- Update to 4.1.0
  o Fix "extend" regression on s390x and x86, introduced in crash 4.0.9
    with the "-x" option
  o Cleanup top-level source files to address compiler warnings
    generated by the CFLAGS used in the Fedora build environment
  o Fix "pte" on s390 and s390x if the pte value argument evaluates as
    not present
  o Allow command redirection to pipes or files when using gdb commands 
    alone on the command line without preceding it with "gdb"
  o Fix the processing of bit fields on big endian systems in the SIAL
    extension module
  o Fix "dis -l" to properly display line-number information for 2.6.21
    and later x86_64 kernel module text addresses
  o Prevent querying the embedded gdb module for line numbers of kernel
    module text addresses if the module's debuginfo data has not been loaded
  o New option "ps -G" to restrict the process status output to the thread
    group leader of a thread group
  o Several fixes for the "repeat" command when used in conjunction
    with an input file.  Without the patch:
    - Depending upon the command executed from the input file, a SIGINT
      would kill the command currently being executed from the input file,
      but the "repeat" command would then restart it.
    - If a command in the input file redirected its output to a pipe, the
      repeat operation could stop prematurely after executing that particular
      command.
    - If a command in the input file redirected its output to a pipe, the
      zombies of the command being piped to would not be cleaned up until the
      repeat command was stopped.
    - If the last command in the input file redirected its output to a pipe,
      all subsequent executions of the input file would only display the
      output of that last command.
  o New extension: "trace.so"
  o Fix for a potential failure to initialize the kmem slab cache 
    subsystem on 2.6.22 and later CONFIG_SLAB kernels if the dumpfile
    has pages excluded by the makedumpfile facility
  o Fix a potential session initialization failure on x86_64 kernels
    if the dumpfile has pages excluded by the makedumpfile facility
  o Fix "kmem -z" on 2.6.29 and later kernels
  o Fix "irq" on 2.6.29 and later CONFIG_SPARSE_IRQ kernels
  o Fix "kmem -i" on 2.6.31 kernels
  o Fix "kmem -i" on x86_64 running 2.6.26 through 2.6.30
  o Fix "kmem -p" on older 64-bit kernels that have a 32-bit page.flags field
  o Fix "kmem -i" on older kernels whose unreferenced page.count value was -1
    (instead of 0)
  o Change the cursor location when cycling through the command history
    in "vi" editing mode (the default)

- Update to 4.0.9
  o New mainline versioning
  o Wholesale replacement of the x86/x86_64 disassembly code in the
    embedded gdb-6.1 module to that used in gdb-6.8 to correctly decode
    the 5-byte NOP used by the function tracer
  o Fix compressed diskdump/kdump vmcores to properly handle page
    descriptor structures that are located beyond a 4GB file offset
    in the vmcore file
  o Fix the "sym <address>" command option when the address references
    a symbol in the vsyscall FIXMAP virtual address page in certain
    x86_64 kernel versions
  o Multiple fixes for the "bt" command on x86_64:
    - properly recognize vsyscall FIXMAP virtual addresses when
      encountered as the RIP in an exception frame.
    - always use the NMI exception stack when available, not the per-cpu
      IRQ stack of an active non-crashing task
    - correctly determine the frame just above an IRQ interrupt exception
      frame, or above an exception frame that gets handled on the process
      stack, such as a page fault
    - correctly calculate the frame size to differentiate between text
      return addresses and the precise text RIP address of an exception
  o Fix usage of a System.map file argument with 2.6.30 and later kernels
    to avoid "crash: symbol count overflow (trace_kmalloc)" messages
  o Fix usage of a System.map file argument whose symbol list does not
    contain an "_end" symbol.
  o Fix "kmem -p <address>" or "kmem <address>" when <address> is not
    a page structure address to avoid the annoying "kmem: WARNING:
    sparsemem: invalid section number: 8192" messages
  o Fix the snap.so extension module when run on pre-2.6.31 x86_64
    kernels with more than 4GB of physical memory
  o Fix build of the snap.so extension module on older systems
    running with "make" versions 3.80 or earlier
  o Fix build of the sial.so extension module if /usr/bin/bison
    and /usr/bin/flex do not exist on the host build system
  o Fix for the "rd" and "vtop" commands on RHEL4 x86_64 Xen paravirtual
    kernels in the reading or translation of vmalloc addresses that are 
    not in kernel module vmalloc address space
  o New command line option "-x" to automatically load extension modules

- Update to 4.0-8.12
  o Support for the KVM "save-vm" file format
  o Support for 2.6.30 and later x86 CONFIG_4KSTACKS kernels, where
    hardirq_ctx[] and softirq_ctx[] arrays were changed to per-cpu
  o Replace the CFLAGS definition in the Makefile with a CRASH_CFLAGS
    definition, which in turn contains ${CFLAGS} to allow user-defined
    CFLAGS on the "make" command line
  o Bail out with a "not a supported file format" error immediately
    when trying to open x86 vmlinux file on an x86_64 host
  o Fix the "bt" command on x86 Xen hypervisor dumpfiles where a vcpu
    received a shutdown NMI while running in an interrupt handler
  o Correct cpu accounting when processors have been taken offline
    using a new get_highest_cpu_online() utility function
  o Fix a segmentation violation when running against kernels built
    with Fedora gcc version 4.4.0-12 and later, which introduced
    a more compact Dwarf 3 DW_AT_data_member location
  o Clean up gdb header files that generate warning messages when 
    compiling the top-level cmdline.c file with "make warn" or 
    "make Warn"
- Delete crash-4096-cpus-x86_64.diff: Mainline.

