[PATCH] ia64: fix ia32 partial-page map support for overlapping mmaps
- Handle the overlapping mmaps in the MAP_FIXED case - Handle unmaps correctly i.e. call __ia32_delete_pp_range() - There are now three clear entry points into the pp manipulation code - ia32_set_pp - ia32_unset_pp - ia32_compare_pp - Rename internal functions to __ia32_*pp_* - Grab mmap_sem just once at the main entry point Signed-off-by: Gordon Jin <gordon.jin@intel.com> Signed-off-by: Arun Sharma <arun.sharma@intel.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com>
