2016-12-19x86/asm: Rewrite sync_core() to use IRET-to-selfAndy Lutomirski
Aside from being excessively slow, CPUID is problematic: Linux runs on a handful of CPUs that don't have CPUID. Use IRET-to-self instead. IRET-to-self works everywhere, so it makes testing easy. For reference, On my laptop, IRET-to-self is ~110ns, CPUID(eax=1, ecx=0) is ~83ns on native and very very slow under KVM, and MOV-to-CR2 is ~42ns. While we're at it: sync_core() serves a very specific purpose. Document it.

2016-12-19x86/microcode/intel: Replace sync_core() with native_cpuid()Andy Lutomirski
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.

2016-12-19Revert "x86/boot: Fail the boot if !M486 and CPUID is missing"Andy Lutomirski
This reverts commit ed68d7e9b9cfb64f3045ffbcb108df03c09a0f98. 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.

2016-12-19x86/unwind: Adjust last frame check for aligned function stacksJosh Poimboeuf
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.

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.

2016-12-19x86/microcode/AMD: Use native_cpuid() in load_ucode_amd_bsp()Boris Ostrovsky
When CONFIG_PARAVIRT is selected, cpuid() becomes a call. Since for 32-bit kernels load_ucode_amd_bsp() is executed before paging is enabled the call cannot be completed (as kernel virtual addresses are not reachable yet).

2016-12-19x86/microcode/AMD: Do not load when running on a hypervisorBorislav Petkov
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.

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.

2016-12-18x86/tsc: Limit the adjust value furtherThomas Gleixner
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.

2016-12-17x86/mpx: Move bd_addr to mm_context_tMark Rutland
Currently bd_addr lives in mm_struct, which is otherwise architecture independent. Architecture-specific data is supposed to live within mm_context_t (itself contained in mm_struct). Other x86-specific context like the pkey accounting data lives in mm_context_t, and there's no readon the MPX data can't also live there. So as to keep the arch-specific data togather, and to set a good example for others, this patch moves bd_addr into x86's mm_context_t.

2016-12-16tile: use __ro_after_init instead of tile-specific __write_onceChris Metcalf
The semantics of the old tile __write_once are the same as the newer generic __ro_after_init, so rename them all and get rid of the tile-specific version. This does not enable actual support for __ro_after_init, which had been dropped from the tile architecture before the initial upstreaming was done, since we had at that time switched to using 16MB huge pages to map the kernel.

We've now separated that content out into its own file "extable.h" so now move over to that and avoid all the extra header content in module.h that we don't really need to compile these files.

2016-12-16tile: remove #pragma unroll from finv_buffer_remote()Chris Metcalf
This directive was put in the kernel source before the "pragma unroll" support for tilegx gcc was upstreamed. Remove it for now, and we can put it back later if/when the compiler support is upstreamed. This avoids a warning when building the kernel. This routine is not on a hot path in any case, so the extra optimization here was mostly just for its own sake. Signed-off-by: Chris Metcalf <cmetcalf@mellanox.com>
