Hi Linus,

Please pull some x86/cpu changes for 7.1-rc1.

The existing Linear Address Space Separation (LASS) support punted on
support for common EFI and vsyscall configs. Complete the
implementation by supporting EFI and vsyscall=xonly.

The last few commits clean up CPUID use in the Intel "avs" sound
driver and update the x86-cpuid-db file.
