      [ARM] Update atomic.h · 135247bf
      Russell King authored
      This re-jigs atomic.h by providing atomic_add_return and
      atomic_sub_return as other architectures do.  This allows us to
      implement the atomic ops that test the new value without having
      to write the underlying atomic operation in various forms.

      [ARM] Fix use of page->count · 1f20fe30
      Ian Campbell authored
      Patch from: Ian Campbell
      
      This changes the atomic_t in struct page named count into a private
      member _count which breaks arch/arm/mm/init.c at line 80 which reads
      page->count directly in show_mem().
                                                                                      
      The comments in the above changeset suggest that page_count(page) is
      precisely equal to the old page->count semantics, even though the
      semantics of _count are different, so I think the following is correct

      [PATCH] USB: ethernet/rndis gadget address params · 331a2d82
      David Brownell authored
      This resolves a FIXME by adding module parameters that can
      be used to provide stable (vs random) addresses, and gets
      rid of a runtime error from obsolete module parameter usage
      in the RNDIS code.
      
      The stable ethernet addresses are nice to hosts, which will
      normally want to save them away in config databases.  For
      example, without stable addresses Windows XP will end up
      recording quite a lot of RNDIS devices.

      [PATCH] USB: RNDIS (and CDC) filter flag handling · eaab83eb
      David Brownell authored
      This should fix the problem David Meggy found, where RNDIS was setting
      the OID_GEN_CURRENT_PACKET_FILTER state incorrectly.  It's the same
      issue Andrew Morton noticed a while back, for that matter, but with
      more than just a "now compiles on 64 bit" fix.
      
      Basically the code needs to interpret 32 bits provided in the request
      from the (Windows) host, rather than 8 bits of other memory that's got
      some irrelevant value.
      
      The fix is just to save the 32 bits.  I did the same thing with the
      CDC Ethernet filter, which should eventually be used the same way:  to
      limit what packets get sent to the host.  Also defined a couple more
      of the CDC requests.

      [libata] replace ATA_QCFLAG_ATAPI with inline helper · 043ea303
      Jeff Garzik authored
      Detection of an ATAPI taskfile is possible using a simple test
      on existing information, so there is no need to cache this value
      in a separate flag (ATA_QCFLAG_ATAPI).  Instead, create and use
      a new helper function is_atapi_taskfile().

      	* correct page length
      	* set bit, if read-ahead is disabled
      	* set bit, if writeback caching is enabled
      	  (previously, this bit was never set, even if
      	   writeback caching was enabled)

      [libata] SCSI->ATA simulator hacking: INQUIRY command · 7f594e47
      Jeff Garzik authored
      The SCSI T10 committee is working on a document describing a standard
      method for translating ATA<->SCSI, since it being done quite often
      these days.  Some of the recommendations are reasonable, and we implement
      two here:
      
      * Mirror that ATA 'removeable media' bit into INQUIRY output.
      * Change behavior of INQUIRY output field 'product revision' from
        the libata software version number to the first 4 bytes of the
        ATA device's firmware revision number.
      
      Rather than cache the firmware revision in struct ata_device, as was/is
      done with two other strings, I took the opportunity to eliminate the
      caching of the two other strings, 'vendor' and 'product'.  These strings
      are now retrieved as needed from the IDENTIFY [PACKET] DEVICE info page,
      since we cache its entire contents.
      
      Retrieving a string from the identify-device page is done via the
      helper function ata_dev_id_string(), which is now exported.
      
      This patch winds up making struct ata_device 40 bytes smaller, and
      the libata core gets a bit smaller as well.

      [libata] remove redundant use of ATA_QCFLAG_SG in ATAPI packet translation · e9c8846e
      Jeff Garzik authored
      ata_scsi_translate() sets this flag for all ATA->SCSI translated
      commands, so it need not be done in atapi_xlat().  The now-removed
      use in atapi_xlat() was also inconsistent WRT PIO versus DMA.

      [libata] DMADIR support · d89ee021
      Jeff Garzik authored
      DMADIR bit is necessary for some PATA->SATA bridges.  These
      bridges require the OS driver to specify the data xfer direction,
      for PACKET (a.k.a. scsi) commands.
      
      A reliable DMADIR detection method hasn't yet been developed,
      and ATAPI is still a WIP, so DMADIR is enabled with an ifdef for
      now.

      [SERIAL] Remove base_baud default from 8250_pci · abec7137
      Russell King authored
      Since all boards specify base_baud, the code to default base_baud to
      the architecture-defined BASE_BAUD is redundant.  Also, defaulting
      to the architecture-defined BASE_BAUD is wrong since the UARTs on a
      serial PCI card will be clocked at the same rate no matter what the
      architecture of the host machine.
