Add new version of Snowridge CPU model that removes MPX feature. MPX support is being phased out by Intel. GCC has dropped it, Linux kernel and KVM are also going to do that in the future.

|

|
|
Add new version of Snowridge CPU model that removes MPX feature.
|
|
|
|
MPX support is being phased out by Intel. GCC has dropped it, Linux kernel
|
|
and KVM are also going to do that in the future.
