approach, but that won't be a restriction for a while.
Now you can detect in the kernel calls likely to be from the final

You first need to get rid of any code that assumes that siget_t is an

though. Odd :)
Try disabling where it uses rtprio to set itself realtime and see if that
"fixes" it.

I wasn't aware of that.
I'd like to remove the rtprio call from ntpd. I thin
on but the headers might
be useful for.
I can imagine non-byte addressable floating point DSPs with
sizeof(char) == sizeof(double).
I won't complain about the headers in a machine subdirectory.

It's possible that the EC is solely responsible for the fan, or that
Sony decided in their infinite wisdom to do it all in a driver somewhere.
"acpiconf -s 1" switches the fan to its low setting, so we do know
how to do it.

Critique, please.
I have almost completely finished this work. Please join the
[EMAIL PROTECTED] mailing-list, where the patches were
posted several months ago, and where hopefully more discussion can
still
flag and then added
when handled.
Changing things to return NULL pointers in the kernel where they
never were before is equally lame. Without the appropriate work
you're just pushing the panic off to a hard to find location.
