You're right. It's not a problem. The code that disables interrupts right
here in drivers/pci/pci.c:
#define PCI_OP(rw,size,type) \
int pci_##rw##_config_##size (struct pci_dev *dev, int pos, type value) \
{ \
int res; \
unsigned long flags; \
if (PCI_##size##_BAD) return PCIBIOS_BAD_REGISTER_NUMBER; \
spin_lock_irqsave(&pci_lock, flags); \
res = dev->bus->ops->rw##_##size(dev, pos, value); \
spin_unlock_irqrestore(&pci_lock, flags); \
return res; \
}
I don't know why I missed that...
Thanks for the reply!
