"This update for spectre-meltdown-checker fixes the following issues :

  - feat: implement TAA detection (CVE-2019-11135
    bsc#1139073)

  - feat: implement MCEPSC / iTLB Multihit detection
    (CVE-2018-12207 bsc#1117665)

  - feat: taa: add TSX_CTRL MSR detection in hardware info

  - feat: fwdb: use both Intel GitHub repo and MCEdb to
    build our firmware version database

  - feat: use --live with --kernel/--config/--map to
    override file detection in live mode

  - enh: rework the vuln logic of MDS with --paranoid (fixes
    #307)

  - enh: explain that Enhanced IBRS is better for
    performance than classic IBRS

  - enh: kernel: autodetect customized arch kernels from
    cmdline

  - enh: kernel decompression: better tolerance against
    missing tools

  - enh: mock: implement reading from /proc/cmdline

  - fix: variant3a: Silvermont CPUs are not vulnerable to
    variant 3a

  - fix: lockdown: detect Red Hat locked down kernels

  - fix: lockdown: detect locked down mode in vanilla 5.4+
    kernels

  - fix: sgx: on locked down kernels, fallback to CPUID bit
    for detection

    cached version is older

  - fix: pteinv: don't check kernel image if not available

  - fix: silence useless error from grep (fixes #322)

  - fix: msr: fix msr module detection under Ubuntu 19.10
