[patch] fix "struct irq_desc"

In linux-2.6.0-test2-ia64-030729 configured for generic ia64,
asm-ia64/machvec.h returns a 'struct irq_desc'. There is a forward
declaration for the struct, but it is never actually defined under
that name, only as irq_desc_t.

This means that the type of ia64_mv_irq_desc is wrong, which causes
the build to break in some files that are built with -Werror. Really
this is incorrect even for non-generic builds although it does not
actually fail.

This patch puts in both the struct name and _t name:

--- linux-2.6.0test2-ia64/include/linux/irq.h.~1~ 2003-07-29 12:05:34.000000000 +1000

*/
-typedef struct {
+typedef struct irq_desc {
unsigned int status; /* IRQ status */
hw_irq_controller *handler;
struct irqaction *action; /* IRQ action list */

Perhaps it would be better to make everything use the irq_desc_t name?
That would require a somewhat larger rearrangement of the headers to
make it visible at that point, but I can do that if desired.
