Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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.
As it looks like this disease is spreading via BIOS crapware, we
need to address this urgently as the boot failures are hard to
debug for users"

x86/tsc: Limit the adjust value further
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.

x86/mpx: Move bd_addr to mm_context_t
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.

powerpc updates for 4.10
Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for secure and
trusted boot.
- Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
- Sort the exception tables at build time, to save time at boot, and store
them as relative offsets to save space in the kernel image & memory.
- Allow building the kernel with thin archives, which should allow us to build
an allyesconfig once some other fixes land.
- Build fixes to allow us to correctly rebuild when changing the kernel endian
from big to little or vice versa.
- Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
- Initial stack protector support (-fstack-protector).
- Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
- Fix an oops in cxl coredump generation when cxl_get_fd() is used.
- Freescale updates from Scott: "Highlights include 8xx hugepage support,
qbman fixes/cleanup, device tree updates, and some misc cleanup."
- Many and varied fixes and minor enhancements as always.

x86/tsc: Force TSC_ADJUST register to value >= zero
Roland reported that his DELL T5810 sports a value add BIOS which completely wreckages the TSC. The squirmware [(TM) Ingo Molnar] boots with random negative TSC_ADJUST values, different on all CPUs. That renders the TSC useless because the sycnchronization check fails. Roland tested the new TSC_ADJUST mechanism. While it manages to readjust the TSCs he needs to disable the TSC deadline timer, otherwise the machine just stops booting. Deeper investigation unearthed that the TSC deadline timer is sensitive to the TSC_ADJUST value. Writing TSC_ADJUST to a negative value results in an interrupt storm caused by the TSC deadline timer. This does not make any sense and it's hard to imagine what kind of hardware wreckage is behind that misfeature, but it's reliably reproducible on other systems which have TSC_ADJUST and TSC deadline timer. While it would be understandable that a big enough negative value which moves the resulting TSC readout into the negative space could have the described effect, this happens even with a adjust value of -1, which keeps the TSC readout definitely in the positive space. The compare register for the TSC deadline timer is set to a positive value larger than the TSC, but despite not having reached the deadline the interrupt is raised immediately. If this happens on the boot CPU, then the machine dies silently because this setup happens before the NMI watchdog is armed. Further experiments showed that any other adjustment of TSC_ADJUST works as expected as long as it stays in the positive range. The direction of the adjustment has no influence either. See the lkml link for further analysis. Yet another proof for the theory that timers are designed by janitors and the underlying (obviously undocumented) mechanisms which allow BIOSes to wreckage them are considered a feature. Well done Intel - NOT! To address this wreckage add the following sanity measures: - If the TSC_ADJUST value on the boot cpu is not 0, set it to 0 - If the TSC_ADJUST value on any cpu is negative, set it to 0 - Prevent the cross package synchronization mechanism from setting negative TSC_ADJUST values.

x86/smpboot: Prevent false positive out of bounds cpumask access warning
prefill_possible_map() reinitializes the cpu_possible_map by setting the possible cpu bits and clearing all other bits up to NR_CPUS. This is technically always correct because cpu_possible_map is statically allocated and sized NR_CPUS. With CPUMASK_OFFSTACK and DEBUG_PER_CPU_MAPS enabled the bounds check of cpu masks happens on nr_cpu_ids. nr_cpu_ids is initialized to NR_CPUS and only limited after the set/clear bit loops have been executed. But if the system was booted with "nr_cpus=N" on the command line, where N is < NR_CPUS then nr_cpu_ids is limited in the parameter parsing function before prefill_possible_map() is invoked. As a consequence the cpumask bounds check triggers when clearing the bits past nr_cpu_ids. Add a helper which allows to reset cpu_possible_map w/o the bounds check and then set only the possible bits which are well inside bounds.

kexec: export the value of phys_base instead of symbol address
Currently in x86_64, the symbol address of phys_base is exported to vmcoreinfo. Dave Anderson complained this is really useless for his Crash implementation. Because in user-space utility Crash and Makedumpfile which exported vmcore information is mainly used for, value of phys_base is needed to covert virtual address of exported kernel symbol to physical address. Especially init_level4_pgt, if we want to access and go over the page table to look up a PA corresponding to VA, firstly we need calculate page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base; Now in Crash and Makedumpfile, we have to analyze the vmcore elf program header to get value of phys_base. As Dave said, it would be preferable if it were readily availabl in vmcoreinfo rather than depending upon the PT_LOAD semantics. Hence in this patch change to export the value of phys_base instead of its virtual address. And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64 only, should be moved into arch dependent function arch_crash_save_vmcoreinfo. Do the moving in this patch.

x86/boot/64: Push correct start_cpu() return address
start_cpu() pushes a text address on the stack so that stack traces from idle tasks will show start_cpu() at the end. But it currently shows the wrong function offset. It's more correct to show the address immediately after the 'lretq' instruction.

Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1. Big thing here is the nice addition of "functional dependencies" to the driver core. The idea has been talked about for a very long time, great job to Rafael for stepping up and implementing it. It's been tested for longer than the 4.9-rc1 date, we held off on merging it earlier in order to feel more comfortable about it. Other than that, it's just a handful of small other patches, some good cleanups to the mess that is the firmware class code, and we have a test driver for the deferred probe logic.

Pull power management updates from Rafael Wysocki:
"Again, cpufreq gets more changes than the other parts this time (one
new driver, one old driver less, a bunch of enhancements of the
existing code, new CPU IDs, fixes, cleanups)
There also are some changes in cpuidle (idle injection rework, a
couple of new CPU IDs, online/offline rework in intel_idle, fixes and
cleanups), in the generic power domains framework (mostly related to
supporting power domains containing CPUs), and in the Operating
Performance Points (OPP) library (mostly related to supporting devices
with multiple voltage regulators)
In addition to that, the system sleep state selection interface is
modified to make it easier for distributions with unchanged user space
to support suspend-to-idle as the default system suspend method, some
issues are fixed in the PM core, the latency tolerance PM QoS
framework is improved a bit, the Intel RAPL power capping driver is
cleaned up and there are some fixes and cleanups in the devfreq
subsystem

x86/smpboot: Make logical package management more robust
The logical package management has several issues:
- The APIC ids provided by ACPI are not required to be the same as the
initial APIC id which can be retrieved by CPUID. The APIC ids provided
by ACPI are those which are written by the BIOS into the APIC. The
initial id is set by hardware and can not be changed. The hardware
provided ids contain the real hardware package information.
Especially AMD sets the effective APIC id different from the hardware id
as they need to reserve space for the IOAPIC ids starting at id 0.
As a consequence those machines trigger the currently active firmware
bug printouts in dmesg, These are obviously wrong.
- Virtual machines have their own interesting of enumerating APICs and
packages which are not reliably covered by the current implementation.
The sizing of the mapping array has been tweaked to be generously large to
handle systems which provide a wrong core count when HT is disabled so the
whole magic which checks for space in the physical hotplug case is not
needed anymore.
Simplify the whole machinery and do the mapping when the CPU starts and the
CPUID derived physical package information is available. This solves the
observed problems on AMD machines and works for the virtualization issues
as well.
Remove the extra call from XEN cpu bringup code as it is not longer
required.
Fixes:

These are the documentation changes for 4.10.
It's another busy cycle for the docs tree, as the sphinx conversion
continues. Highlights include:
- Further work on PDF output, which remains a bit of a pain but should be
more solid now.
- Five more DocBook template files converted to Sphinx. Only 27 to go...
Lots of plain-text files have also been converted and integrated.
- Images in binary formats have been replaced with more source-friendly
versions.
- Various bits of organizational work, including the renaming of various
files discussed at the kernel summit.
- New documentation for the device_link mechanism.
...and, of course, lots of typo fixes and small updates.

Pull smp hotplug updates from Thomas Gleixner: "This is the final round of converting the notifier mess to the state machine. The removal of the notifiers and the related infrastructure will happen around rc1, as there are conversions outstanding in other trees.

The new mechanism allows to test almost every hotplug step standalone, so usage sites can exercise all transitions extensively.

x86/ldt: use vfree_atomic() to free ldt entries
vfree() is going to use sleeping lock. free_ldt_struct() may be called with disabled preemption, therefore we must use vfree_atomic() here.

Merge branch 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 microcode update from Ingo Molnar:
"The biggest change (by Borislav Petkov) is a thorough rewrite of the
Intel microcode loader and its interactions with the core code.
The biggest conceptual change is the decoupling of the microcode
loading on boot and application processors (which load the microcode
in different scenarios), so that both parse the input patches with as
few assumptions as possible - this also fixes various kernel address
space randomization bugs. (The AP side then goes on and caches the
result to improve boot performance.)
Since the AMD side already did this, this change also opened up the
path towards more unification/simplification of the core microcode
loading infrastructure:

Pull x86 idle updates from Ingo Molnar:
"There were two bigger changes in this development cycle:
- remove idle notifiers:
32 files changed, 74 insertions(+), 803 deletions(-)
These notifiers were of questionable value and the main usecase,
the i7300 driver, was essentially unmaintained and can be removed,
plus modern power management concepts don't need the callback - so
use this golden opportunity and get rid of this opaque and fragile
callback from a latency sensitive code path.

polling in the idle loop (Borisla Petkov, Thomas Gleixner)"
