Paul Fulghum af69c7f924 [PATCH] generic HDLC synclink config mismatch fix
Fix compile errors on mismatch between generic HDLC and synclink drivers.

Notes:

generic HDLC support for synclink drivers is *optional* so you can't just
use depend on in Kconfig

This solution is deemed the best after 7 months of review and criticism by
many developers including AKPM.  Read the threads on LKML before posting
about this solution.

Lennert Buytenhek a4ed06ad83 [PATCH] amba-pl010: clear error flags on rx error
The pl010 primecell documentation specifies that an error indicated via RSR
should be cleared by a write to ECR.  We didn't do this, which was causing
errors to be re-reported on every call to pl010_rx_chars().

Doing a write to ECR once we detect an error appears to prevent the ep93xx
console UART driver from going into a mode where it reports "ttyAM0: X
input overrun(s)" every couple of keystrokes.

Torsten Ertbjerg Rasmussen f9231a0ca1 [PATCH] rtc: ds1743 support
The real time clocks ds1742 and ds1743 differs only in the size of the
nvram.  This patch changes the existing ds1742 driver to support also
ds1743.  The main change is that the nvram size is determined from the
resource attached to the device.

The patch have benefitted from suggestions from Atsushi Nemeto, who is the
author of the ds1742 driver.

ide-scsi for things like tape drives.  If you compile in the CD driver this
works out but if you want them modular you need an option to ensure that
whoever loads first the right things happen.

This replaces the original draft patch which leaked a scsi host reference

This a set of fixes mostly to make the driver actually work:

1. Actually select the line for setting parameters and receiver

2. Select the line for receive and transmit interrupt handling correctly.
3. Report the transmitter empty state correctly.
4. Set the I/O type of ports correctly.
5. Perform polled transmission correctly.
6. Don't fix the console line at ttyS3.
7. Magic SysRq support.
8. Various small bits here and there.

David Brownell db68b189f4 [PATCH] add rtc-omap driver
This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips.  (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event.  Once that's fixed, a patch will be needed.

Kristian Kielhofner 0d75565f1e [PATCH] PCEngines WRAP LED Support
A driver for the PCEngines WRAP boards (http://www.pcengines.ch), which are
very similar to the Soekris net4801 (same NS SC1100 geode reference
design).

The LEDs on the WRAP are on different GPIO lines and I have modified and
copied the net48xx error led support for this.  It also includes support
for an "extra" led (in addition to error).  The three LEDs on the WRAP are
at GPIO lines 2,3,18 (WRAP LEDs from left to right).  This driver gives
access to the second and third LEDs by twiddling GPIO lines 3 & 18.

Because these boards are so similar to the net48xx, I basically sed-ed that
driver to form the basis for leds-wrap.c.  The only changes from
leds-net48xx.c are:

 - #define WRAP_EXTRA_LED_GPIO

 - name changes

 - duplicate relevant sections to provide support for the "extra" led

 - reverse the various *_led_set values.  The WRAP is "backwards" from the
   net48xx, and these needed to be updated for that.

Clean up several code points in which the return code from misc_register is
not handled properly.

Several modules failed to deregister various hooks when misc_register fails,
and this patch cleans them up.  Also there are a few modules that legitimately
don't care about the failure status of misc register.  These drivers however
unilaterally call misc_deregister on module unload.

Since misc_register doesn't initialize the list_head in the init_routine if it
fails, the deregister operation is at risk for oopsing when list_del is
called.  The initial solution was to manually init the list in the miscdev
structure in each of those modules, but the consensus in this thread was to
consolodate and do that universally inside misc_register.

Paul B Schroeder e0980dafa3 [PATCH] Exar quad port serial
This is on our "Envoy" boxes which we have, according to the documentation, an
"Exar ST16C554/554D Quad UART with 16-byte Fifo's".  The box also has two
other "on-board" serial ports and a modem chip.

The two on-board serial UARTs were being detected along with the first two
Exar UARTs.  The last two Exar UARTs were not showing up and neither was the
modem.

This patch was the only way I could the kernel to see beyond the standard four
serial ports and get all four of the Exar UARTs to show up.

Alexey Dobriyan b4178ab58a [PATCH] paride_register(): shuffle return values
paride_register() returns 1 on success, 0 on failure and module init
code looks like

	static int __init foo_init(void)
	{
		return paride_register(&foo) - 1;
	}

which is not what one get used to. Converted to usual 0/-E convention.

In case of kbic driver, unwind registration. It was just

	return (paride_register(&k951)||paride_register(&k971))-1;

  In order for spi_busnum_to_master to work spi master devices must be linked

  class_obj_subsys.kset is used and we can't enumerate the master devices.

Peter Zijlstra 9a2239b117 [PATCH] lockdep: fix ide/proc interaction
rmmod/3080 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
   (proc_subdir_lock){--..}, at: [<c04a33b0>] remove_proc_entry+0x40/0x191

  and this task is already holding:
   (ide_lock){++..}, at: [<c05651a2>] ide_unregister_subdriver+0x39/0xc8
  which would create a new lock dependency:
   (ide_lock){++..} -> (proc_subdir_lock){--..}

  but this new dependency connects a hard-irq-safe lock:
   (ide_lock){++..}
  ... which became hard-irq-safe at:
    [<c043c458>] lock_acquire+0x4b/0x6b
    [<c06129d7>] _spin_lock_irqsave+0x22/0x32
    [<c0567870>] ide_intr+0x17/0x1a9
    [<c044eb31>] handle_IRQ_event+0x20/0x4d
    [<c044ebf2>] __do_IRQ+0x94/0xef
    [<c0406771>] do_IRQ+0x9e/0xbd

  to a hard-irq-unsafe lock:
   (proc_subdir_lock){--..}
  ... which became hard-irq-unsafe at:
  ...  [<c043c458>] lock_acquire+0x4b/0x6b
    [<c06126ab>] _spin_lock+0x19/0x28

    [<c07c1844>] proc_root_init+0x4c/0xe9
    [<c07ad703>] start_kernel+0x294/0x3b3

Move ide_remove_proc_entries() out from under ide_lock; there is nothing
that indicates that this is needed.

In specific, the call to ide_add_proc_entries() is unprotected, and there
is nothing else in the file using the respective ->proc fields. Also the
lock order around destroy_proc_ide_interface() suggests this.

Alan sayeth:

  proc_ide_write_settings walks the setting list under ide_setting_sem, read
  ditto.  remove_proc_entry is doing proc side housekeeping.

  Looks fine to me, although that old code is such a mess anything could be
  going on.
