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 :-(
