[ARM] 3853/1: Fix flush_ptrace_access() thinko for nonaliasing VIPT cache case
Fix thinko in the flush_ptrace_access() "if (expr)" for the ARM VIPT non-aliasing cache case. We only need to flush cache when VM_EXEC is set in vma->vm_flags but "if (expr) always evaluates to true on UP systems for the ARM VIPT non-aliasing cache case. Signed-off-by: George G.
