2005-09-12[PATCH] x86-64: Don't trust boot_cpu_id in the mptable.Andi Kleen
It could be wrong for kexec or other cases. Read it from the CPU instead. Signed-off-by: Murali <muralim@in.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-12[PATCH] x86-64: Don't assume APIC for boot processor has an APIC ID of zeroAndi Kleen
Originally from Stuart Hayes. When setting up the APIC for the Uniprocessor kernel don't assume the CPU has an APIC ID of zero. This fixes boot with the UP kernel on Dell PowerEdge 6800/6850 4way systems. Cc: Stuart.Hayes@dell.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-25[PATCH] kexec: x86_64: restore apic virtual wire mode on shutdownEric W. Biederman
When coming out of apic mode attempt to set the appropriate apic back into virtual wire mode. This improves on previous versions of this patch by by never setting bot the local apic and the ioapic into veritual wire mode. This code looks at data from the mptable to see if an ioapic has an ExtInt input to make this decision. A future improvement is to figure out which apic or ioapic was in virtual wire mode at boot time and to remember it. That is potentially a more accurate method, of selecting which apic to place in virutal wire mode.

2005-06-25[PATCH] x86_64: Change init sections for CPU hotplug supportAshok Raj
This patch adds __cpuinit and __cpuinitdata sections that need to exist past boot to support cpu hotplug. Caveat: This is done *only* for EM64T CPU Hotplug support, on request from Andi Kleen. Much of the generic hotplug code in kernel, and none of the other archs that support CPU hotplug today, i386, ia64, ppc64, s390 and parisc dont mark sections with __cpuinit, but only mark them as __devinit, and __devinitdata. If someone is motivated to change generic code, we need to make sure all existing hotplug code does not break, on other arch's that dont use __cpuinit, and __cpudevinit.

2005-05-17[PATCH] x86_64: Collected NMI watchdog fixes.Andi Kleen
Collected NMI watchdog fixes. - Fix call of check_nmi_watchdog - Remove earlier move of check_nmi_watchdog to later. It does not fix the race it was supposed to fix fully. - Remove unused P6 definitions - Add support for performance counter based watchdog on P4 systems. This allows to run it only once per second, which saves some CPU time. Previously it would run at 1000Hz, which was too much. Code ported from i386 Make this the default on Intel systems. - Use check_nmi_watchdog with local APIC based nmi - Fix race in touch_nmi_watchdog - Fix bug that caused incorrect performance counters to be programmed in a few cases on K8. - Remove useless check for local APIC - Use local_t and per_cpu variables for per CPU data. - Keep other CPUs busy during check_nmi_watchdog to make sure they really tick when in lapic mode. - Only check CPUs that are actually online. - Various other fixes. - Fix fallback path when MSRs are unimplemented Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Use bitmap_zero instead of bitmap_empty to initialise cpu mask This makes it actually run reliable instead of relying on stack state.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
