Unlikely in the extreme, I'd have said - there's enough change in the last few years that it would be infeasible. You'd be easier installing from a tarball of 7.3 yourself and then compiling kernel 4.15 for yourself or nagging Patrick and the rest. Maybe you need a Slackware 14.2.1 "Doesn't melt" point release to be made :)

[Although pbonzini suggests that all fixes will be backported to 4.14 as the LTS version above, I suspect that the amount of work will mean that it's only for paying enterprise customers - the kernel fixes are still very much ongoing and some of the ARM64 fixes will only start in 4.16 if I read it correctly?]

Thanks amacater.

Yes, I imagine you're correct.

If I want the Spectre fixes, I'll have to upgrade from Slackware64 14.2 to 15.0 when it is released .

I've never had to do that before -- Slackware since Version 7.0 has always remained Secure and Stable as long as my Hardware lived :)

Odd situation though with Spectre in that it requires both compiler and kernel patches for 'mitigation'.

The 4.4.113+ Kernels are ready but gcc 5.3.0 is not.

Thanks again !

Thanks jfb !

Yes, I've already downloaded and installed the updates on two Slackware64 14.2 Systems

Now I am studying Eric Hameleers( aka Alien Bob )'s multilib gcc and glibc SlackBuilds so I can try to bootstrap multilib versions on my working Laptop some time this weekend.

Thanks again !
