We support various non-Intel CPUs that don't have the CPUID
instruction, so the M486 test was wrong. For now, fix it with a big
hammer: handle missing CPUID on all 32-bit CPUs.

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.

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).
Use native_cpuid() instead which is an asm wrapper for the CPUID
instruction.

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.

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"

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.

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.

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.

These files were only including module.h for exception table
related functions. 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.

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.

"Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for

- Prevent kernel execution of userspace on P9 Radix (similar to

- 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.

introduced, the debug logs are overhauled and a set of tracepoints is
added.
Then there are several patches in regard to inline assemblies. One
compile fix and several missing memory clobbers. As far as we can tell
the omitted memory clobbers have not caused any breakage.
A small change to the PCI arch code, the machine can tells us how big
the function measurement blocks are. The PCI function measurement will
be disabled for a device if the queried length is larger than the
allocated size for these blocks.
And two more patches to correct five printk messages.

Pull ARM SoC platform updates from Arnd Bergmann:
"These are updates for platform specific code on 32-bit ARM machines,
essentially anything that can not (yet) be expressed using DT files.
Noteworthy changes include:
- Added support for the TI DRA71x family of SoCs in mach-omap2, this
is an new variant of the the DRA72x/DRA74x automotive infotainment
chips we already supported for a while.
- Added support for the ST STM32F746 SoC, the first Cortex-M7 based
microcontroller we support, related to the smaller STM32F4 family.
- Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see
http://elinux.org/RZ-G
- SMP is now supported on the OX820 platform
- A lot of code in mach-omap2 gets removed as a follow-up to removing
support for board files in the previous release
- Davinci has some new work to improve USB support
- For i.MX, the performance monitor now supports profiling the memory
controller using 'perf'"

Pull ARM SoC non-urgent fixes from Arnd Bergmann:
"As usual, we queue up a few fixes that don't seem urgent enough to go
in through -rc, or that just came a little too late given their size.
The zx fixes make the platform finally boot on real hardware, the
davinci and imx31 get the DT support working better for some of the
machines that are still normally used with classic board files. One
tegra fix is important for new bootloader versions, but the bug has
been around for a while without anyone noticing.
The other changes are mostly cosmetic"
