x86/vm86: Fix unused variable warning if THP is disabled GCC complains about unused variable 'vma' in mark_screen_rdonly() if THP is disabled: arch/x86/kernel/vm86_32.c: In function ‘mark_screen_rdonly’: arch/x86/kernel/vm86_32.c:180:26: warning: unused variable ‘vma’ [-Wunused-variable] struct vm_area_struct *vma = find_vma(mm, 0xA0000); That's silly. pmd_trans_huge() resolves to 0 when THP is disabled, so the whole block should be eliminated. Moving the variable declaration outside the if() block shuts GCC up. Reported-by: Jérémy Lefaure <jeremy.lefaure@lse.epita.fr> Signed-off-by: Kirill A.
