[PATCH] 2.5.6 PPP deflate breakage on UP

[Mikael Pettersson]

In kernel 2.5.6, PPP deflate isn't compiled correctly if CONFIG_SMP
is off: the macros local_bh_enable() and local_bh_disable() aren't
expanded and instead turn into references to undefined functions.
The problem is that <linux/smp_lock.h> is insufficient in UP configs.

The patch below adds an #include <linux/interrupt.h> which works
around this. I'm not sure about <linux/smp_lock.h>: it really doesn't
look appropriate for the locking primitives being used in ppp_deflate.c.
