The commit 2ffd9e33ce4a ("x86/hyper-v: Use hypercall for remote TLB flush") introduced a new C-file where uapi/linux/hyperv.h is included first. This makes build failed since UAPI headers are heavily dependent to special types of variables, e.g. __u8. CC arch/x86/hyperv/mmu.o In file included from include/linux/hyperv.h:28:0, from arch/x86/hyperv/mmu.c:3: include/uapi/linux/hyperv.h:71:2: error: unknown type name ‘__u8’ __u8 operation; ^~~~ Include linux/types.h to the UAPI header like many others do.
