[PATCH] sysctl: C99 convert arch/sh64/kernel/traps.c and remove ABI breakage
While doing the C99 conversion I notices that the top level sh64 directory was
using the binary number for CTL_KERN. That is a no-no so I removed the
support for the sysctl binary interface only leaving sysctl /proc support.
At least the sysctl tables were placed at the end of the list so user space
did not see this mistake.

[PATCH] sysctl: C99 convert arch/mips/lasat/sysctl.c and remove ABI breakage
While C99 converting the ctl_table initializers I realized that the binary
sysctl numbers were in conflict with the binary values under CTL_KERN.
Including CTL_KERN KERN_VERSION as used by glibc. So I just removed the
sysctl binary interface for these values, as it was unsupportable.
Luckily these sysctl were inserted at the end of the sysctl list so this bug
was not visible to userspace.

[PATCH] sysctl: C99 convert arch/ia64/kernel/perfmon and remove ABI breakage
This convters the sysctl ctl_tables to use C99 initializers. While I was
looking at it I discovered it was using a portion of the sysctl binary
addresses space under CTL_KERN KERN_OSTYPE which was completely inappropriate.
So I completely removed all of the sysctl binary names, to remove and avoid
the ABI conflict.

By not using the enumeration in sysctl.h (or even understanding it) the SN
platform placed their arch specific xpc directory on top of CTL_KERN and only
because they didn't have 4 entries in their xpc directory got lucky and didn't
break glibc.
This is totally irresponsible. So this patch entirely removes sys_sysctl
support from their sysctl code. Hopefully they don't have ascii name
conflicts as well.
And now that they have no ABI numbers add them to the end instead of the
sysctl list instead of the head so nothing else will be overridden.

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

There are quite a lot of files which include it but don't actually need

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.

[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.

[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.

[POWERPC] Open Firmware serial port driver
This can be used for serial ports that are connected to an
OF platform bus but are not autodetected by the lecacy
serial support.
It will automatically take over devices that come from the
legacy serial detection, which usually is only one device.
In some cases, rtas may be set up to use the serial port
in the firmware, which allows easier debugging before probing
the serial ports. In this case, the "used-by-rtas" property
must be set by the firmware. This patch also adds code to the
legacy serial driver to check for this.

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.

When CONFIG_PREEMPT is not set, it also moves one branch instruction from

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.
