[PATCH v5 02/14] efi: use early_memremap and early_memunmap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In arch/x86/platform/efi/efi.c and drivers/firmware/efi/efi.c turn to use
early_memremap/early_memunmap instead of early_ioremap/early_iounmap so sparse
will be happy.
