ieee1394: csr1212: proper refcounting

At least since nodemgr got rid of coarse global locking, accesses to
struct csr1212_keyval's reference counter should be atomic and coupled
with proper barriers.  Also, calls to csr1212_keep_keyval(kv) should
occur before kv is being used.

(We probably should convert refcnt to struct kref, but how to keep
csr1212_destroy_keyval's implementation non-recursively then?)

ieee1394: nodemgr: fix leak of struct csr1212_keyval

csr1212_keep_keyval(kv) in nodemgr_process_root_directory was
unbalanced if ne->vendor_name_kv already exists.  This happens for
example if eth1394 or raw1394 modify the local config ROM and it is
parsed again.

As a bonus, the attempt to add the vendor_name_kv sysfs attribute
when it already exists is now fixed for good.

ieee1394: Fix kthread stopping in nodemgr_host_thread

The nodemgr host thread can exit on its own even when kthread_should_stop
is not true, on receiving a signal (might never happen in practice, as
it ignores signals). But considering kthread_stop() must not be mixed with
kthreads that can exit on their own, I think changing the code like this
is clearer. This change means the thread can cut its sleep short when
receive a signal but looking at the code around, that sounds okay (and
again, it might never actually recieve a signal in practice).

time: introduce xtime_seconds

tv_sec portion of the GTOD time. But the data structure "xtime", which
is updated by every timer/scheduler tick, already offers HZ granularity
time.

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.

Regression potential: Present but low

fbdev: copyarea function taught to fully support swapped pixel order in byte

This correct case, when source and destination X coordinates difference is n
multiple of pixels in byte.  This is probably rare case, but this case should
supported for completeness.

Reorganization of FB_READL and FB_WRITEL calls results in code size decrease
for normal build without swapping support and size with support enabled is
reasonable too.

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.

Radeonfb Xpress 200M RC410 support

Make radeonfb work ith the 200m Xpress RC410.  In my tests it was terribly
unstable and would freeze until I set a refresh rate in the kernel argument
to 75.

e.g video=radeonfb:1280x800@75

Now it is rock solid.

ps3: Fix black and white stripes

Fix the black and white stripes issue with WUXGA monitor via HDMI.

It seems that when we use a VESA resolution from boot up, the AV settings
driver could not be initialized correctly.  In that case we need a dummy
packet before VESA setting.

fbdev: Support for byte-reversed framebuffer formats

Allow generic frame-buffer code to correctly write texts and blit images for
1, 2 and 4 bit per pixel frame-buffer organizations when pixels in bytes are
organized to in opposite order than bytes in long type.

Overhead should be reasonable.  If option is not selected, than compiler
should eliminate completely all overhead.

The feature is disabled at compile time if CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is
not set.

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.

fbdev: find mode with the highest/safest refresh rate in fb_find_mode()

Currently, if the refresh rate is not specified, fb_find_mode() returns the
first known video mode with the requested resolution, which provides no
guarantees wrt the refresh rate.  Change this so that the mode with the
highest refresh rate is returned when the driver provides a custom video mode
database and the monitor limits, and a mode with the safe 60 Hz refresh rate
otherwise.
