the SG_IO and SCSI_IOCTL_SEND_COMMAND ioctl's. That just
screws things up when the drive is mounted.

If somebody wants exclusive access, he should indicate that
at open time.

I've been trying to remove these, but apparently new ones crop up. Lets
just call it io scheduler, none of the ones in the kernel are using the
classic elevator algorithm.

As a result the size of vfat.o drops by 384 bytes in my build.

use the PCI layer instead to provide those for us.

* remove PCI_CACHE_LINE_SIZE workaround, PCI core already does
  this for us.  (main change)
* propagate pci_set_dma_mask return value
* add 'ULL' suffix to pci_set_dma_mask arg
* propagate pci_enable_device return value
* call pci_set_mwi, check and propagate its return value
* call pci_clear_mwi and pci_disable_device on close, and probe error
* call iounmap when cleaning up

Modifies drivers atm/eni.c, ide/pci/cmd64x.c, and
ide/pci/ns87415.c.  Ack'd by DaveM.

This implements the needed 'release' callback in order to make
videodev/sysfs happy again.

This reenables the CAPTURE button events in the sonypi driver, which
were lost with the latest patch...

This adds support for software controlled hard drive LED activity.

This is really nice on such machines as Apple Powerbooks, where there is
no such LED in the first place and the sleep/suspend LED isn't used for
anything when the machine is running.

Fix byte order of info parameter in ip6ip6_err().

into redhat.com:/spare/repo/net-drivers-2.5

* The PCI layer now handles incorrect cacheline size settings,
  as it should.  Remove our own workarounds.
* Move pci_set_mwi up much earlier in the probe process,
  and check its return value.
* Call pci_clear_mwi() in ->probe error handling
* Call pci_clear_mwi() in ->remove

This patch adds documentation for the contents of the /proc/stat file.

If journal_start() fails it returns an ERR_PTR.  Best not pass that into
journal_stop().

Ancient bug, reported by Hiroshi Inoue <inoueh@uranus.dti.ne.jp>:

 1. login to tty2 (not tty1)
 2. start kon (Kanji cONsole emulator, console which support
    Japanese characters)
 3. exit kon
 4. logout

It oopses in the debugging function check_tty_count(), walking a list_head
which has been list_del()'d.   Call trace is:

#0  check_tty_count (tty=0x10d42000, routine=0xc817b00 ".paths") at include/asm/processor.h:583
#1  0x022c6c00 in do_tty_hangup (data=0x10d42000) at drivers/char/tty_io.c:426
#2  0x022c6f60 in tty_vhangup (tty=0xc817b00) at drivers/char/tty_io.c:536
#3  0x022c6fcc in disassociate_ctty (on_exit=1) at drivers/char/tty_io.c:574
#4  0x02127aee in do_exit (code=0) at kernel/exit.c:718
#5  0x02127caa in do_group_exit (exit_code=0) at kernel/exit.c:796
#6  0x02127cbc in sys_exit_group (error_code=0) at kernel/exit.c:807

The tty refcount is zero, so everything seems consistent and sensible.  The
fix just uses list_del_init() on that list_head.


Heaven knows what the locking for tty->count is though.  Some bizarre mixture
of BKL, tty_sem and nothing at all.

Some drivers such as aha1542 and aic7xxx_old will call scsi_register() and
then, if some succeeding operations fails they will call scsi_unregister(),
without an intervening scsi_set_host().

This causes an oops in scsi_put_device(), because kobj->parent is NULL.

In other words, scsi_register() immediately followed by scsi_unregister()
is guaranteed to oops.

The patch makes scsi_host_dev_release() more robust against this usage
pattern.

It's good that swapon fails on a tmpfs file ("swapfile has holes"), but not
good that it then hangs up: note error from setup_swap_extents.
