AMD and 2.6 kernel

[sting sting]

Hello,
I am reposting this message because the subject was erronously omitted;
I had looked in the kernel 2.6 source tree for sources of AMD 64 bit 
implementation
and I could not find; for example, under "arch", there are some folders of
different cpu types (like PPC,ARM,etc.) but there is no folder which is 
named AMD.

There is x86_64 folder under arch (and inside there is ia32) which I suspect 
may be the one
but I am not sure.
Can anybody shed a little light on it ?


Why there is no "AMD-64" folder?
or : where are the AMD 64 sources in the 2.6 kernel tree ?


regards,
sting
