[PATCH v2 1/5] ACPI: table upgrade: use cacheable map for tables

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

 



The new memory allocated in acpi_table_initrd_init() is used to
copy the upgraded tables to it.  So it should be mapped with
early_memunmap() instead of early_ioremap().

This is critical for ARM.
