ddf02886cb PCI: iova RB tree setup tweak
The following patch merges two functions into one allowing for a 3%
reduction in overhead in locating, allocating and inserting pages for
use in IOMMU operations.

Its a bit of a eye-crosser so I welcome any RB-tree / MM experts to take
a look.  It works by re-using some of the information gathered in the
search for the pages to use in setting up the IOTLB's in the insertion
of the iova structure into the RB tree.

842de40d93 PCI: add generic pci_enable_resources()
Each architecture has its own pcibios_enable_resources() implementation.
These differ in many minor ways that have nothing to do with actual
architectural differences.  Follow-on patches will make most arches
use this generic version instead.

This version is based on powerpc, which seemed most up-to-date.  The only
functional difference from the x86 version is that this uses "!r->parent"
to check for resource collisions instead of "!r->start && r->end".

7d715a6c1a 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.

cb3576fa34 PCI: Include PCI domain in PCI bus names on x86/x86_64
The PCI bus names included in /proc/iomem and /proc/ioports are
of the form 'PCI Bus #XX' where XX is the bus number.  This patch
changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain
number and YY is the bus number.  For example, PCI bus 14 in
domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'.
This change makes the naming consistent with other architectures
such as ia64 where multiple PCI domain support has been around
longer.

This function was obviously never being used since early 2.5 days as any

1ba6ab11d8 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.

95247b57ed PCI: clean up search.c a lot
This cleans up the search.c file, now using the pci list of devices that
are created for the driver core, instead of relying on our separate list
of devices.  It's better to use the functions already created for this
kind of thing, instead of rolling our own all the time.

This work is done in anticipation of getting rid of that second list of
pci devices all together.

And it ends up saving code, always a nice benefit.

This also removes one compiler warning for when CONFIG_PCI_LEGACY is
enabled as we no longer internally use the deprecated functions anymore.

de224c309b [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:

477035c2ab [CRYPTO] tcrypt: Group common speed templates
Some crypto ciphers which are impleneted support similar key sizes
(16,24 & 32 byte). They can be grouped together and use a common
templatte instead of their own which contains the same data.

78f8b3a240 [CRYPTO] sha512: Rename sha512 to sha512_generic
Rename sha512 to sha512_generic and add a MODULE_ALIAS for sha512
so all sha512 implementations can be loaded automatically.

Keep the broken tabs so git recognizes this as a rename.

604973f1fe [CRYPTO] s390: Generic sha_update and sha_final
The sha_{update|final} functions are similar for every sha variant.
Since that is error-prone and redundant replace these functions by
a shared generic implementation for s390.
