The 35b3fde620 ("KVM: s390: wire up bpb feature") was noticed by the
perf build process:
Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/kvm.h' differs from latest version at 'arch/s390/include/uapi/asm/kvm.h'
The changes in this cset don't cause or require changes in tools/perf/,
so just update the copy to silence the build warning.

There were two trivial updates to these upstream UAPI headers:
arch/s390/include/uapi/asm/kvm.h
arch/s390/include/uapi/asm/kvm_perf.h
arch/x86/lib/x86-opcode-map.txt
Synchronize them with their tooling copies.
(The x86 opcode map includes a new instruction pattern now.)

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.

Time for a sync with ABI/uapi headers with the upcoming v4.14 kernel.
None of the ABI changes require any source code level changes to our
existing in-kernel tooling code:
- tools/arch/s390/include/uapi/asm/kvm.h:
New KVM_S390_VM_TOD_EXT ABI, not used by in-kernel tooling.
- tools/arch/x86/include/asm/cpufeatures.h:
tools/arch/x86/include/asm/disabled-features.h:
New PCID, SME and VGIF x86 CPU feature bits defined.
- tools/include/asm-generic/hugetlb_encode.h:
tools/include/uapi/asm-generic/mman-common.h:
tools/include/uapi/linux/mman.h:
Two new madvise() flags, plus a hugetlb system call mmap flags
restructuring/extension changes.
- tools/include/uapi/drm/drm.h:
tools/include/uapi/drm/i915_drm.h:
New drm_syncobj_create flags definitions, new drm_syncobj_wait
and drm_syncobj_array ABIs. DRM_I915_PERF_* calls and a new
I915_PARAM_HAS_EXEC_FENCE_ARRAY ABI for the Intel driver.
- tools/include/uapi/linux/bpf.h:
New bpf_sock fields (::mark and ::priority), new XDP_REDIRECT
action, new kvm_ppc_smmu_info fields (::data_keys, instr_keys)

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.

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.

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.
