The function flush_switched_dcplbs was clearing the CPLB entries covering
the process permission bitmasks. This means that the sequence
flush_switched_dcplbs ();
set_mask_dcplbs(mm->context.page_rwx_mask);
has a problem: if kernel code (such as an interrupt) causes a CPLB miss before
set_mask_dcplbs completes, the CPLB handler function causes a double fault,
with an instantaneous reboot.
This bug fix is dedicated to Michael Hennerich, the only person in the world
capable of providing working JTAG hardware.
