Ошибки после компиляции ядра

Доброго дня всем.
Недавно пересобрал ядро,но,когда оно закончило компилироваться, написало об ошибках,а когда конфигурировал grub2 тоже писало об ошибках.Все работает, но эти ошибки не дают мне покоя.Что делать?

*** End of the configuration.
*** Execute 'make' to start the build or try 'make help'.

*     one specified in /etc/fstab
*
* If you require Genkernel's hardware detection features; you MUST
* tell your bootloader to use the provided INITRAMFS file.

* WARNING... WARNING... WARNING...
* Additional kernel cmdline arguments that *may* be required to boot properly...
* With support for several ext* filesystems available, it may be needed to
* add "rootfstype=ext3" or "rootfstype=ext4" to the list of boot parameters.

* Do NOT report kernel bugs as genkernel bugs unless your bug
* is about the default genkernel configuration...
*
* Make sure you have the latest ~arch genkernel before reporting bugs.
