From: Paul Mackerras Date: Mon, 26 May 2014 09:48:35 +0000 (+1000) Subject: KVM: PPC: Book3S: Move KVM_REG_PPC_WORT to an unused register number X-Git-Tag: v5.15~17469^2~11^2~1^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1d8a96daf641aea11c25268eab678a76215541a;p=platform%2Fkernel%2Flinux-starfive.git KVM: PPC: Book3S: Move KVM_REG_PPC_WORT to an unused register number Commit b005255e12a3 ("KVM: PPC: Book3S HV: Context-switch new POWER8 SPRs") added a definition of KVM_REG_PPC_WORT with the same register number as the existing KVM_REG_PPC_VRSAVE (though in fact the definitions are not identical because of the different register sizes.) For clarity, this moves KVM_REG_PPC_WORT to the next unused number, and also adds it to api.txt.
