17 You do. It's called x86_64 in kernel-speak :-)
18
19 gentoo calls it amd64

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