The powerpc specific version of hugetlb_get_unmapped_area() makes some unwarranted assumptions about what checks have been made to its parameters by its callers. This will lead to a BUG_ON() if a 32-bit process attempts to make a hugepage mapping which extends above TASK_SIZE (4GB). I'm not sure if these assumptions came about because they were valid with earlier versions of the get_unmapped_area() path, or if it was always broken. Nonetheless this patch fixes the logic, and removes the crash. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org> |
