Ian Munsie 4c6d9acce1 powerpc/mm: Add hooks for cxl ... This adds hooks into the core powerpc mm code for cxl. The core powerpc code sometimes uses local tlbie. Unfortunately this won't work with the current cxl driver as it relies on snooping tlbie broadcasts. The cxl hardware can have TLB entries invalidated via MMIO but this is not currently supported by the driver. In future we can make local tlbie smarter so that it invalidates cxl contexts via MMIO when it needs to but for now we have this workaround. This workaround checks for any active cxl contexts and if so, disables local tlbie. This also adds a hook for when SLBs are invalidated. This ensures any corresponding SLBs in cxl are also invalidated at the same time. This is required for segment demotion.
