      [PCMCIA] pcmcia-8/9: Clean up CIS setup. · 00dbc966
      Russell King authored
      - Re-order functions in cistpl.c.
      - Combine setup_cis_mem and set_cis_map into one function.
      - Move cis_readable(), checksum() and checksum_match() into rsrc_mgr.c
      - Only pass the socket structure to validate_mem()
      - Remove socket_info_t *vs variable, and the race condition along
        with it.
      - Pass the socket_info_t through validate_mem(), do_mem_probe() and
        inv_probe() to these functions.
      - Call cis_readable() and checksum_match() directly from
        do_mem_probe().

      Just an obvious fix.
      The kiocbClearX macros were doing a set_bit !
      They should be calling clear_bit.
      Ran into this now that I'm actually using kiocbClearKicked.

      [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.

      Patch from Anders Gustafsson <andersg@0x63.nu>
      
      We're getting a division-by-zero in the writeback code during early rootfs
      population, because writeback has not yet been initialised.
      
      Fix that by performing an explicit initialisation rather than relying on

      [PATCH] Fix mem= options · 585c3653
      Andrew Morton authored
      Patch from "Randy.Dunlap" <rddunlap@osdl.org>
      
      Reverts the recent alteration of the format of the `mem=' option.  This is
      because `mem=' is interpreted by bootloaders and may not be freely changed.
      
      Instead, the new functionality to set specific memory region usages is
      provided via the new "memmap=" option.
      
      The documentation for memmap= is added, and the documentation for mem= is
      updated.

      [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.

      This removes/fixes a few whitespaces and removes the MAX_PRIO setting in

      [PATCH] sched-2.5.64-bk10-C4 · 51d38a67
      Ingo Molnar authored
      This fixes a fundamental (and long-standing) bug in the sleep-average
      estimator which is the root cause of the "contest process_load" problems
      reported by Mike Galbraith and Andrew Morton, and which problem is
      addressed by Mike's patch.
      
      The bug is the following: the sleep_time code in activate_task()
      over-estimates the true sleep time by 0.5 jiffies on average (0.5 msecs
      on recent 2.5 kernels).  Furthermore, for highly context-switch
      intensive and CPU-intensive workloads it means a constant 1 jiffy
      over-estimation.  This turns the balance of giving and removing ticks
      and nils the effect of the CPU busy-tick, catapulting the task(s) to
      highly interactive status - while in reality they are constantly burning
      CPU time.
      
      The fix is to round down sleep_time, not to round it up.  This slightly
      under-estimates the sleep time, but this is not a real problem, any task
      with a sleep time in the 1 jiffy range will see timekeeping granularity
      artifacts from various parts of the kernel anyway.  We could use rdtsc
      to estimate the sleep time, but i think that's unnecessary overhead.
      
      The fixups in Mike's scheduler patch (which is in -mm8) basically work
      around this bug.  The patch below definitely fixes the contest-load
      starvation bug, but it remains to be seen what other effects it has on
      interactivity.  In any case, this bug in the estimator is real and if
      there's any other interactivity problem around then we need to deal with
      it ontop of this patch.
      
      This bug has been in the O(1) scheduler from day 1 on basically, so i'm
      quite hopeful that a number of interactivity complaints are fixed by
      this patch.
