      [PATCH] Pass the load address into ELF_PLAT_INIT() · 544db1a2
      Andrew Morton authored
      Patch from Anton Blanchard <anton@samba.org>
      
      With ppc64 64bit dynamic executables we have to relocate the contents of the
      function descriptor.  Passing in the load address to ELF_PLAT_INIT allows us
      to do this.
      
      The patch allows ppc64 to run 64-bit executables and is a no-op for other
      architectures.

      [PATCH] Fix noirqbalance · eb5ef7e6
      Andrew Morton authored
      Patch from Zwane Mwaikambo <zwane@linuxpower.ca>
      
      This patch fixes what seems to have been a longstanding bug. Ever since we
      moved cpu bringup later into the boot process, we end up programming the
      ioapics before we have any of our possible cpus in the cpu_online_map.
      Therefore leading to the following current situation;
      
      For walmart-smp, bigsmp and summit we set the logical destination for cpu
      to TARGET_CPUS which can depend on the cpu_online_map, so what you would
      normally see with noirqbalance would be all interrupts handled on cpu0
      since at that stage no other cpu apart from the BSP is online.
      
      You can check for this by looking at the ioredtbls at boottime for a two
      way system;
      
      .... IRQ redirection table:
       NR Log Phy Mask Trig IRR Pol Stat Dest Deli Vect:
       00 000 00  1    0    0   0   0    0    0    00
       01 001 01  0    0    0   0   0    1    1    39
       02 001 01  0    0    0   0   0    1    1    31
       03 001 01  0    0    0   0   0    1    1    41

       06 001 01  0    0    0   0   0    1    1    59
      
      Notice that 'Log' is set to 1 instead of 3.
      
      This patch will simply reprogram all the ioredtbls to handle the other
      online cpus.
      
      Patch tested on my 2way P2-400 and a 16way NUMAQ both with noirqbalance.
      It will not affect the irqbalance case because we are simply setting
      TARGET_CPUS which is done anyway.

      [PATCH] signal fix for wedge on multithreaded core dump · 874f2e47
      Roland McGrath authored
      This is a fix made almost a month ago, during the flurry of signal changes.
      I didn't realize until today that this hadn't made it into 2.5.  Sorry
      about the delay.
      
      This fix is necessary to avoid sometimes wedging in uninterruptible sleep
      when doing a multithreaded core dump triggered by a process signal (kill)
      rather than a trap.  You can reproduce the problem by running your favorite
      multithreaded program (NPTL) and then using "kill -SEGV" on it.  It will
      often wedge.  The actual fix could be just a two line diff:
      
      +                       if (current->signal->group_exit)
      +                               goto dequeue;
      
      after the group_exit_task check.  That is the fix that has been used in
      Ingo's backport for weeks and tested heavily (well, as heavily as core
      dumping ever gets tested, but it's been in our production systems).
      
      But I broke the hair out into a separate function.  The patch below has the
      same effect as the two-liner, and no other difference.  I have tested
      2.5.64 with this patch and it works for me, though I haven't beat on it.
      
      The way the wedge happens is that for a core-dump signal group_send_sig_info
      does a group stop of other threads before the one thread handles the fatal
      signal.  If the fatal thread gets into do_coredump and coredump_wait first,
      then other threads see the group stop and suspend with SIGKILL pending.
      All other fatal cases clear group_stop_count, so this is the only way this
      ever happens.  Checking group_exit fixes it.  I didn't make do_coredump
      clear group_stop_count because doing it with the appropriate ordering and
      locking doesn't fit the organization that code.

      [PATCH] fix affs/super.c · e54f721e
      Andries E. Brouwer authored
      Mounting a non-affs filesystem as affs crashes the kernel.
      The reason is the
      	sbi = kmalloc(sizeof(struct affs_sb_info), GFP_KERNEL);
      	memset(sbi, 0, sizeof(*AFFS_SB));
      where the second sizeof is 1, so that sbi is not zeroed at all.
      
      Also, avoid a warning for printk of sector_t in amigaffs.h.

      [PATCH] ext2: block allocation fix · 8262499b
      Andrew Morton authored
      Patch from Alex Tomas <bzzz@tmi.comex.ru>
      
      There is a logic error in ext2_new_block().  If we manage to reserve some
      blocks in the final blockgroup, local variable `bit' will be equal to
      sbi->s_groups_count and we erroneously assume that the allocation failed.
      
      Fix that up by testing local variable `group_alloc' instead.

