asm/serial.h is supposed to contain the definitions for the architecture specific 8250 ports for the 8250 driver. It may also define BASE_BAUD, but this is the base baud for the architecture specific ports _only_. Therefore, nothing other than the 8250 driver should be including this header file. In order to move towards this goal, here is a patch which removes some of the more obvious incorrect includes of the file. MIPS and PPC has rather a lot of stuff in asm/serial.h, some of it looks related to non-8250 ports. Hence, it's not trivial to conclude that these includes are indeed unnecessary, so can mips and ppc people please test this patch carefully.
