acpi/x86: introduce __apci_map_table, v4
to prevent wrongly overwriting fixmap that still want to use. ACPI used to rely on low mappings being all linearly mapped and grew a habit: it never really unmapped certain kinds of tables after use. This can cause problems - for example the hypothetical case when some spurious access still references it. v2: remove prev_map and prev_size in __apci_map_table v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to early_acpi_os_unmap_memory v4: fix typo in one acpi_get_table_with_size calling Signed-off-by:Yinghai Lu <yhlu.kernel@gmail.com> Acked-by:
