Pull arm64 spectre fixes from James Morse: "ARM64 Spectre-BHB mitigations: - Make EL1 vectors per-cpu - Add mitigation sequences to the EL1 and EL2 vectors on vulnerble CPUs - Implement ARCH_WORKAROUND_3 for KVM guests - Report Vulnerable when unprivileged eBPF is enabled" * tag 'arm64-spectre-bhb-for-v5.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: proton-pack: Include unprivileged eBPF status in Spectre v2 mitigation reporting arm64: Use the clearbhb instruction in mitigations KVM: arm64: Allow SMCCC_ARCH_WORKAROUND_3 to be discovered and migrated arm64: Mitigate spectre style branch history side channels arm64: proton-pack: Report Spectre-BHB vulnerabilities as part of Spectre-v2 arm64: Add percpu vectors for EL1 arm64: entry: Add macro for reading symbol addresses from the trampoline arm64: entry: Add vectors that have the bhb mitigation sequences arm64: entry: Add non-kpti __bp_harden_el1_vectors for mitigations arm64: entry: Allow the trampoline text to occupy multiple pages arm64: entry: Make the kpti trampoline's kpti sequence optional arm64: entry: Move trampoline macros out of ifdef'd section arm64: entry: Don't assume tramp_vectors is the start of the vectors arm64: entry: Allow tramp_alias to access symbols after the 4K boundary arm64: entry: Move the trampoline data page before the text page arm64: entry: Free up another register on kpti's tramp_exit path arm64: entry: Make the trampoline cleanup optional KVM: arm64: Allow indirect vectors to be used without SPECTRE_V3A arm64: spectre: Rename spectre_v4_patch_fw_mitigation_conduit arm64: entry.S: Add ventry overflow sanity checks
