ptrace: compat_ptrace_request siginfo
This adds support for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO in
compat_ptrace_request. It relies on existing arch definitions for
copy_siginfo_to_user32 and copy_siginfo_from_user32.
On powerpc, this fixes a longstanding regression of 32-bit ptrace
calls on 64-bit kernels vs native calls (64-bit calls or 32-bit
kernels). This can be seen in a 32-bit call using PTRACE_GETSIGINFO
to examine e.g. siginfo_t.si_addr from a signal that sets it.
(This was broken as of 2.6.24 and, I presume, many or all prior versions.)

Fix RCU list iterator use of 'rcu_dereference()'
The RCU iterators used 'rcu_dereference()' on an already-fetched RCU
pointer value, which defeats the whole point of the exercise.
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.

It seems that hrtimer_run_queues() is calling hrtimer_get_softirq_time() more
often than it needs to. This can cause frequent contention on systems with
large numbers of processors/cores.
With this patch, hrtimer_run_queues only calls hrtimer_get_softirq_time() if
there is a pending timer in one of the hrtimer bases, and only once.
This also combines hrtimer_run_queues() and the inline run_hrtimer_queue()

PCI: Hotplug: fakephp: Return success, not ENODEV, when bus rescan is triggered
The 'power' attribute of the fakephp driver originally only let one turn a
slot off. If one tried to turn a slot on (echo 1 > .../power), it would
return ENODEV, as fakephp did not support this function.
An old (pre-git) patch changed this:
2004/11/11 16:33:31-08:00 jdittmer
[PATCH] fakephp: add pci bus rescan ability
http://article.gmane.org/gmane.linux.kernel/251183
Now writing "1" to the power attribute has the effect of triggering a bus
rescan, but it still returns ENODEV, probably an oversight in the above
patch.
Using the BusyBox echo will not produce an error message, but will
trigger *two* bus rescans (and return an exit code of 1):
~ # strace echo -n 1 > /sys/bus/pci/slots/0000:00:00.0/power
...
write(1, "1", 1) = -1 ENODEV (No such device)
write(1, "1", 1) = -1 ENODEV (No such device)
exit(1) = ?
Using cp gives a write error, even though the write did happen and a rescan
was triggered:
~ # echo -n 1 > tmp ; cp tmp /sys/bus/pci/slots/0000:00:00.0/power
cp: Write Error: No such device
It seems much better to return success instead of failure. The actual
status of the bus rescan is hard to return. It happens asynchronously in a
work thread, so the sysfs store functions returns before any status is
ready (the whole point of the work queue). And even if it didn't do this,
the rescan doesn't have any clear status to return.

PCI: add PCI Express ASPM support
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.

PCI: remove initial bios sort of PCI devices on x86
We currently keep 2 lists of PCI devices in the system, one in the
driver core, and one all on its own. This second list is sorted at boot
time, in "BIOS" order, to try to remain compatible with older kernels
(2.2 and earlier days). There was also a "nosort" option to turn this
sorting off, to remain compatible with even older kernel versions, but
that just ends up being what we have been doing from 2.5 days...
Unfortunately, the second list of devices is not really ever used to
determine the probing order of PCI devices or drivers[1]. That is done
using the driver core list instead. This change happened back in the
early 2.5 days.
Relying on BIOS ording for the binding of drivers to specific device
names is problematic for many reasons, and userspace tools like udev
exist to properly name devices in a persistant manner if that is needed,
no reliance on the BIOS is needed.
Matt Domsch and others at Dell noticed this back in 2006, and added a
boot option to sort the PCI device lists (both of them) in a
breadth-first manner to help remain compatible with the 2.4 order, if
needed for any reason. This option is not going away, as some systems
rely on them.
This patch removes the sorting of the internal PCI device list in "BIOS"
mode, as it's not needed at all anymore, and hasn't for many years.
I've also removed the PCI flags for this from some other arches that for
some reason defined them, but never used them.
This should not change the ordering of any drivers or device probing.
[1] The old-style pci_get_device and pci_find_device() still used this
sorting order, but there are very few drivers that use these functions,
as they are deprecated for use in this manner. If for some reason, a
driver rely on the order and uses these functions, the breadth-first
boot option will resolve any problem.

Thanks for the suggestion, the init() is replaced with
<algorithm name>_mod_init ()
and fini () is replaced with <algorithm name>_mod_fini.

The third test vector of ECB-XTEA-ENC fails for me all other
are fine. I could not find a RFC or something else where they
are defined. The test vector has not been modified since git
started recording histrory. The implementation is very close
(not to say equal) to what is available as Public Domain (they
recommend 64 rounds and the in kernel uses 32). Therefore I
belive that there is typo somewhere and tcrypt reported always
*fail* instead of *okey*.
This patch replaces input + result of the third test vector with
result + input from the third decryption vector. The key is the
same, the other three test vectors are also the reverse.

[CRYPTO] tcrypt: Shrink the tcrypt module
Currently the tcrypt module is about 2 MiB on x86-32. The
main reason for the huge size is the data segment which contains
all the test vectors for each algorithm. The test vectors are
staticly allocated in an array and the size of the array has been
drastically increased by the merge of the Salsa20 test vectors.
With a hint from Benedigt Spranger I found a way how I could
convert those fixed-length arrays to strings which are flexible
in size. VIM and regex were also very helpfull :)
So, I am talking about a shrinking of ~97% on x86-32:
