2014-05-05tty: Fix low_latency BUGPeter Hurley
commit a9c3f68f3cd8d55f809fbdb0c138ed061ea1bd25 upstream. The user-settable knob, low_latency, has been the source of several BUG reports which stem from flush_to_ldisc() running in interrupt context. Since 3.12, which added several sleeping locks (termios_rwsem and buf->lock) to the input processing path, the frequency of these BUG reports has increased. Note that changes in 3.12 did not introduce this regression; sleeping locks were first added to the input processing path with the removal of the BKL from N_TTY in commit a88a69c91256418c5907c2f1f8a0ec0a36f9e6cc, 'n_tty: Fix loss of echoed characters and remove bkl from n_tty' and later in commit 38db89799bdf11625a831c5af33938dcb11908b6, 'tty: throttling race fix'. Since those changes, executing flush_to_ldisc() in interrupt_context (ie, low_latency set), is unsafe. However, since most devices do not validate if the low_latency setting is appropriate for the context (process or interrupt) in which they receive data, some reports are due to misconfiguration. Further, serial dma devices for which dma fails, resort to interrupt receiving as a backup without resetting low_latency. Historically, low_latency was used to force wake-up the reading process rather than wait for the next scheduler tick. The effect was to trim multiple milliseconds of latency from when the process would receive new data. Recent tests [1] have shown that the reading process now receives data with only 10's of microseconds latency without low_latency set. Remove the low_latency rx steering from tty_flip_buffer_push(); however, leave the knob as an optional hint to drivers that can tune their rx fifos and such like. Cleanup stale code comments regarding low_latency.

commit 2d1f7af3d60dd09794e0738a915d272c6c27abc5 upstream.

The bcm63xx_udc driver was not updated, and as a result, causes the following build error to pop up: CC drivers/usb/gadget/u_ether.o drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_write': drivers/usb/gadget/bcm63xx_udc.c:642:24: error: called object '0' is not a function drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_reset_channel': drivers/usb/gadget/bcm63xx_udc.c:698:46: error: called object '0' is not a function drivers/usb/gadget/bcm63xx_udc.c:700:49: error: called object '0' is not a function Fix this by updating usb_dmac_{read,write}l and usb_dmas_{read,write}l to take an extra channel argument, and use the channel width (ENETDMA_CHAN_WIDTH) to offset the register we want to access, hence doing again what the macro implicitely did for us.

2013-11-25usb: gadget: fix pxa25x compilation problemsLinus Walleij
In commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" we removed the implicit inclusion of <mach/gpio.h> from <linux/gpio.h>. The pxa25x_udc was not using that, but it was relying on <linux/gpio.h> to implictly include <mach/gpio.h> which in turn implicitly included <mach/hardware.h>, which was needed for the driver to compile. Fix this up by explicitly including the necessary <mach/hardware.h> header.

2013-11-25usb: gadget: s3c-hsotg: fix disconnect handlingRobert Baldyga
This patch moves s3c_hsotg_disconnect function call from USBSusp interrupt handler to SET_ADDRESS request handler. It's because disconnected state can't be detected directly, because this hardware doesn't support Disconnected interrupt for device mode. For both Suspend and Disconnect events there is one interrupt USBSusp, but calling s3c_hsotg_disconnect from this interrupt handler causes config reset in composite layer, which is not undesirable for Suspended state. For this reason s3c_hsotg_disconnect is called from SET_ADDRESS request handler, which occurs always after disconnection, so we do disconnect immediately before we are connected again. It's probably only way we can do handle disconnection correctly.

2013-11-13Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-10-31DMA-API: usb: use dma_set_coherent_mask()Russell King
The correct way for a driver to specify the coherent DMA mask is not to directly access the field in the struct device, but to use dma_set_coherent_mask(). Only arch and bus code should access this member directly. Convert all direct write accesses to using the correct API.
