Linux LTS Raring

[MR ZenWiz]

Is this package available in the 64-bit for x86_64 machines available?

Synaptic doesn't show any bitness for the linux-lts-raring packages,
and the page at
http://www.ubuntuupdates.org/package/core/precise/main/proposed/linux-lts-raring
only talks about 32-bit packages.

I'm curious in part because I like the more recent kernels and I'm
thinking of trying this out.

I'm running Xubuntu 12.04 x86_64 with all the (usual) latest updates.

Do I need anything else to upgrade my kernel?

Thanks.
