Re: [powerpc] Fix bogus BUG_ON() in in hugetlb_get_unmapped_area()

+ if (len > TASK_SIZE)
+ return -ENOMEM;

Shouldn't that be addr+len instead? The check looks incomplete
otherwise. And you meant ">=" I guess?

- /* Paranoia, caller should have dealt with this */
- BUG_ON((addr + len) > 0x100000000UL);
-

Any real reason to remove the paranoia check? If it's trivially
always satisfied, the compiler will get rid of it for you :-)

Cheers,
