Hi Fengguang,
I don't think this is right. It can't be a 14 month old change.
The 2nd error itself totally smells like uapi changes.
The 1st error makes no sense at all when you look at this:
config SERIAL_8250_RUNTIME_UARTS
int "Number of 8250/16550 serial ports to register at runtime"
depends on SERIAL_8250
How can you build 8250 support and not have a value for the
number of runtime UARTs, given the above?
I also just checked that mainline v3.9-rc4-158-g9064171 has no
problems building drivers/tty/* for s390 while x-compiling in
my local test of allmodconfig.
Paul.
