The __restore_processor_state() fn restores %gs on resume from S3. As such, it cannot be protected by the stack-protector guard since %gs will not be correct on function entry. There are only a few other fns in this file and it should not negatively impact kernel security that they will also have the stack-protector guard rem...

Hi, After some recent merge to Linus tree resume from ram on my thinkpad t400 stopped working. My latest test was done on today Linus git master tree. I'm closing lid, it suspends according to "moon" led. When I open lid I see that LCD backlight is on (not sure if it turns on when I open lid or maybe it never turns off), black screen with cursor blinking in upper corner but...
