Hi All,
I found out the previous booting issue which caused by
5ea5306c3235a1
arm64: alternatives: apply boot time fixups via the linear mapping
After picked up this commit both hikey and qemu booted well, w and w/o kvm mode.
but kernelci.org didn't give me result yet from yesterday. Anyway it should
be fine to send out fore review.
The draft version backport is
git://git.linaro.org/kernel/linux-linaro-stable.git lts-v4.9-kpti
The backport based on arm tree:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?h=kpti
The following commit aren't included for couple reasons:
a, bpf patch included in LTS; b falkor isn't supported in LTS
c, PAN isn't supported on LTS;
bpf: prevent out-of-bounds speculation
arm64: Implement branch predictor hardening for Falkor
arm64: kpti: Fix the interaction between ASID switching and software PAN
arm64: mm: Introduce TTBR_ASID_MASK for getting at the ASID in the TTBR
perf: arm_spe: Fail device probe when arm64_kernel_unmapped_at_el0()
arm64: erratum: Work around Falkor erratum #E1003 in trampoline code
arm64: mm: Fix and re-enable ARM64_SW_TTBR0_PAN
arm64: mm: Rename post_ttbr0_update_workaround
arm64: mm: Remove pre_ttbr0_update_workaround for Falkor erratum #E1003
arm64: mm: Temporarily disable ARM64_SW_TTBR0_PAN
Any comments are appreciated!

Alex

Hi All,
I pushed a draft version of backport to
git://git.linaro.org/kernel/linux-linaro-stable.git lts-v4.9-kpti
The backport based on arm tree:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?h=kpti
The following commit aren't included for couple reasons:
a, bpf patch included in LTS; b falkor isn't supported in LTS
c, PAN isn't supported on LTS;
bpf: prevent out-of-bounds speculation
arm64: Implement branch predictor hardening for Falkor
arm64: kpti: Fix the interaction between ASID switching and software PAN
arm64: mm: Introduce TTBR_ASID_MASK for getting at the ASID in the TTBR
perf: arm_spe: Fail device probe when arm64_kernel_unmapped_at_el0()
arm64: erratum: Work around Falkor erratum #E1003 in trampoline code
arm64: mm: Fix and re-enable ARM64_SW_TTBR0_PAN
arm64: mm: Rename post_ttbr0_update_workaround
arm64: mm: Remove pre_ttbr0_update_workaround for Falkor erratum #E1003
arm64: mm: Temporarily disable ARM64_SW_TTBR0_PAN
The kernelci testing show it can boot on 82 boards but failed on 12 boards
on latest commit c9966001e6cac2e7c9f8
https://kernelci.org/boot/all/job/lsk/branch/linux-linaro-lsk-v4.9-test/ker…
Debug show the failure is due to __bp_harden_hyp_vecs_start isn't mapped
during booting. So guess I missed some commits from arch/arm/kvm/arm.c to
virt/kvm/arm/arm.c when doing pick up:
d00aff63b0b arm64: KVM: Use per-CPU vector when BP hardening is enabled
Any hints are appreciated!
kvm_arch_init -> init_hyp_mode(conditionally)
->kvm_map_vectors -> create_hyp_mappings(__bp_harden_hyp_vecs_start)
Regards
Alex
