socket references are pointers, not integers.

From Randy Dunlap.

From Dominik Brodowski: 

A few missing exports -- even though the cpu_sysdev_class isn't strictly
needed now, I need it for a few ACPI-related patches I'll send out in a
minute.

A recent change to the 2.6.0 kernel has changed the behavior of opening a
block device with the O_EXCL flag.  This can cause fsck.jfs to fail to
replay the journal when a file system is mounted read-only.

The JFS utilities have been fixed, and it is recommended that any users of
JFS update the utilities to version 1.1.3.

Add template for Nehemiah.

This also fixes the bug with MAP_SEM being potentially
interpreted as VM_SHARED.

This moves the mapping of PROT_* bits to VM_* bits from mmap.c to the
common header file <linux/mman.h>.  The mapping is needed for mprotect
too.

	old_decode_dev()/old_encode_dev() added where needed in other
filesystems.  Parts in different filesystems are independent, but IMO
it's not worse splitting into a dozen of half-kilobyte patches.

	nfs_fattr->rdev switched to dev_t; code that unpacks on-the-wire
attributes does explicit conversion now.

	HPFS code that uses EAs for storing i_rdev/i_mode/i_uid/i_gid
sanitized.

	Similar fix for UFS; touching device node (and they have 32bit
dev_t) ends up killing upper 16 bits, which makes for very unhappy
*BSD, since that turns /dev/ad0s1 into alias of /dev/ad0.  Again, for
now we store on-disk value in private part of inode and use it instead
of ->i_rdev in ->write_inode().

	Fix for JFS handling of device nodes; it has 32bit on-disk device
numbers, shoves them into 16bit (->i_rdev) when inode is read and writes
them back truncated when inode is written to disk.  For now (and 2.4 will
have to do the same permanently) we store the original value in private
part of inode and use it instead of ->i_rdev in ->write_inode(); mknod()
sets it at the same time as ->i_rdev.  It will become unnecessary when
dev_t becomes wider than 16 bits, but for now we need it.

	Fix for endianness bug in UDF: it writes major and minor as 32bit
host-endian and reads them as 32bit little-endian; obviously a bad idea
on big-endian boxen ;-)  Needed both for 2.4 and 2.6.

beginning of fs side work:
	* new helpers - old_valid_dev(), old_encode_dev() and old_decode_dev()
	* old_valid_dev() checks if dev_t value is OK for old filesystems
(i.e. both major and minor are below 256).
	* old_valid_dev() calls are added in ->mknod() instances that care
about dev_t values (disk-backed and network ones).
	* old_encode_dev() and old_decode_dev() convert dev_t -> u16
and u16 -> dev_t resp; currently these are no-ops, places that use current
formar (minor in bits 0--7, major in bits 8--15) will switch to these before
we widen dev_t.

	kdev_t, to_kdev_t(), etc. are gone - there is no more objects
of that type and no remaining callers of these functions.

	the last kdev_t object is gone; ->i_rdev switched to dev_t.

	tty redirect handling sanitized.  Such ttys (/dev/tty and
/dev/console) get a different file_operations; its ->write() handles
redirects; checks for file->f_op == &tty_fops updated, checks for
major:minor being that of a redirector replaced with check for
->f_op->write value.  Piece of code in tty_io.c that had been #if 0
since 0.99<something> had been finally put out of its misery. kdev_val()
is gone.

	cdevname() killed, there was only one remaining user
(tty_paranoia_check()) and in that case cdevname() was worse
than plain major:minor (basically, it's "you've got corrupted
inode that was supposed to belong to tty device; here's what
I'd found in ->i_rdev")

	cciss cleanup - instead of playing with device numbers, we add
helper functions that get host and drive structures by gendisk and use
them in open/ioctl/release, same as had been done for cpqarray.

	paride/pt.c cleanups - passing pointer to pt_unit instead of index
in array; same as had been done for pd/pcd/pf.

	floppy98 ->probe() forgot to set *part to 0; fixed.

	misc trivial cleanups

- Don't write the current time back to the RTC on suspend - we may
  jump over a programmed wakeup alarm.
- Restore SA1100 GPIO output state

- Suspend and resume system devices.
- If device suspend fails, don't suspend.

Some ARM CPUs don't allow CP15 CR1 control register to be read.
Therefore, to ensure that the value hits the control register on
Xscale, read back the CP15 CR0 ID register instead.

On ARM, we oops when we detect that an interrupt handler has unbalanced
the preempt count.  We should restore the preempt count when we started
to handle the interrupt and then cause the oops.
