Some led hardware allows drivers to query the led state, and this patch
adds a hook to let the led class take advantage of that information when
available.
Without this functionality, when access to the led hardware is not
exclusive (i.e. firmware or hardware might change its state behind the
kernel's back), reality goes out of sync with the led class' idea of what
the led is doing, which is annoying at best.
Behaviour for drivers that do not or cannot read the led status is
unchanged.

Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.
This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).
At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.
The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.

[mszeredi@suse.cz] rewrite and split big patch into managable chunks
/proc/mounts in its current form lacks important information:
- propagation state
- root of mount for bind mounts
- the st_dev value used within the filesystem
- identifier for each mount and it's parent
It also suffers from the following problems:
- not easily extendable
- ambiguity of mountpoints within a chrooted environment
- doesn't distinguish between filesystem dependent and independent options
- doesn't distinguish between per mount and per super block options
This patch introduces /proc/<pid>/mountinfo which attempts to address
all these deficiencies.
Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is
extracted into separate functions.

Add a unique ID to each peer group using the IDR infrastructure. The
identifiers are reused after the peer group dissolves.
The IDR structures are protected by holding namepspace_sem for write
while allocating or deallocating IDs.
IDs are allocated when a previously unshared vfsmount becomes the
first member of a peer group. When a new member is added to an
existing group, the ID is copied from one of the old members.
IDs are freed when the last member of a peer group is unshared.
Setting the MNT_SHARED flag on members of a subtree is done as a
separate step, after all the IDs have been allocated. This way an
allocation failure can be cleaned up easilty, without affecting the
propagation state.
Based on design sketch by Al Viro.

The separation between algorithm and adapter was unsharp at places. This was
partly hidden by the fact, that the ISA-driver allowed just one instance and
had all private data in static variables. This patch makes neccessary
preparations to add a platform driver on top of the algorithm, while still
supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be
tested except that it builds.
Concerning the core struct i2c_algo_pca_data:
- A private data field was added, all hardware dependant data may go here.
Similar to other algorithms, now a pointer to this data is passed to the
adapter's functions. In order to make as less changes as possible to the
ISA-driver, it leaves the private data empty and still only uses its static
variables.
- A "reset_chip" function pointer was added; such a functionality must come
from the adapter, not the algorithm.
- use a variable "i2c_clock" instead of a function pointer "get_clock",
allowing for write access to a default in case a wrong value was supplied.
In the algorithm-file:
- move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h"
- now using per_instance timeout values (i2c_adap->timeout)
- error messages specify the device, not only the driver name
- restructure initialization to easily support "i2c_add_numbered_adapter"
- drop "retries" and "own" (i2c address) as they were unused
(The state-machine for I2C-communication was not touched.)
In the ISA-driver:
- adapt to new algorithm

Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.
In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'. And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero. 255/256 in three of the cases, and 0-1024 in another.
This patch fixes the report descriptor of this device before it enters the HID
parser.

Many vendors highspeed devices give erroneously fullspeed interval value in
endpoint descriptor for interrupt endpoints. This quirk fixes up that by
recalculating the right value for highspeed device.
At the time of hid configuration this quirk calculates which highspeed interval
value gives same interval delay as, or next smaller then, what it would be if
the original value would be interpreted as fullspeed value. In subsequent urbs
that new value is used instead.
Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more
descriptive printk reporting the fixup.
In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared
HID-keyboard. It reports value 16 which means 4,069s in highspeed while
obviously 16ms was intended. In this case quirk calculates new value to be 8
which gives when interpreted as highspeed value 16ms as wanted. The behavior of
the device was verified to be what expected both before and after the patch.

The RCU iterators used 'rcu_dereference()' on an already-fetched RCU

When we dereference a pointer protected by RCU, we need to make sure
that we only fetch the value _once_, because if the compiler ends up
re-loading it due to register pressure, the newly reloaded value could
be different from the previously fetched one, and you get inconsistent
results.

