Virtual memory map to accomodate 64 MB SPI flash We use a 64 MB SPI NOR flash on Prowl which the SPI flash driver ioremaps() *twice* into the vmalloc area. As a result, we needed to increase the size of the vmalloc area from 64MB to 256MB. The existing virtual memory layout did not accommodate this change. We had to tweak it a little. Note that TASK_UNMAPPED_BASE needs to be a multiple of PAGE_SIZE.
