      ASoC: Intel: Fix audio crash due to negative address offset · 95e9ee92
      Wenkai Du authored
      There were occasional ADSP crash during reboot testing:
      
      [   11.883364] BUG: unable to handle kernel paging request at ffffc90121700000
      [   11.883380] IP: [<ffffffffc024d8bc>] sst_module_insert_fixed_block+0x24f/0x26d [snd_soc_sst_dsp]
      [   11.883397] PGD 7800b067 PUD 0
      [   11.883405] Oops: 0002 [#1] SMP
      [   11.886418] gsmi: Log Shutdown Reason 0x03
      
      The virtual address, ffffc90121700000, was out of range. The virtual
      address is calculated by adding LPE base address with an offset:
      
      sst_memcpy32(dsp->addr.lpe + data->offset, data->data, data->size);
      
      The offset is calculated in sst_byt_parse_module, by subtraction of
      two virtual addresses dsp->addr.fw_ext and dsp->addr.lpe:
      
      block_data.offset = block->ram_offset + (dsp->addr.fw_ext - dsp->addr.lpe);
      
      These virtual addresses are assigned by kernel from ioremap:
      
      sst->addr.lpe = ioremap(pdata->lpe_base, pdata->lpe_size);
      sst->addr.fw_ext = ioremap(pdata->fw_base, pdata->fw_size);
      
      In current driver code, offset is defined as unsigned int32:
      
      struct sst_module_data {
      ...
      	u32 offset;		/* offset in FW file */
      };
      
      Most of the time kernel assigned virtual addresses with addr.fw_ext
      greater than addr.lpe. But sometimes it was the other way round.
      
      Fix the problem by declaring offset as signed int32_t.

      mm: Initialize error in shmem_file_aio_read() · f7c1d074
      Geert Uytterhoeven authored
      Some versions of gcc even warn about it:
      
        mm/shmem.c: In function ‘shmem_file_aio_read’:
        mm/shmem.c:1414: warning: ‘error’ may be used uninitialized in this function
      
      If the loop is aborted during the first iteration by one of the two
      first break statements, error will be uninitialized.
      
      Introduced by commit 6e58e79d ("introduce copy_page_to_iter, kill
      loop over iovec in generic_file_aio_read()").

      cifs: Use min_t() when comparing "size_t" and "unsigned long" · e686bd8d
      Geert Uytterhoeven authored
      On 32 bit, size_t is "unsigned int", not "unsigned long", causing the
      following warning when comparing with PAGE_SIZE, which is always "unsigned
      long":
      
        fs/cifs/file.c: In function ‘cifs_readdata_to_iov’:
        fs/cifs/file.c:2757: warning: comparison of distinct pointer types lacks a cast
      
      Introduced by commit 7f25bba8 ("cifs_iovec_read: keep iov_iter
      between the calls of cifs_readdata_to_iov()"), which changed the
      signedness of "remaining" and the code from min_t() to min().

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka authored
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.
