Summary
x86/kexec: Fix bug with call depth tracking
Details

In the Linux kernel, the following vulnerability has been resolved:

x86/kexec: Fix bug with call depth tracking

The call to ccplatformhas() triggers a fault and system crash if call depth tracking is active because the GS segment has been reset by loadsegments() and GSBASE is now 0 but call depth tracking uses per-CPU variables to operate.

Call ccplatformhas() earlier in the function when GS is still valid.