Only noticed this while hacking something else, no test case.
blk_max_low_pfn is initialized once at bootup by the block layer from
max_low_pfn. But max_low_pfn is not necessarily constant over the runtime of
the system when you consider memory hotplug. What could happen if that
someone adds memory later the block layer wouldn't get updated and then start
bouncing memory unnecessarily.
Also on 64bit blk_max_low_pfn actually isn't needed because it just disables
bouncing essentially and there is no highmem. And nobody can pass pfns >
max_low_pfn to the block layer, because those wouldn't have a struct page and
I suspect block layer wouldn't be very happy without that.
So set BLK_BOUNCE_HIGH to infinity (-1ULL) on 64bit. That avoids the problem
of having to update it on memory hotadd.
On 32bit I kept the same behaviour because at least on i386
memory hotadd only adds HIGHMEM, never lowmem.
BLK_BOUNCE_ANY is always set to infinity on both 32 and 64bit.

blk_rq_map_user adjusts bi_size of the last bio. It breaks the rule
that req->data_len (the true data length) is equal to sum(bio). It
broke the scsi command completion code.
commit e97a294ef6 was introduced to fix
the above issue. However, the partial completion code doesn't work
with it. The commit is also a layer violation (scsi mid-layer should
not know about the block layer's padding).
This patch moves the padding adjustment to blk_rq_map_sg (suggested by
James). The padding works like the drain buffer. This patch breaks the
rule that req->data_len is equal to sum(sg), however, the drain buffer
already broke it. So this patch just restores the rule that
req->data_len is equal to sub(bio) without breaking anything new.
Now when a low level driver needs padding, blk_rq_map_user and
blk_rq_map_user_iov guarantee there's enough room for padding.
blk_rq_map_sg can safely extend the last entry of a scatter list.
blk_rq_map_sg must extend the last entry of a scatter list only for a
request that got through bio_copy_user_iov. This patches introduces
new REQ_COPY_USER flag.

This patch enables bio_copy_user to take struct sg_iovec (renamed

bio_map_user uses bio_map_user_iov.

- adds sg_iovec array to struct bio_map_data
- adds __bio_copy_iov that copy data between bio and
sg_iovec. bio_copy_user_iov and bio_uncopy_user use it.

Vital Product Data (VPD) may be exposed by PCI devices in several
ways. It is generally unsafe to read this information through the
existing interfaces to user-land because of stateful interfaces.
This adds:
- abstract operations for VPD access (struct pci_vpd_ops)
- VPD state information in struct pci_dev (struct pci_vpd)
- an implementation of the VPD access method specified in PCI 2.2
(in access.c)
- a 'vpd' binary file in sysfs directories for PCI devices with VPD
operations defined
It adds a probe for PCI 2.2 VPD in pci_scan_device() and release of
VPD state in pci_release_dev().

use this generic version instead.
This version is based on powerpc, which seemed most up-to-date. The only

PCI Express ASPM defines a protocol for PCI Express components in the D0
state to reduce Link power by placing their Links into a low power state
and instructing the other end of the Link to do likewise. This
capability allows hardware-autonomous, dynamic Link power reduction
beyond what is achievable by software-only controlled power management.
However, The device should be configured by software appropriately.
Enabling ASPM will save power, but will introduce device latency.
This patch adds ASPM support in Linux. It introduces a global policy for
ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control
it. The interface can be used as a boot option too. Currently we have
below setting:
-default, BIOS default setting
-powersave, highest power saving mode, enable all available ASPM
state and clock power management
-performance, highest performance, disable ASPM and clock power
management
By default, the 'default' policy is used currently.
In my test, power difference between powersave mode and performance mode
is about 1.3w in a system with 3 PCIE links.
Note: some devices might not work well with aspm, either because chipset
issue or device issue. The patch provide API (pci_disable_link_state),
driver can disable ASPM for specific device.
