[PATCH v2 2/6] KVM: x86: Drop the "EX" part of "EXREG" to avoid collision with APX

Sean Christopherson
2026-04-09T22:42:51Z

Now that NR_VCPU_REGS is no longer a thing, and now that now that RIP is
effectively an EXREG, drop the "EX" is for extended (or maybe extra?")
prefix from non-GPR registers to avoid a collision with APX (Advanced
Performance Extensions), which adds:

16 additional general-purpose registers (GPRs) R16–R31, also referred
to as Extended GPRs (EGPRs) in this document;

I.e. KVM's version of "extended" won't match with APX's definition.

No functional change intended.
