With CONFIG_KALLSYMS_ALL=y, the function is_ksym_addr() is used to
determine if a symbol is from inside the kernel range. For that the
given symbol address is checked if it's inside the _stext to _end range.
Although this is correct, some architectures (e.g. parisc) may have the
init area before the _stext address and as such the check in
is_ksym_addr() fails. By extending the range check to include the init
section, __is_kernel() will now detect symbols in this range as well.
This fixes an issue on parisc where addresses of kernel functions in
init sections aren't resolved to their symbol names.
