Attached File:
 The following files are included.
- lkcd_ipf.patch
    This patch includes changes of LKCD for IPF support.
- lkcdutils_dwarf2.patch
    patch of lkcdutils, including dwarf2 format support.

How To Use:
I) Make kernel
   1. Download linux-2.6.2 source tree
   2. Download the LKCD patch for linux-2.6.2 from cvs as follows.

cvs -z3 -d:pserver:ano...@cv...:/cvsroot/lkcd co -r
linux262 2.6

   3. Apply the existing lkcd patch for linux-2.6.2
   4. Apply lkcd_ipf.patch
   5. Make and install kernel.
   6. cp linux-2.6.2/init/kerntypes.o /boot/Kerntypes
   7. cp linux-2.6.2/System.map /boot/System.map

II) Make lkcdutils
   1. Download the lkcdutils source for linux-2.6.2 as follows.

cvs -z3 -d:pserver:ano...@cv...:/cvsroot/lkcd co -r
linux262 lkcdutils

   2. Apply lkcdutils_dwarf2.patch
   3. configure --swp_hdr_size=<value of page size>
        default value is 4096 if not specified.
      Note:
        --swp_hdr_size indecates the size of the swap header.
        Its value is same as the PAGESIZE used by kernel
   4. make and make install