      [PATCH] Ext2/3 noatime and dirsync fixes · 3bdfab20
      Andrew Morton authored
      Patch from "Theodore Ts'o" <tytso@mit.edu>
      
      I recently noticed a bug in ext2/3; newly created inodes which inherit
      the noatime flag from their containing directory do not respect noatime
      until the inode is flushed from the inode cache and then re-read later.
      This is because the code which checks the ext2 no-atime attribute and
      then sets the S_NOATIME in inode->i_flags is present in
      ext2_read_inode(), but not in ext2_new_inode().
      
      I fixed this in 2.4, and then found an even worse bug in the 2.5 code;
      the DIRSYNC flag is completely ignored *except* in the case where a
      directory is newly created using mkdir and its parent directory has the
      DIRSYNC flag.  S_DIRSYNC doesn't get set in the ext2_new_inode() or the
      ext2_ioctl() paths (which is used by chattr).
      
      This patch centralizes the code which translates the ext2 flags in the
      raw ext2 inode to the appropriate flag values in inode->i_flags in a
      single location.  This fixes the bug, makes things cleaner, and also
      removes 30 lines of code and 128 bytes of compiled x86 text in the
      bargain.

      [PCI] pci-15: Fix setup-bus.c resource sizing. · 18e35894
      Russell King authored
      Patch from Ivan Kokshaysky
      
      This fixes long standing typo ('size' instead of 'r_size') which causes
      overestimate of the bridge memory ranges calculated in pbus_size_mem().
      For example, if we have a device with one 1Mb and one 2Mb memory ranges
      behind the bridge, calculated size and alignment of the bridge memory
      window will be 4Mb and 2Mb respectively, while the correct values are
      3Mb and 1Mb.

      [PCI] pci-13: unuse pci_do_scan_bus() · 52e13cc2
      Russell King authored
      In an attempt to "unuse" pci_do_scan_bus() so it can be eventually
      killed, make pci_scan_bus_parented() call the new pci_scan_child_bus()
      and pci_bus_add_devices().  The only remaining callers are the
      hotplug drivers.
      
      Eventually, pci_bus_add_devices() will be removed from this function -
      it is intended that architectures should call this after they have
      done any setups and fixups to the scanned bus.
      
      It is legal to call pci_bus_add_devices() on a bus which has already
      had this function called, so architectures could update today.

      [PCI] pci-9: Kill per-architecture pcibios_update_resource() · b64958d9
      Russell King authored
      Kill pcibios_update_resource(), replacing it with pci_update_resource().
      pci_update_resource() uses pcibios_resource_to_bus() to convert a
      resource to a device BAR - the transformation should be exactly the
      same as the transformation used for the PCI bridges.
      
      pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
      set the high 32-bits to anything non-zero - currently no architecture
      attempts to do something different.  If anyone cares, please fix; I'm
      going to reflect current behaviour for the time being.
      
      Ivan pointed out the following architectures need to examine their
      pcibios_update_resource() implementation - they should make sure that
      this new implementation does the right thing.  #warning's have been
      added where appropriate.
      
      	ia64
      	mips
      	mips64
      
      This cset also includes a fix for the problem reported by AKPM where
      64-bit arch compilers complain about the resource mask being placed
      in a u32.

      [PCI] pci-8: pci_resource_to_bus() · 2ef9c88b
      Russell King authored
      Convert pcibios_fixup_pbus_ranges() into something more generic, namely
      pcibios_resource_to_bus() - we are really trying to convert resources
      to something to program into bus registers for bridge windows, and in
      fact, PCI device BARs.
      
      This is necessary since some architectures, namely Alpha, ARM and PARISC
      have an offset between PCI addressing and host-based addressing, so
      resources need to be adjusted when read or when written back to the bus.
      
      We provide a generic version in asm-generic/pci.h, which most
      architectures use.
      
      This patch finds the following architectures with something to think
      consider:
      
              - ppc, ppc64
                      adjusts resources for devices, but not buses.
      		This is inconsistent, and leads to improperly
      		programmed windows/BARs.
      
      PPC people (Anton) has a replacement PCI resource implementation
      which should do the right thing.

      Patch from Ivan Kokshaysky
      
      remove the "parent" or "root" second argument to
      pcibios_update_resource().  This highlights the following
      architectures doing something wrong in their implementation:
      
              - ia64
              - mips it8172
              - mips "generic mips boards"
              - mips64 "generic mips boards"
              - mips64 IP27

      [PCI] pci-6 - Fix scanning of non-zero functions · a9d96a6e
      Russell King authored
      Fix breakage in pci-3 - we scanned all functions if function 0 was not
      present.  This causes some host bridges to lock up when scanning devfn
      255 on PPC machines.
