The new architecture name is lpia, this needs to be put into archtable in dpkg and apt.
Architecture needs to be added to soyuz and buildds set up.
Spec/default compilation flags to be provided by Intel. -mtune=pentium and gcc-4.1 is appropriate and gets us the needed optimisations.
The toolchain, including the headers from the kernel, is built and uploaded (usual two-stage bootstrapping procedure). Since it's binary compatible with ia32 we will use that as a base rather than cross-compiling.
Architecture is hooked into the normal build system and packages built there as usual.
Packages-arch-Specific needs to have lpia added to it for packages that we want on lpia.
A number of source packages require changes to debian/control to have lpia added to their Architecture line, as well as adjustments to debian/rules.
