You do. It's called x86_64 in kernel-speak :-)

gentoo calls it amd64

These days the 32 and 64 bits x86 trees have been merged into one,=20
called x86. The vast majority of the trees were the same with a few=20
differences here and there so a merge was appropriate and easier to=20
maintain. 64 bit x86 is really just an extension of 32 bit in terms of=20
the C code, it certainly isn't, and doesn't warrant, a different arch

=2D-=20
