Backporting patches that fix TBT at bootup

Backporting patches that fix TBT at bootup

[Mario.Limonciello]

Hi,

During kernel 4.14 some issues were fixed for Thunderbolt enumeration at bootup.  
They were referenced in an issue
(https://github.com/01org/thunderbolt-software-user-space/issues/24#issuecomment-328011428)
There are 3 patches that Mika mentioned would be evaluated to be backported back to 4.13.

As 4.14 has come and gone now, I wanted to see if there was any other thoughts about 
bringing those back to stable now on 4.13 (or did they come back and I just didn't know?)

ecc1165b8b74 ACPICA: Dispatch active GPEs at init time
1312b7e0caca ACPICA: Make it possible to enable runtime GPEs earlier
eb7f43c4adb4 ACPI / scan: Enable GPEs before scanning the namespace

Thanks!

I'm not aware of anything else needed at that point.

Mika, should the three commits above be sufficient?

Thanks,
Rafael

Yup, those should be all that is needed and they are included in
stable v4.13.13.

They are already in stable starting from v4.13.13.
