has been removed from the -mm tree.  Its filename is

     m68k-atari-interrupt-updates.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: m68k/Atari: Interrupt updates
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>

Misc Atari fixes:
  - initialize correct number of atari irqs
  - silence vbl interrupt until it's used by atafb
  - use mdelay() to read clock if necessary
