The following patch adds support for 256KB PAGE_SIZE on ppc44x-based boards.
The applications to be run on the kernel with 256KB PAGE_SIZE have to be
built using the modified version of binutils, where the MAXPAGESIZE
definition is set to 0x40000 (as opposite to standard 0x10000).
Have you measured the performance using a 64kB page size? If so, how
does it compare with the 256kB page size?
The 64kB page size has the attraction that no binutils changes are
required.
