int core_kernel_data

(

unsigned long

addr

)

core_kernel_data - tell if addr points to kernel data : address to test

Returns true if passed in is from the core kernel data section.

Note: On some archs it may return true for core RODATA, and false for others. But will always be true for core RW data.
