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 (impacts MSR writes)
fix: lockdown: detect locked down mode in vanilla 5.4+ kernels
fix: sgx: on locked down kernels, fallback to CPUID bit for detection
fix: fwdb: builtin version takes precedence if the local 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 (fixes #316)
fix: mocking value for read_msr
chore: rename mcedb cmdline parameters to fwdb, and change db version scheme
chore: fwdb: update to v130.20191104+i20191027
chore: add GitHub check workflow
