The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

Replaced the _kern_null syscall with _kern_is_computer_on.
is_computer_on_fire is a bit harder, since it returns a float from kernelland, which
at the moment isn't supported in haiku.

the PPC version also does at this time).

* Added empty _klock_node_() syscall for compatibility - all R5 syscalls are now
also only compiled with GCC 2.95.
* This should fix bug #403.

* Added syscalls _kern_set_cpu_enabled() and _kern_cpu_enabled().
* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to
be a simple thread pointer instead of a struct thread_queue.
* Turns out we're monitoring CPU activity incorrectly when we've got more
than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.

The time base conversion factor is the 32 bit value
2^32 * 1000000 / time base frequency,
so the system time can be computed by
system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

now run under BeOS as well (as long as they don't use any functions that are not
available under R5).
The solution is a bit messy, but we have to live with it :-)
The runtime loader now patches the __gRuntimeLoader symbol in libroot.so to point
to its exported structure instead of passing it to the init functions as an
argument.

device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

substructure now (that's the only member actually). The system time
offset is therefore accessed via architecture specific accessor
functions.
Note, that this commit breaks the PPC build. Since I want to rename at
least one file I've already changed, I can't avoid that.

easier to define them for now, since they are used unconditionally e.g.
in the Tracker sources.

they could not be parsed again by the kernel, and thus, safemode was not working
anymore (as it was queried by the SMP stuff).

categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

to the parameters nor the number of parameters; the kernel is able to
get both without problems.
The syscall functions in libroot (_kern_*()) are now self-contained
(they don't "jmp" to separate code anymore), which at least
theoretically allows gdb to print a stack trace with the syscall
function on the top when a thread is currently performing a syscall.
Practically it doesn't work yet, though, since those functions are
frameless (i.e. create no stack frame) which needs special support
I haven't implemented yet.

went fine).

from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility,
_kfind_thread_ is retained. This will fix some compile
problems, and provides a cleaner OS.h for future Haiku
versions.

now as well.
Also, both functions will now test if the executable exists and is valid; that
way, load_image()/exec*() can catch many errors without having to create a new
team (or erase the current one - an exec*("my invalid app") might now return
with an error).
The runtime linker now exports a function to test executables that is aware
of the search paths, and will also check user permissions upfront.

can now only happen if the thread is killed.
_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.
