optval (and in case of getsockopt - optlen) made __user, changes
percolated down into the instances.

	ethtool_ioctl() annotated; it would go in the first compat_ioctl
chunk (trivial ones) if it wouldn't be right after SIOCGIFCONF mess; was
easier to split in that order...

	Switched to compat_alloc_user_space(), killed kmalloc and set_fs(),
annotated, somewhat cleaned up.

	Similar to previous - annotated, killed helper, made the thing
type-clean, cleaned up.

	annotated, killed useless (and type-buggering - void ** is not
assignment-compatible with foo **) helper, cleaned up.

	Annotated, cleaned up, wholesale copying of structure with
subsequeunt casts from hell replaced with get_user()/put_user() on
the fields we really need.

	blkpg ioctls handling switched to compat_alloc_user_space() (instead
of messing with set_fs()) and annotated.

	Whoever had done the translation apparently never heard of
big-endian boxen.  Replaced the kludge with get_user()/put_user() on
64bit values.  Note that
struct raw_config_request
{
        int     raw_minor;
        __u64   block_major;
        __u64   block_minor;
};
has __u64 on _all_ platforms and it is used as an integer in raw.c code.
The only reason why translation is needed at all is alignment for 64bit
values; block_major and block_minor themselves should be passed as-is.

	Breakage fixed, entire area annotated.

	Easy parts of compat_ioctl fixes - pure __user annotation.
In one place (SG_IO handling) replaced dereference of user pointer
with put_user() (why whoever had noticed that just put a FIXME instead
of obvios fix is a mistery...)

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

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.

This also fixes a terminally broken sys32_utimes() implementation.
