Applying a patch

[Man-wai Chang]

I am trying to apply the patch-2.6.21.4 onto the 2.6.21.3 trunk, and got 
the following screen:

root at www:/usr/src# cd linux-2*
root at www:/usr/src/linux-2.6.21.3# bunzip2 -dck /usr/sr/tar/patch* | 
patch -p1
bunzip2: Can't open input file /usr/sr/tar/patch*: No such file or 
directory.
root at www:/usr/src/linux-2.6.21.3# bunzip2 -dck /usr/src/tar/patch* | 
patch -p1
patching file Makefile
Hunk #1 FAILED at 1.
1 out of 1 hunk FAILED -- saving rejects to file Makefile.rej
patching file arch/arm/kernel/traps.c
Reversed (or previously applied) patch detected!  Assume -R? [n]

What am I supposed to do?
