Looks like I'm missing a one or two definitions in the new headers, and the names have changed slightly in couple of cases. I'll do some more thorough checking and have it all fixed for v2. I didn't know about this allmodconfig target, that will make it a bit easier! Nuno

This improves the situation slightly by associating the #define with asm/mshyperv.h. I'll consider it for v2, thanks! Nuno

To move toward importing headers from Hyper-V directly, switch to using hvhdk.h in all Hyper-V code. KVM code that uses Hyper-V definitions from hyperv-tlfs.h remains untouched. Add HYPERV_NONTLFS_HEADERS everywhere mshyperv.h, asm/svm.h, clocksource/hyperv_timer.h is included in Hyper-V code. Replace hyperv-tlfs.h with hvhdk.h directly in linux/hyperv.h, and define HYPERV_NONTLFS_HEADERS there, since it is only used in Hyper-V device code. Update a couple of definitions to updated names found in the new headers: HV_EXT_MEM_HEAT_HINT, HV_SUBNODE_TYPE_ANY.
