[PATCH 1/1 fyi] tools headers x86 svm: Sync svm header with the kernel sources
From: Arnaldo Carvalho de Melo
Date: Wed Mar 04 2026 - 11:14:13 EST
tldr; Just FYI, I'm carrying this on the perf tools tree.
Full explanation:
There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.
See further details at:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/include/uapi/README
To pick the changes in:
d7507a94a0720223 ("KVM: SVM: Treat exit_code as an unsigned 64-bit value through all of KVM")
This time causes no changes in building the tools.
Just addresses this perf build warning:
Warning: Kernel ABI header differences:
diff -u tools/arch/x86/include/uapi/asm/svm.h arch/x86/include/uapi/asm/svm.h
Please see tools/include/uapi/README for further details.
