Subject[patch 0/2] sysfs/cpu: Implement generic vulnerabilites directory
The meltdown/spectre vulnerabilities affect several architectures and
people are asking for a common way to figure out whether a system is
affected or not.

Create

/sys/devices/system/cpu/vulnerabilites

and the files

/sys/devices/system/cpu/vulnerabilites/meltdown
/sys/devices/system/cpu/vulnerabilites/spectre_v1
/sys/devices/system/cpu/vulnerabilites/spectre_v2

Add the x86 implementation which shows:

meltdown Mitigation: PTI
spectre_v1 Vulnerable
sepctre_v1 Vulnerable

On an AMD CPU the output of meltdown is: Not affected.

If PTI is turned off and the CPU is affected of meltdown the output
becomes: Vulnerable

That series applies on top of

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/pti

Thanks,

tglx
