Hi, thanks for working.

I got a linkage error, next;

arch/um/drivers/built-in.o: In function `line_ioctl':
/data/kernel/mainline/workdir/next/.branches/um/linux/arch/um/drivers/line.c:306: undefined reference to `tioclinux'
collect2: ld returned 1 exit status
  KSYM    .tmp_kallsyms1.S
nm: '.tmp_vmlinux1': No such file
No valid symbol.
make: *** [.tmp_kallsyms1.S] Error 1

The tioclinux() is in drivers/char/vt.c and this is compiled when
CONFIG_HW_CONSOLE is enabled. I think this config is never turned on in uml,
because of the following definition in drivers/char/Kconfig;

config HW_CONSOLE
	bool
	depends on VT && !S390 && !UML
	default y


thanks,
Hiroshi Shimamoto
