ACPI / PM: Call suspend_nvs_free() earlier during resume
It turns out that some device drivers map pages from the ACPI NVS region during resume using ioremap(), which conflicts with ioremap_cache() used for mapping those pages by the NVS save/restore code in nvs.c. Make the NVS pages mapped by the code in nvs.c be unmapped before device drivers' resume routines run. Signed-off-by: Rafael J.
