Patch 1 refreshes the boot-stage register before the fallback state check. Patch 2 distinguishes S0ix from S3/S4 and routes thaw through a normal D0 transition. Patch 3 verifies the state after GP0 and completes any missing RX or mailbox setup. It also serializes the alive-context claim between the GP0 handler and the PM fallback so only one path reinitializes the RX ring. Patch 4 clears the GP0 cause with a direct W1C write.
