        In 5.6 it was set to non-prompt for x86 and forced to 0, but this

        reverted. Distros would need to restore CONFIG_SND_HDA_PREALLOC_SIZE

        Other than that, we've received quite a few small fixes for HD-audio

      btrfs: fix setting last_trans for reloc roots · aec7db3b
      Josef Bacik authored
      I made a mistake with my previous fix, I assumed that we didn't need to
      mess with the reloc roots once we were out of the part of relocation where
      we are actually moving the extents.
      
      The subtle thing that I missed is that btrfs_init_reloc_root() also
      updates the last_trans for the reloc root when we do
      btrfs_record_root_in_trans() for the corresponding fs_root.  I've added a
      comment to make sure future me doesn't make this mistake again.
      
      This showed up as a WARN_ON() in btrfs_copy_root() because our
      last_trans didn't == the current transid.  This could happen if we
      snapshotted a fs root with a reloc root after we set
      rc->create_reloc_tree = 0, but before we actually merge the reloc root.
      
      Worth mentioning that the regression produced the following warning
      when running snapshot creation and balance in parallel:

      amd-xgbe: Use __napi_schedule() in BH context · d518691c
      Sebastian Andrzej Siewior authored
      The driver uses __napi_schedule_irqoff() which is fine as long as it is
      invoked with disabled interrupts by everybody. Since the commit
      mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq
      context. This may lead to list corruption if another driver uses
      __napi_schedule_irqoff() in IRQ context.
      
      Use __napi_schedule() which safe to use from IRQ and softirq context.

      net: stmmac: dwmac-sunxi: Provide TX and RX fifo sizes · 806fd188
      Florian Fainelli authored
      After commit bfcb8132 ("net: dsa:
      configure the MTU for switch ports") my Lamobo R1 platform which uses
      an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail
      by rejecting a MTU of 1536. The reason for that is that the DMA
      capabilities are not readable on this version of the IP, and there
      is also no 'tx-fifo-depth' property being provided in Device Tree. The
      property is documented as optional, and is not provided.
      
      Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so
      provide these values through platform data as an immediate fix until
      various Device Tree sources get updated accordingly.

      and a read after lseek beyond end of file results in the last line being
      shown:
