[PATCH v1 1/3] perf: MAP_EXECUTABLE does not indicate VM_MAYEXEC

[David Hildenbrand]

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.

Fixes: f972eb63b100 ("perf: Pass protection and flags bits through mmap2 interface")
