Hello Alex, I found where the error is, but there's a problem here:
config PORTABLE bool default !NONPORTABLE select EFI select MMU select OF select HAVE_DYNAMIC_FTRACE if !XIP_KERNEL && MMU && (CLANG_SUPPORTS_DYNAMIC_FTRACE || GCC_SUPPORTS_DYNAMIC_FTRACE) Because HAVE_DYNAMIC_FTRACE depends on the MMU—of course, it's reasonable for DYNAMIC_FTRACE to depend on the MMU—*but since NONPORTABLE is enabled by default, this causes PORTABLE to default to n, thereby preventing the MMU from being enabled*. So, should I change NONPORTABLE to default to n?
