Hi Kefeng, What you could do is to define a __weak function that architectures can override and call that function from mm_init() as suggested by Mike,
The problem with weak functions is that they bloat the kernel. Each time a weak function is overriden, it becomes dead unreachable code within the kernel image. At some point we're probabily going to have to enable -ffunction-sections to (hopefully) allow the dead code to be discarded. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
