Subject: [PATCH] useless includes of linux/irq.h in arch/i386

	Most of these guys are simply not needed (pulled by other stuff
via asm-i386/hardirq.h).  One that is not entirely useless is hilarious -
arch/i386/oprofile/nmi_timer_int.c includes linux/irq.h... as a way to
get linux/errno.h

Subject: [PATCH] Fix up TLB flush filter disabling

I checked with AMD and they requested to only disable it for family 15.
Also disable it for i386 too. And some style fixes.

Subject: [PATCH] i386: include linux/irq.h rather than asm/hw_irq.h

I need the following patch to compile -git8 here, otherwise these
files fail to compile (asm/hw_irq.h needs definitions from
linux/irq.h and that file provides the required include ordering).

I did not do a full audit, though there looks to be many other
places that should get the same treatment, if this is  the right
way to do it.
