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,
