-Subject: [PATCH] arm: bcm2835: Fix FIQ early ioremap
-
-The ioremapping creates mappings within the vmalloc area. The
-equivalent early function, create_mapping, now checks that the
-requested explicit virtual address is between VMALLOC_START and
-VMALLOC_END. As there is no reason to have any correlation between
-the physical and virtual addresses, put the required mappings at
-VMALLOC_START and above.
