Subject: [PATCH] KVM: arm64: nvhe: Fix build failure with gcc
Date: Tue, 10 Jun 2025 20:41:32 +0530	[thread overview]
Message-ID: <20250610151132.1758206-1-aneesh.kumar@kernel.org> (raw)

Address a build failure encountered with aarch64-linux-gnu-gcc version
13.3.0 (Ubuntu 13.3.0-6ubuntu2~24.04)

/usr/bin/aarch64-linux-gnu-ld: arch/arm64/kvm/hyp/nvhe/kvm_nvhe.o: in function `__clock_mult_uint128':
/linux/work/arch/arm64/kvm/hyp/nvhe/clock.c:27:(.hyp.text+0x120d8): undefined reference to `__kvm_nvhe___lshrti3'
/linux/work/arch/arm64/kvm/hyp/nvhe/clock.c:27:(.hyp.text+0x120d8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `__kvm_nvhe___lshrti3'

Similar to commit 9bfe7553fadb ("arm64: Implement __lshrti3 library function"),
this change use the added helper.
