KVM: x86: Partially allow KVM_SET_CPUID{,2} after KVM_RUN

2022-01-27T11:03:04+00:00

commit c6617c61e8fe44b9e9fdfede921f61cac6b5149d upstream.

Commit feb627e8d6f6 ("KVM: x86: Forbid KVM_SET_CPUID{,2} after KVM_RUN")
forbade changing CPUID altogether but unfortunately this is not fully
compatible with existing VMMs. In particular, QEMU reuses vCPU fds for
CPU hotplug after unplug and it calls KVM_SET_CPUID2. Instead of full ban,
check whether the supplied CPUID data is equal to what was previously set.

KVM: x86: Do runtime CPUID update before updating vcpu->arch.cpuid_entries

2022-01-27T11:03:03+00:00

commit ee3a5f9e3d9bf94159f3cc80da542fbe83502dd8 upstream.

kvm_update_cpuid_runtime() mangles CPUID data coming from userspace
VMM after updating 'vcpu->arch.cpuid_entries', this makes it
impossible to compare an update with what was previously
supplied. Introduce __kvm_update_cpuid_runtime() version which can be
used to tweak the input before it goes to 'vcpu->arch.cpuid_entries'
so the upcoming update check can compare tweaked data.

No functional change intended.

arm64: dts: qcom: msm8996: drop not documented adreno properties

riscv: dts: microchip: mpfs: Drop empty chosen node

commit 53ef07326ad0d6ae7fefded22bc53b427d542761 upstream.

It does not make sense to have an (empty) chosen node in an SoC-specific
.dtsi, as chosen is meant for system-specific configuration.
It is already provided in microchip-mpfs-icicle-kit.dts anyway.

RISC-V: defconfigs: Set CONFIG_FB=y, for FB console

2022-01-27T11:02:55+00:00

commit 3d12b634fe8206ea974c6061a3f3eea529ffbc48 upstream.

We have CONFIG_FRAMEBUFFER_CONSOLE=y in the defconfigs, but that depends
on CONFIG_FB so it's not actually getting set.  I'm assuming most users
on real systems want a framebuffer console, so this enables CONFIG_FB to
allow that to take effect.

powerpc/cell: Fix clang -Wimplicit-fallthrough warning

2022-01-27T11:02:53+00:00

commit e89257e28e844f5d1d39081bb901d9f1183a7705 upstream.

Clang warns:

arch/powerpc/platforms/cell/pervasive.c:81:2: error: unannotated fall-through between switch labels
        case SRR1_WAKEEE:
        ^
arch/powerpc/platforms/cell/pervasive.c:81:2: note: insert 'break;' to avoid fall-through
        case SRR1_WAKEEE:
        ^
        break;
1 error generated.

Clang is more pedantic than GCC, which does not warn when failing
through to a case that is just break or return. Clang's version is more
in line with the kernel's own stance in deprecated.rst. Add athe missing
break to silence the warning.
