      mmc: atmel-mci: prepare clk before calling enable · b3894f26
      Boris BREZILLON authored
      Replace clk_enable/disable with clk_prepare_enable/disable_unprepare to
      avoid common clk framework warnings.

      mmc: sd: fix the maximum au_size for SD3.0 · 77776fd0
      Jaehoon Chung authored
      Since SD Physical Layer specification V3.0, AU_SIZE is supported up
      to 0xf.  So If SD-card is supported v3.0, then max_au should be 0xf.

      mmc: core: free mmc_card if cmd 3,9,7 fails in mmc_sd_init_card · 7fca9675
      Wei WANG authored
      In function mmc_sd_init_card, if command 3/9/7 got failed, mmc_card
      allocated just before won't be freed. This would cause memory leak.

      mmc: omap_hsmmc: fix dependency on indirect header inclusion · 031cd037
      Felipe Balbi authored
      omap_hsmmc.c depends on <linux/sizes.h> being included indirectly by
      another header. Once we enable COMPILE_TEST for this driver, we might
      compile under architectures which won't include <linux/sizes.h> for us.
      In fact, one such case is x86.
      
      In order to prevent compile breakages, let's explicitly include
      <linux/sizes.h>.

      mmc: dw_mmc: Handle DW_MCI_QUIRK_IDMAC_DTO properly · 476d79f1
      Doug Anderson authored
      In (1fb5f68a mmc: dw_mmc: Don't loop when handling an interrupt), the
      code for handling DW_MCI_QUIRK_IDMAC_DTO became dead code.  Move it to
      where it ought to live.
      
      Found by code inspection and compile-tested only--I don't know of any
      boards that need DW_MCI_QUIRK_IDMAC_DTO.

      mmc: block: fix a bug of error handling in MMC driver · c8760069
      KOBAYASHI Yoshitake authored
      Current MMC driver doesn't handle generic error (bit19 of device
      status) in write sequence. As a result, write data gets lost when
      generic error occurs. For example, a generic error when updating a
      filesystem management information causes a loss of write data and
      corrupts the filesystem. In the worst case, the system will never
      boot.
      
      This patch includes the following functionality:
        1. To enable error checking for the response of CMD12 and CMD13
           in write command sequence
        2. To retry write sequence when a generic error occurs
      
      Messages are added for v2 to show what occurs.

      mmc: sdhci: request irq after sdhci_init() is called · 2af502ca
      Shawn Guo authored
      Generally request_irq() should be called after hardware has been
      initialized into a sane state.  However, sdhci driver currently calls
      request_irq() before sdhci_init().  At least, the following kernel panic
      seen on i.MX6 is caused by that.  The sdhci controller on i.MX6 may have
      noisy glitch on DAT1 line, which will trigger SDIO interrupt handling
      once request_irq() is called.  But at this point, the SDIO interrupt
      handler host->sdio_irq_thread has not been registered yet.  Thus, we
      see the NULL pointer access with wake_up_process(host->sdio_irq_thread)
      in mmc_signal_sdio_irq().
      
      Fix the panic by simply reverse the calling sequence between
      request_irq() and sdhci_init().

      mmc: mxs-mmc: Use devm_clk_get() · a5adbffd
      Fabio Estevam authored
      Using devm_clk_get() allows us to remove the clk_put() calls, so
      let's use it to simplify the code.
      
      Rename the 'out_clk_put' label to 'out_clk_disable' now that clk_put
      is removed.

      mmc: jz4740: fix return value check in jz4740_mmc_probe() · 3e7e8c18
      Wei Yongjun authored
      In case of error, the function devm_ioremap_resource() returns ERR_PTR()
      and never returns NULL. The NULL test in the return value check should
      be replaced with IS_ERR(). Also there is already a error message within
      devm_ioremap_resource(), so remove the dev_err call to avoid redundant
      error message.

       "This is a re-do of the net-next pull request for the current merge
        window.  The only difference from the one I made the other day is that
        this has Eliezer's interface renames and the timeout handling changes
        made based upon your feedback, as well as a few bug fixes that have
        trickeled in.
      
        Highlights:
      
         1) Low latency device polling, eliminating the cost of interrupt
            handling and context switches.  Allows direct polling of a network
            device from socket operations, such as recvmsg() and poll().
      
