[PATCH v2 0/4 - gnumach] SMP almost working!

[Damien Zammit]

Hi,

This patchset applies to master and has been tested
not to break --{enable,disable}-kdb --disable-pae --disable-apic
while getting closer to a working SMP version.

I did not test all patches in isolation, only the combination of 4.

In particular, it adds separate interrupt stacks per cpu, descriptor
table loading per cpu, and a refactoring of temporary pmap functions.
