[PATCH] sysctl: cdrom: don't set de->owner

There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races.  While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted.  Once the sysctl is
unregistered it cannot be found.  Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.

So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.

[PATCH] sysctl: x25: remove unnecessary insert_at_head from register_sysctl_table

There has not been much maintenance on sysctl in years, and as a result is
there is a lot to do to allow future interesting work to happen, and being
ambitious I'm trying to do it all at once :)

The patches in this series fall into several general categories.

- Removal of useless attempts to override the standard sysctls

- Registers of sysctl numbers in sysctl.h so someone else does not use
  the magic number and conflict.

- C99 conversions so it becomes possible to change the layout of
  struct ctl_table without breaking everything.

- Removal of useless claims of module ownership, in the proc dir entries

- Removal of sys_sysctl support where people had used conflicting sysctl
  numbers. Trying to break glibc or other applications by changing the
  ABI is not cool.  9 instances of this in the kernel seems a little
  extreme.

- General enhancements when I got the junk I could see out.

This patch:

Since x25 uses unique binary numbers inserting yourself at the head of the
search list for sysctls so you can override already registered sysctls is
pointless.

[PATCH] remove many unneeded #includes of sched.h

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

[PATCH] knfsd: allow the server to provide a gid list when using AUTH_UNIX authentication

AUTH_UNIX authentication (the standard with NFS) has a limit of 16 groups ids.
 This causes problems for people in more than 16 groups.

So allow the server to map a uid into a list of group ids based on local
knowledge rather depending on the (possibly truncated) list from the client.

If there is no process on the server responding to upcalls, the gidlist in the

[PATCH] knfsd: add some new fsid types

Add support for using a filesystem UUID to identify and export point in the
filehandle.

For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room.  For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.

When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.

[PATCH] knfsd: tidy up choice of filesystem-identifier when creating a filehandle

no need to verify the the numbers are valid for this export, and they must be
(we used them to find this export).

This allows us to simplify the fsid selection code.

Also change "ref_fh_version" and "ref_fh_fsid_type" to "version" and
"fsid_type", as the important thing isn't that they are the version/type of

[PATCH] 8250 UART backup timer

The patch below works around a minor bug found in the UART of the remote
management card used in many HP ia64 and parisc servers (aka the Diva
UARTs).  The problem is that the UART does not reassert the THRE interrupt
if it has been previously cleared and the IIR THRI bit is re-enabled.  This
can produce a very annoying failure mode when used as a serial console,
allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it
into working again (ie.  an unattended reboot could stall).

To solve this problem, a backup timer is introduced that runs alongside the
standard interrupt driven mechanism.  This timer wakes up periodically,
checks for a hang condition and gets characters moving again.  This backup
mechanism is only enabled if the UART is detected as having this problem,
so systems without these UARTs will have no additional overhead.

This version of the patch incorporates previous comments from Pavel and
removes races in the bug detection code.  The test is now done before the
irq linking to prevent races with interrupt handler clearing the THRE
interrupt.  Short delays and syncs are also added to ensure the device is
able to update register state before the result is tested.

Aristeu says:

  this was tested on the following HP machines and solved the problem:
  rx2600, rx2620, rx1600 and rx1620s.

hpa says:

  I have seen this same bug in soft UART IP from "a major vendor."

[PATCH] ia64: fix noncoherent DMA API so devres builds

On ia64, drivers/base/dma-mapping.c doesn't build because it calls
dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be
terminally broken; the calls end up generating errors like

    drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release':
    drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent'

because the multiple levels of macro expansion in <asm/dma-mapping.h> and
<asm/machvec.h> end up turning a call to dma_free_noncoherent() into
ia64_mv.platform_dma_free_coherent (instead of the intended
ia64_mv.dma_free_coherent).

This patch fixes this by converting dma_{alloc,free}_noncoherent() into
inline functions that call the corresponding coherent functions, instead of
trying to do this with macros.

[POWERPC] Use udbg_early_init() on ppc32

udbg_early_init() is a function used on 64 bit systems, which
initializes whichever early udbg backend is configured.  This function
is not called on 32-bit, however if btext early debug is enabled it
does have an explicit, inline, #ifdef-ed assignment performing
analagous initialization.

