For x86 architectures, verify the 64-bit kernel option is unset/deactivated (CONFIG_64BIT=N), and then select the processor family as appropriate for the system's processor(s).
The processor family can be determined by reviewing output from the following two commands:
user $
cat /proc/cpuinfo | grep -i vendor | uniq
user $
cat /proc/cpuinfo | grep -i 'model name' | uniq

Compiling and installing
With the configuration now done, it is time to compile and install the kernel. Exit the configuration and start the compilation process:
root #
make && make modules_install
Nota
It is possible to enable parallel builds using make -j N with N being an integer number of parallel tasks that the build process is allowed to launch. This is similar to the instructions about /etc/portage/make.conf earlier, with the MAKEOPTS variable.

When the kernel has finished compiling, copy the kernel image to /boot/. This is handled by the make install command:
root #
make install
This will copy the kernel image into /boot/ together with the System.map file and the kernel configuration file.
