regulator: sysfs attribute reduction (v2)
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.

regulator: improved mode error checks
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.

regulator: enable/disable refcounting
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

regulator: struct device - replace bus_id with dev_name(), dev_set_name()
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

V4L/DVB (10191a): Update MAINTAINERS entries on media drivers
This patch updates the MAINTAINERS entries for the media drivers.
We are doing a few changes during 2009 to improve patch handling for
drivers/media stuff.
Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb
driver maintainers ML, in order to keep track of patch merge requests and to
receive bug fixes. This list allows posting for everybody, but, in order to
avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other
development discussions and end-user forums happened on two separated ML (one
for V4L and another for DVB).
At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to
be the main upstream development mailing list for drivers/media, including V4L
and DVB core and drivers.
The choice for vger.kernel.org were due to the fact that most of upstream lists
are there. Also, its anti-spam filtering rules are better than what we
currently have at linuxtv.org.
For now, both video4linux-list and linux-dvb ML will remain active, but more
focused on end users. It is expected that those lists will gradually be
replaced also by linux-media@vger.kernel.org.
This patch reflect those changes at linux MAINTAINERS file.
Since the development and bug fix discussions will now happen at
linux-media@vger.kernel.org, this patch does the following changes
- replaces v4l-dvb-maintainer ML for the new
linux-media@vger.kernel.org;
- replaces video4linux ML for the new linux-media@vger.kernel.org;
While here, it also:
- Fixes the existing -git tree entries for drivers/media (since the
repository name changed);
- Adds the missing drivers/media -git tree entry on a few maintainers
entries that don't point to a tree.

V4L/DVB (10190): cx88: Fix some Kbuild troubles
As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:
drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':

cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'
With those configs:
CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m
After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.
What happens is that:
- cx88-i2c (part of cx8800) has some special rules if DVB;
- cx88-mpeg (cx8802 module) has also part of DVB init code;
- cx88-dvb has the rest of the dvb code;
- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.
So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.
Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.
While on this code, let's fix also a reported problem:

topology: Fix sparc64 build.
Due to changeset
ba84be2338d3a2b6020d39279335bb06fcd332e1 ("remove
linux/hardirq.h from asm-generic/local.h") the sparc64 build started
failing on drivers/base/topology.c:
drivers/base/topology.c: In function ‘show_physical_package_id’:
drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’

drivers/base/topology.c: In function ‘show_core_id’:
drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union
Adding the obvious fix of including asm/cpudata.h into asm/topology.h on
sparc64 doesn't fix it, in fact it makes things worse because of the
header file dependency chain:
linux/gfp.h --> linux/mmzone.h --> linux/topology.h -->
asm/topology.h --> asm/cpudata.h --> linux/percpu.h -->
linux/slab.h
which results in:
include/linux/slub_def.h: In function ‘kmalloc_large’:
include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’
include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function)

kconfig: add script to manipulate .config files on the command line
I often change single options in .config files. Instead of using
an editor or one of the frontends it's convenient to do this from
the command line. It's also useful to do from automated build scripts
when building different variants from a base config file.
I extracted most of the CONFIG manipulation code from one of my
build scripts into a new shell script scripts/config
The script is not integrated with the normal Kconfig machinery
and doesn't do any checking against Kconfig files, but just manipulates
that text format. This is always done at make time anyways.
I believe this script would be a useful standard addition for scripts/*
Sample usage:
./scripts/config --disable smp
Disable SMP in .config file
./scripts/config --file otherdir/.config --module e1000e
Enable E1000E as module in otherdir/.config
./scripts/config --state smp
y

Primarily his complaint was that shorter delays weren't visualized.
The reason for that was that too small delays will have their labels

This patch has a fix for this; for one, it makes the output wider,
so more will fit.
The second part is that smaller delays are now shown with a
much smaller font for the label; while this isn't per se

fix modules_install via NFS

make[2]: *** [_modinst_post] Error 2
make[1]: *** [sub-make] Error 2

with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
each test box (full path to this directory is the same on the build box and on
the test boxes). Then, I cd into <destdir>, run 'make modules_install' and get
the error above.
The issue turns out to be that we when we install firmware pick
up the list of firmware blobs from firmware/Makefile.
And this triggers the Makefile rules to update ihex2fw.
There were two solutions for this issue:
1) Move the list of firmware blobs to a separate file
2) Avoid ihex2fw rebuild by moving it to scripts
As I seriously beleive that the list of firmware blobs should be
done in a fundamental different way solution 2) was selected.

nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKT
Since nfsv4 allows LOCKT without an open, but the ->lock() method is a
file method, we fake up a struct file in the nfsv4 code with just the
fields we need initialized. But we forgot to initialize the file
operations, with the result that LOCKT never results in a call to the
filesystem's ->lock() method (if it exists).
We could just add that one more initialization. But this hack of faking
up a struct file with only some fields initialized seems the kind of
thing that might cause more problems in the future. We should either do
an open and get a real struct file, or make lock-testing an inode (not a
file) method.
This patch does the former.

stop_machine/cpu hotplug: fix disable_nonboot_cpus
disable_nonboot_cpus calls _cpu_down. But _cpu_down requires that the
caller already created the stop_machine workqueue (like cpu_down does).
Otherwise a call to stop_machine will lead to accesses to random memory
regions.
When introducing this new interface (
9ea09af3bd3090e8349ca2899ca2011bd94cda85
"stop_machine: introduce stop_machine_create/destroy") I missed the second
call site of _cpu_down.
So add the missing stop_machine_create/destroy calls to disable_nonboot_cpus
as well.

PCI PM: Avoid touching devices behind bridges in unknown state
It generally is better to avoid accessing devices behind bridges that
may not be in the D0 power state, because in that case the bridges'
secondary buses may not be accessible. For this reason, during the
early phase of resume (ie. with interrupts disabled), before
restoring the standard config registers of a device, check the power
state of the bridge the device is behind and postpone the restoration
of the device's config space, as well as any other operations that
would involve accessing the device, if that state is not D0.
In such cases the restoration of the device's config space will be
retried during the "normal" phase of resume (ie. with interrupts
enabled), so that the bridge can be put into D0 before that happens.
Also, save standard configuration registers of PCI devices during the
"normal" phase of suspend (ie. with interrupts enabled), so that the
bridges the devices are behind can be put into low power states (we
don't put bridges into low power states at the moment, but we may
want to do it in the future and it seems reasonable to design for
that).

There is a problem with the suspend and resume of PCI Express port

The scenario is that first, the PCI Express port driver calls
suspend and resume routines of each port service driver from its

respectively (which is correct), and second, the pcie_port_bus_type

Use the generic pci_common_swizzle() instead of arch-specific code.
Note that pci_common_swizzle() loops based on dev->bus->self, not
dev->bus->parent as the mips common_swizzle() did. I think they
are equivalent for this purpose.

PCI: add pci_common_swizzle() for INTx swizzling
This patch adds pci_common_swizzle(), which swizzles INTx values all the
way up to a root bridge.
This common implementation can replace several architecture-specific
ones. This should someday be combined with pci_get_interrupt_pin(),
but I left it separate for now to make reviewing easier.