This patch makes things more uniform by folding the btext
initialization as an option into udbg_early_init() and calling that
from the 32-bit setup path.

It will automatically take over devices that come from the

In some cases, rtas may be set up to use the serial port

the serial ports. In this case, the "used-by-rtas" property

[PATCH] Fix SAK_work workqueue initialization.

Somewhere in the rewrite of the work queues my cleanup of SAK handling
got broken.  Maybe I didn't retest it properly or possibly the API
was changing so fast I missed something.  Regardless currently
triggering a SAK now generates an ugly BUG_ON and kills the kernel.

Thanks to Alexey Dobriyan <adobriyan@openvz.org> for spotting this.

This modifies the use of SAK_work to initialize it when the data
structure it resides in is initialized, and to simply call
schedule_work when we need to generate a SAK.  I update both
data structures that have a SAK_work member for consistency.

All of the old PREPARE_WORK calls that are now gone.

If we call schedule_work again before it has processed it
has generated the first SAK it will simply ignore the duplicate
schedule_work request.

i2c: Stop using i2c_adapter.class_dev

Stop using i2c_adapter.class_dev, as it is going to be removed
soon. Luckily, there are only 4 RTC drivers affected.

i2c: Remove the warning on missing adapter device

Now that the i2c_adapter migration plan changed and we are going to
keep i2c_adapter.dev, it's no longer that urgent to add a proper device
to all i2c_adapter drivers. Thus is seems resonable to degrade the
warning asking authors to migrate their driver to a debug message.

i2c-amd8111: Proposed cleanups

Proposed cleanups to the i2c-amd8111 SMBus driver:
* Fold long lines.
* Add an explicit mask when writing the low byte of a word.
* Use I2C_SMBUS_BLOCK_MAX instead of hardcoding 32.
* Discard extra blank lines.
* Use boolean not instead of bitwise not for bit tests, it's clearer.
* Return -EBUSY rather than -1 on I/O resource conflict.
* Fix a race on device registration, initialization should be done
  before the bus is registered.

i2c-parport: Add support for One For All remote JP1 interface

This simple patch adds support to i2c-parport for the One For All remote
JP1 parallel port interfaces which can be found detailed at:

http://www.hifi-remote.com/jp1/hardware.shtml

These allow access to the internal configuration EEPROM on various
remote controls and there are a variety of Windows tools that make use
of this hardware. I have tested this patch with the "simple" parallel
port device and a One For All URC-7562 and confirmed that the data read
using the eeprom i2c driver matches that returned by the Windows "IR"

i2c: Add driver suspend/resume/shutdown support

Driver model updates for the I2C core:

 - Add new suspend(), resume(), and shutdown() methods.  Use them in the
   standard driver model style; document them.

 - Minor doc updates to highlight zero-initialized fields in drivers, and
   the driver model accessors for "clientdata".

If any i2c drivers were previously using the old suspend/resume calls
in "struct driver", they were getting warning messages ... and will
now no longer work.  Other than that, this patch changes no behaviors;
and it lets I2C drivers use conventional PM and shutdown support.

i2c-ali1563: Fix device initialization

The i2c-ali1563 initialization looks quite broken to me:
* If the I/O space isn't enabled, we forcibly set 3 bits in
  the PCI configuration space instead of just the one enabling
  the I/O space.
* After that we pretend to check if the write worked, but we
  don't actually read the new value from the register.
* It's probably not a good idea to enable the I/O space if no
  base address has been set.

So I propose the following changes to that part of the driver:
* Merge ali1563_enable() into ali1563_setup().
* Check the base address before the I/O space enabled bit.

[POWERPC] cell: pm_rtas_activat_signals routine cleanup

The code was setting up the debug bus for group 21 when profiling on the
event PPU CYCLES.  The debug bus is not actually used by the hardware
performance counters when counting PPU CYCLES.  Setting up the debug bus
for PPU CYCLES causes signal routing conflicts on the debug bus when
profiling PPU cycles and another PPU event.  This patch fixes the code to

PPU CYCLE events.
