Now the generic code can handle kallsyms fixup properly so no need to
keep the arch-functions anymore.

Now arch-specific functions all do the same thing. When it fixes the
symbol address it needs to check the boundary between the kernel image
and modules. For the last symbol in the previous region, it cannot
know the exact size as it's discarded already. Thus it just uses a
small page size (4096)
The symbol fixup is necessary for symbols in kallsyms since they don't
have size info. So we use the next symbol's address to calculate the
size. Now it's also used for user binaries because sometimes they
miss size for hand-written asm functions.
There's a arch-specific function to handle kalls

Only alpha, ia64, powerpc, and sh define SLOW_DOWN_IO, and there are no

themselves unused. Remove them all.

To avoid bugs and speculative execution exploits due to type-confused
pointers at the end of a list_for_each_entry() loop, one measure is to
restrict code to not use the iterator variable outside the loop block.

When passed a non-head list element, list_add_tail() actually adds the
new element to its left, which is what we want. Despite the slightly
confusing name, use the dedicated function which does the same thing as
the open-coded list_add(pos->prev).
