s/well maintained port/port that linus takes patches from regularly/
What do you want to do about flush_icache_page? You want to change it
to flush_dcache_page at eviction time, and then we can purge that page
from our icache in update_mmu_cache?

You may as well drop this hunk from the diff; our current tree doesn't
even have these functions; just:
static inline void
flush_page_to_ram(struct page *page)
{
}
in asm/cacheflush.h
