And neither does it give you permission to send such an idiotic and
rediculous email.
I'm not going to do anything about it because "Thomas Glexiner" has
suddenly decided he doesn't like it.
As for your definition of "hotpath", you're really screwed on that
because you don't seem to understand what is or isn't the hotpath in
this code.
So there's not much point discussing this with you until you:
(a) calm down
(b) analyse it properly and work out the frequency under which each
class of IRQ (those >= 32 and those < 32) call into these functions.
To put it bluntly, you're wrong.
