x86: Stop MCEs and NMIs during code patching

2007-07-22T18:03:37Z

When a machine check or NMI occurs while multiple byte code is patched the CPU could theoretically see an inconsistent instruction and crash. Prevent this by temporarily disabling MCEs and returning early in the NMI handler. Based on discussion with Mathieu Desnoyers.

x86: round_jiffies() for i386 and x86-64 non-critical/corrected MCE polling

2007-07-22T01:37:10Z

This helps to reduce the frequency at which the CPU must be taken out of a lower-power state. Signed-off-by: Venkatesh Pallipadi Acked-by: Tim Hockin Signed-off-by: Andrew Morton Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

HOTPLUG: Adapt thermal throttle to CPU_DYING

2007-07-16T09:05:50Z

CPU_DYING is notified in atomic context, so no taking mutexes here. Signed-off-by: Avi Kivity

i386: Clear MCE flag on AMD K6

2007-05-21T16:56:57Z

It reports machine check capability in CPUID, but doesn't actually implement all the necessary MSRs of the standard Intel machine check architecture. This fixes a boot failure on K6s recently introduced. Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

Add suspend-related notifications for CPU hotplug

2007-05-09T19:30:56Z

Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

[PATCH] i386: check capability

2007-05-02T17:27:18Z

Currently the i386 architecture checks the family for mce capability and this removes that and uses the CPUID information. Tested on a K8 revE and a family10h processor. This eliminates checking of a set AMD procesor family if mce is allowed and relies on the information being in CPUID.

[PATCH] i386: Clean up arch/i386/kernel/cpu/mcheck/p4.c

2007-05-02T17:27:16Z

No, just no. You do not use goto to skip a code block. You do not return an obvious variable from a singly-inlined function and give the function a return value. You don't put unexplained comments about kmalloc in code which doesn't do dynamic allocation. And you don't leave stray warnings around for no good reason. Also, when possible, it is better to use block scoped variables because gcc can sometime generate better code. Signed-off-by: Zachary Amsden Signed-off-by: Andi Kleen
