cc83a2c614 Don't use memcmp() and memcpy() on userspace addresses. 
Pointed out by mrg@, thanks.

This also makes it so a malicious root user can't panic the kernel by
passing junk pointers.

eddfaaf54c Move i386/amd64 common code (check_pa_acc()) to x86. 
I didn't know what header to put the prototype in, so it's both in
i386/mem.c and amd64/mem.c; probably can be moved later.

Tested on amd64, assumed working on i386. :)

yamt@ okay

048a21b75e Simplify and rework duplication check code. 
If we already have an entry, we only print a message mentioning it if the
fingerprints mismatch; that may indicate a security issue.

If the fingerprints match, there's a good chance it's the same file
appearing multiple times as a hard-link, in which case print a message
only if the verbose level is 1 or more.

1aeaeb0efa When setting the FIFO preload, chose an entirely safe value rather than 
using a completely bogus heuristic to guess at one.  This might cause FIFO
underruns in particularly exciting video modes, but it also makes more
boring ones work correctly.

40d6264cec Remove bogus sanity check. 
The passed size doesn't mean anything really and can only help detect
corrupted configuration files, which should be done in userland anyway.

Note it's possible to trigger a kernel panic by passing a junk
pointer in the 'fingerprint' member of the parameters, but then again
that's true for anything that copies in data from a userland-supplied
pointer. And we have plenty of those.

At the moment, Veriexec only allows the super-user to open the pseudo
device, so it's ~okay. Maybe we should address that in copy(9) or
something?

8b52dc54b3 Implement another class of `unit not ready' sense handling that is not 
fatal.. A `long write in progress' is a retry again later command that is
issued when a device returns immediately after a write request but needs
some time before it can handle read requests.

Those older versions of gcc don't eliminate unused functions/vars
anyway, so it's enough just to suppress the warning.
