memory.txt: remove stray information 



Andi removed some outedated documentation from Documentation/memory.txt
back in 2009 by commit 3b2b9a87 ("Documentation/memory.txt: remove
some very outdated recommendations"), but the resulting document is not
in a nice shape either.

It seems to me like we are not losing anything by completely removing the
file now.

There are several classic problems related to memory on Linux

systems.



	1) There are some motherboards that will not cache above

	   a certain quantity of memory.  If you have one of these

	   motherboards, your system will be SLOWER, not faster

	   as you add more memory.  Consider exchanging your 

           motherboard.



All of these problems can be addressed with the "mem=XXXM" boot option

(where XXX is the size of RAM to use in megabytes).  

It can also tell Linux to use less memory than is actually installed.

If you use "mem=" on a machine with PCI, consider using "memmap=" to avoid

physical address space collisions.



See the documentation of your boot loader (LILO, grub, loadlin, etc.) about

how to pass options to the kernel.



There are other memory problems which Linux cannot deal with.  Random

corruption of memory is usually a sign of serious hardware trouble.

Try:



	* Reducing memory settings in the BIOS to the most conservative 

          timings.



	* Adding a cooling fan.



	* Not overclocking your CPU.



	* Having the memory tested in a memory tester or exchanged

	  with the vendor. Consider testing it with memtest86 yourself.

	

	* Exchanging your CPU, cache, or motherboard for one that works.
