      [PATCH] sd.c · 52f97cf3
      Andries E. Brouwer authored
      The below does two things:
      (i) do not try to spin up a CF reader without media
      (ii) be careful when asking for the cache parameters mode page
      
      [do not ask for this page when no media are present:
      it is meaningless, and some devices react badly if we do;
      check the reply so that we do not read past the end of the reply;
      first give a small transport length - some USB devices are unhappy
      if we ask for more than they provide]

      [PATCH] linux-2.5.57_delay-cleanup_A1.patch · 8c777fd8
      John Stultz authored
      This cleans up the delay code by moving the timer-specific
      implementations into the timer_ops struct.  Thus, rather then doing:
      
      	if(x86_delay_tsc)
      		__rdtsc_delay(loops);
      	else if(x86_delay_cyclone)
      		__cyclone_delay(loops);
      	else if(whatever....
      
      we just simply do:
      
      	timer->delay(loops);
      
      Making it much easier to accommodate alternate time sources.

      [PATCH] linux-2.5.57_timer-none_A0.patch · cab1826e
      John Stultz authored
      This creates an empty timer_opt structure (timer_none) which is then
      used as a default initializer to the timer pointer.  This lets us avoid
      having to check before dereferencing the timer in future code.

      [PATCH] use <asm/bug.h> for BUG() defines · 9e535055
      Russell King authored
      This patch moves BUG() and PAGE_BUG() from asm/page.h into asm/bug.h.
      
      We also fix up linux/dcache.h, which included asm/page.h for the sole
      purpose of getting the BUG() definition.
      
      Since linux/kernel.h and linux/smp.h make use of BUG(), asm/bug.h is
      included there as well.
      
      In addition, linux/jbd.h did not contain a clear path with which to
      obtain the archtecture BUG() definition, but did contain its own
      definition.

      [PATCH] Don't ask about "Enhanced Real Time Clock Support" on some archs · fb5805fb
      Tom Rini authored
      The following patch adds an explicit no list of arches who do not want
      to have the "Enhanced Real Time Clock Support" RTC driver asked.  This
      adds PPC32 (who for a long time had their own 'generic' RTC driver, and
      then have adopted the genrtc driver) and PARISC (who have always used
      the genrtc driver).  Per request of Peter Chubb, IA64 is on this list as
      well.
      
      The problem is that on some archs there is no hope of this driver
      working, and having it compiled into the kernel can cause many different
      problems.  On the other hand, there are some arches for whom that driver
      does work, on some platforms.  So having an explicit yes list would
      result in some rather ugly statements.

      [PATCH] cpufreq: per-CPU initialization · d97c3377
      Dominik Brodowski authored
      Allow for per-CPU initialization of CPUfreq. Therefore, it's not
      necessary any longer to kmalloc the per-CPU policy struct. To use
      this, cpufreq_driver->policy has to be set to NULL. Of course,
      cpufreq_driver->init is needed then, which is the appropriate function
      for CPU initialization. cpufreq_driver->exit is available for cleanup.
      
      All existing drivers continue to work without any changes, just for
      clarity ->init and ->exit are set to NULL, and the names accordingly.

      [PATCH] ohci/ehci debug updates for 2.5.56 · 023c5be4
      Kevin Brosius authored
        These two files needed to be touched after the recent changes to
      DRIVER_ATTR/driver_attribute structure members in 2.5.56.  Personally,
      it doesn't look to me like the size parameter should be removed, as now
      users will need to hardcode PAGE_SIZE into their functions, rather than
      it being passed from the place of allocation.  But I'm not familiar with
      the driverfs changes, so can't really say.
      
      These changes, or something similar, are needed to make ohci-dbg and
      ehci-dbg work at all in 2.5.56.  ehci is untested, but compiles here.
      I've tested the ohci changes and they appear to work.

      [PATCH] minimal Kerberos V5 client support [6/6] · e0594725
      Trond Myklebust authored
      The following patch provides minimal client support for the
      (mandatory) Kerberos V5 authentication mechanism under RPCSEC_GSS.
      See RFC2623 and RFC3010 for protocol details.
      
      Only authentication is supported for the moment. Data integrity and/or
      data privacy (encryption) will be implemented at a later stage.

      [PATCH] RPCSEC_GSS client upcall user [5/6] · a4419dbb
      Trond Myklebust authored
      This patches the RPCSEC_GSS client to make use of the upcall mechanism
      that was provided by patch [3/6].
      
      If an RPC task presents a non-uptodate credential to call_refresh(),
      a user daemon is contacted by means of a dedicated rpc_pipefs pipe.
      The daemon is then fed the uid for which it must establish a new RPCSEC
      security context.
      
      While the daemon goes about its business, the RPC task is put to sleep
      on a wait queue in order to allow the 'rpciod' process to service other
      requests. If another task wants to use the same credential, it too will
      be put to sleep once it reaches call_refresh(). A timeout mechanism
      ensures that requests are retried (or that 'soft' mounts fail) if the
      daemon crashes / is killed.
      
      Once the daemon has established the RPCSEC context, it writes the result
      back to the pipe, causing the credential to be updated. Those RPC tasks
      that were sleeping on the context are automatically woken up, and
      their execution can proceed.

      [PATCH] RPCSEC_GSS authentication framework [4/6] · 8d188768
      Trond Myklebust authored
      This patch provides the basic framework for RPCSEC_GSS authentication
      in the RPC client. The protocol is fully described in RFC-2203.
      Sun has supported it in their commercial NFSv3 and v2 implementations
      for quite some time, and it has been specified in RFC3010 as being
      mandatory for NFSv4.
      
