Before commit 3efc75ad9d9, the missing file would incorrectly cause stale files to be included in linux-headers/. The files were never committed to qemu.git, but were wrong nevertheless. The build would just use the system version of the files, which is opposite to the idea of importing Linux header files into QEMU's tree. Create forwarding headers, resembling the ones that are generated during a kernel build by scripts/Makefile.asm-generic, if a file is only installed under include/asm-generic/.

charset="utf-8" Right now QEMU is importing arch/x86/include/uapi/asm/kvm_para.h because it includes definitions for kvmclock and for KVM CPUID bits. However, other definitions for KVM hypercall values and return codes are included in include/uapi/linux/kvm_para.h and they will be used by SEV-SNP. To ensure that it is possible to include both and "standard-headers/asm-x86/kvm_para.h" without conflicts, include linux/kvm_para.h as a portable header too, and forward linux-headers/ files to those in include/standard-headers. Note that will include architecture-specific definitions as well, but "standard-headers/linux/kvm_para.h" will not because it can be used in architecture-independent files. This could easily be extended to other architectures, but right now they do not need any symbol in their specific kvm_para.h files.
