AFAIK, the amd64 architecture is always referred to as x86_64, so that folder 
under arch is where I expect your built kernel will be. As for the "amd64 
sources", they are the same as the ppc sources, the i386 sources etc. the 
only arch-dependant stuff will be the assembly, which is under it's own set 
of subdirectories.

Don't take me as an authoritative source though. I am replying because your 
query appears under-researched, so is unlikely to attract attention from the 
gurus until it displays some evidence of your having done some further 
digging. Hopefully this summary will help: "amd64 is called x86_64. Kernel 
sources are the same for all architectures, but some routines done in 
assembly are placed in architecture-dependant trees".

I hope that helps.
