      [PATCH] fix madvise(MADV_DONTNEED) for nonlinear vmas · d614d315
      Andrew Morton authored
      From: Hugh Dickins <hugh@veritas.com>
      
      Jamie points out that madvise(MADV_DONTNEED) should unmap pages from a
      nonlinear area in such a way that the nonlinear offsets are preserved if the
      pages do turn out to be needed later after all, instead of reverting them to
      linearity: needs to pass down a zap_details block.
      
      (But this still leaves mincore unaware of nonlinear vmas: bigger job.)

      Andrew Morton authored
      From: Chris Mason <mason@suse.com>
      
      reiserfs-delayed-work started using queue_delayed_work, but did not make sure
      the timer was finished before it freed the work queue structs during unmount. 
      This leads to timer oopsen if you unmount at just the right time.

      [PATCH] fix for potential deadlock after posix-timers change · f3276a18
      Roland McGrath authored
      Ulrich has been working on the glibc code using posix-timers and
      stressing it more now than it has before.  He ran into an SMP deadlock
      on process exit in the case there are pending queued signals from a
      timer.
      
      The deadlock arises because in the path through exit_itimers, the
      tasklist_lock is already held (for writing).  When a timer is being
      deleted, sigqueue_free will try to take it (for reading) in the case
      where that timer has a pending signal queued on somebody's queue.  This
      patch avoids the problem by making sure the queues are flushed before
      calling exit_itimers, thus ensuring its code path won't try to take
      tasklist_lock.

      [PATCH] ppc64: siginfo conversion fix · b4389817
      Benjamin Herrenschmidt authored
      My message queue patch fixes the 64 bits -> 32 bits conversion of
      siginfo, but didn't change the 32 -> 64 bits conversion done in
      sys32_rt_sigqueueinfo() which was apparently bogus as well.
      
      After much discussion & debate on the right way of converting that
      structure, I decided to go the sparc64 / s390 way, and not the x86_64
      way, that is to copy the various unions data "as is". This guarantees
      that whatever a 32 bist app passes there, another 32 bits app will
      understand it. Crossover between 32 and 64 bits apps on such things
      as home-made userland siginfo isn't something we can help with anyway.
      
      The x86_64 choice of converting as if it was an RT signal, thus
      converting the sigval, cannot easily be applied to big endian archs
      since the sigval is a union of a ptr and an int, on BE, the int
      happens to be on the wrong half of the 64 bits ptr, thus  we can't
      do a simple conversion.

      [PATCH] Fix hw_random build on ia64 · 36377f61
      Bjorn Helgaas authored
      The following patch allows hw_random.c to build on ia64.  (The problem
      was just that the VIA stuff has i386 assembly in it.  The current code
      only probes for VIA on i386 anyway, so this patch just adds more ifdefs
      so the VIA code is only built for i386.)

      [PATCH] Tulip endianess fix · d86d6aaa
      Pavel Roskin authored
      My tulip ethernet card doesn't work on Blue&White G3 PowerMac with Linux
      2.6.5-rc2.  The card is shown by lspci as
      
      01:03.0 Ethernet controller: Linksys Network Everywhere Fast Ethernet
      10/100 model NC100 (rev 11)
      
      The kernel detects it as "ADMtek Comet rev 17".
      
      The MAC address reported by the kernel looked obviously wrong.  Also, I
      could only ping the system successfully if the interface was in promiscuous
      mode (running Ethereal).
      
      Those two symptoms indicated two different problems - one for reading the
      MAC address from the card on module load (tulip_init_one), and the other
      for writing the address to the card when the interface was brought up
      (tulip_up).  I have fixed both, and here's the explanation:
      
      tulip_init_one:
      
      When reading the first 4 bytes of the address, inl() returns the same data
      to the CPU on all platforms, interpreting the data from the lowest port
      address as the least significant byte.  In other words, I/O is little
      endian on all platforms; it's the memory that differs across platforms.
      We want to write the data to memory preserving little-endianness of the
      PCI bus.  To force little endian write to the memory, the data should be
      converted to the little endian format.
      
      When reading the remaining 2 bytes, the CPU gets them in 2 least
      significant bytes.  To write those 2 bytes to the memory in a 16-bit
      operation, they should be byte-swapped for the 16-bit operation.
      
      tulip_up:
      
      The first 4 bytes are processed correctly, but the code is confusing.
      Reading from memory needs conversion to CPU format, while writing to I/O
      ports doesn't.  So I replaced cpu_to_le32() to le32_to_cpu().
      
      The second 2 bytes are read in a 16-bit memory operation, so they should
      be passed to le16_to_cpu() rather than cpu_to_le32() to make them CPU
      independent and suitable for outl().
      
      
      All those conversions do nothing on little-endian machines, so they should
      not be affected.
      
      The patch has been tested.  The driver is working fine.  ping is OK, ssh
      is OK, X11 over ssh is OK.  Even netconsole is working fine.

      I didn't particularly like the PRIV() method implemented previously -
      gcc appears to want to avoid some optimisations it if its an inline
      function rather than a macro.
      
      Also, 'ei_local' may look unused in some functions, but it's your
      typical hidden-use-in-a-macro crap which 8390 likes.

      [PATCH] Mixed PCI/ISA device name conflicts · 66dbee35
      Stephen Hemminger authored
      In systems with mixed network cards, and all drivers compiled into
      the kernel; the PCI device (eth0) will get probed first, before the ISA.
      
      The problem is that the ISA device can mistakenly try to probe
      for eth0.  The problem is that the ISA driver will not detect the failure
      until it goes to call register_netdevice, and not all drivers have
      perfect error unwind code.
      
      This patch short circuits the device probe, so it won't bother
      looking for devices that already are registered.

      Looks like a bug.  Possible patch below zeros the buffer (since it's not

      Hrm, I believe you could use this to read 128k of kernel memory.
      sdla_read() takes len as a short, whereas mem.len is an int.  So,
      if mem.len == 0x20000, the allocation could still succeed.  When cast
      to short, len will be 0x0, causing the read loop to copy nothing into
      the buffer.  At least it's protected by a capable() check.  I don't
      know what proper upper bound is for this hardware, or how much it's
      used/cared about.  Simple memset() is trivial fix.
