ata: sata_mv:- Handle return value of devm_ioremap.
Here, If devm_ioremap will fail. It will return NULL. Then hpriv->base = NULL - 0x20000; Kernel can run into a NULL-pointer dereference. This error check will avoid NULL pointer dereference.

efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
