The function ipw_request_direct_scan() should bail out when the device
is down.  This fixes a lockup caused by wpa_supplicant triggering
ipw_request_direct_scan() while the driver was in a middle of a reset
due to firmware errors.

Thanks to Zilvinas Valinskas for reporting the bug and helping me
debug it.

Despite the fact that md threads don't need to be signalled, and won't
respond to signals anyway, we need to have an 'interruptible' wait, else
they stay in 'D' state and add to the load average.

(akpm: the signal_pending() test is unneeded - we'll fix that up in the next
round.  For now, leave it there because that's how the code used to be).

- Move ATAPI check-condition handling out of the timeout handler
- Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET
  command upon receiving an ATAPI check-condition.

This cleans things up a lot, and eliminates a nasty recursion bug.

- in ata_dev_identify(), don't assume that all devices are either
  ATA or ATAPI.  In the future, this code will see port multipliers
  and other devices.
- make a debugging printk less verbose
- add new helper ata_qc_reinit()
- add new helper BPRINTK() and port flag ATA_FLAG_DEBUGMSG, for
  fine-grained debugging use.

The ATAPI pad-to-next-32bit-boundary code modifies the scatterlist's
length variable, sometimes to zero.  x86-64 platform would oops if a
zero-length scatterlist entry was asked to be mapped.  Work around this
by ensuring that we never DMA-map a zero length buffer or SG entry.

Needed to get ATAPI working.

- dump hardware error bits, if hardware signals an error
- only reset hardware during timeout if a command was active
- call ata_qc_complete() with a fine-grained error mask.
  Needed so that atapi_qc_complete() can distinguish between
  device errors and other errors.

This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel,
and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate
of the genrtc functionality. Also enable build of genrtc for
CONFIG_PPC64 (it just works are we already have the required callbacks)
and enable it in all defconfigs.

The following patch caused some duplicated code in cx88-dvb.c:
[PATCH] v4l: 634: implemented tuner set standby on cx88 init

The cx88-dvb.c portion of this patch was already applied
in an earlier patch, entitled:
[PATCH] v4l: fixup on cx88_dvb for Dvico HDTV5 Gold

I love quilt and all, but AFAIK, no tool is 100% perfect for catching
oversights like this.

The non-overlapping portions of each of these patches are still needed, and
must not be discarded, so rather than reverting old patches, please just apply
this fixup patch to remove the duplicated code.
