a bunch of trivial ->read() and ->write() instances (and their procfs
relatives) __user-annotated.  All chunks are independent, but IMO not
worth splitting.

Independent minor bits caught by sparse:

 - paride.h mixing void and int in ? :, used always in a void context
   ide-iops.c return insw() - insw is void()
 - scsi/constants.c uses undefined macros in #if; added #define to 0 in
   case that used to leave it undefined
 - usb/host/hcd.h: fixed-point arithmetics in constant
 - fs/exec.c: missing UL on a large constant
 - fs/locks.c: #if where #ifdef should've been
 - fs.h: missing UL on MAX_LFS_FILESIZE in 64bit case

	fs/*, fs/proc/*, fs/nfsd/*, fs/autofs4/* 

The only interdependent group is the fs/autofs4/* stuff.

rest of pointers in sg ioctl arguments made __user.

scsi_ioctl() and scsi_ioctl_send_command() switched to __user *;
scsi/scsi_ioctl.c annotated.

scsi_cmd_ioctl() switched to __user *, block/scsi_ioctl.c annotated.

copying moved into sg_io()

The kernel instance (packet_command) has kernel pointers, userland one -
__user ones. Surprise.

Speaking of conflicts...  Here's another half of a do_utimes() patch,
same story as on ppc64:

into ppc970.osdl.org:/home/torvalds/v2.6/linux

into ppc970.osdl.org:/home/torvalds/v2.6/linux

into ppc970.osdl.org:/home/torvalds/v2.6/linux

into ppc970.osdl.org:/home/torvalds/v2.6/linux

oh, hell - I missed this one when carving the thing out of big patch ;-/

into kernel.bkbits.net:/home/davem/net-2.6

Fix a missing initialization in the sparse __user annotation work for OSS.
Signed-off-by: Linus Torvalds <torvalds@osdl.org>

into kernel.bkbits.net:/home/davem/net-2.6

into kernel.bkbits.net:/home/davem/sparc-2.6

This also fixes a terminally broken sys32_utimes() implementation.

Don't need all the network sysfs code if CONFIG_SYSFS is not enabled.
Also:
	* netdev_sysfs_unregister is declaration mismatch
	* if netdev_sysfs_register fails print a warning.
	  Need to still mark it as registered so the unregister_netdevice works,
	  but we will probably end up leaking memory in that case.

As the comment in the code suggests, nobody really uses this so nobody
will notice the difference :) Still, let's make it correct while we're
at it.

1) Add sysctl to control rcvbuf moderation, off for now.
2) Set default winscale to zero.
