2011-01-06fbdev: modedb: Add a new mode for 864x480 TAAL panels.Mayuresh Janorkar
This adds a new entry to the modedb for 864x480 TAAL panels, the default configuration for many OMAP boards. This enables omapfb to make use of the standard mode parsing. Signed-off-by: Mayuresh Janorkar <mayur@ti.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-01-06drivers/video/i810/i810-i2c.c: fix i2c bus handlingStefani Seibold
These patch fix a longstanding bug in the i810 frame buffer driver. The handling of the i2c bus is wrong: A 1 bit should not written to the i2c, these will be done by switch the i2c to input. Driving an 1 bit active is against the i2c spec. An active driven of a 1 bit will result in very strange error, depending which side is the more powerful one. In my case it depends on the temperature of the Display-Controller-EEprom: With an cold eprom a got the correct EDID datas, with a warm one some of the 1 bits was 0 :-( The same bug is also in the intelfb driver in the file drivers/video/intelfb/intelfb_i2c.c. The functions intelfb_gpio_setscl() and intelfb_gpio_setsda() do drive the 1 bit active to the i2c bus. But since i have no card which is used by the intelfb driver i cannot fix it.

2011-01-06video: Fix the HGA framebuffer driverBrent Cook
Resurrected some old hardware and fixed up the hgafb driver to work again. Only tested with fbcon, since most fbdev-based software appears to only support 12bpp and up. It does not appear that this driver has worked for at least the entire 2.6.x series, perhaps since 2002. Hercules graphics hardware uses packed pixels horizontally, but rows are not linear. In other words, the pixels are not packed vertically. This means that custom imageblit, fillrect and copyarea need to be written specific to the hardware. * Removed the experimental acceleration option, since it is required for the hardware to work. * Fixed imageblit to work with fb_image's wider than 8 pixels. * Updated configuration text (HGA hardware is from 1984) Signed-off-by: Brent Cook <busterb@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2011-01-06fbdev: sh_mobile_lcdcfb: Enable 32 bpp and 24 bpp supportMagnus Damm
This patch extends the LCDC driver with 24 bpp and 32 bpp support. These modes have been kept disabled earlier due to dependencies between the potential two LCDC channels that are exported as two separate framebuffer devices. The dependency boils down to a byte swap register that is shared between multiple channels. With this patch applied all single channel LCDC hardware can chose freely from 16, 24 and 32 bpp. Dual channel LCDC must stick to the same setup for both channels. Without this patch only 16 bpp is fully supported. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

With cmwq, there's no reason for radeon to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Because radeon_driver_irq_uninstall_kms() may be called from unsleepable context, the work items can't be flushed from there. Instead, init and flush from radeon_irq_kms_init/fini().

The bios connector table reflects this and is technically correct, however, we drop the DVI connector here since xrandr has no concept of encoders (only crtcs and connectors) and will try and drive both connectors with different crtcs which isn't possible on the hardware side and leaves no crtcs for LVDS or VGA.

2011-01-05af_unix: Avoid socket->sk NULL OOPS in stream connect security hooks.David S. Miller
unix_release() can asynchornously set socket->sk to NULL, and it does so without holding the unix_state_lock() on "other" during stream connects. However, the reverse mapping, sk->sk_socket, is only transitioned to NULL under the unix_state_lock(). Therefore make the security hooks follow the reverse mapping instead of the forward mapping.

2011-01-05net_sched: pfifo_head_drop problemEric Dumazet
commit 57dbb2d83d100ea (sched: add head drop fifo queue) introduced pfifo_head_drop, and broke the invariant that sch->bstats.bytes and sch->bstats.packets are COUNTER (increasing counters only) This can break estimators because est_timer() handles unsigned deltas only. A decreasing counter can then give a huge unsigned delta. My mid term suggestion would be to change things so that sch->bstats.bytes and sch->bstats.packets are incremented in dequeue() only, not at enqueue() time. We also could add drop_bytes/drop_packets and provide estimations of drop rates. It would be more sensible anyway for very low speeds, and big bursts. Right now, if we drop packets, they still are accounted in byte/packets abolute counters and rate estimators. Before this mid term change, this patch makes pfifo_head_drop behavior similar to other qdiscs in case of drops : Dont decrement sch->bstats.bytes and sch->bstats.packets Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Hagen Paul Pfeifer <hagen@jauu.net> Signed-off-by: David S.
