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.
