Thanks, will check. | | Ingo | Darn, my fault sorry! Here is an update which fixes the issue. (Btw, Stephen could you CC me next time if you get commit id with me in authors, so I wouldn't miss problem). Please review, comments/complains are quite welcome! -- Cyrill --- x86,apic: Get rid of apicid_to_cpu_present assign on X86-64 In fact it's never get used on x86-64 (for 64 bit platform we use differ technique to enumerate io-units).
