handle_pte_fault uses pte_present, pte_none and pte_file to find out
the type of a pte. That is done without holding the page table lock.
This clashes with the way how ptep_clear_flush removes active page
table entries from the system. First the ipte instruction is used
to invalidate the pte and remove all plt entries for the page. The
ipte sets the hardware invalid bit without changing any other bit.
After the ipte finished the pte is cleared. A concurrent fault can
observe the the previously valid pte with the invalid bit set. With
the current encoding of the different pte types an invalidated
read-only pte can be misinterpreted as a swap-pte.

For Hummingbird PCI controllers, we should create the root
PCI memory space resource as the full 4GB area, and then
allocate the IOMMU DMA translation window out of there.
The old code just assumed that the IOMMU DMA translation base
to the top of the 4GB area was unusable. This is not true on
many systems such as SB100 and SB150, where the IOMMU DMA
translation window sits at 0xc0000000->0xdfffffff.
So what would happen is that any device mapped by the firmware
at the top section 0xe0000000->0xffffffff would get remapped
by Linux somewhere else leading to all kinds of problems and
boot failures.
While we're here, report more cases of OBP resource assignment
conflicts. The only truly valid ones are ROM resource conflicts.

increase to the Sierra driver and adds support for modem status line
control (e.g. the DTR line). This patch also updates the current sierra.c
driver so that it supports both 3-port Sierra devices and 1-port legacy
devices and removes Sierra's references in other related files (Kconfig and

Adds support for dance pads to the xpad driver. Dance pads require the
d-pad to be mapped to four buttons instead of two axes, so that
combinations of up/down and left/right can be hit simultaneously.
Known dance pads are detected, and there is a module parameter added
to default unknown xpad devices to map the d-pad to buttons if this is
desired. (dpad_to_buttons). Minor modifications were made to port the
changes in the original patch to a newer kernel version.
This patch was originally from Dominic Cerquetti originally written
for kernel 2.6.11.4, with minor modifications (API changes for USB,
spelling fixes to the documentation added in the original patch) made
to apply to the current kernel. I have modified Dominic's original
patch per some suggestions from Dmitry Torokhov. (There was nothing
in the patch format description about multiple From: lines, so I
haven't added myself.)

extract() and implement() have brain damaged attempts to handle 32-bit wide
"fields".
The problem is the index math in the original code didn't clear all the
relevant bits. (offset >> 5) only compensated for 32-bit index. We need
(offset >> 6) if we want to use 64-bit loads.
But it was also wrong in that it tried to use quasi-aligned loads. Ie
"report" was only incremented in multiples of 4 bytes and then the offset
was masked off for values greater than 4 bytes. The right way is to
pretend "report" points at a byte array. And offset is then only minor
adjustment for < 8 bits of offset. "n" (field width) can then be as big as
24 (assuming 32-bit loads) since "offset" will never be bigger than 7.
If someone needs either function to handle more than 24-bits, please
document why - point at a specification or specific USB hid device - in
comments in the code.
extract/implement() are also an eyesore to read. Please banish whoever
wrote it to read CodingStyle 3 times in a row to a classroom full of 1st
graders armed with rubberbands. Or just flame them. Whatever. Globbing
all the code together on two lines does NOT make it faster and is Just
Wrong.

When working on the mcs7830, I noticed the need for a mutex in its

in the asix driver in the respective functions.
This introduces a mutex in the common usbnet driver and uses it
from the two hardware specific drivers.

This adds generic support for the ethtool commands get_settings,
set_settings, get_link and nway_reset to usbnet. These are now
implemented using mii functions when a low-level driver supports
mdio_read/mdio_write and does not override the usbnet ethtool
commands with its own.
Currently, this applies to the asix and the mcs7830 drivers.

This driver adds support for the DeLOCK USB ethernet adapter
and potentially others based on the MosChip MCS7830 chip.
It is based on the usbnet and asix drivers as well as the
original device driver provided by MosChip, which in turn
was based on the usbnet driver.
It has been tested successfully on an OHCI, but interestingly
there seems to be a problem with the mcs7830 when connected to
the ICH6/EHCI in my thinkpad: it keeps receiving lots of
broken packets in the RX interrupt. The problem goes away when
I'm using an active USB hub, so I assume it's not related to
the device driver, but rather to the hardware.
