[PATCH 21/24] make atomic_read() behave consistently on v850

From: Chris Snook <[EMAIL PROTECTED]> Make atomic_read() volatile on v850. This ensures that busy-waiting for an interrupt handler to change an atomic_t won't get compiled to an infinite loop, consistent with SMP architectures. Signed-off-by: Chris Snook <[EMAIL PROTECTED]> ---
