There is no compelling need for this, but sysfs_notify_dirent is a
nicer interface and the change is good for consistency.

commit a2ed9615e3222645007fc19991aedf30eed3ecfd
fixed a bug with 'internal' bitmaps, but in the process broke
'in a file' bitmaps. So they are broken in 2.6.28
This fixes it, and needs to go in 2.6.28-stable.

Reimplement mode programming logic of pata_hpt366 such that it's
identical to that of IDE hpt366 driver. The differences were...
* pata_hpt366 used 0xCFFF8FFFF to mask pio modes and 0x3FFFFFFF dma
modes. IDE hpt366 uses 0xC1F8FFFF for PIO, 0x303800FF for MWDMA and
0x30070000 for UDMA.
* pata_hpt366 doesn't set 0x08000000 for PIO unless it's already set
and always turns it on for MWDMA/UDMA. IDE hpt366 doesn't bother
with the bit. It always uses what was there.
* IDE hpt366 always clears 0xC0000000. pata_hpt366 doesn't.

Certain ACPI implementations mess up IOCFG on _STM making libata
detect cable type incorrectly after a suspend/resume cycle. This
patch makes ata_piix save IOCFG on attach, use the saved value for
things which aren't dynamic and restore it on detach so that the next
driver also gets the BIOS initialized value.
This patch contains the following changes.
* makes ich_pata_cable_detect() use saved_iocfg.
* make piix_iocfg_bit18_quirk() take @host and use saved_iocfg.
* hpriv allocation moved upwards to save iocfg before doing anything
else.
This fixes bz#11879. Andreas Mohr reported and diagnosed the problem.

Add a basic DocBook manual for the regulator API. This is much more
skeletal than the existing text documentation, the main benefit is to
provide a skeleton for automatic generation of a manual based on the
kerneldoc for the API.
Since large portions of the text are lifted from the existing text format
documentation written by Liam Girdwood much of the credit belongs to
him.

Move regulator earlier in link sequence.
The regulator core currently initializes as a core_initcall() to be
available early ... but then it links way late, throwing away that
benefit, so regulators available at e.g. subsys_initcall() are not
available to subsystems which need to use them.

Clean up the sysfs interface to regulators by only exposing the
attributes that can be properly displayed. For example: when a
particular regulator method is needed to display the value, only
create that attribute when that method exists.
This cleaned-up interface is much more comprehensible. Most
regulators only support a subset of the possible methods, so
often more than half the attributes would be meaningless. Many
"not defined" values are no longer necessary. (But handling
of out-of-range values still looks a bit iffy.)
Documentation is updated to reflect that few of the attributes
are *always* present, and to briefly explain why a regulator may
not have a given attribute.
This adds object code, about a dozen bytes more than was removed
by the preceding patch, but saves a bunch of per-regulator data
associated with the now-removed attributes. So there's a net
reduction in memory footprint.

Minor bugfixes in handling of regulator modes:
- have the routine verifying regulator modes check against
the set of legal modes (!);
- have regulator_set_optimum_mode() verify the return value
of regulator_ops.get_optimum_mode(), like drms_uA_update();
- one call to regulator_ops.set_mode() treated zero as a
failure code; make this consistent with other callers.
Both regulator_set_mode() and regulator_set_optimum_mode() now
require valid_ops_mask to include REGULATOR_CHANGE_MODE; that
seems like a bugfix too.

Make the <linux/regulator.h> framework treat enable/disable call
pairs like the <linux/clk.h> and <linux/interrupt.h> frameworks do:
they're refcounted, so that different parts of a driver don't need
to put work into coordination that frameworks normally handle.
It's a minor object code shrink.
It also makes the regulator_is_disabled() kerneldoc say what it's
actually returning: return value is not a refcount, and may report
an error (e.g. I/O error from I2C).
It also fixes some minor regulator_put() goofage: removing unlocked
access to the enable state. (But still not making regulator put/get
match the refcounting pattern they invoke.)

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.
Thanks,
Kay

WiMAX can work without RFKILL, but it was missing a check to make sure
RFKILL is not being made a module with wimax compiled into the
kernel. This caused failed builds in s390, where CONFIG_INPUT is
always off.
When RFKILL is enabled, the code uses the input layer to report
hardware switch changes; thus, if RFKILL is enabled, INPUT has to be
too. It also needs to display some message when INPUT is disabled that
explains why WiMAX is not selectable.

Move the return on #defined(CONFIG_BUG) below the variable
declarations so it doesn't violate ISO C90.
On wimax_id_table_release() we want to do a debug check if CONFIG_BUG
is enabled. However, we also want the debug code to be always compiled
to ensure there is no bitrot. It will be optimized out by the compiler
when CONFIG_BUG is disabled.
