Sean Christopherson 689ceaad94 KVM: x86: Restore all 64 bits of DR6 and DR7 during RSM on x86-64 ... [ Upstream commit 2644312052d54e2e7543c7d186899a36ed22f0bf ] Restore the full 64-bit values of DR6 and DR7 when emulating RSM on x86-64, as defined by both Intel's SDM and AMD's APM. Note, bits 63:32 of DR6 and DR7 are reserved, so this is a glorified nop unless the SMM handler is poking into SMRAM, which it most definitely shouldn't be doing since both Intel and AMD list the DR6 and DR7 fields as read-only.
