5c571bacc6 enh: CVE-2022-40982 (Downfall) overhaul 
built from commit e7fa2f30cc
 dated 2026-04-02 19:55:25 +0200
 by Stéphane Lesimple (speed47_github@speed47.net)

 - added `--kernel-config` support for all three Kconfig variants seen over all kernel versions up to now
- added `--kernel-map` support for `gds_select_mitigation` in `System.map`
- fixed the `--sysfs-only` mode
- added verbose information about remediation when `--explain` is used
- implemented `--paranoid mode`, requiring `GDS_MITIGATION_LOCKED` so that mitigation can't be disabled at runtime
- fixed offline mode (was wrongly looking at the system `dmesg`)
- better microcode status reporting (enabled, disabled, unsupported, unknown)
- fixed unknown (EOL) AVX-capable Intel family 6 CPUs now defaulting to affected
- fixed 2 missing known affected CPU models: INTEL_FAM6_SKYLAKE_L and INTEL_FAM6_SKYLAKE
- fixed case when we're running in a VM and the hypervisor doesn't let us read the MSR

a20641fbad fix: handle non-numeric ARM CPU architecture values 
Some old ARM processors (e.g., ARM926EJ-S) report CPU architecture
with suffix in /proc/cpuinfo (e.g., "5TEJ" for ARMv5TEJ).

This caused an "integer expression expected" error when comparing
against numeric values. Extract the numeric prefix before integer comparisons.

Fixes #505.

8e33a1dbf2 fix: set cpu_* vars to a default value 
On ARM64 systems, /proc/cpuinfo uses different field names (CPU implementer,
CPU variant, CPU part, CPU revision) instead of x86-style fields (cpu family,
model, stepping). This left these variables empty, causing printf to fail
with 'invalid number' errors when formatting them as hex values.

Fixes #520.

bae43d8370 Replace head -1 by head -n1 
The info page of GNU head says:

> For compatibility 'head' also supports an obsolete option syntax
> '-[NUM][bkm][cqv]', [...] Scripts intended for standard hosts should use
> '-c NUM' or '-n NUM' instead.

At least busybox's head does not support the `-NUM` syntax.
