[ARM] 3399/1: Fix link problem when CONFIG_PRINTK is disabled
Patch from Malcolm Parsons Printking a backtrace requires printk, so disable backtrace code when printk is disabled. Without this patch, a kernel with CONFIG_PRINTK disabled does not link: arch/arm/lib/lib.a(backtrace.o): In function `c_backtrace': arch/arm/lib/backtrace.S:(.text+0x108): undefined reference to `printk' arch/arm/lib/backtrace.S:(.text+0x11c): undefined reference to `printk' arch/arm/lib/lib.a(backtrace.o):(.fixup+0x8): undefined reference to `printk' Signed-off-by: Malcolm Parsons <malcolm.parsons@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
