For powerpc, s390, x86 and the main uapi linux/kvm.h header, none of
them entail changes in tooling.

Sync KVM ABI additions and x86 CPU features additions - neither of which
has any impact on the tooling build.

Sync the following tooling headers with the latest kernel version:
tools/arch/powerpc/include/uapi/asm/kvm.h
tools/arch/x86/include/asm/cpufeatures.h
tools/include/uapi/drm/i915_drm.h
tools/include/uapi/linux/if_link.h
tools/include/uapi/linux/kvm.h
All the changes are new ABI additions which don't impact their use
in existing tooling.

The changes in the 3214d01f139b ("KVM: PPC: Book3S: Provide information
about hardware/firmware CVE workarounds") commit right now will not
produce any change in the tools, but that is because we still need to
improve tools/perf/trace/beauty/kvm_ioctl.sh to build per arch string
tables, so that we avoid assigning multiple times to the same command
string entry, i.e. multiple defines, for different arches, have the same
value, causing this:
In file included from trace/beauty/ioctl.c:82:0:
/tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c: In function ‘ioctl__scnprintf_kvm_cmd’:
/tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:76:11: error: initialized field overwritten [-Werror=override-init]
/tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:88:11: note: (near initialization for ‘kvm_ioctl_cmds[165]’)
/tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:90:11: error: initialized field overwritten [-Werror=override-init]
[0xa6] = "PPC_GET_SMMU_INFO",
^~~~~~~~~~~~~~~~~~~
So the onlye effect of updating the tools/ copy of ppc's kvm.h header
is to silence these perf build warnings:
Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/kvm.h' differs from latest version at 'arch/powerpc/include/uapi/asm/kvm.h'
At some point we should do what we did for the errno tables and create
per-arch string translation tables for the KVM ioctl commands for the
architectures supporting KVM, such as s/390, PowerPC, x86_64 and ARM.

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

Sync up (copy) the following v4.13 kernel headers to the tooling headers:
arch/arm/include/uapi/asm/kvm.h:
arch/arm64/include/uapi/asm/kvm.h:
arch/powerpc/include/uapi/asm/kvm.h:
arch/s390/include/uapi/asm/kvm.h:
- KVM ABI extensions, which do not affect perf tooling
arch/x86/include/asm/cpufeatures.h:
arch/x86/include/asm/disabled-features.h:
- New PCID CPU feature on Intel CPUs - does not affect tooling.
I.e. no real changes were needed to resolve the build warnings, just a plain copy
of the latest kernel header version.

Sync (copy) the following v4.12 kernel headers to the tooling headers:
arch/x86/include/asm/disabled-features.h:

arch/powerpc/include/uapi/asm/kvm.h:
arch/s390/include/uapi/asm/kvm.h:
arch/arm/include/uapi/asm/kvm.h:
arch/arm64/include/uapi/asm/kvm.h:
- 'struct kvm_sync_regs' got changed in an ABI-incompatible way,
fortunately none of the (in-kernel) tooling relied on it
- new KVM_DEV calls added
arch/x86/include/asm/required-features.h:
- 5-level paging hardware ABI detail added
arch/x86/include/asm/cpufeatures.h:
- new CPU feature added
arch/x86/include/uapi/asm/vmx.h:
- new VMX exit conditions
None of the changes requires fixes in the tooling source code.

The following upstream headers were updated:
- The x86 cpufeatures.h file picked up a couple of new feature entries
- The PowerPC and ARM KVM headers picked up new features
None of which requires changes to perf tooling, so refresh the tooling copy.

Those kernel files were being directly accessed, which we're not
allowing anymore to avoid that changes in the kernel side break tooling.
Warn if these copies drift from the original files.
