Blackfin arch: fix bug - MPU crashes under stress
Bug Description:
a customer reported under IRQ stress, running applications may
wrongly trigger an ICPLB miss and be killed. after playing a
bit more, here's a test case that may be triggering the same bug.
Fixing:
After modifying page protections, only modify the active CPLBs if the
protection change was made for the active mm.
