[SOLVED] ARM lpc32xx build fails for linux-2.6.34
I am currently upgrading the ARM kernel from Linux 188.8.131.52 to 2.6.34.
I applied all the patches for the lpc32xx, and tried to build.
The build failed with missing __pfn_to_bus and __bus_to_pfn.
A search through the sources showed that "__arch_page_to_dma" definition is not available for the lpc32xx processors.
Is there a patch that provides the above? Is anyone know of a solution for it?
make: `include/generated/mach-types.h' is up to date.
