* process.c (process_lookup_kernel_symbol): Add support for
looking up kernel symbols from /proc/kallsyms
* sysprof-text.c (dump_data): Print note that the file is being
saved.
* module/sysprof-module.[ch] (timer_notify): Send a copy of the
kernel stack to userspace.
* collector.c: Do kernel symbol lookups.

2006-10-26 Soren Sandmann <sandmann@daimi.au.dk>
* module/sysprof-module.h (struct SysprofStackTrace): Increase the
max number of addresses to 1021, reorganise SysprofMmapArea to
make the traces naturally page aligned.
* TODO: Update
2006-10-22 Soren Sandmann <sandmann@daimi.au.dk>
Communicate traces to userspace through shared memory instead of
copying.
* module/sysprof-module.c: Store the traces in a SysprofMmapArea.
(sysprof_mmap): Implement this method.
(sysprof_nopage): Implement this.
(sysprof_read): Just reset the tail pointer and return zero.
* module/sysprof-module.h (struct SysprofMmapArea): New
structure.
* collector.c (collector_stop): Unmap the device
(in_dead_period): New function
(on_read): Read the traces out of mmap()ed area instead of reading
them. Call read() to prevent poll() from firing.
(struct Collector): New members map_area and current.
* Makefile.am (insert-module): Prefix modprobe with /sbin
* collector.c (open_fd): mmap() the sysprof device.
2005-12-20 Kristian Høgsberg <krh@redhat.com>
* Makefile.am: Dist and install udev rule.
* collector.c: (open_fd):
* sysprof-text.c: (no_module):
* sysprof.c: (on_start_toggled): Update device filename.
* 60-sysprof.rules: New udev rule file to set permissions for
sysprof char device.
* module/sysprof-module.c: Switch kernel module to use a misc char
device instead. Start and stop the timer on device open and
close instead of module load and unload.

* TODO: Updates
* configure.ac: Check for Linux 2.6.11
* process.c (get_pidname): Present pid=-1 as [kernel].
* module/sysprof-module.c: Use register_timer_hook() instead of
a kernel timer. Set trace.pid to -1 if interrupt happens in
kernel.

Auto*ify.
* TODO: updates
* AUTHORS, INSTALL, Makefile.am, NEWS, configure.ac: New files
* module/Makefile: New file
* module/sysprof-module.c, module/sysprof-module.h: Move these
files to their own directy, as the kernel build system does not
work very well with auto*.
* sysprof.c, autogen.sh: Some auto* changes.
