KDB_ENTER & interrupt level

[Steven Bytnar]

There's a comment in asm-i386/kdb.h regarding KDB_ENTER that says:

"If it is intended to be used from interrupt level, it must
use a non-maskable entry method."

Is that describing a kernel developer's view of using KDB_ENTER, or
is this describing how someone should implement it for other
architectures?
In other words, if I want to call KDB_ENTER from an arbitrary kernel
module at interrupt level, do I need to take special precautions? Or
was the comment aimed at people porting KDB to other architectures?

Thanks,
