Jiri Slaby b694e52ebd PM / Hibernate: Really deprecate deprecated user ioctls
They were deprecated and removed from exported headers more than 2
years ago. Inform users about their removal in the future now.

(Switch cases needed to be reorderded for an easy fall through.)

And add an entry to feature-removal-schedule.

Rafael J. Wysocki 5a2eb8585f PM: Add facility for advanced testing of async suspend/resume
Add configuration switch CONFIG_PM_ADVANCED_DEBUG for compiling in
extra PM debugging/testing code allowing one to access some
PM-related attributes of devices from the user space via sysfs.

If CONFIG_PM_ADVANCED_DEBUG is set, add sysfs attribute power/async
for every device allowing the user space to access the device's
power.async_suspend flag and modify it, if desired.

Bjorn Helgaas 7bc5e3f2be x86/PCI: use host bridge _CRS info by default on 2008 and newer machines
The main benefit of using ACPI host bridge window information is that
we can do better resource allocation in systems with multiple host bridges,
e.g., http://bugzilla.kernel.org/show_bug.cgi?id=14183

Sometimes we need _CRS information even if we only have one host bridge,
e.g., https://bugs.launchpad.net/ubuntu/+source/linux/+bug/341681

Most of these systems are relatively new, so this patch turns on
"pci=use_crs" only on machines with a BIOS date of 2008 or newer.

Rafael J. Wysocki c39fae1416 PCI PM: Make it possible to force using INTx for PCIe PME signaling
Apparently, some machines may have problems with PCI run-time power
management if MSIs are used for the native PCIe PME signaling.  In
particular, on the MSI Wind U-100 PCIe PME interrupts are not
generated by a PCIe root port after a resume from suspend to RAM, if
the system wake-up was triggered by a PME from the device attached to
this port.  [It doesn't help to free the interrupt on suspend and
request it back on resume, even if that is done along with disabling
the MSI and re-enabling it, respectively.]  However, if INTx
interrupts are used for this purpose on the same machine, everything
works just fine.

For this reason, add a kernel command line switch allowing one to
request that MSIs be not used for the native PCIe PME signaling,
introduce a DMI table allowing us to blacklist machines that need
this switch to be set by default and put the MSI Wind U-100 into this
table.

Rafael J. Wysocki c7f486567c PCI PM: PCIe PME root port service driver
PCIe native PME detection mechanism is based on interrupts generated
by root ports or event collectors every time a PCIe device sends a
PME message upstream.

Once a PME message has been sent by an endpoint device and received
by its root port (or event collector in the case of root complex
integrated endpoints), the Requester ID from the message header is
registered in the root port's Root Status register.  At the same
time, the PME Status bit of the Root Status register is set to
indicate that there's a PME to handle.  If PCIe PME interrupt is
enabled for the root port, it generates an interrupt once the PME
Status has been set.  After receiving the interrupt, the kernel can
identify the PCIe device that generated the PME using the Requester
ID from the root port's Root Status register. [For details, see PCI
Express Base Specification, Rev. 2.0.]

Implement a driver for the PCIe PME root port service working in
accordance with the above description.

Based on a patch from Shaohua Li <shaohua.li@intel.com>.

Russell King d944d549aa ARM: allow alignment fault mode to be configured at kernel boot
Some glibc versions intentionally create lots of alignment faults in
their gconv code, which if not fixed up, results in segfaults during
boot.  This can prevent systems booting properly.

There is no clear hard-configurable default for this; the desired
default depends on the nature of the userspace which is going to be
booted.

So, provide a way for the alignment fault handler to be configured via
the kernel command line.

This patch also adds the v4l2 vc0301 driver for removal as it duplicates
functionality of the gspca_zc3xx driver, zc0301 only supports 2 USB-ID's
(because it only supports a limited set of sensors) wich are also

performance regression.  Unfortunately /proc/{pid}/status is used ps
command too and ps is one of most important component.  Because both to

If many process run, the ps performance is,

Thus, this patch revert it. Fortunately /proc/{pid}/task/{tid}/smaps
provide almost same information. we can use it.

Commit d899bf7b introduced two features:

 1) Add the annotattion of [thread stack: xxxx] mark to
    /proc/{pid}/task/{tid}/maps.
 2) Add StackUsage field to /proc/{pid}/status.

I only revert (2), because I haven't seen (1) cause regression.

Clemens Ladisch c5114a1cd6 hwmon: (k10temp) Blacklist more family 10h processors
The latest version of the Revision Guide for AMD Family 10h Processors
lists two more processor revisions which may be affected by erratum 319.
Change the blacklisting code to correctly detect those processors, by
implementing AMD's recommended algorithm.

Zhang Rui d7f0eea9e4 ACPI: introduce kernel parameter acpi_sleep=sci_force_enable
Introduce kernel parameter acpi_sleep=sci_force_enable

some laptop requires SCI_EN being set directly on resume,
or else they hung somewhere in the resume code path.

We already have a blacklist for these laptops but we still need
this option, especially when debugging some suspend/resume problems,
in case there are systems that need this workaround and are not yet
in the blacklist.
