From: Timur Tabi Date: Thu, 17 May 2012 19:10:27 +0000 (-0500) Subject: drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS] X-Git-Tag: v3.8-rc1~68^2~3^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9655aa6b8034ebb69724dc4b54ad4f64a53096d1;p=profile%2Fivi%2Fkernel-x86-ivi.git drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS] The MSR[GS] bit indicates whether the kernel is running in processor guest state mode, but such a check is unnecessary. The driver already checks for the /hypervisor node and the fsl,hv-version property, so it already knows that it's running under the Freescale hypervisor. There is nothing in the driver that inherently requires guest state, anyway. This fixes a break that can occur in some randconfig builds.
