5e9e7687cb Blackfin arch: Fix BUG -- BF533 + 0.5 silicon + MPU + UART PIO -> crash 
Apply ANOMALY_05000283 & ANOMALY_05000315
Workaround also to the EXCEPTION path.

Cover evt_ivhw also with ANOMALY_05000315
The Workaround needs to be prior to accesses (either read or write) to
any system MMR.

226a6ec311 Blackfin arch: sram: use 'unsigned long' for irqflags 
Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.

The patch was generated using the Coccinelle semantic patch framework.
