The Intel microcode driver is using sync_core() to mean "do CPUID with EAX=1". I want to rework sync_core(), but first the Intel microcode driver needs to stop depending on its current behavior.

This reverts commit ed68d7e9. The patch wasn't quite correct -- there are non-Intel (and hence non-486) CPUs that we support that don't have CPUID. Since we no longer require CPUID for sync_core(), just revert the patch. I think the relevant CPUs are Geode and Elan, but I'm not sure. In principle, we should try to do better at identifying CPUID-less CPUs in early boot, but that's more complicated.

Somehow, CONFIG_PARAVIRT=n convinces gcc to change the x86_64_start_kernel() prologue from: 0000000000000129 <x86_64_start_kernel>: 129: 55 push %rbp 12a: 48 89 e5 mov %rsp,%rbp to: 0000000000000124 <x86_64_start_kernel>: 124: 4c 8d 54 24 08 lea 0x8(%rsp),%r10 129: 48 83 e4 f0 and $0xfffffffffffffff0,%rsp 12d: 41 ff 72 f8 pushq -0x8(%r10) 131: 55 push %rbp 132: 48 89 e5 mov %rsp,%rbp This is an unusual pattern which aligns rsp (though in this case it's already aligned) and saves the start_cpu() return address again on the stack before storing the frame pointer. The unwinder assumes the last stack frame header is at a certain offset, but the above code breaks that assumption, resulting in the following warning: WARNING: kernel stack frame pointer at ffffffff82e03f40 in swapper:0 has bad value (null) Fix it by checking for the last task stack frame at the aligned offset in addition to the normal unaligned offset.

The error message "Can't read CTR while initializing i8042" appears on Cherry Trail-based devices at each boot time: i8042: PNP: No PS/2 controller found. Probing ports directly. i8042: Can't read CTR while initializing i8042 i8042: probe of i8042 failed with error -5 This happens because we historically do not trust firmware on X86 and, while noting that PNP does not show keyboard or mouse devices, we still charge ahead and try to probe the controller. Let's relax this a bit and if results of PNP probe agree with the results of platform initialization/quirks conclude that there is, in fact, no i8042. While at it, let's avoid using x86_platform.i8042_detect() and instead abort execution early if platform indicates that it can not possibly have i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

Add i8042 state to the platform data to help i8042 driver make decision whether to probe for i8042 or not. We recognize 3 states: platform/subarch ca not possible have i8042 (as is the case with Inrel MID platform), firmware (such as ACPI) reports that i8042 is absent from the device, or i8042 may be present and the driver should probe for it. The intent is to allow i8042 driver abort initialization on x86 if PNP data (absence of both keyboard and mouse PNP devices) agrees with firmware data. It will also allow us to remove i8042_detect later.

Doing so is completely void of sense for multiple reasons so prevent it. Set dis_ucode_ldr to true and thus disable the microcode loader by default to address xen pv guests which execute the AP path but not the BSP path. By having it turned off by default, the APs won't run into the loader either. Also, check CPUID(1).ECX[31] which hypervisors set. Well almost, not the xen pv one. That one gets the aforementioned "fix". Also, improve the detection method by caching the final decision whether to continue loading in dis_ucode_ldr and do it once on the BSP. The APs then simply test that value.

According to Microchip errata some combinations of date and month values may result in the date being reset to 1, even if the date is also written with the month (for example 31-07 or 31-08). As a workaround avoid writing date and month values within the same Write command. Instead, terminate the Write command after loading the date and begin a new command to write the month. In addition, disable the oscillator before loading the new values. This is done by ensuring both the ST and EXTOSC bits are cleared and waiting for the OSCON bit to clear.

Pull libnvdimm updates from Dan Williams: "The libnvdimm pull request is relatively small this time around due to some development topics being deferred to 4.11. As for this pull request the bulk of it has been in -next for several releases leading to one late fix being added (commit 868f036f ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It has received a build success notification from the 0day-kbuild robot and passes the latest libnvdimm unit tests. Summary: - Dynamic label support: To date namespace label support has been limited to disambiguating cases where PMEM (direct load/store) and BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since 4.9 added support for multiple namespaces per PMEM-region there is value to support namespace labels even in the non-aliasing case. The presence of a valid namespace index block force-enables label support when the kernel would otherwise rely on region boundaries, and permits the region to be sub-divided. - Handle media errors in namespace metadata: Complement the error handling for media errors in namespace data areas with support for clearing errors on writes, and downgrading potential machine-check exceptions to simple i/o errors on read. - Device-DAX region attributes: Add 'align', 'id', and 'size' as attributes for device-dax regions. In particular this enables userspace tooling to generically size memory mapping and i/o operations. Prevent userspace from growing assumptions / dependencies about the parent device topology for a dax region.

Pull timer updates from Thomas Gleixner: "This is the last functional update from the tip tree for 4.10. It got delayed due to a newly reported and anlyzed variant of BIOS bug and the resulting wreckage: - Seperation of TSC being marked realiable and the fact that the platform provides the TSC frequency via CPUID/MSRs and making use for it for GOLDMONT. - TSC adjust MSR validation and sanitizing: The TSC adjust MSR contains the offset to the hardware counter. The sum of the adjust MSR and the counter is the TSC value which is read via RDTSC. On at least two machines from different vendors the BIOS sets the TSC adjust MSR to negative values. This happens on cold and warm boot. While on cold boot the offset is a few milliseconds, on warm boot it basically compensates the power on time of the system. The BIOSes are not even using the adjust MSR to set all CPUs in the package to the same offset. The offsets are different which renders the TSC unusable, What's worse is that the TSC deadline timer has a HW feature^Wbug. It malfunctions when the TSC adjust value is negative or greater equal 0x80000000 resulting in silent boot failures, hard lockups or non firing timers. This looks like some hardware internal 32/64bit issue with a sign extension problem. Intel has been silent so far on the issue. The update contains sanity checks and keeps the adjust register within working limits and in sync on the package.

Adjust value 0x80000000 and other values larger than that render the TSC deadline timer disfunctional. We have not yet any information about this from Intel, but experimentation clearly proves that this is a 32/64 bit and sign extension issue. If adjust values larger than that are actually required, which might be the case for physical CPU hotplug, then we need to disable the deadline timer on the affected package/CPUs and use the local APIC timer instead. That requires some surgery in the APIC setup code, so we just limit the ADJUST register value into the known to work range for now and revisit this when Intel comes forth with proper information.

The build of sparc allmodconfig fails with the error: "of_irq_to_resource" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined! of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can safely use #if defined(CONFIG_OF_IRQ) in the code.
