b2acbcbfb3 CID 8122, 2210 (pointing at the same), 8121 and 2209 (pointing at the same):
Taking the size of a pointer instead of the actual extended registers struct.
Not sure this is used, but if it is it made the whole fpu/sse state in the
debugger useless.

d2bf328d72 Implemented a generic system watching mechanism with a userland API. Currently
only a few events can be watched (team creation/deletion/exec, thread creation/
deletion/name changes). The functions start_system_watching()/
stop_system_watching start/stop watching events.

2d8d1cdbaa * Implemented a generic way to associate data with a team which is
automatically cleaned up when the team is deleted: Class AssociatedData is
  the base class for a data item, AssociatedDataOwner a container for them
  (struct team derives from it). Functions team_associate_data() and
  team_dissociate_data() add/remove data.
* Turned sTeamHash into a BOpenHashTable (necessary since struct team is no
  longer a POD).

38eb09a376 Fixed regression introduced by r38409: For a parameterless escape sequence
process_vt100_command() would be invoked with argument count 1 (instead of 0).

c9a4637342 * ARM: Initial stab at fixing ELF relocations (much more to do though for full ELF relocation support).

c917cd6261 * ARM: Major VM work
- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
		1) It is the most complete VM arch
		2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
		   and this infrastructure has proven to be ready ;)
	- No protection features, or dirty/accessed tracking yet
	- Lots of #if 0

	but....

	It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

	Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
	when it happens, and I can actually debug from there ;)

13b81a3b8e * Added new thread flag THREAD_FLAGS_SINGLE_STEP, which is set to indicate that
userland single-stepping is enabled for the thread.
* x86_exit_user_debug_at_kernel_entry(): Always store DR6 and DR7 in the CPU
  structure, not only when breakpoints are installed.
* x86_handle_debug_exception(): When encountering a syscall single-step, also
  set the THREAD_FLAGS_DEBUG_THREAD thread flag. Otherwise the
  B_THREAD_DEBUG_STOP would be ignored.
* x86 interrupt handling, DISABLE_BREAKPOINTS():
  - Renamed to STOP_USER_DEBUGGING().
  - Now it also call x86_exit_user_debug_at_kernel_entry() when
    THREAD_FLAGS_SINGLE_STEP is set, so that the debug registers are saved.

Fixes #6751.

31bce16715 ppc: Keep memory mappings set up by OpenFirmware
Revert r36886 and fix compilation of insert_virtual_range_to_keep().
The use of void* vs. addr_t matches the surrounding boot loader code
but should probably be revised in favour of addr_t.

create_area() in the kernel wrongly assumed a RAM-backed address range,
which was destined to fail since ranges below the kernel address space
were ignored anyway. Use vm_map_physical_memory() instead.

This fixes a hang once the frame buffer and other resources used by OF
get unmapped. Closes ticket #5193 again.

3426ce1404 * Thanks to Janito I had a closer look to cache_detach_sub_transaction(), and it
turned out it's pretty much broken. Not only did it potentially leak memory,
  it would also potentially replace the original data with a NULL pointer,
  making the current transaction non revertable. The code should now be much
  clearer. This fixes bug #6378.
* Changed a few "if (... != NULL)" into ASSERTs, since the code should bail out
  earlier in these cases already.
* Added a TODO comment to cache_start_sub_transaction() about its broken discard
  handling. This can cause FS corruptions in case the parent transaction is ever
  going to be aborted (which shouldn't happen in real life, though).
* Added a bit more and better comments.

7e965f506d More consolidation of timezone code:
* dropped DaylightSavingTime from real_time_clock code in kernel, it was
  never really being used for what it meant (and just being referred to by
  gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers 
  accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
  being referred to by the FAT add-on and that one (like gettimeofday()) put a
  different meaning to tz_minuteswest. Added a comment to FAT's util.c
  showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
  timezone - it was using wrong values before, anyway.

  relevant (and the two corresponding parameters were removed)
* C++-ified and reworked clockconfig to use the info from 'Time settings' 
  to setup the timezone info during boot
* removed invocation of _kern_get_tzfilename() from tzset(), as the syscall
  no longer exists and tzset() is currently broken anyway
* adjusted the Time preflet to use the renamed syscall when getting/setting 
  the RTC info

61729d9323 * Reworked the complete stack to allow more than one address per network
interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
  complete, though, InterfaceAddresses need to hold references to their
  interface as well).
* There are two known regressions of this commit that I will fix later:
  - you cannot remove interfaces anymore
  - IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
  not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
  the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
  is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
  set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
  available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
  anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
  belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.

3aea1d4f53 * Added ObjectCache::alignment, the object alignment and used the alignment for
incrementing the cache color cycle. Using the fixed value (8) would
  potentially misalign the object again.
* Don't use CACHE_ALIGN_ON_SIZE for object caches any longer -- we have the
  alignment parameter anyway (the flag is still used for the MemoryManager,
  though).
* ObjectCache::InitSlab(): Slab coloring *was* done when CACHE_ALIGN_ON_SIZE
  was given, i.e. exactly the wrong way around. Also the cache_color_cycle
  computation was weird -- color 0 was used twice in a row.
* The "slabs" and "slab_cache" KDL commands also print the alignment, now.

44db70a313 * Resolved TODO: Use an object cache for the thread structure alloction.
* Align the allocated objects to 16 byte. This is required by the x86
  arch_thread structure. Haiku only didn't crash and burn since the until
  recently used heap allocator apparently aligned the structures to 16 byte
  anyway and the now used slab allocator has a bug preventing slab coloring
  for that object size.

b944766870 * Moved the vm_page initialization from vm_page.cpp:vm_page_init() to the new
vm_page::Init().
* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
  contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
  used to request a special handling for wired pages. If given the wired pages
  are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
  - We don't need to do any wired ranges handling, if the source area is a
    B_SHARED_AREA, since we don't touch the area's mappings in this case.
  - We no longer wait for wired ranges of the concerned areas to disappear.
    Instead we use the new vm_copy_on_write_area() feature and just let it
    copy the wired pages. This fixes #6288, an issue introduced with the use
    of user mutexes in libroot: When executing multiple concurrent fork()s all
    but the first one would wait on the fork mutex, which (being a user mutex)
    would wire a page that the vm_copy_area() of the first fork() would wait
    for.

7656ad6be1 kernel_ppc: Use saved register state for stack trace of current thread
Suggested by Ingo in ticket #6139. This shortens the stack trace and makes it
independent of whether called implicitly on KDL entry or manually from the
kernel debugger prompt.

For a kernel panic, "panic" is now the top-most frame printed.

Closes ticket #6160.

b62981b983 OpenFirmware: Make of_milliseconds() return error
The only user of of_milliseconds(), the boot loader's system_time(),
checks for an error that would never be signalled since the zero-initialized
number of milliseconds would always be returned.

Return OF_FAILED instead to allow explicit error handling in that case.

While this is a behavioral change, it is not yet a functional change,
for system_time()'s implementation translates OF_FAILED back to zero currently.

Resolves part of ticket #6061.

In r33670 the svn:eol-style property was dropped, which took care of

src/system/boot/loader/
src/system/boot/loader/net/

This avoids patches containing irrelevant lines unintentionally converted.
