[PATCH] README - Explain new 2.6.xx.x bug-fix release numbering scheme

[Daniel Andersen]

This patch explains the new 2.6.xx.x bug-fix release numbering scheme 
introduced with 2.6.8.1. I hope this can help people understand how to 
patch such kernels.

+   As of kernel 2.6.8 there was a bug-fix release numbering scheme
+   introduced. In such cases a fourth number is added to the release
+   version, eg. 2.6.8.1. When patching from a 2.6.xx(.x) release to a
+   newer version, patches are to be applied against the original
+   release, eg. 2.6.8 and not the bug-fix release 2.6.8.1. Old patches
+   can be reversed by adding the "-R" option to patch.

     Alternatively, the script patch-kernel can be used to automate this
     process.  It determines the current kernel version and applies any
     patches found.

How about giving an example like:

    To apply a bugfix release patch:
    # cd /usr/src/linux-2.6.8
    # patch -p1 <../patch-2.6.8.1

    To apply a new release on a bugfix tree:
    # cd /usr/src/linux-2.6.8.1
    # patch -p1 -R <../patch-2.6.8.1
    # patch -p1 <../patch-2.6.9

Examples are always good.
