SubjectRe: Compaq Alpha: missing i-cache invalidates in ptrace (2.2.18, 2.4.0) ?

It looks as if there's a very suitable fix in kernel/ptrace.c .

In access_one_page we have

if (write) {
maddr = kmap(page);
memcpy(maddr + (addr & ~PAGE_MASK), buf, len);
flush_page_to_ram(page);
flush_icache_page(vma, page);
kunmap(page);
}

which looks ideal to me...

That still leaves 2.2 broken, though :-(
