xtensa: mmu: invalidate mem domain TLBs during page table swap This adds a kconfig to enable invalidating the TLBs related to the incoming thread's memory domain during page table swaps. It provides a workaround, if needed, to clear out stale TLB entries used by the thread being swapped out. Those stale entries may contain incorrect permissions and rings.
