devices which doesn't need pinning of pages for DMA anymore. Add support for the command submission to devices using new x86 instructions like ENQCMD{,S} and MOVDIR64B. In addition, add support for process address space identifiers (PASIDs) which are referenced by those command submission instructions along with the handling of the PASID state on context switch as another extended state. Work by Fenghua Yu, Ashok Raj, Yu-cheng Yu and Dave Jiang. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAl996DIACgkQEsHwGGHe VUqM4A/+JDI3GxNyMyBpJR0nQ2vs23ru1o3OxvxhYtcacZ0cNwkaO7g3TLQxH+LZ k1QtvEd4jqI6BXV4de+HdZFDcqzikJf0KHnUflLTx956/Eop5rtxzMWVo69ZmYs8 QrW0mLhyh8eq19cOHbQBb4M/HFc1DXBw+l7Ft3MeA1divOVESRB/uNxjA25K4PvV y+pipyUxqKSNhmBFf2bV8OVZloJiEtg3H6XudP0g/rZgjYe3qWxa+2iv6D08yBNe g7NpMDMql2uo1bcFON7se2oF34poAi49BfiIQb5G4m9pnPyvVEMOCijxCx2FHYyF nukyxt8g3Uq+UJYoolLNoWijL1jgBWeTBg1uuwsQOqWSARJx8nr859z0GfGyk2RP GNoYE4rrWBUMEqWk4xeiPPgRDzY0cgcGh0AeuWqNhgBfbbZeGL0t0m5kfytk5i1s W0YfRbz+T8+iYbgVfE/Zpthc7rH7iLL7/m34JC13+pzhPVTT32ECLJov2Ac8Tt15 X+fOe6kmlDZa4GIhKRzUoR2aEyLpjufZ+ug50hznBQjGrQfcx7zFqRAU4sJx0Yyz rxUOJNZZlyJpkyXzc12xUvShaZvTcYenHGpxXl8TU3iMbY2otxk1Xdza8pc1LGQ/ qneYgILgKa+hSBzKhXCPAAgSYtPlvQrRizArS8Y0k/9rYaKCfBU= =K9X4 -----END PGP SIGNATURE----- Merge tag 'x86_pasid_for_5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 PASID updates from Borislav Petkov: "Initial support for sharing virtual addresses between the CPU and devices which doesn't need pinning of pages for DMA anymore.
