From 45e55300f11495ed58c53427da7f0d958800a30f Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Thu, 6 Aug 2020 23:23:37 -0700 Subject: mm: remove unnecessary wrapper function do_mmap_pgoff() The current split between do_mmap() and do_mmap_pgoff() was introduced in commit 1fcfd8db7f82 ("mm, mpx: add "vm_flags_t vm_flags" arg to do_mmap_pgoff()") to support MPX. The wrapper function do_mmap_pgoff() always passed 0 as the value of the vm_flags argument to do_mmap(). However, MPX support has subsequently been removed from the kernel and there were no more direct callers of do_mmap(); all calls were going via do_mmap_pgoff(). Simplify the code by removing do_mmap_pgoff() and changing all callers to directly call do_mmap(), which now no longer takes a vm_flags argument.
