x86/debug: Include percpu.h in debugreg.h to get DECLARE_PER_CPU() et al
Include percpu.h to pick up the definition of DECLARE_PER_CPU() and friends instead of relying on the parent to provide the #include. E.g. swapping the order of includes in arch/x86/kvm/vmx/nested.c (simulating KVM code movement being done for other purposes) results in build errors: In file included from arch/x86/kvm/vmx/nested.c:3: arch/x86/include/asm/debugreg.h:9:32: error: unknown type name âcpu_dr7â=99 9 | DECLARE_PER_CPU(unsigned long, cpu_dr7); | ^~~~~~~ Signed-off-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20221110201707.1976032-1-seanjc@google.com
