 /* 
  * Authors:    Bjorn Wesen (bjornw@axis.com)
  *	       Hans-Peter Nilsson (hp@axis.com)
- *
- * $Log: uaccess.h,v $
- * Revision 1.8  2001/10/29 13:01:48  bjornw
- * Removed unused variable tmp2 in strnlen_user
- *
- * Revision 1.7  2001/10/02 12:44:52  hp
- * Add support for 64-bit put_user/get_user
- *
- * Revision 1.6  2001/10/01 14:51:17  bjornw
- * Added register prefixes and removed underscores
- *
- * Revision 1.5  2000/10/25 03:33:21  hp
- * - Provide implementation for everything else but get_user and put_user;
- *   copying inline to/from user for constant length 0..16, 20, 24, and
- *   clearing for 0..4, 8, 12, 16, 20, 24, strncpy_from_user and strnlen_user
- *   always inline.
- * - Constraints for destination addr in get_user cannot be memory, only reg.
- * - Correct labels for PC at expected fault points.
- * - Nits with assembly code.
- * - Don't use statement expressions without value; use "do {} while (0)".
- * - Return correct values from __generic_... functions.
- *
- * Revision 1.4  2000/09/12 16:28:25  bjornw
- * * Removed comments from the get/put user asm code
- * * Constrains for destination addr in put_user cannot be memory, only reg
- *
- * Revision 1.3  2000/09/12 14:30:20  bjornw
- * MAX_ADDR_USER does not exist anymore
- *
- * Revision 1.2  2000/07/13 15:52:48  bjornw
- * New user-access functions
- *
- * Revision 1.1.1.1  2000/07/10 16:32:31  bjornw
- * CRIS architecture, working draft
