2008-04-24	[Blackfin] arch: fix bug - a crash on bootup with CONFIG_MPU on the BF548	Bernd Schmidt
	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.
