Man, 2.6.15 is like 2-3 years old....

Due to cache coherence bugs, Fuse has an extra call to work around it;

But my kernel (2.6.15 for mips 4KEc Tangox board) does not have a flush_cache_page().

If I use kangox_flush_all() Fuse works rather well, but the performance is abysmal. Can I simulate this call using one of the calls I do have;

__flush_dcache_page
flush_data_cache_page
tangox_flush_cache_all
cache_flush
kc_flush_cache

Or alternatively, does anyone have the source for flush_cache_page() for said CPU?
