函数名称：eisa_bus_probe

函数原型：static __init int eisa_bus_probe(void)

返回类型：int

参数：无

13  __iomem乘p
15  如果xen_pv_domain()且非xen_initial_domain()则返回:0
18  p等于remap - map bus memory into CPU space*@offset: bus address of the memory*@size: size of the resource to map* ioremap performs a platform specific sequence of operations to* make bus memory CPU accessible via the readb/readw/readl/writeb/
19  如果p且readl(p)恒等于'E'加'I'左移8位的值加'S'左移16位的值加'A'左移24位的值则EISA_bus等于1
21  iounmap(p)
22  返回:0
