tgafb: remove a redundant non-mono test in mono imageblit
There is a test in tgafb_mono_imageblit() for a colour image with a fall-back
to cfb_imageblit(). The test is not necessary as the only caller, which is
tgafb_imageblit(), checks it too and only invokes this function for monochrome
images. It looks like a left-over from before some changes to
tgafb_imageblit().

tgafb: fix an out-of-range shift in mono imageblit
The pixel mask calculation in tgafb_mono_imageblit() uses a variable
left-shift on a 32-bit data type by up to 32. Shifting by the width of a data
type or more produces an unpredictable result according to the C standard.
Rather than widening the data type this fix makes sure the count is between 0
and 31. The reason is not to penalise 32-bit platforms with operation on a
"long long" type for a marginal case that is meant not to happen (blitting an
image of a zero width).
The reason it has escaped for so long is the Alpha, being purely 64-bit, :-)
does not mask the shift out to 32 bits. This is a valid implementation --
producing the correct result certainly falls within "unpredictable behaviour".
It does trigger on MIPS though and it is the recent merge of the TC support
which only enabled the driver for use on anything other than the Alpha. For
MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as
it should be and the frame buffer is not updated.

fbcon: delay the start of the cursor timer until a con_switch()
As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular
cursor can still be seen blinking in the upper left part of the screen. It is
fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE,
KD_TEXT) call done by something in userspace, perhaps by X itself, while the
tty is still in graphics mode. And when the tty is in KD_TEXT mode, the
cursor timer is restarted.
Although this is a userspace problem, we can work around it by delaying the
restart of the cursor timer until an fbcon_switch() is called. In other
words, the cursor timer will not be restarted even if a KD_TEXT mode switch is
requested.

imxfb: fast read flag and nonstandard field configurable
The i.MX frame-buffer read operation should be faster for all configurations
then drawing each individual character again in response to scroll events.
The nonstandard fields allows to configure frame-buffer special options flags
for different display configurations by board specific initialization code.
One of such specific options is reversed order of pixels in each individual
byte. i.MX frame-buffer seems to be designed for big-endian use first. The
byte order is correctly configured for little-endian ordering, but if 1, 2 or
4 bits per pixel are used, pixels ordering is incompatible to Linux generic
frame-buffer drawing functions.
The patch "Allow generic BitBLT functions to work with swapped pixel order in
bytes" introduces required functionality into FBDEV core. The pixels ordering
selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE
and for each display configuration which requires it by flag
FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure.
This patch provides way for board specific code to select this option.

vt/vgacon: Check if screen resize request comes from userspace
Various console drivers are able to resize the screen via the con_resize()
hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware. However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.
To work around this problem, add an extra parameter to con_resize(). This
parameter is ignored by drivers except for vgacon. If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success. If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware. The
latter is the more correct behavior.
With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

nvidiafb: Add boot option to reverse i2c port assignment
There are a few nvidia hardware where the i2c port assignments are reversed,
i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c
port to the primary display. In most cases, if only 1 display is attached, or
if only 1 flatpanel and 1 analog display is attached, the port reversal is of
no consequence. However if 2 flatpanels are attached, it can cause display
problems.
There is no sane way of determining if the hardware reversed the i2c port
assignment, so the simplest fix is to add a boot/module option, "reverse_i2c
to explicitly reverse the i2c port.
This also restores i2c ordering back to the pre-2.6.22 state.

pxafb: Add support for other palette formats
This patch adds support for the other three palette formats possible with
the PXA LCD controller. This is required on boards where an LCD is connected
with all its 18 bits. With this patch, it's possible to use an 8-bit mode
with 18-bit palette entries. This used to be possible in 2.4 kernels but
disappeared in 2.6. With current kernels, you can only get wrong colours
out of an LCD connected this way.
Users can choose the palette format by doing something like this
in their board definition:
static struct pxafb_mach_info my_fb_info = {
[...]
.lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3,
.lccr4 = LCCR4_PAL_FOR_2,
