Message-ID: <lsq.1407170911.275906277@decadent.org.uk> Date: Mon, 04 Aug 2014 17:48:31 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Paolo Bonzini" <pbonzini@...hat.com>, "Nadav Amit" <namit@...technion.ac.il> Subject: [PATCH 3.2 04/94] KVM: x86: Increase the number of fixed MTRR regs to 10 3.2.62-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Nadav Amit <namit@...technion.ac.il> commit 682367c494869008eb89ef733f196e99415ae862 upstream. Recent Intel CPUs have 10 variable range MTRRs. Since operating systems sometime make assumptions on CPUs while they ignore capability MSRs, it is better for KVM to be consistent with recent CPUs. Reporting more MTRRs than actually supported has no functional implications.
