blk-settings.c integer truncation

[Sergey Senozhatsky]

Hello.
I was asking
> Should BLK_BOUNCE_ANY be (-1UL)?

No. It should not.

git annotate gives for blkdev.h:
Andi Kleen     2008-04-21 09:51:05 +0200       705)#define BLK_BOUNCE_ANY              (-1ULL)
...

...
(Martin K. Petersen     2009-05-22 17:17:51 -0400       311)    unsigned long           bounce_pfn;
...
(Martin K. Petersen     2009-05-22 17:17:50 -0400       1020)static inline unsigned long queue_bounce_pfn(struct request_queue *q)
(Martin K. Petersen     2009-05-22 17:17:50 -0400       1021){
(Martin K. Petersen     2009-05-22 17:17:51 -0400       1022)   return q->limits.bounce_pfn;
(Martin K. Petersen     2009-05-22 17:17:50 -0400       1023)}
...

I think, commit need to be reworked a bit.
