From 09b9ee643f90ef95e30e594df2a3c83ccaf75b1f Mon Sep 17 00:00:00 2001 From: Tao Xu Date: Mon, 29 Oct 2018 16:39:53 +0800 Subject: i386: Add PKU on Skylake-Server CPU model As the release document ref below link (page 13): https://software.intel.com/sites/default/files/managed/c5/15/\ architecture-instruction-set-extensions-programming-reference.pdf PKU is supported in Skylake Server (Only Server) and later, and on Intel(R) Xeon(R) Processor Scalable Family. So PKU is supposed to be in Skylake-Server CPU model. And PKU's CPUID has been exposed to QEMU. But PKU can't be find in Skylake-Server CPU model in the code. So this patch will fix this issue in Skylake-Server CPU model.
