Subject: KVM: PPC: Book3S PR: Fix compilation without CONFIG_ALTIVEC
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f24817716efe52f3c8fc137c6893963a0416f3cb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

KVM: PPC: Book3S PR: Fix compilation without CONFIG_ALTIVEC

Commit 9d1ffdd8f3 ("KVM: PPC: Book3S PR: Don't corrupt guest state
when kernel uses VMX") added a call to kvmppc_load_up_altivec() that
isn't guarded by CONFIG_ALTIVEC, causing a link failure when building
a kernel without CONFIG_ALTIVEC set.  This adds an #ifdef to fix this.
