The is_kernel[_text]() function check the address whether or not
in kernel[_text] ranges, also they will check the address whether

Do you know what a gate area is?

Because I believe gate area is kernel text, so the rename just makes it
redundant and more confusing.

Yes, the gate area(eg, vectors part on ARM32, similar on x86/ia64) is kernel text.

I want to keep the 'basic' section boundaries check, which only check the start/end

of sections, all in section.h,  could we use 'generic' or 'basic' or 'core' in the naming?

* is_kernel_generic_data() --- come from core_kernel_data() in kernel.h
* is_kernel_generic_text()

The old helper could remain unchanged, any suggestion, thanks.
