2011-01-06kernel-doc: code reorganizationRandy Dunlap
Move 'main' code vs. subroutines around so that they are not so intermixed, for better readability/understanding (relative to Perl). It was messy to follow the primary flow of code execution with the code being mixed. Now the code begins with data initialization, followed by all subroutines, then ends with the main code execution. This is almost totally source code movement, with a few changes as needed for forward declarations.

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>

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.

2011-01-05ARM: PL011: add DMA burst threshold support for ST variantsRussell King

2011-01-05ARM: PL011: Add support for transmit DMARussell King
Add DMA engine support for transmit to the PL011 driver. Based on a patch from Linus Walliej, with the following changes: - remove RX DMA support. As PL011 doesn't give us receive timeout interrupts, we only get notified of received data when the RX DMA has completed. This rather sucks for interactive use of the TTY. - remove abuse of completions. Completions are supposed to be for events, not to tell what condition buffers are in. Replace it with a simple 'queued' bool. - fix locking - it is only safe to access the circular buffer with the port lock held. - only map the DMA buffer when required - if we're ever behind an IOMMU this helps keep IOMMU usage down, and also ensures that we're legal when we change the scatterlist entry length. - fix XON/XOFF sending - we must send XON/XOFF characters out as soon as possible - waiting for up to 4095 characters in the DMA buffer to be sent first is not acceptable. - fix XON/XOFF receive handling - we need to stop DMA when instructed to by the TTY layer, and restart it again when instructed to. There is a subtle problem here: we must not completely empty the circular buffer with DMA, otherwise we will not be notified of XON. - change the 'enable_dma' flag into a 'using DMA' flag, and track whether we can use TX DMA by whether the channel pointer is non-NULL. This gives us more control over whether we use DMA in the driver. - we don't need to have the TX DMA buffer continually allocated for each port - instead, allocate it when the port starts up, and free it when it's shut down. Update the 'using DMA' flag if we get the buffer, and adjust the TTY FIFO size appropriately. - if we're going to use PIO to send characters, use the existing IRQ based functionality rather than reimplementing it. This also ensures we call uart_write_wakeup() at the appropriate time, otherwise we'll stall. - use DMA engine helper functions for type safety. - fix init when built as a module - we can't have to initcall functions, so we must settle on one. This means we can eliminate the deferred DMA initialization. - there is no need to terminate transfers on a failed prep_slave_sg() call - nothing has been setup, so nothing needs to be terminated. This avoids a potential deadlock in the DMA engine code (tasklet->callback->failed prepare->terminate->tasklet_disable which then ends up waiting for the tasklet to finish running.) - Dan says that the submission callback should not return an error: | dma_submit_error() is something I should have removed after commit | a0587bcf "ioat1: move descriptor allocation from submit to prep" all | errors should be notified by prep failing to return a descriptor | handle. Negative dma_cookie_t values are only returned by the | dma_async_memcpy* calls which translate a prep failure into -ENOMEM. So remove the error handling at that point.

2011-01-05ARM: PL011: Ensure IRQs are disabled in UART interrupt handlerRussell King
