      [PATCH] ppc32: Handle altivec assist exception properly · 66a7d6a6
      Andrew Morton authored
      From: Paul Mackerras <paulus@samba.org>
      
      On machines with Altivec (i.e.  G4 and G5 processors), the altivec
      floating-point instructions can operate in two modes: one where
      denormalized inputs or outputs are truncated to zero, and one where they
      aren't.  In the latter mode the processor can take an exception when it
      encounters denormalized floating-point inputs or outputs rather than
      dealing with them in hardware.
      
      This patch adds code to deal properly with the exception, by emulating the
      instruction that caused the exception.  Previously the kernel just switched
      the altivec unit into the truncate-to-zero mode, which works but is a bit
      gross.  Fortunately there are only a limited set of altivec instructions
      which can generate the assist exception, so we don't have to emulate the
      whole altivec instruction set.
      
      This patch also makes sure that we always have a handler for the altivec
      unavailable exception.  Without this, if you run a kernel that is not
      configured for altivec support on a machine with altivec, it works fine
      until a user process tries to execute an altivec instruction.  At that
      point the kernel thinks it has taken an unknown exception and panics.  With
      this patch it sends a SIGILL to the process instead.

      [PATCH] ppc32: some whitespace fixes · 26b271be
      Andrew Morton authored
      From: Paul Mackerras <paulus@samba.org>
      
      This patch does nothing but fix up whitespace in three files in arch/ppc.
      It deletes trailing blanks and tabs in several places and joins two lines
      that didn't need to be split.

      [PATCH] ppc32: IBM PowerPC 750GX Support · ea8b94ab
      Andrew Morton authored
      From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
      
      From: Bryan Rittmeyer <bryan@staidm.org>
      
      This patch adds preliminary support for the IBM PowerPC 750GX.  In summary
      this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2 and more
      advanced I/O pipelining.  It is beginning to appear in embedded systems and
      was rumored to be under evaluation inside Apple.  Tested on PVR 70020101;
      please merge.

      [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

      [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.

      DMADIR bit is necessary for some PATA->SATA bridges.  These

      and ATAPI is still a WIP, so DMADIR is enabled with an ifdef for
      now.
