well, let's agree on this. I agree with Linus that the latest version of
/dev/microcode patch is ok, so if he accepts it as is (i.e. a char misc
driver on minor=184) it will be fine.

I also can save a minor number and implement the /proc/driver/microcode.

I cannot (right now) implement a devfs-aware version /dev/cpu/microcode
because I have not looked at Richard's devfs stuff yet.

Of Linus' /proc/driver vs /dev argument I understood b) but not a) or
c). Namely,

a) there is still userspace setup of using ioct on a proc file

c) whether kernel has update support or not is determined by whether
the minor=184 is accessible (perhaps by loading a driver) or not.
/proc does not make things much easier.

but he is right on b) - it saves a minor.

Regards,
Tigran.
