      mtd: nand: vf610_nfc: Freescale NFC for VF610, MPC5125 and others · 456930d8
      Stefan Agner authored
      This driver supports Freescale NFC (NAND flash controller) found on
      Vybrid (VF610), MPC5125, MCF54418 and Kinetis K70. The driver has
      been tested using 8-bit and 16-bit NAND interface on the ARM based
      Vybrid SoC VF500 and VF610 platform.
      parameter page reading.
      
      Limitations:
      - Untested on MPC5125 and M54418.
      - DMA and pipelining not used.
      - 2K pages or less.
      - No chip select, one NAND chip per controller.
      - No hardware ECC.
      
      Some paths have been hand-optimized and evaluated by measurements
      made using mtd_speedtest.ko on a 100MB MTD partition.

      mtd: provide proper 32/64-bit compat_ioctl() support for BLKPG · 53bb724f
      Brian Norris authored
      After a bit of poking around wondering why my 32-bit user-space can't
      seem to send a proper ioctl(BLKPG) to an MTD on my 64-bit kernel
      (ARM64), I noticed that struct blkpg_ioctl_arg is actually pretty
      unsuitable for use in the ioctl() ABI, due to its use of raw pointers,
      and its lack of alignment/packing restrictions (32-bit arch'es tend to
      pack the 4 fields into 4 32-bit words, whereas 64-bit arch'es would add
      padding after the third int, and make this 6 32-bit words).
      
      Anyway, this means BLKPG deserves some special compat_ioctl handling. Do
      the conversion in a small shim for MTD.
      
      block/compat_ioctl.c already has compat support for the block subsystem,
      but it does so by a re-marshalling data to/from user-space (see
      compat_blkpg_ioctl()). Personally, I think this approach is cleaner.
      
      Tested only on MTD, with an ARM32 user space on an ARM64 kernel.

      mtd: spi-nor: scale up timeout for full-chip erase · 09b6a377
      Furquan Shaikh authored
      This patch fixes timeout issues seen on large NOR flash (e.g., 16MB
      w25q128fw) when using ioctl(MEMERASE) with offset=0 and length=16M. The
      input parameters matter because spi_nor_erase() uses a different code
      path for full-chip erase, where we use the SPINOR_OP_CHIP_ERASE (0xc7)
      opcode.
      
      Fix: use a different timeout for full-chip erase than for other
      commands.
      
      While most operations can be expected to perform relatively similarly
      across a variety of NOR flash types and sizes (and therefore might as
      well use a similar timeout to keep things simple), full-chip erase is
      unique, because the time it typically takes to complete:
      (1) is much larger than most operations and
      (2) scales with the size of the flash.
      
      Let's base our timeout on the original comments stuck here -- that a 2MB
      flash requires max 40s to erase.
      
      Small survey of a few flash datasheets I have lying around:
      
        Chip         Size (MB)   Max chip erase (seconds)
        ----         --------    ------------------------
        w25q32fw     4           50
        w25q64cv     8           30
        w25q64fw     8           100
        w25q128fw    16          200
        s25fl128s    16          ~256
        s25fl256s    32          ~512
      
      From this data, it seems plenty sufficient to say we need to wait for
      40 seconds for each 2MB of flash.
      
      After this change, it might make some sense to decrease the timeout for
      everything else, as even the most extreme operations (single block
      erase?) shouldn't take more than a handful of seconds. But for safety,
      let's leave it as-is. It's only an error case, after all, so we don't
      exactly need to optimize it.

      mtd: cmdlinepart: allow small partitions · d855d23b
      Brian Norris authored
      I'm not sure why we have a PAGE_SIZE restriction on this partition
      parser.
      
      If we really wanted the restriction, I would expect it to be a
      restriction for *all* parsers, so we'd move it to the MTD core
      
      At any rate, while small partitions may not be useful (they'll often be
      smaller than the eraseblock size and therefore can only be used
      read-only), they still have use as a read-only partition.
      
