Subject[PATCH v3] x86: SVM: Use the hardware provided GPA instead of page walk
From
Date
This patch series is taken from SEV RFC series [1]. These patches do not
depend on the SEV feature and can be reviewed and merged on their own.

- Use the hardware provided GPA instead of page walk

Droping the following patches from series since they are already accepted

- Add support for additional SVM NFP error codes
- Add kvm_fast_pio_in support


Changes since v2:
- move String op identifier check into new emulator_is_string_op().
- move gpa_available check in emulator_read_write_onepage().

Changes since v1:
- remove redundant gpa_avail check
