Using "-W" found a few places that should probably use signed
variables since they can contain (and check for) negative error
values.

While reading code, I found this buglet.  If the TIOCGWINSZ fails,
mconf.c assumes 24/80 as screen size, without honoring the LINES and
COLUMNS environment variables.  This is the shorter and IMHO more
correct version.

mcdx has different IRQ numbers for all drives; irq handler needs a
pointer to structure describing the drive in question.  However, instead
of passing such pointer at request_irq() time and having it passed to
mcdx_intr() for free, mcdx.c sticks the pointer in question into an
array indexed by IRQ number and has mcdx_intr() go look it up there. 

Cleaned up, array killed.

	Trivial annotations + typo fix in _snd_ioctl32_hwdep_dsp_image()
(we want to copy 32bit structure from userland, convert it to native one
and do normal ioctl on it; see the first changed line below for what's
really happening...)

	Missing '=' in C99 initializer

	Usual "inline used before definition" fixes in nsp32.c and sg.c

	Almost all are trivial, aacraid/linit.c annotations had caught a bug -
copy_from_user() where copy_in_user() should've been.

	Extraction of int from pointer is slightly broken in several places.

	Casts from __user to address-space-agnostic in amd64 and i386
made explicit (__force added; in these places we pass userland pointer
to arch-specific code that handles kernel and userland pointers the
same way).
	csum_partial_copy_*() annotated properly

	this basically repeats the stuff done to fs/binfmt_aout.c for amd64
and sparc64 aout32.

	(no, it still doesn't fix sparc32-smp - just partial compile
fixes ;-/)

We have a fun situation with read_descriptor_t - all its instances end
up passed to some actor; these actors use desc->buf as their private
data; there are 5 of them and they expect resp:

        struct lo_read_data *
        struct svc_rqst *
        struct file *
        struct rpc_xprt *
        char __user *

IOW, there is no type safety whatsoever; the field is essentially untyped,
we rely on the fact that actor is chosen by the same code that sets ->buf
and expect it to put something of the right type there.

Right now desc->buf is declared as char __user *.  Moreover, the last
argument of ->sendfile() (what should be stored in ->buf) is void __user *,
even though it's actually _never_ a userland pointer.

If nothing else, ->sendfile() should take void * instead; that alone removes
a bunch of bogus warnings.  I went further and replaced desc->buf with a
union of void * and char __user *.

Rename PCDP_TABLE_GUID back to HCDP_TABLE_GUID to get the file to compile
again.  This change is against current 2.6 BK and is under
CONFIG_IA64_EARLY_PRINTK_UART.

Al's last changes mean that it is now annotated as a user
pointer, and we want to avoid warnings.

	access_ok() expects a pointer, not unsigned long.  It's not a
problem on platforms that have this guy done as a macro (or ones that
do not use fs/compat.c at all), but that's still wrong and on some
platforms that care we actually have access_ok() as inlined function.
Bogus cast removed.

__vfs_follow_link() really should be inline; that's a special case since
we are in the middle of recursion and really want to conserve stack
space.  Moved before the first use, made inline again.

(partially based on patch from Mika Kukkonen)

	Dumb Typo(tm) - the first bug caught by 0/NULL checks (arg is
really a kernel pointer there, so memset() is actually OK - results
will be copied to userland by caller.  Or would be, if we would not
oops  ;-)

	ipc compat code switched to compat_alloc_user_space() and annotated.

	ss_sp in struct sigaltstack made __user
	->si_addr and ->sival_ptr made __user
	your ->sa_restorer and ->sa_handler changes propagated
	users of these guys annotated on i386/amd64/alpha/sparc/sparc64
