      [PATCH] libata: Incorrect timing computation for PIO5/6 · fd3367af
      Alan authored 
      The ata timing computation code makes some mistakes in PIO5/6 because a
check was not updated correctly when I put this support into the kernel.

      [PATCH] sata_promise: new EH conversion, take 2 · 25b93d81
      Mikael Pettersson authored 
      This patch converts sata_promise to use new-style libata error
handling on Promise SATA chips, for both SATA and PATA ports.

* ATA_FLAG_SRST is no longer set
* ->phy_reset is no longer set as it is unused when ->error_handler
   is present, and pdc_sata_phy_reset() has been removed
* pdc_freeze() masks interrupts and halts DMA via PDC_CTLSTAT
* pdc_thaw() clears interrupt status in PDC_INT_SEQMASK and then
  unmasks interrupts in PDC_CTLSTAT
* pdc_error_handler() reinitialises the port if it isn't frozen,
  and then invokes ata_do_eh() with standard {s,}ata reset methods
* pdc_post_internal_cmd() resets the port in case of errors
* the PATA-only 20619 chip continues to use old-style EH:
  not by necessity but simply because I don't have documentation
  for it or any way to test it

Since the previous version pdc_error_handler() has been rewritten
and it now mostly matches ahci and sata_sil24. In case anyone
wonders: the call to pdc_reset_port() isn't a heavy-duty reset,
it's a light-weight reset to quickly put a port into a sane state.

The discussion about the PCI flushes in pdc_freeze() and pdc_thaw()
seemed to end with a consensus that the flushes are OK and not
obviously redundant, so I decided to keep them for now.

This patch was prepared against 2.6.19-git7, but it also applies
to 2.6.19 + libata #upstream, with or without the revised sata_promise
cleanup patch I recently submitted.

This patch does conflict with the #promise-sata-pata patch:
this patch removes pdc_sata_phy_reset() while #promise-sata-pata
modifies it. The correct patch resolution is to remove the function.

Tested on 2037x and 2057x chips, with PATA patches on top and disks
on both SATA and PATA ports.

      [PATCH] libata: let ATA_FLAG_PIO_POLLING use polling pio for ATA_PROT_NODATA · e3472cbe
      Albert Lee authored 
      Even if ATA_FLAG_PIO_POLLING is set, libata uses irq pio for the ATA_PROT_NODATA protocol.
This patch let ATA_FLAG_PIO_POLLING use polling pio for the ATA_PROT_NODATA protocol.

      [PATCH] sata_promise: cleanups, take 2 · d324d462
      Mikael Pettersson authored 
      This patch performs two simple cleanups of sata_promise.

* Remove board_20771 and map device id 0x3577 to board_2057x.
  After the recent corrections for SATAII chips, board_20771 and
  board_2057x were equivalent in the driver.

* Remove hp->hotplug_offset and use hp->flags & PDC_FLAG_GEN_II
  to compute hotplug_offset in pdc_host_init(). hp->hotplug_offset
  was used to distinguish 1st and 2nd generation chips in one
  particular case, but now we have that information in a more
  general form in hp->flags, so hp->hotplug_offset is redundant.

Changes since previous submission: rebased on libata-dev #upstream,
cleaned up hotplug_offset computation based on Tejun's comments,
expanded hotplug_offset removal rationale.

This patch does not depend on the pending new EH conversion patch.

      [PATCH] Clean up 'make help' output for documentation targets. · 6fc52f81
      Jesper Juhl authored 
      Here's a patch that cleans up the "make help" output a bit for the
documentation targets.

Currently the documentation targets are listed completely different than
all the other targets :

  Documentation targets:
    Linux kernel internal documentation in different formats:
    xmldocs (XML DocBook), psdocs (Postscript), pdfdocs (PDF)
    htmldocs (HTML), mandocs (man pages, use installmandocs to install)

with this patch they are more in line with the rest of the output :

  Documentation targets:
   Linux kernel internal documentation in different formats:
    htmldocs        - HTML
    installmandocs  - install man pages generated by mandocs
    mandocs         - man pages
    pdfdocs         - PDF
    psdocs          - Postscript
    xmldocs         - XML DocBook
