2014-03-24arm64: Support DMA_ATTR_WRITE_COMBINELaura Abbott1-2/+12

2014-03-24arm64: Implement custom mmap functions for dma mappingLaura Abbott1-0/+44
The current dma_ops do not specify an mmap function so maping falls back to the default implementation. There are at least two issues with using the default implementation: 1) The pgprot is always pgprot_noncached (strongly ordered) memory even with coherent operations 2) dma_common_mmap calls virt_to_page on the remapped non-coherent address which leads to invalid memory being mapped. Fix both these issue by implementing a custom mmap function which correctly accounts for remapped addresses and sets vm_pg_prot appropriately.

2014-03-23parisc: wire up sys_utimesHelge Deller2-2/+3
We seem to be nearly the only platform which does not provide the sys_utimes syscall. Adding it now makes our life much easier with userspace applications (like dietlibc and e2fsprogs) since we then behave like all other platforms too and don't need extra patches which are hard to get upstream anyway because we are not a mainstream architecture.

ASoC: Updates for v3.15 This is mostly a few additional fixes from Lars-Peter, a new driver and cleaning up a git failure with merging the Intel branch (combined with an xargs failure to pay attention to error codes). The history lists a bunch of additional commits for the branch but the content of those commits is actually present already but not recorded in history due to git failing. Unfortunately xargs is used in the merge script and it doesn't do a good job of noticing errors from the commands it invokes. # gpg: Signature made Thu 13 Mar 2014 14:25:44 GMT using RSA key ID 7EA229BD # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

ASoC: Updates for v3.15 Quite a busy release for ASoC this time, more on janitorial work than exciting new features but welcome nontheless: - Lots of cleanups from Takashi for enumerations; the original API for these was error prone so he's refactored lots of code to use more modern APIs which avoid issues. - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle. - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues. - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues. - DPCM support for Intel Haswell and Bay Trail platforms. - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC. # gpg: Signature made Wed 12 Mar 2014 23:05:45 GMT using RSA key ID 7EA229BD # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

2014-03-23rcuwalk: recheck mount_lock after mountpoint crossing attemptsAl Viro1-16/+13
We can get false negative from __lookup_mnt() if an unrelated vfsmount gets moved. In that case legitimize_mnt() is guaranteed to fail, and we will fall back to non-RCU walk... unless we end up running into a hard error on a filesystem object we wouldn't have reached if not for that false negative. IOW, delaying that check until the end of pathname resolution is wrong - we should recheck right after we attempt to cross the mountpoint. We don't need to recheck unless we see d_mountpoint() being true - in that case even if we have just raced with mount/umount, we can simply go on as if we'd come at the moment when the sucker wasn't a mountpoint; if we run into a hard error as the result, it was a legitimate outcome. __lookup_mnt() returning NULL is different in that respect, since it might've happened due to operation on completely unrelated mountpoint.

2014-03-23make prepend_name() work correctly when called with negative *buflenAl Viro1-2/+2
In all callchains leading to prepend_name(), the value left in *buflen is eventually discarded unused if prepend_name() has returned a negative. So we are free to do what prepend() does, and subtract from *buflen *before* checking for underflow (which turns into checking the sign of subtraction result, of course).

2014-03-23vfs: Don't let __fdget_pos() get FMODE_PATH filesEric Biggers1-15/+4
Commit bd2a31d522344 ("get rid of fget_light()") introduced the __fdget_pos() function, which returns the resulting file pointer and fdput flags combined in an 'unsigned long'. However, it also changed the behavior to return files with FMODE_PATH set, which shouldn't happen because read(), write(), lseek(), etc. aren't allowed on such files. This commit restores the old behavior. This regression actually had no effect on read() and write() since FMODE_READ and FMODE_WRITE are not set on file descriptors opened with O_PATH, but it did cause lseek() on a file descriptor opened with O_PATH to fail with ESPIPE rather than EBADF.

2014-03-21ASoC: mfld_machine: Convert to table based DAPM and control setupLars-Peter Clausen1-29/+20
Use table based setup to register the controls and DAPM widgets and routes. This on one hand makes the code a bit cleaner and on the other hand the board level DAPM elements get registered in the card's DAPM context rather than in the CODEC's DAPM context. The mfld_machine driver is a bit special in that it directly writes to one of the CODEC registers from one of the control handlers. Previous to this patch it was able to get a pointer to the CODEC from the control, since the control was registered with the CODEC. This won't be possible anymore once the control is registered with the card. Since there are already global variables in the driver accessed in the same function the patch adds a global variable that holds a pointer to the CODEC and uses that.
