add SPDX GPL-3.0 license identifier
...
The spectre-meltdown-checker.sh file is missing licensing information.
The SPDX identifier is a legally binding shorthand, which can be
used instead of the full boiler plate text.

...
* Cortex A8 Vulnerable
Arm Cortex A8 is vulnerable to variants 1 & 2 (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability )
Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register )
False negative reported by @V10lator in #206
* ARM Cortex A12 Vulnerable to 1&2
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability
* A76 vulnerable to variant 4
All arch 8 cortex A57-A76 are vulnerable to variant 4.
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability
* Whitelist variant4 nonvuln Arms
* ARM Cortex Whitelist & Cumulative Blacklist
Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability ).
Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.

* variant4 from common.c::cpu_no_spec_store_bypass
Variant 4 - Add function to 'whitelist' the hand-full of CPUs unaffected by speculative store bypass.
This would allow improved determination of variant 4 status ( #189 ) of immune CPUs while waiting for the 4.17/stable patches to be backported to distro kernels.
Source of cpu list : https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/kernel/cpu/common.c#n945 )
Modeled after is_cpu_specex_free()
* amd families fix
amd families are reported by parse_cpu_details() in decimal
* remove duplicates
Only list processors which speculate and are immune to variant 4.
Avoids duplication with non-speculating CPUs listed in is_cpu_specex_free()
