      [PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 drive · b887030a
      由 Andrew Chew 提交于 
      This patch works around a problem with spurious interrupts seen at boot time when
a MAXTOR 6H500F0 drive is present.  An ATA interrupt condition is mysteriously
present at start of day.  If we took too long in issuing the first command,
the kernel would basically get tired of the spurious interrupts and turn the interrupt
off.  Issuing the first command essentially causes the interrupt condition to
get acknowledged.

I haven't seen this happen with any other drives.

What I basically do is ack ATA status by reading it regardless of whether we're
expecting to have to handle an interrupt.  This clears the start-of-day anomalous
interrupt condition, and keeps the kernel from disabling that interrupt due to
too many spurious interrupts.

Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled
in the ISR.  This was not the cause of the spurious interrupts, but it's the right
thing to do anyway.

      [SCSI] Kill the SCSI softirq handling · 1aea6434
      由 Jens Axboe 提交于 
      This patch moves the SCSI softirq handling to the block layer version.
There should be no functional changes.

      [ARM] Remove asm/irq.h includes from ARM drivers · e9368f82
      由 Russell King 提交于 
      Many ARM drivers do not need to include asm/irq.h - remove this
unnecessary include from some ARM drivers.

      [PATCH] Add block_device_operations.getgeo block device method · a885c8c4
      由 Christoph Hellwig 提交于 
      HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

      [PATCH] powerpc: Remove device_node addrs/n_addr · cc5d0189
      由 Benjamin Herrenschmidt 提交于 
      The pre-parsed addrs/n_addrs fields in struct device_node are finally
gone. Remove the dodgy heuristics that did that parsing at boot and
remove the fields themselves since we now have a good replacement with
the new OF parsing code. This patch also fixes a bunch of drivers to use
the new code instead, so that at least pmac32, pseries, iseries and g5
defconfigs build.
