USB: teach "devices" file about Wireless and SuperSpeed USB

2011-08-01T20:54:44+00:00

commit 834e2312e7a384877a876b0d34dffc3046c96bcb upstream.

USB: teach "devices" file about Wireless and SuperSpeed USB

The /sys/kernel/debug/usb/devices file doesn't know about Wireless or
SuperSpeed USB.  This patch (as1416b) teaches it, and updates the
Documentation/usb/proc_sub_info.txt file accordingly.

Remove the old V4L1 v4lgrab.c file

2011-08-01T20:54:41+00:00

[ upstream commit 55fe25b418640fad04190103274841b2c907bacd ]

This example file uses the old V4L1 API. It also doesn't use libv4l.
So, it is completely obsolete. A good example already exists at
v4l-utils (v4l2grab.c):
	http://git.linuxtv.org/v4l-utils.git

[AK: included in 2.6.35 because v4lgrab doesn't build without 
the host's linux/videodev.h]

kbuild: Fix passing -Wno-* options to gcc 4.4+

2011-08-01T20:54:33+00:00

[ upstream commit 8417da6f2128008c431c7d130af6cd3d9079922e ]

Starting with 4.4, gcc will happily accept -Wno- in the
cc-option test and complain later when compiling a file that has some
other warning. This rather unexpected behavior is intentional as per
http://gcc.gnu.org/PR28322, so work around it by testing for support of
the opposite option (without the no-). Introduce a new Makefile function
cc-disable-warning that does this and update two uses of cc-option in
the toplevel Makefile.

PM / Hibernate: Make default image size depend on total RAM size

2011-03-31T18:58:51+00:00

[ upstream commit ac5c24ec1e983313ef0015258fba6f630e54e7cf ]

The default hibernation image size is currently hard coded and euqal
to 500 MB, which is not a reasonable default on many contemporary
systems.  Make it equal 2/5 of the total RAM size (this is slightly
below the maximum, i.e. 1/2 of the total RAM size, and seems to be
generally suitable).

x86: Add IRQ_TIME_ACCOUNTING

2011-03-31T18:58:00+00:00

Commit: e82b8e4ea4f3dffe6e7939f90e78da675fcc450e upstream

This patch adds IRQ_TIME_ACCOUNTING option on x86 and runtime enables it
when TSC is enabled.

This change just enables fine grained irq time accounting, isn't used yet.
Following patches use it for different purposes.

Input: i8042 - introduce 'notimeout' blacklist for Dell Vostro V13

2011-02-06T19:03:53+00:00

i8042 controller present in Dell Vostro V13 errorneously signals spurious
timeouts.

Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts
and apply this quirk automatically for Dell Vostro V13, based on DMI match.

In addition to that, this machine also needs to be added to nomux blacklist.

PM / Runtime: Fix pm_runtime_suspended()

2011-02-06T19:03:41+00:00

commit f08f5a0add20834d3f3d876dfe08005a5df656db upstream.

There are some situations (e.g. in __pm_generic_call()), where
pm_runtime_suspended() is used to decide whether or not to execute
a device's (system) ->suspend() callback.  The callback is not
executed if pm_runtime_suspended() returns true, but it does so
for devices that don't even support runtime PM, because the
power.disable_depth device field is ignored by it.  This leads to
problems (i.e. devices are not suspened when they should), so rework
pm_runtime_suspended() so that it returns false if the device's
power.disable_depth field is different from zero.
