There are three kind of parse functions provided by PNP acpi/bios:
- get current resources
- set resources
- get possible resources
The first two may be needed later at runtime.
The possible resource settings should never change dynamically.
And even if this would make any sense (I doubt it), the current implementation
only parses possible resource settings at early init time:
-> declare all the option parsing __init

Make pnp_activate_dev() and pnp_disable_dev() return only 0 (success) or a
negative error value, as pci_enable_device() and pci_disable_device() do.
Previously they returned:
0: device was already active (or disabled)
1: we just activated (or disabled) device
<0: -EBUSY or error from pnp_start_dev() (or pnp_stop_dev())
Now we return only 0 (device is active or disabled) or <0 (error).
All in-tree callers either ignore the return values or check only for
errors (negative values).

raid5's 'make_request' function calls generic_make_request on underlying
devices and if we run out of stripe heads, it could end up waiting for one of
those requests to complete. This is bad as recursive calls to
generic_make_request go on a queue and are not even attempted until
make_request completes.
So: don't make any generic_make_request calls in raid5 make_request until all
waiting has been done. We do this by simply setting STRIPE_HANDLE instead of
calling handle_stripe().
If we need more stripe_heads, raid5d will get called to process the pending
stripe_heads which will call generic_make_request from a
This change by itself causes a performance hit. So add a change so that
raid5_activate_delayed is only called at unplug time, never in raid5. This
seems to bring back the performance numbers. Calling it in raid5d was
sometimes too soon...

Due to possible deadlock issues we need to use a schedule work to kobject_del
an 'rdev' object from a different thread.
A recent change means that kobject_add no longer gets a refernce, and
kobject_del doesn't put a reference. Consequently, we need to explicitly hold
a reference to ensure that the last reference isn't dropped before the
scheduled work get a chance to call kobject_del.
Also, rename delayed_delete to md_delayed_delete to that it is more obvious in
a stack trace which code is to blame.

Currently, a given device is "claimed" by a particular array so that it cannot
be used by other arrays.
This is not ideal for DDF and other metadata schemes which have their own
partitioning concept.
So for externally managed metadata, just claim the device for md in general,
require that "offset" and "size" are set properly for each device, and make
sure that if a device is included in different arrays then the active sections
do not overlap.
This involves adding another flag to the rdev which makes it awkward to set
"->flags = 0" to clear certain flags. So now clear flags explicitly by name
when we want to clear things.

If you try to start an array for which the number of raid disks is listed as
zero, md will currently try to read metadata off any devices that have been
given. This was done because the value of raid_disks is used to signal
whether array details have been provided by userspace (raid_disks > 0) or must
be read from the devices (raid_disks == 0).
However for an array without persistent metadata (or with externally managed
metadata) this is the wrong thing to do. So we add a test in do_md_run to
give an error if raid_disks is zero for non-persistent arrays.
This requires that mddev->persistent is set corrently at this point, which it
currently isn't for in-kernel autodetected arrays.
So set ->persistent for autodetect arrays, and remove the settign in
super_*_validate which is now redundant.
Also clear ->persistent when stopping an array so it is consistently zero when
starting an array.

This allows userspace to control resync/reshape progress and synchronise it
with other activities, such as shared access in a SAN, or backing up critical
sections during a tricky reshape.
Writing a number of sectors (which must be a multiple of the chunk size if
such is meaningful) causes a resync to pause when it gets to that point.

metdata in use
When a device fails, we must not allow an further writes to the array until
the device failure has been recorded in array metadata. When metadata is
managed externally, this requires some synchronisation...
Allow/require userspace to explicitly remove failed devices from active
service in the array by writing 'none' to the 'slot' attribute. If this
reduces the number of failed devices to 0, the write block will automatically
be lowered.

- Add a state flag 'external' to indicate that the metadata is managed
externally (by user-space) so important changes need to be
left of user-space to handle.
Alternates are non-persistant ('none') where there is no stable metadata -
after the array is stopped there is no record of it's status - and
internal which can be version 0.90 or version 1.x
These are selected by writing to the 'metadata' attribute.
- move the updating of superblocks (sync_sbs) to after we have checked if
there are any superblocks or not.
- New array state 'write_pending'. This means that the metadata records
the array as 'clean', but a write has been requested, so the metadata has
to be updated to record a 'dirty' array before the write can continue.
This change is reported to md by writing 'active' to the array_state
attribute.
- tidy up marking of sb_dirty:
- don't set sb_dirty when resync finishes as md_check_recovery
calls md_update_sb when the sync thread finishes anyway.
- Don't set sb_dirty in multipath_run as the array might not be dirty.
- don't mark superblock dirty when switching to 'clean' if there
is no internal superblock (if external, userspace can choose to
update the superblock whenever it chooses to).

Currently an md array with a write-intent bitmap does not updated that bitmap
to reflect successful partial resync. Rather the entire bitmap is updated
when the resync completes.
This is because there is no guarentee that resync requests will complete in
order, and tracking each request individually is unnecessarily burdensome.
However there is value in regularly updating the bitmap, so add code to
periodically pause while all pending sync requests complete, then update the
bitmap. Doing this only every few seconds (the same as the bitmap update
time) does not notciably affect resync performance.

The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits
to get the color from vc_video_erase_char. For a monochrome display
however the attribute does not contain any color, only attribute bits.
Furthermore the reverse bit is lost because it is shifted out, the
resulting color is always 0.
This can bee seen on a monochrome console either directly or by setting it
to inverse mode via "setterm -inversescreen on" . Text is written with
correct color, fb_fillrects from a bit_clear / bit_clear_margins will get
wrong colors.

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.
This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.
Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.

Avoid displaying garbage on unused framebuffers. For most users a single
framebuffer is used together with fbcon. sm501fb supports two framebuffers
where one often is assigned to fbcon and the other one is left unused during
the boot.
The problem here is that framebuffers not in use by fbcon happen to display
garbage. This can easily be solved by making sure that framebuffer memory and
palette ram are cleared.
The problem can be observed by using looking at the panel output (fb1) after
booting the kernel with fbcon on crt (fb0). This is the default
configuration. It's also possible to watch the garbage on the crt framebuffer
by passing "fbcon=map:1" on the kernel cmdline. This will assign fbcon to the
panel (fb1) and leave the crt (fb0) unused.

This patch makes it possible to control panel pins usage with flags passed
from the platform data. Without this patch the sm501fb driver always controls
the VBIASEN and FPEN pins. The polarity and use of these pins are very
platform specific, so this patch introduces the flags
SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable
the use of these pins.
This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH
platforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver
control the FPEN and VBIASEN pins like today just results in lcd panel
flicker.

nvidiafb: Panel is TMDS
nvidiafb: unable to setup MTRR
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000)
In my .config I presently have:
CONFIG_FIRMWARE_EDID=y
CONFIG_FB_DDC=y
CONFIG_FB_NVIDIA_I2C=y
I've not tried fiddling with these options, as I haven't the vaguest idea
what I should be looking at.
As a workaround, simply groveling for a new mode based on the probed
dimensions seems to work ok. While it would be nice to debug this further
and sort out why the panel information is bogus, I think it's still worth
retrying the mode based on the panel information at hand as a last-ditch
effort, rather than simply bailing out completely.

__ALIGN_MASK() is an internal implementation detail of ALIGN(). Let's not
needlessly fatten the interface in this driver.

Fix bug identified by Marcio Buss in
http://bugzilla.kernel.org/show_bug.cgi?id=9565 - neofb can overwrite a field
in the fb_info struct.
This fix will result in truncated device identification strings - perhaps
fb_innfo.fix.id can be made larger?
