Summary: access_ok is called in atomic contexts in blackfin

Details:

 

access_ok is only for user context, but blackfin calls it in atomic context, like traps(arch/blackfin/kernel/traps.c).

That needs be fixed.

 

Follow-ups

Although blackfin adds addition check in access_ok, we have no intention to

restore a standard one until real bugs caused by this checking is reported.
