To pick the changes from:
1b07304c58 ("KVM: nVMX: support descriptor table exits")
That adds entries to VMX_EXIT_REASONS, that is used by
tools/perf/arch/x86/util/kvm-stat.c.
This also picks the changes in:
1dc35dacc1 ("KVM: nVMX: check host CR3 on vmentry and vmexit")
But these are not used in 'perf kvm stat', do it just to silence the
kernel/tools file cache coherency detector:
$ make -C tools/perf
make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build

Some mmap related macros have different values for different
architectures. This patch introduces uapi mman.h for each
architectures.
Three headers are cloned from kernel include to tools/include:
tools/include/uapi/asm-generic/mman-common.h
tools/include/uapi/asm-generic/mman.h
tools/include/uapi/linux/mman.h
The main part of this patch is generated by following script:
macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'`
for arch in `ls tools/arch`
do
[ -d tools/arch/$arch/include/uapi/asm ] || mkdir -p tools/arch/$arch/include/uapi/asm
src=arch/$arch/include/uapi/asm/mman.h
target=tools/arch/$arch/include/uapi/asm/mman.h
guard="TOOLS_ARCH_"`echo $arch | awk '{print toupper($0)}'`_UAPI_ASM_MMAN_FIX_H
echo '#ifndef '$guard > $target
echo '#define '$guard >> $target
[ -f $src ] &&
for m in $macros
do
if grep '#define[ \t]*'$m $src > /dev/null 2>&1
then
grep -h '#define[ \t]*'$m $src | sed 's/[ \t]*\/\*.*$//g' >> $target
fi
done
if [ -f $src ]
then
grep '#include <asm-generic' $src >> $target
else
echo "#include <asm-generic/mman.h>" >> $target
fi
echo '#endif' >> $target
echo "$target"
done
exit 0

[ Added new files to tools/perf/MANIFEST to fix the detached tarball build, add mman.h for ARC ]
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
There were changes related to the deprecation of the "pcommit"
instruction:
fd1d961dd6 ("x86/insn: remove pcommit")
dfa169bbee ("Revert "KVM: x86: add pcommit support"")
No need to update anything in the tools, as "pcommit" wasn't being
listed on the VMX_EXIT_REASONS in the tools/perf/arch/x86/util/kvm-stat.c
file.
Just grab fresh copies of these files to silence the file cache
coherency detector:
$ make -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build

We use it in bitops/__ffs.h and bitops/atomic.h, that we also got from
the kernel, but were getting it from either newer systems that carry it
in /usr/include, or from the kernel sources, that we decided not to
touch from tools/ code. Fix it.

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.

To allow the build to complete on older systems, where those files are
either not uptodate, lacking some recent additions or not present at
all.
And check if the copy drifts from the kernel.
