2014-06-02UBIFS: respect MS_SILENT mount flagDaniel Golle
When attempting to mount a non-ubifs formatted volume, lots of error messages (including a stack dump) are thrown to the kernel log even if the MS_SILENT mount flag is set. Fix this by introducing adding an additional state-variable in struct ubifs_info and suppress error messages in ubifs_read_node if MS_SILENT is set.

2014-06-02spi: rspi: Merge rspi_*_dma() into rspi_dma_transfer()Geert Uytterhoeven
rspi_send_dma() and rspi_send_receive_dma() are very similar. Consolidate into a single function rspi_dma_transfer(), and add missing checks for dmaengine_submit() failures. Both sg_table pointer parameters can be NULL, as RSPI supports TX-only mode, and unidirectional DMA transfers will also be needed later for Dual/Quad DMA support.

2014-06-02spi: rspi: Move RSPI-specific setup out of DMA routinesGeert Uytterhoeven
Refactor RSPI (on SH) DMA handling to make it reusable for other RSPI implementations: - Call the DMA routines after configuring the TX Mode bit and after calling rspi_receive_init(), so these RSPI-specific operations can be removed from the DMA routines, - Absorb rspi_transfer_out_in() into rspi_transfer_one().

2014-06-02spi: rspi: Use SPI core DMA mapping frameworkGeert Uytterhoeven

2014-06-02spi: rspi: SPI DMA core needs both RX and TX DMA to functionGeert Uytterhoeven
The SPI DMA core framework needs both RX and TX DMA to function. As a preparation for converting the driver to use this framework, fall back to PIO if no DMA channel or only one DMA channel is available. This affects only RSPI, which could do DMA transfers for TX-only before. RSPI-RZ and QSPI (at least for Single SPI Transfers) will need both RX and TX DMA anyway.

2014-06-02spi: rspi: Remove unneeded resource test in DMA setupGeert Uytterhoeven

2014-06-02spi: rspi: Extract rspi_pio_transfer()Geert Uytterhoeven
The various PIO loops are very similar. Consolidate into a single function rspi_pio_transfer().

2014-06-02spi: rspi: Use core SPI_MASTER_MUST_[RT]X handlingGeert Uytterhoeven
RSPI needs dummy transfers to generate the SPI clock on receive. RSPI-RZ and QSPI always do both transmit and receive. Use the SPI core SPI_MASTER_MUST_RX/SPI_MASTER_MUST_TX infrastructure instead of checking for the presence of buffers and providing dummy data ourselves (for PIO), or providing a dummy buffer (for DMA). rspi_receive_dma() now provides full duplex DMA transfers on RSPI, and is renamed to rspi_send_receive_dma(). As the SPI core will always provide a TX buffer, the logic to choose between DMA send and DMA send/receive in rspi_transfer_one() now has to check for the presence of an RX buffer. Likewise for the DMA availability tests in rspi_is_dma(). The buffer tests in qspi_transfer_one() are now always true, so they're removed.

2014-06-02spi: rspi: Remove unused 16-bit DMA supportGeert Uytterhoeven
The 16-bit DMA support doesn't fit well within the SPI core DMA framework, as it needs to manage its own double-sized temporary buffers, for handling the interleaved data. Remove it, as there is no in-tree board code that sets rspi_plat_data.dma_width_16bit. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Mark Brown <broonie@linaro.org>

Since commit 8449fd76deb9ac67a15a6fb8ead7bb4595d019d2 ("spi: rspi: Merge rspi_send_pio() and rspi_receive_pio()"), rspi_receive_init() is called for transmit-only transfers too, while this is not needed.

The conversion to a fixup table for Replacer model with ALC260 in commit 20f7d928 took the wrong widget NID for COEF setups. Namely, NID 0x1a should have been used instead of NID 0x20, which is the common node for all Realtek codecs but ALC260.

2014-06-02ext4: handle symlink properly with inline_dataZheng Liu
This commit tries to fix a bug that we can't read symlink properly with inline data feature when the length of symlink is greater than 60 bytes but less than extra space. The key issue is in ext4_inode_is_fast_symlink() that it doesn't check whether or not an inode has inline data. When the user creates a new symlink, an inode will be allocated with MAY_INLINE_DATA flag. Then symlink will be stored in ->i_block and extended attribute space. In the mean time, this inode is with inline data flag. After remounting it, ext4_inode_is_fast_symlink() function thinks that this inode is a fast symlink so that the data in ->i_block is copied to the user, and the data in extra space is trimmed. In fact this inode should be as a normal symlink. The following script can hit this bug. #!/bin/bash cd ${MNT} filename=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 rm -rf test mkdir test cd test echo "hello" >$filename ln -s $filename symlinkfile cd sudo umount /mnt/sda1 sudo mount -t ext4 /dev/sda1 /mnt/sda1 readlink /mnt/sda1/test/symlinkfile After applying this patch, it will break the assumption in e2fsck because the original implementation doesn't want to support symlink with inline data.

Linear store bandwidth is improved from 60GB/s to 125GB/s on Pitcairn. Unigine Heaven 3.0 sees an average improvement from 24.7 to 27.7 FPS on default settings at 1920x1200 resolution with vsync disabled.
