The following patch adds a dependancy on IDE=y && BLK_DEV_IDE=y
for the MPC8xx IDE driver.
The code is not modular at the moment (init called from platform setup code).

Some motherboards (such as the Asus P5V800-MX) ship a
PCI_DEVICE_ID_VIA_82C586_1 IDE controller alongside a VT8251 southbridge.
This southbridge is currently unrecognised in the via82cxxx IDE driver,
preventing those users from getting DMA access to disks.

When it detects a truncated report, hid-core emits a warning and then
processes the report as usual. This is good because it allows buggy
devices to still get data thru to userspace. However, the missing bytes of
the report should be cleared before processing, otherwise userspace will be
handed partially-uninitialized data.
This fixes Debian tracker bug #330487.

I haven't been very actively maintaining the input layer in past months,
mostly because of my lack of time to concentrate on that. For that reason,
I've decided to pass the maintainership of the Linux Input Layer to Dmitry
Torokhov, whom I trust to do the job very well.

Fix the following bugs in tg3_set_power_state():
1. Both WOL and ASF flags require switching to aux power.
2. Add a missing handshake with firmware to enable WOL.
3. Turn off the PHY if both WOL and ASF are disabled.
4. Add nvram arbitration before halting the firmware.
5. Fix tg3_setup_copper_phy() to switch to 100Mbps when
changing to low power state.
Update revision and date.

If the dual-port 5704 is configured as a single-port device with

tg3_find_5704_peer(). This fixes the problem by returning its
own pdev if the peer cannot be found.

Fix tg3_suspend() and tg3_resume() by clearing and setting the

Let's put my money where my mouth is. Smaller code is almost always
faster, if only because a single I$ miss ends up leaving a lot of cycles
to make up for. And system software - kernels in particular - are known
for taking more cache misses than most other kinds.
On my random config, this made the kernel about 10% smaller, and lmbench
seems to say that it's pretty uniformly faster too. Your milage may vary.

ERR_SEVERITY item is defined as a 8 bits item in SAL documentation
($B.2.1 rev december 2003), but as an u16 in sal.h.
This has the side effect that current code in mca.c may not call
ia64_sal_clear_state_info() upon receiving corrected platform errors
if there are bits set in the validation byte. Reported by Xavier Bru.

Some hardware does not support the PACKET command at all.
Other hardware supports ATAPI, but the driver does something nasty such
as calling BUG() when an ATAPI command is issued.
For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI.
Initial version contributed by Ben Collins.
The drawing function cfbfillrect does not work correctly when access is not
unsigned-long aligned. It manifests as extra lines of pixels that are not
complete drawn. Reversing the shift operator solves the problem, so I would
presume that this bug would manifest only on little endian machines. The
function cfbcopyarea may also have this bug.
Aligned access should present no problems.

In slow imageblit, the pixel value is shifted by a certain amount (dependent
on the bpp and endianness) for each iteration. This is inefficient. Better
do the shifting once before going into the loop.

Every framebuffer driver relies on the assumption that the set_par()
function of the driver is called before drawing functions and other
functions dependent on the hardware state are executed.
Whenever you switch from X to a framebuffer console for the very first
time, there is a chance that a broken X system has _not_ set the mode to
KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and
several other functions before a set_par() is executed. This is believed
to be not a bug of linux but a bug of X/xdm. At least some X releases used
by SuSE and Debian show this behaviour.
There was a 2nd case, but that has been fixed by Antonino Daplas on
10-dec-2005.
This patch allows drivers to set a flag to inform fbcon_switch() that they
prefer a set_par() call on every console switch, working around the
problems caused by the broken X releases.
The flag will be used by the next release of cyblafb and might help other
drivers that assume a hardware state different to the one used by X.
As the default behaviour does not change, this patch should be acceptable
to everybody.
