perf: MAP_EXECUTABLE does not indicate VM_MAYEXEC
Patch series "perf/binfmt/mm: remove in-tree usage of MAP_EXECUTABLE".
Stumbling over the history of MAP_EXECUTABLE, I noticed that we still have
some in-tree users that we can get rid of.
This patch (of 3):
Before commit e9714acf8c43 ("mm: kill vma flag VM_EXECUTABLE and
mm->num_exe_file_vmas"), VM_EXECUTABLE indicated MAP_EXECUTABLE.
MAP_EXECUTABLE is nowadays essentially ignored by the kernel and does not
relate to VM_MAYEXEC.
