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

	Missing bits of cpumask_t conversion

	* added usual CHECK assignment in Makefile
	* switched uaccess.h to __check_uptr()
	* added L on long constants (ones missed earlier)
	* added __user in osf_sys.c (duh - I've added __user to cast in
the initializer, but forgot to add it in declaration)

	a) vfc is not 64bit-clean, marked as such in Kconfig
	b) aurora is simply broken - still uses tqueues.  Marked as broken.
	c) vfc does dereferencing of userland pointer, right after having
carefully copied the data to kernel space ;-)  Fixed.
	d) vfc ->mmap() had missed prototype change.  Fixed.
	e) BPP ioctls are misdeclared - they should've been _IO(...) instead
of _IOR(..., void).  Too late to fix, but we can at least make them
_IOR(..., char) - same value, but doesn't try to find sizeof(void).

	tms380tr is used both by ISA and PCI drivers.  Enabling/disabling
DMA is done only for ISA ones (it's protected by if (dev->dma > 0) and
PCI ones leave it 0), but it's compiled unconditionally.  Which breaks
on platforms that don't have that ISA crap at all, but support PCI just
fine.  Code in question placed under ifdef CONFIG_ISA.

bitrot strikes again...

direct write to userland pointer.

	Division by zero is an ugly thing...  We are safe wrt overflows,
since the maximal value we ever pass is 10000 - not enough to overflow
unless you've got a platform with HZ > 200000.

	usb ioctls in compat_ioctl.c switched to compat_alloc_user_space()
and cleaned up; ioctl structures annotated.

In handling of VIDIOCSWIN for 32bit on 64bit platforms:
	* switched to compat_alloc_user_space()
	* fixed memory corruption in copying arguments from userland
	* fixed arithmetic overflows
	* added missing checks for get_user() results
	  and corresponding returns with -EFAULT.

 - afs and rxrpc switched to kvec; definition of kvec moved to uio.h (duh).
 - afs/mntpt.c got missing cast added.

at that point afs is sparse-clean and rxrpc has only one remaining warning
(setsockopt from local variable, protected by set_fs()).
