While this should allows larger logo/icons, it doesn't remove the

* The team and thread kernel structures have been renamed to Team and Thread
respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
private kernel headers are included that are no longer C compatible.
Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).

that's the limit of the addr_t domain anyway.

- 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 ;)

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.

Add support for both discovery and regular iSCSI sessions. Command and status
sequence numbers do differentiate between session and connection but only
one connection per session is currently supported.
Code is Big Endian for now, so compile it for ppc only.

Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.
The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.
Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.
Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

* _kern_[sg]et_timezone() now accepts/passes out the timezone name, too
* adjust Time preflet and clockconfig to pass the timezone name into the kernel
when calling _kern_set_timezone()
* ajust implementation of tzset() to fetch the timezone name from the kernel
via _kern_get_timezone() instead of reading 'libroot_timezone_info'

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37905 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37888 a95241bf-73f2-0310-859d-f6bbb57e9c96
* renamed syscalls _kern_[gs]et_tzfilename
to _kern_[gs]et_real_time_clock_is_gmt, as the filename part is no longer
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

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.

- Takes a physical_address_restrictions instead of base/limit and also

* DMAResources:

- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

map_backing_store() doesn't commit memory when this flag is given.
* Used the new flag vm_copy_area(): We no longer commit memory for read-only
areas. This prevents read-only mapped files from suddenly requiring memory
after fork(). Might improve the situation on machines with very little RAM
a bit.
We should probably mark writable copies over-committing, since the usual
case is fork() + exec() where the child normally doesn't need more than a
few pages until calling exec(). That would significantly reduce the memory
requirement for jamming the Haiku tree.

* Moved the B_OVERCOMMITTING_AREA flag from B_KERNEL_AREA_FLAGS to
B_USER_AREA_FLAGS, since we really allow it to be passed from userland.
* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
instead of B_USER_PROTECTION, now. This way they allow for
B_OVERCOMMITTING_AREA as well.
* _user_map_file(), _user_set_memory_protection(): Check the protection like
the other syscalls do and use fix_protection() instead of doing that
manually.

boot CPU wait until all other CPUs are ready to wait. This solves a
theoretical problem in main(): The boot CPU could run fully through the early
initialization and reset sCpuRendezvous2 before the other CPUs left
smp_cpu_rendezvous(). It's very unlikely on real hardware that the non-boot
CPUs are so much slower, but it might be a concern in emulation.

free respective free and cached pages.
* Removed the unused vm_page_allocate_page_run_no_base().
* vm_page_allocate_page_run() (and allocate_page_run()):
- Use vm_page_reserve_pages() instead of vm_page_try_reserve_pages(), i.e.
wait until the reservation succeeds.
- Now we iterates two times through the pages to find a suitable page run. In
the first iteration it only looks for free/clear pages, in the second
iteration it also considers cached pages. This increases the chance of the
function to succeed, when a lot of caching is going on.
This reduces the amount of memory required to use the IOCache when booting
off the anyboot Live CD to around 160 MB in qemu. It also seems to work with
128 MB, but the syslog indicates that some memory allocations fail, which
is not exactly inspiring confidence.