        - Update the mount_data struct for NFSv2 and v3 in order to allow them
          to pass an RPCSEC_GSS security flavour. Compatibility with existing
          versions of the 'mount' program is ensured by requiring that RPCSEC
          support be enabled using the new flag NFS_MOUNT_SECFLAVOUR.
        - Provide secure authentication, and later data encryption on
          a per-user basis. A later patch will an provide an implementation
          of the Kerberos 5 security mechanism. SPKM and LIPKEY are still
          being planned.
        - Security context negotiation and initialization are all assumed
          to be done in userland. A later patch will provide the actual upcall
          mechanisms to allow for this.

      [PATCH] RPCSEC upcall mechanism [3/6] · af2f0033
      Trond Myklebust authored
      This patch provides the upcall mechanism that will be used for communicating
      with the RPCSEC client user daemons.
      
      It sets up a 'ramfs' style filesystem (rpc_pipefs) that is populated with
      named pipes. Each time the kernel initializes a new NFS, lockd, statd or
      portmapper client, a directory automatically gets set up in this fs.
      The directory is initially only populated with a single file "info"
      that provides information such as the server IP address, the port number
      and the RPC service for the benefit of the user daemon.
      
      When an RPCSEC_GSS mechanism needs to communicate with the daemon, it
      is provided with a toolkit for setting up a named pipe in the same
      directory. It can then perform upcalls/downcalls in order to talk to the
      daemon in much the same way as is done by CODA.
      
      The NFSv4 client will also need to use this same filesystem to communicate
      with its user daemon in order to do name-to-uid/name-from-uid and
      name-to-gid/name-from-gid translation.

      [PATCH] XDR 'encode' phase move [2/6] · 6d52fdcb
      Trond Myklebust authored
      The RPCSEC_GSS user context defines a 'sequence number' in the AUTH header
      fields in order to provide protection against replay attacks. This
      number needs to lie within a given 'window', and is required to be updated
      even when retransmitting dropped requests.
      
      In order to allow this update to occur, move the XDR 'encode' phase
      so that it is done immediately before writing the data to the socket.

      [PATCH] Clean up RPC client credcache lookups [1/6] · 756a93f7
      Trond Myklebust authored
      Clean up RPC client credcache lookups.
      
          - Remove the limitation whereby the RPC client may only look up
            credentials for the current task.
      
      The ability to lookup arbitrary credentials is needed in order to allow
      a user daemon to set the RPCSEC_GSS private information once it
      has finished negotiating the RPCSEC user context with the server.

      [PATCH] rbtree core for io scheduler · 68fc0a78
      Jens Axboe authored
      This patch has a bunch of io scheduler goodies that are, by now, well
      tested in -mm and by self and Nick Piggin. In order of interest:
      
      - Use rbtree data structure for sorting of requests. Even with the
        default queue lengths that are fairly short, this cuts a lot of run
        time for io scheduler intensive work loads. If we go to longer queue
        lengths, it very quickly becomes a necessity.
      
      - Add sysfs interface for the tunables. At the same time, finally kill
        the BLKELVGET/BLKELVSET completely. I made these return -ENOTTY in
        2.5.1, but there are left-overs around the kernel. This old interface
        was never any good, it was centered around just one io scheduler.
      
      The io scheduler core itself has received count less hours of tuning by
      myself and Nick, should be in pretty good shape. Please apply.
      
      Andrew, I made some sysfs changes to the version from 2.5.56-mm1. It
      didn't even compile without warnings (or work, for that matter), as the
      sysfs store/show procedures needed updating. Hmm?

      [PATCH] cpufreq: add sysfs interface · 74e7a24b
      Dominik Brodowski authored
      This patch adds a sysfs interface to the cpufreq core, and marks the
      previous /proc/cpufreq interface as deprecated.
      
      As in drivers/base/cpu.c a "CPU driver" is registered, cpufreq acts as
      "interface" to this, offering the following files for each CPU
      (in /system/devices/sys/cpu.../) where CPUfreq support is present
      
      cpuinfo_min_freq (ro)	- minimum frequency (in kHz) the CPU supports
      cpuinfo_max_freq (ro)	- maximum frequency (in kHz) the CPU supports
      scaling_min_freq (rw)	- minimum frequency (in kHz) cpufreq may scale
      			     the CPU core to
      scaling_max_freq (rw)	- maximum frequency (in kHz) cpufreq may scale
      			     the CPU core to
      scaling_governor (rw)	- governor == "A feedback device on a machine
      			      or engine that is used to provide
      			      automatic control, as of speed,
      			      pressure, or temperature" [1, as noted
      			      by David Kimdon]. Decides what frequency
      			      is used. Currently, only "performance"
      			      and "powersave" are supported, more may
      			      be added later.
      
      (In future, a file scaling_driver (ro) which shows what CPUfreq driver
      is used (arm-sa1100,  gx-suspmod, speedstep, longrun, powernow-k6,
      ...) might be added, and this driver will be allowed to add files
      scaling_driver_* for driver-specific settings like "prefer fast FSB".
      And scaling_governor_* files might offer settings for the governor.)
      
      To implement this sysfs interface, the driver model "interface" code
      is used. Unfortunately, it has a non-trivial locking bug in
      drivers/base/intf.c: there's a down_write call for
      cls->subsys.rwsem in add_intf(), which then calls add(), which may call
      intf->add_device(), which may call interface_add_data(), which calls
      kobject_register(), which calls kobject_add(), which then tries to
      down_write cls->subsys.rwsem. Remember, that was already locked writable
      in add_intf().
      
      Because of that, interface_add_data() is commented out; this means
      that no link in /system/class/cpu/cpufreq is added, and that the
      dev-removal code isn't called. This shouldn't be a problem yet,
      though; as no cpufreq driver I know of is capable of CPU hotplugging.
