I wonder where the fabrications for IBM are occurring?

The fabrications for IBM come from the corner office and the marketing
department.

The wafer spinning for z and p system processors is done in the same
IBM fabs that were used before the divestiture, the name on the buildings
and employee paychecks just changed from IBM to GF. Keep in mind IBM
MPUs are made in very expensive boutique SOI/trench eDRAM processes
no one else can afford. GF had agreed to support this very low volume
production for some years which is why IBM had to *pay* GF to take IBM
Semi off its hands. It isn't at all similar to GF's normal foundry business.
