So now that I've looked at the branch, I think I'll apply these three:
cb88ae619b4c: x86/mm/64: Initialize CR4.PCIDE early 6ec68017784f: x86/hibernate/64: Mask off CR3's PCID bits in the saved CR3 5d1298206d7b: x86/mm: Get rid of VM_BUG_ON in switch_tlb_irqs_off()
The first one is that likely fixed the crash that Sai Praneeth Prakhya reported.
Thanks,
Ingo
