I just worked up the below.  I set the key combo As C-x v, which is
unused by default.  However, you can change it.  Put it in ~/.emacs:

(defun refresh-all-buffers ()
"Refreshes all buffers from disk"
(interactive)
(mapc
 (lambda (buffer)
   (if (buffer-file-name buffer)
   (find-alternate-file (buffer-file-name buffer))))
 (buffer-list)))

(global-set-key [?\C-x ?v] 'refresh-all-buffers)
