Implement new character device driver to allow access from user space
to the operator panel display present on IBM Power Systems machines
with FSPs.
This will allow status information to be presented on the display which
is visible to a user.
The driver implements a character buffer which a user can read/write
by accessing the device (/dev/op_panel). This buffer is then displayed on
the operator panel display. Any attempt to write past the last character
position will have no effect and attempts to write more characters than
the size of the display will be truncated. The device may only be accessed
by a single process at a time.

PowerPC is the last architecture using the GEN_RTC driver on some
machines, but we can migrate them all to using the RTC_DRV_GENERIC
driver instead now.
This moves over the CONFIG_GEN_RTC option from drivers/char into
arch/powerpc/platforms/Kconfig and makes it just select the
replacement driver instead, for the only reason of not breaking
existing defconfig and .config files that users may have.

We only depend on the intel-gtt module for GTT frobbign on older gens.
The intel_agp module is optional, except for UMS and some old XvMC
userland on gen3. So make AGP support optional. As before, we will
fail the i915 init for UMS and gen3 KMS the same as before if
intel_agp isn't around.
intel-gtt.c is left with a somewhat ugly ifdef mess, but I'm going
to save that for a later cleaning.
At least my gen2 still works with the patch and CONFIG_AGP=n.

Since ramoops was converted to pstore, it has nothing to do with character
devices nowadays. Instead, today it is just a RAM backend for pstore.
The patch just moves things around. There are a few changes were needed
because of the move:
1. Kconfig and Makefiles fixups, of course.
2. In pstore/ram.c we have to play a bit with MODULE_PARAM_PREFIX, this
is needed to keep user experience the same as with ramoops driver
(i.e. so that ramoops.foo kernel command line arguments would still
work).

The first version of this patch proposed an arch/tile/drivers/ directory,
but the consensus was that this was probably a poor choice for a place to
group Tilera-specific drivers, and that in any case grouping by platform
was discouraged, and grouping by function was preferred.
This version of the patch addresses various issues raised in the
community, primarily the absence of sysfs integration. The sysfs
integration now handles passing information on sector size, page size,
and total partition size to userspace as well. In addition, we now
use a single "struct cdev" to manage all the partition minor devices,
and dynamically discover the correct number of partitions from the
hypervisor rather than using a module_param with a default value.
This driver has no particular "peer" drivers it can be grouped with.
It is sort of like an MTD driver for SPI ROM, but it doesn't group well
with the other MTD devices since it relies on hypervisor virtualization
to handle many of the irritating aspects of flash ROM management: sector
awareness, background read for sub-sector writes, bit examination to
determine whether a sector erase needs to be issued, etc. It is in fact
more like an EEPROM driver, but the hypervisor virtualization does require
a "flush" command if you wish to commit a sector write prior to writing
to a different sector, and this is sufficiently different from generic
I2C/SPI EEPROMs that as a result it doesn't group well with them either.
The simple character device is already in use by a range of Tilera
SPI ROM management tools, as well as by customers. In addition, using
the simple character device actually simplifies the userspace tools,
since they don't need to manage sector erase, background read, etc.
This both simplifies the code (since we can uniformly manage plain files
and the SPI ROM) as well as makes the user code portable to non-Linux
platforms that don't offer the same MTD ioctls.

The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c.
The new driver has been in the tree for a little while, and has received

removal around 2.6.40 would be good, provided we're not missing critical

The tty locking now follows the rules for mutexes, so
we can replace the BKL usage with a new subsystem
wide mutex.
Using a regular mutex here will change the behaviour
when blocked on the BTM from spinning to sleeping,
but that should not be visible to the user.
Using the mutex also means that all the BTM is now

This patch introduces a new hypervisor console (HVC) back-end that provides
terminal access over the z/VM inter-user communication vehicle (IUCV).
The z/VM IUCV communication is independent of the regular tcp/ip network
and allows access even if there is no network connection between two
z/VM guest virtual machines.
The z/VM IUCV hypervisor console back-end helps the user to access a
z/VM guest virtual machine that lacks of network connectivity; and thus,
provides a "full-screen" terminal alternative to 3215/3270 terminal sessions.
Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of
HVC terminals using a z/VM IUCV back-end.
A recent version of the s390-tools package is required to establish a
terminal connection to a z/VM IUCV hypervisor console back-end.

This adds a new backend for the hvc console based on the low-level
udbg callbacks. This effectively implements a working runtime console
in terms of the simple udbg primitives. This is kind of a hack -
since udbg isn't something you really want to be using routinely - but
it's really useful during bringup.
This can be used to quickly implement a userspace-usable console while
you're working on a proper driver for whatever console I/O device the
hardware has. Or, it can be used to avoid writing a full blown
tty/console driver entirely for quick-and-dirty I/O hardware that will
later be replaced by something else.

This patch tries to change hvc_console to not use request_irq/free_irq if
the backend does not use irqs. This allows virtio_console to use hvc_console
without having a linker reference to request_irq/free_irq.
In addition, together with patch 2/3 it improves the performance for virtio
console input. (an earlier version of this patch was tested by Yajin on lguest)
The irq specific code is moved to hvc_irq.c and selected by the drivers that
use irqs (System p, System i, XEN).
I replaced "int irq" with the opaque "int data". The request_irq and
free_irq calls are replaced with notifier_add and notifier_del. I have also
changed the code a bit to call the notifier_add and notifier_del inside the
spinlock area as the callbacks are found via hp->ops.
Changes since last version:
o remove ifdef
o reintroduce "irq_requested" as "notified"
o cleanups, sparse..
I did not move the timer based polling into a separate polling scheme. I
played with several variants, but it seems we need to sleep/schedule in
a thread even for irq based consoles, as there are throttleing and buffer
size constraints.
I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access
the irq_requested element.
Feedback is appreciated. virtio_console is currently the only available console
for kvm on s390. I plan to push this change as soon as all affected parties
agree on it. I would love to get test results from System p, Xen etc.

Manual fixup of:
arch/powerpc/Kconfig
|
|
Adds a character driver for BSR support on IBM POWER systems including
Power5 and Power6. The BSR is an optional processor facility not currently
implemented by any other processors. It's primary purpose is fast large SMP
synchronization. More details on the BSR are in comments to the code which
follows. This patch adds BSR driver to pseries_defconfig.

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
