If you are running Linux 2.6, you only need to run `make` again. The Linux
build-script will detect the changes, because of a changed timestamp.

Normally the process is you run 'make' from the root of the kernel
source tree.

The exact process you use to process a working binary depends on the
architecture you're running.  On my main box here (Dual PIII 1GHz), I
use something like:

$ make -j8 bzImage modules

When cross-compilling a kernel for my SGI Indy, I use:
$ make -j8 vmlinux modules CROSS_COMPILE=mips-unknown-linux-gnu-

Similar for my Gateway Microserver (rebadged Cobalt Qube 2):
$ make -j8 vmlinux modules CROSS_COMPILE=mipsel-unknown-linux-gnu-

To the others: What's happening with the Kernel HOWTO?  That guide
covered a lot about how to do this...?

Also, remember that you can use the -C argument to make, to tell it to
change directories first... e.g. 'make -C /path/to/kernel/source' will
do what you want without having to manually 'cd' first.