- Update to 4.0-7.7
  o Dynamic page size detection on PPC64 and IA64.
  o Fix for "mod -[sS]" command if the target module object
    filename contains both underscore and dash characters.
  o Reject s390 and s390x "L2^B" local label symbols from the
    kernel symbol list.
  o Enlarge the string format buffer in the show_last_run()
    function to prevent a buffer overflow when running "ps -l".
  o Fix for "bt -a" to continue with the backtraces of the
    remaining active tasks when one of them encounters a fatal
    error.
  o Only allow trusted versions of .crashrc and .gdbinit files to
    be sourced during session initialization.
  o Fix for a potential but highly unlikely buffer overflow in the
    gdb dwarfread.c and dwarf2read.c files, which requires a hand-
    crafted object file with a location block (DW_FORM_block) that
    contains a large number of operations.
  o Fix for a potential but highly unlikely integer overflow in the
    Binary File Descriptor (BFD) library, which requires a hand-
    crafted object file that that specifies a large number of
    section headers, leading to a heap-based buffer overflow.
  o Enable stack unwind on ia64 when using a kerntypes file as the
    kernel namelist.
  o Fix for failure of "files -R" command option if an inode is
    unknown due to a NULL f_dentry pointer in any open file
    structure because of a kernel error condition.
  o Allow an LKCD kerntypes debuginfo file created from a kernel
    module to be loaded with the command:
    "mod -s <module> <kerntypes-file>".
  o Increased NR_CPUS from 256 to 512 for x86_64, and from 128 to
    1024 for ppc64.

- Don't build on 32 bit PPC to prevent distribution of 32 bit
  PPC packages. Since kdump doesn't exist on ppc and crash-ppc
  cannot read ppc64 (ELF64) dumps, such a package doesn't have
  any practical benefit.

- crash-pagesize.diff: Polish for mainline inclusion.
  o Remove the ia64 part that is responsible for dumps that
    are in ELF format and have no VMCOREINFO.

  o Fix for "kmem -i" and "kmem -p" on 2.6.26 x86 CONFIG_SPARSEMEM
    PAE kernels to account for the change in value of
    SECTION_SIZE_BITS.
  o Fix for "bt -[tT]" options on x86 architectures when the
    backtrace starts on the hard IRQ stack.
  o Fix for the "bt" command when run on a xen hypervisor in which
    the backtrace leads to either "process_softirqs" or
    "page_fault".  
  o Fix for the "kmem -[sS]" options that could cause a
    segmentation violation or bogus "bad slab pointer" and "bad
    inuse counter" error  messages.
  o Fix for a bug in the SIAL extension when dealing with
    bitfields.
  o Fix for the "files" command when run on 2.6.25 and later
    kernels,  which would either fail with an "invalid kernel
    virtual address" error of type "fill_dentry_cache", or would
    show nonsensical/garbage "ROOT" and "CWD" pathnames.
  o Addition of a new "null-stop" environment variable that can be
    turned on/off with the "set" command.
  o Fix for the builtin "g" alias, which would fail with an
    "Ambiguous command" error from the embedded gdb module.  
  o Fix to handle the 2.6.27 kernel's change of the module
    structure's num_symtab, core_size and core_text_size members
    from long to int.
  o Implement support for the /dev/crash driver being built into
    x86 or x86_64 Red Hat kernels with the restricted /dev/mem
    driver.
  o If the /dev/crash driver module has been loaded prior to a live
    crash session, then it will not be unloaded when the crash
    session exits.
  o Fix to recognize the 2.6.25 re-naming of the x86
    user_regs_struct structure members.
  o Fix for initialization-time failure when running against 2.6.27
    x86_64 xen kernels, which indicate "crash: cannot resolve:
    end_pfn".
  o Fix for initialization-time failure when running against Xen
    4.4  hypervisor binaries, which indicate "crash: invalid
    structure member offset: domain_is_polling".
  o Added a new "p -u" option, which indicates that the gdb
    expression argument evaluates to a user virtual address in the
    current context.
  o Fix for "bt -a" command when running against the xen hypervisor
    where the number of physical cpus outnumber the MAX_VIRT_CPUS
    value for the processor type.
  o Fix for the display of the processor speed on IBM Power6
    hardware.
