/*************************** error 1 ******************************/ 在编译内核的过程中出现了如下的编译显示代码：
drivers/video/console/vgacon.c: In function 'vgacon_startup':
drivers/video/console/vgacon.c:510: error: 'PCIMEM_BASE' undeclared (first use in this function)
drivers/video/console/vgacon.c:510: error: (Each undeclared identifier is reported only once
drivers/video/console/vgacon.c:510: error: for each function it appears in.)
drivers/video/console/vgacon.c: In function 'vgacon_do_font_op':
drivers/video/console/vgacon.c:1068: error: 'PCIMEM_BASE' undeclared (first use in this function)
make[3]: *** [drivers/video/console/vgacon.o] Error 1
make[2]: *** [drivers/video/console] Error 2
make[1]: *** [drivers/video] Error 2
make: *** [drivers] Error 2
说明：配置单中对于控制台的配置有误，添加了多余的配置导致的。
解决方法：通过make menuconfig 进入配置界面，在Device Drivers->Graphics Support->Console display driver support中去掉VGA text console,保存设置后再编译就可以了
