Enable TTY to prevent a build error. Signed-off-by: Josh Triplett --- Not tested, but this *should* fix the build error with CONFIG_TTY=n. Minimal fix, on the basis that few people on ia64 will care deeply about kernel size enough to turn off TTY. Ideally, I'd instead suggest dropping the tty_write_message entirely, and just leaving the printk. Bonus: no need to sprintf first. arch/ia64/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/ia64/Kconfig b/arch/ia64/Kconfig index 0c8e553..6b83c66 100644 --- a/arch/ia64/Kconfig +++ b/arch/ia64/Kconfig @@ -44,6 +44,7 @@ config IA64 select HAVE_MOD_ARCH_SPECIFIC select MODULES_USE_ELF_RELA select ARCH_USE_CMPXCHG_LOCKREF + select TTY default y help The Itanium Processor Family is Intel's 64-bit successor to -- 1.9.0
