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)
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..