            Currently ixgbe, mlx4, and bnx2x support this feature.
      
            Full high level description, performance numbers, and design in
            commit 0a4db187 ("Merge branch 'll_poll'")
      
            From Eliezer Tamir.
      
         2) With the routing cache removed, ip_check_mc_rcu() gets exercised
            more than ever before in the case where we have lots of multicast
            addresses.  Use a hash table instead of a simple linked list, from
            Eric Dumazet.
      
         3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from

      Pull drm updates from Dave Airlie:
       "Okay this is the big one, I was stalled on the fbdev pull req as I
        stupidly let fbdev guys merge a patch I required to fix a warning with
        some patches I had, they ended up merging the patch from the wrong
        place, but the warning should be fixed.  In future I'll just take the
        patch myself!
      
        Outside drm:
      
        There are some snd changes for the HDMI audio interactions on haswell,
        they've been acked for inclusion via my tree.  This relies on the
        wound/wait tree from Ingo which is already merged.
      
        Major changes:
      
        AMD finally released the dynamic power management code for all their
        GPUs from r600->present day, this is great, off by default for now but
        also a huge amount of code, in fact it is most of this pull request.
      
        Since it landed there has been a lot of community testing and Alex has
        sent a lot of fixes for any bugs found so far.  I suspect radeon might
        now be the biggest kernel driver ever :-P p.s.  radeon.dpm=1 to enable
        dynamic powermanagement for anyone.
      
        New drivers:
      
        Renesas r-car display unit.
      
        Other highlights:
      
         - core: GEM CMA prime support, use new w/w mutexs for TTM
           reservations, cursor hotspot, doc updates
         - dvo chips: chrontel 7010B support
         - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
           Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
           support (this time for sure)
         - nouveau: async buffer object deletion, context/register init
           updates, kernel vp2 engine support, GF117 support, GK110 accel
           support (with external nvidia ucode), context cleanups.
         - exynos: memory leak fixes, Add S3C64XX SoC series support, device
           tree updates, common clock framework support,
         - qxl: cursor hotspot support, multi-monitor support, suspend/resume
           support
         - mgag200: hw cursor support, g200 mode limiting
         - shmobile: prime support
         - tegra: fixes mostly
      
        I've been banging on this quite a lot due to the size of it, and it
        seems to okay on everything I've tested it on."

      Reason for this crash is a gcc miscompilation in the fault handlers of
      pa_memcpy() which return the fault address instead of the copied bytes.
      Since this seems to be a generic problem with gcc-4.7.x (and below), it's
      better to simplify the fault handlers in pa_memcpy to avoid this problem.
      
      Here is a simple reproducer for the problem:
      
      int main(int argc, char **argv)
      {
      	int fd, nbytes;
      	struct iovec wr_iovec[] = {
      		{ "TEST STRING                     ",32},
      		{ (char*)0x40005000,32} }; // random memory.
      	fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666);
      	nbytes = writev(fd, wr_iovec, 2);
      	printf("return value = %d, errno %d (%s)\n",
      		nbytes, errno, strerror(errno));
      	return 0;
      }
      
      In addition, John David Anglin wrote:
      There is no gcc PR as pa_memcpy is not legitimate C code. There is an
      implicit assumption that certain variables will contain correct values
      when an exception occurs and the code randomly jumps to one of the
      exception blocks.  There is no guarantee of this.  If a PR was filed, it
      would likely be marked as invalid.

      parisc: Ensure volatile space register %sr1 is not clobbered · e8d8fc21
      John David Anglin authored
      I still see the occasional random segv on rp3440.  Looking at one of
      these (a code 15), it appeared the problem must be with the cache
      handling of anonymous pages.  Reviewing this, I noticed that the space
      register %sr1 might be being clobbered when we flush an anonymous page.
      
      Register %sr1 is used for TLB purges in a couple of places.  These
      purges are needed on PA8800 and PA8900 processors to ensure cache
      consistency of flushed cache lines.
      
      The solution here is simply to move the %sr1 load into the TLB lock
      region needed to ensure that one purge executes at a time on SMP
      systems.  This was already the case for one use.  After a few days of
      operation, I haven't had a random segv on my rp3440.
