Hi,
This patch series adds a simple test for sysenter instruction running in
comp32 mode, while using Intel vendor ID.
In this setting, KVM emulates this instruction to help with cross-vendor
migration on AMD.
I also added a patch to 'msr' test to run it with Intel's vendor ID, since this
test tests that SYSENTER EIP/ESP msrs are 64 bit wide which is only true on AMD.
KVM used to emulate these msrs to be always 64 bit on AMD, but this soon will
be changed to do the emulation only when guest CPU vendor ID is of Intel.
Best regards,
Maxim Levitsky
