2014-03-25xen-netback: Proper printf format for ptrdiff_t is 't'.David S. Miller
This fixes: drivers/net/xen-netback/netback.c: In function ‘xenvif_tx_dealloc_action’: drivers/net/xen-netback/netback.c:1573:8: warning: format ‘%x’ expects argument of type ‘unsigned int’, but argument 3 has type ‘long int’ [-Wformat=] Signed-off-by: David S. Miller <davem@davemloft.net>
2014-03-25Revert "xen-netback: Aggregate TX unmap operations"Zoltan Kiss
This reverts commit e9275f5e2df1b2098a8cc405d87b88b9affd73e6. This commit is the last in the netback grant mapping series, and it tries to do more aggressive aggreagtion of unmap operations. However practical use showed almost no positive effect, whilst with certain frontends it causes significant performance regression.

2014-03-25Merge tag 'asoc-v3.15' into asoc-nextMark Brown
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>"
2014-03-25spi: Do not require a completionMark Brown
There is no real reason why we require transfers to have a completion and the only user of the completion now checks to see if one has been provided before using it so stop enforcing this. This makes it more convenient for drivers to chain multiple asynchronous transfers together. Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-25ata: add new-style AHCI platform driver for DaVinci DA850 AHCI controllerBartlomiej Zolnierkiewicz
Add the new ahci_da850 host driver. Platform changes needed to make DaVinci DA850 SATA AHCI support fully functional are in the separate "ARM: davinci: da850: update SATA AHCI support" commit. Please note that this driver doesn't have the superfluous clock control code as clock is already handled by the generic AHCI platform library code.

Looking at ST SPEAr1340 AHCI code (the only user of the deprecated pdata->suspend and pdata->resume) it is obvious the we should return after calling pdata->suspend() only if the function have returned non-zero return value. The code has been broken since commit 1e70c2 ("ata/ahci_platform: Add clock framework support"). Fix it.

2014-03-25spi: topcliff-pch: Transform noisy message to dev_vdbgAlexander Stein
If during a SPI transfer with len larger than PCH_MAX_FIFO_DEPTH and the IRQ handler happens to be called when the transmit FIFO is already empty, and SPSR_FI_BIT is set consequently, the message "spi_master spi32766: pch_spi_handler_sub : Transfer is not completed" is spammed to the systemlog, because tx_index has already increased further due to the next bytes to be written.

2014-03-25xen/balloon: flush persistent kmaps in correct positionWei Liu
Xen balloon driver will update ballooned out pages' P2M entries to point to scratch page for PV guests. In 24f69373e2 ("xen/balloon: don't alloc page while non-preemptible", kmap_flush_unused was moved after updating P2M table. In that case for 32 bit PV guest we might end up with P2M X -----> S (S is mfn of balloon scratch page) M2P Y -----> X (Y is mfn in persistent kmap entry) kmap_flush_unused() iterates through all the PTEs in the kmap address space, using pte_to_page() to obtain the page. If the p2m and the m2p are inconsistent the incorrect page is returned. This will clear page->address on the wrong page which may cause subsequent oopses if that page is currently kmap'ed. Move the flush back between get_page and __set_phys_to_machine to fix this.