      This restriction is especially annoying because it aborts the entire
      MTD's cmdline parsing, leaving it unpartitioned.
      
      So, let's kill the restriction and only check for zero-sized partitions,
      which I expect we don't want to allow.

      mtd: nand: pxa3xx-nand: prevent DFI bus lockup on removal · e971affa
      Robert Jarzmik authored
      After the conversion of pxa architecture to common clock framework, the
      NAND clock can be disabled on driver exit.
      
      In this case, it happens that if the driver used the NAND and set the
      DFI arbitration bit, the next access to a static memory controller area,
      such as an ethernet card, will stall the system bus, and the core will
      be stalled forever.
      
      This is especially true on pxa31x SoCs, where the NDCR was augmented
      with a new bit to prevent this lockups by giving full ownership of the
      DFI arbiter to the SMC, in change SCr#6.
      
      Fix this by clearing the DFI arbritration bit in driver exit. This
      effectively prevents a lockup on zylonite when removing pxa3xx-nand
      module, and using ethernet afterwards.

      blk: rq_data_dir() should not return a boolean · 10fbd36e
      Linus Torvalds authored
      rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
      a boolean value.
      
      Now, admittedly the "!= 0" doesn't really change the value (0 stays as
      zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
      causes gcc to warn about the construct
      
          switch (rq_data_dir(req)) {
              case READ:
                  ...
              case WRITE:
                  ...
      
      that we have in a few drivers.
      
      Now, the gcc warning is silly and stupid (it seems to warn not about the
      switch value having a different type from the case statements, but about
      _any_ boolean switch value), but in this case the code itself is silly
      and stupid too, so let's just change it, and get rid of warnings like
      this:
      
        drivers/block/hd.c: In function ‘hd_request’:
        drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
           switch (rq_data_dir(req)) {
      
      The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
      commit 5953316d ("block: make rq->cmd_flags be 64-bit") and is
      presumably because the old code (that just did a logical 'and' with 1)
      would then end up making the type of rq_data_dir() be u64 too.
      
      But if we want to retain the old regular integer type, let's just cast
      the result to 'int' rather than use that rather odd '!= 0'.

      We had to revert the pluggin in writeback_sb_inodes() because the
      wb->list_lock is held, but we could easily plug at a higher level before
      taking that lock, and unplug after releasing it.  This does that.
      
      Chris will run performance numbers, just to verify that this approach is
      comparable to the alternative (we could just drop and re-take the lock
      around the blk_finish_plug() rather than these two commits.
      
      I'd have preferred waiting for actual performance numbers before picking
      one approach over the other, but I don't want to release rc1 with the
      known "sleeping function called from invalid context" issue, so I'll
      pick this cleanup version for now.  But if the numbers show that we
      really want to plug just at the writeback_sb_inodes() level, and we

      thermal: fix intel PCH thermal driver mismerge · dfb22fc5
      Linus Torvalds authored
      I didn't notice this when merging the thermal code from Zhang, but his
      merge (commit 5a924a07: "Merge branches 'thermal-core' and
      'thermal-intel' of .git into next") of the thermal-core and
      thermal-intel branches was wrong.
      
      In thermal-core, commit 17e8351a ("thermal: consistently use int for
      temperatures") converted the thermal layer to use "int" for
      temperatures.
      
      But in parallel, in the thermal-intel branch commit d0a12625
      ("thermal: Add Intel PCH thermal driver") added support for the intel
      PCH thermal sensor using the old interfaces that used "unsigned long"
      pointers.
      
      This resulted in warnings like this:
      
        drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
          .get_temp = pch_thermal_get_temp,
                      ^
        drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’)
        drivers/thermal/intel_pch_thermal.c:186:19: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
          .get_trip_temp = pch_get_trip_temp,
                           ^
        drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization for ‘tzd_ops.get_trip_temp’)
      
      This fixes it.
