[PATCH] fix ia64 compile failure with gcc4.1 

__get_unaligned creates a typeof the var its passed, and writes to it,
which on gcc4.1, spits out the following error:

drivers/char/vc_screen.c: In function 'vcs_write':
drivers/char/vc_screen.c:422: error: assignment of read-only variable 'val'

[ The "right" fix would be to try to fix <asm-generic/unaligned.h>
  but that's hard to do with the tools gcc gives us. So this
  simpler patch is preferable -- Linus ]
