[PATCH]arch:x86:kvm:i8254.h Fix typo in kvm_pit

[Justin P. Mattock]

The below patch changes base_addresss to base_address.
Note: I have grepped for base_addresss and nothing shows up,
grepping for base_address gets me lots of output, telling me that
this is a typo, but could be wrong.

Why not remove the variable completely?

didnt even think to completely remove the variable(figured it was used 
somewhere).I will look at that and resend with removal of the variable 
for you..

Well if it was used, you ought to have changed all of the users, no?

at the moment I see:
(keep in mind my reading skills only go so far!)

  grep -Re base_address kvm/* -n
kvm/ioapic.c:276:       return ((addr >= ioapic->base_address &&
kvm/ioapic.c:277:                (addr < ioapic->base_address + 
IOAPIC_MEM_LENGTH)));
kvm/ioapic.c:371:       ioapic->base_address = IOAPIC_DEFAULT_BASE_ADDRESS;
kvm/ioapic.h:38:        u64 base_address;

so changing base_addresss; to base_address; gets kvm_ioapic_reset to 
function correctly as well as ioapic_in_range?
(but could be wrong)

I am afraid Justin is not trying to compile-test his patches (I got this 
suspicion after last patchset trying to remove all the includes of 
version.h).

I do remember to do that, but I will be honest there are ones that I 
totally forgot, then remembered after sending out the patch(I admit it I 
am guilty of that)

Think having a checklist is the best thing to follow when doing a patch
(telling yourself "yeah Ill remember to do that", never is the best way.

Can you explain how kvm_ioapic_reset() would be affected by the change?

Really, you need to understand what you're doing before sending patches.

well looking at the code:
virt/kvm/ioapic.c @@276

static inline int ioapic_in_range(struct kvm_ioapic *ioapic, gpa_t addr)
{
	return ((addr >= ioapic->base_address &&
		 (addr < ioapic->base_address + IOAPIC_MEM_LENGTH)));
}

I see: base_address in there but looking more at the code its for 
something completely different..
