the SMP load-balancer uses the boot-time migration-cost estimation
code to attempt to improve the quality of balancing. The reason for
this code is that the discrete priority queues do not preserve
the order of scheduling accurately, so the load-balancer skips
tasks that were running on a CPU 'recently'.
this code is fundamental fragile: the boot-time migration cost detector
doesnt really work on systems that had large L3 caches, it caused boot
delays on large systems and the whole cache-hot concept made the
balancing code pretty undeterministic as well.
(and hey, i wrote most of it, so i can say it out loud that it sucks ;-)
under CFS the same purpose of cache affinity can be achieved without
any special cache-hot special-case: tasks are sorted in the 'timeline'
tree and the SMP balancer picks tasks from the left side of the
tree, thus the most cache-cold task is balanced automatically.

There are some devices (for example Dell Multimedia Keyboard SK-8135) that have
a volume control knob which generates relative events instead of absolute.
hid-input maps them to ABS_VOLUME. HUT pages don't restrict volume to absolute
values.
Adding REL_VOLUME doesn't seem feasible, nothing knows how to handle it. This
patch translates relative ABS_VOLUME events into appropriate number of series
of VOLUME_UP or VOLUME_DOWN events respectively, so that userspace sees the
correct values in the end.

This keyboard has wireless mouse which has left, middle, right buttons and
2-dimensional scrolling wheel. Unfornetuly, this wheel reports side scrolling
events and 11 or 12 button events at the same time.
I've wrote a patch to fix this mapping. I'm not sure if this mapping is proper
for buttons, because , for example, there is no entry for "burn cd" in input.h.
The patch also supress 11 and 12 button events from mouse when you scroll the
wheel left and right. With this patch, only side scrolling events are
reported. (This mouse has only 4 buttons and 2D wheel. There is no such
buttons like 11 and 12.)

Lately there have been quite a lot of bug reports against broken devices
which require us to fix their report descriptor in the runtime, before it
is passed to the HID parser. Those devices have eaten quite an amount of
our quirks space, which isn't particularly necessary - the quirks are not
needed after the report descriptor is parsed, and they just consume bits.
Therefore this patch separates the quirks for report descriptor fixup, and
moves their handling into separate code. The quirks are then forgotten as
soon as the report descriptor has been parsed.
Module parameter 'rdesc_quirks' is introduced to be able to modify these
quirks in runtime in a similar way to 'quirks' parameter for ordinary HID
quirks.

Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from
consumer page (reserved in HUT 1.12) for back and more keys. It also emits
a few usages from LOGIVENDOR page, which need adding.
Also, this device has broken report descriptor - the reported maximum is too
low - it doesn't contain the range for 'back' and 'more' keys, so we need to
bump it up before the report descriptor is being parsed.
Besides all this, it also requires NOGET quirk.
This patch does so.

When comparing usb vs ps2 / testing the keycodes generated for the easy access
keys on my trust (microsoft compatible) keyboard. I noticed the search key
generated the keycode for find when connected through USB. This lead me to
check the consumer page mappings in hid-input.c . And it turns out the the
mapping for ID 0x221 deviates from the HUT standard document:
http://www.usb.org/developers/devclass_docs/Hut1_12.pdf
Currently it is incorrectly mapped to find, whereas it should be mapped to
search. I also added missing bindings for ID 0x21f, the real find and for
0x222, goto.

Microsoft SideWinder GameVoice driver is a trivial device with a few buttons
(0x09 HID usage) and an audio connector, which just forwards the audio input
into oridinary sound card present in the computer.
Despite this fact, the only interface of this device reports itself as a
Telephony/Headset type of HID device. This is apparently incorrect - the device
itself doesn't provide any audio/telephony functionality. This is achieved in
userland application which only needs to receive the button events from the HID
driver.
This patch establishes a new quirk which forces hid-input to claim a device it
will otherwise leave untouched.

The rx copybreak part is straightforward.
The align field in struct rtl_cfg_info is related to the alignment
requirements of the DMA operation. Its value is set at 2 to limit the
scale of possible regression but my old v1.21 8169 datasheet claims a
8 bytes requirements (which never appeared in the driver, of course)
and the 8101/8168 go with a plain 8 bytes alignment.

- new identifier for the 8110SCe
- the PCI latency timer is set unconditionally. This part is identical
in Realtek's r8168 (8.001.00) and r8101 (1.001.00)
- initialization of the cache line size register is for the 8169s only
- more magic in rtl_hw_start_8169
- it is not possible to factor out the setting of the the irq event mask
with the 8168 and the 8101 any more. Pushed it into the hw_start handler.
- rtl_set_rx_tx_config_registers() and write to the ChipCmd register are
issued identically for the whole 8169/8110 family: the 8110SCd/8110SCe
are handled the same way
- work around for AMD platform.
Some registers definitions in Realtek's driver are let aside for later.
