Anyone working on the KPTI support for powerpc?

I assume some of the powerpc platforms would be impacted by the newly announced meltdown/spetre vulnerabilities. It will be good if we have an aligned implementation of the KPTI. Regards, Leo

[PATCH] powerpc: cell: use irq_of_parse_and_map helper

[PATCH 0/3] PCI: move DT PCI functions to PCI core

Most subsystem specific functions have been moved into the respective subsystems. Only PCI and networking remain. This series moves most of the PCI related code to drivers/pci/of.c. Some bus address functions for PCI remain in of/address.c because we don't have infrastructure to split up the per

Instead of calling both of_irq_parse_pci and irq_create_of_mapping, call of_irq_parse_and_map_pci instead which does the same thing. This will allow making of_irq_parse_pci a private, static function. This changes the logic slightly in that the fallback path will also be taken if
