patching 3.9

[Michael Endsley]

I am preparing to do patch 002 for 3.9, but have a question before
starting. 
The file states:
"Apply by doing:
        cd /usr/src/XF4
        patch -p0 < 002_xorg.patch

And then rebuild and install X:
        make build"

After applying the patch, do I "make build" and then "make install" or
do I:
make build
make
make install? 

OR, as the file states, just do a "make build" and reboot? I don't
understand.
I have only done one patch before (001) and it was explicit on what to
do. 
Thanks.
Mike
