or some other function myself cause this may
cause other applications relying upon those function to fail. This is
something for the ``real'' kernel gurus ...
To use this new system call for libgtop, do the following:
* Copy this directory to /usr/src/linux/table
* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
If you want to change and/or add something - feel free to do so !
Have fun,
Martin
