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).

bus, and time base frequency) in the PPC boot loader, and propagate
them to the kernel via kernel_args.
* Now we use the correct time base frequency for timer calculations.
* Implemented PPC specific system info stuff. Added a few PPC CPU
types to <OS.h>.

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.

Return type of thread_func is now status_t instead of the previous int32.
Added some more cpuid_info fields - many fields aren't just reserved anymore.
"sysinfo" now supports the extended features of Intel CPUs, and also knows
the "HTT" bit of the standard features indicating the hyper-threading capability.

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.

_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.

they are public now, they might become private later on.
It's almost the same as acquire_sem() but allows you to release another semaphore
atomically. This makes condvar implementations and the like very simple to do.
Added B_CHECK_PERMISSION flags to the user calls, although it's not honored yet.

Most of the debug events had their own message, but some were grouped
into this `stopped' message with a `why' field to describe what kind
of event it actually was. Hence the user had to check two levels until
they could know what event occurred. So I got rid of this message and
provided separate messages for the concerned events.
* Got rid of B_DEBUG_MESSAGE_GET_WHY_STOPPED and introduced
B_DEBUG_MESSAGE_GET_CPU_STATE which is pretty much the same.
* Put B_DEBUG_MESSAGE_RUN_THREAD and B_DEBUG_MESSAGE_STEP_THREAD into
a single B_DEBUG_MESSAGE_CONTINUE_THREAD message with a boolean
`single_step' field.
* get_debug_why_stopped_string() -> get_debug_message_string().

get_debug_exception_string() to get a user-readable string for an
exception type.
* Added more signal support. Now the debugger can set per thread which
signals it wishes to be notified of. It can also just ignore the next
occurrence of a signal.

Otherwise it returns before the loader starts.

any more messages from the debugged team. The mechanism is completely
transparent to the target debugger. It simply installs itself as debugger
for the team.

translation for the debug_why_stopped codes.
* Added nub_port member to debug_origin structure, so that now all
synchronous messages to the debugger also include the debug nub port.

* team debug flags:
- Added flags for team creation, thread events (creation,
deletion), and image events (creation, deletion).
- Got rid of B_TEAM_DEBUG_SYSCALL_FAST_TRACE. We always send the syscall
arguments. The overhead should be neglectable.
- Added B_TEAM_DEBUG_STOP_NEW_THREADS.
* Added debugger notification messages for signals, team, thread and
image events.
* Added debug request B_DEBUG_MESSAGE_GET_WHY_STOPPED.
* When continuing a thread, the debugger can now specify how to deal with
the occurred event (ignore or handle).
* More data in the signal received notification message.

Unless a good reason appears not to, we'll break binary compatibility here.
BDB could be considered one, but we need a replacement for it anyway. We
strive to port GDB and a couple of changes in the debugger API will make
that easier.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11307 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed ARM support.

* Added structure and constants for pre syscall tracing.

it does belong to <KernelExport.h> anyway.
* Reverted the protection flags back to decimal for consistency with the
other places. BTW, since when do we use decimals for flags?

not how it is declared in R5, but it is what actually is returned.
* Temporarily added debug_[v]printf() functions for userland usage,
equivalent to dprintf() in kernel.

- Removed the OBOS_CPU_TYPE stuff - our types are now always defined.
- Made the cpu types consistent, renamed X86 to x86.
- cpuid_info.eax_1 now also contains the extended family/model info.
- Renamed cpuid_info.eax_0.vendorid to vendor_id.
- changed B_CPU_x86_VENDOR_MASK to 0xff to make some space for future changes.
- added some more CPU types (if anyone knows more Transmeta IDs; I
couldn't find more of them).

there is no reason to let it appear important by having it as first

so choses.

may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
(the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.

*_volume().
Added a "volumeName" parameter to the fs_initialize_volume() call.
Introduced a "flags" field to the fs_unmount_volume() call - I have only
defined one flag, B_FORCE_UNMOUNT, right now.
But the unmount behaviour should be discussed anyway first (always force
unmount?).

Since BFS can't resolve a vnode_id to an attribute, fs_create_attr() now
doesn't return a new vnode_id anymore. Changed all fs_vnode variables to
"file" instead of "attr" to avoid any confusion.
That means for BFS that the cookie which fs_open_attr() returns will have
to include a pointer to the real inode, if the attribute is not part of the
file's inode.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1118 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added syscalls for, and implemented sys_create_link(), sys_remove_dir().
Implemented link(), unlink(), rmdir().
Fixed the inconsistent path buffer handling in the user|sys vfs functions; the
path buffer is now exactly SYS_MAX_PATH_LEN from userland (incl. terminating
null byte).

- added needed syscalls to access symlink support from userland
- implemented lstat(), symlink(), and readlink()
- added dev_t to ktypes.h (for now - should be in a public header anyway)
- added symlink support to the "ls" command (now calls lstat() and shows the
link target with the -l option)
- changed the sys_read_stat() call to support symlinks, and updated files
using that function (it gets an extra argument: bool traverseLink)

sys_read_dir() now has a parameter for the maximum number of dirents that
