I've gone through these patches and I can see that they are really needed for SMP where address spaces are shared. There are details I didn't get, such as where is the per-processor pde pointed, (i.e. where is the per processor KVM range) and is there a single page table for each processor that is always mapped into the processor specific slot for that process. another question that is raised I guess is how do we tell gdb to switch between processors when reading core-dumps :-).
