switch /boot to a different volume in two operations, unless you have first
linked /system/lib into /bin. This patch assumes that / will always have the
ID 1. Don't know if that is proper. Note that I also thought about solving
this in the VFS, since perhaps it isn't the job of root-fs to know about
/boot, but that would of course introduce another check for every rename
operation, which I decided against.

Seems like we didn't remember to change it back, even
with the #warning. :-)
I tested ftp and it works fine. This also closes ticket #4176.

* Moved device_manager/settings.cpp to debug/safemode_settings.cpp.
* Removed the somewhat hacky concatenation of kernel settings and safemode
settings in the boot loader. Instead, get_safemode_option() will now fall
back to the kernel settings, if it couldn't spot a setting in the safemode
settings. This allows for more control, and also makes enabling serial
debug output actually work (ie. overriding the kernel settings via safemode
options).
* Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use
get_safemode_boolean().
* Therefore, I added safemode_settings.cpp to the boot loader as well.

So either +alphabranch or remove the declarations from <dirent.h>.

into the scope of the lock. Saves an InterruptsSpinLocker.
* Use an InterruptsSpinLocker() as in other places.
* When creating/forking a team fails because the kernel thread cannot be spawned
balance the already sent TEAM_ADDED notification by sending a TEAM_REMOVED one.

been removed. That includes CPU disabling and thread pinning, as that becomes
pointless with only one CPU.
* Return a proper reschedule hint on enqueing a thread, based on the priority
of the current thread vs. the enqueued one.
* Enable dynamic scheduler selection. With one CPU the simple scheduler will
be used, otherwise affine is selected.
* Removed the scheduler type define as we now always auto-select it.
* Some cleanup.

* scheduler_enqueue_in_runqueue() now allows the scheduler to return a hint as to whether a reschedule is desirable or not. This is used in a few other places in order to relegate scheduling decisions entirely to the scheduler rather than the priority hacks previously used. There are probably other places in the kernel that could now make use of that information to more intelligently call reschedule() though.
* Switch over the default scheduler to scheduler_affine().

you can easily produce a dead lock. This should fix the system hang
experienced as part of bug #4223.

* Keep track of the currently running threads.
* Make use of that info to decide if a thread that becomes ready should preempt
the running thread.
* If we should preempt we send the target CPU a reschedule message.
* This preemption strategy makes keeping track of idle CPUs by means of a bitmap
superflous and it is therefore removed.
* Right now only other CPUs are preempted though, not the current one.
* Add missing initialization of the quantum tracking code.
* Do not extend the quantum of the idle thread based quantum tracking as we want
it to not run longer than necessary. Once the preemption works completely
adding a quantum timer for the idle thread will become unnecessary though.
* Fix thread stealing code, it did missed the last thread in the run queue.
* When stealing, try to steal the highest priority thread that is currently
waiting by taking priorities into account when finding the target run queue.
* Simplify stealing code a bit as well.
* Minor cleanups.

re-insert it at a new place, but by only setting the priority and not the
next_priority field, the thread would actually be enqueued at the same priority
level as before. Didn't cause any real damage, guess it was just an oversight.

not hold the bin lock while setting and only protect the actual freeing. May
reduce bin lock contention a little bit.
* Tiny optimization for force-clearing 0xdeadbeef. Do it after setting to 0xcc,
so that it's less likely we have to do it.

* Always select POLLNVAL. We wouldn't get notified, if the FD was closed while
waiting.
* Skip negative FDs (as per POSIX standard).
* When encountering an invalid FD, we must not wait. Previously we did that as
long as any FD was valid.
* The return count must consider all FDs with non-null revents, including
invalid ones (revents is POLLNVAL then).
common_poll()/common_wait_for_objects():
* Don't bail out early, when no FDs/objects have been selected. We always want
to wait.
_user_poll()/_user_wait_for_objects():
* Copy the array back to userland even if common_*() returned an error. The
functions do now always fill in the resulting events.

* B_EVENT_INVALID is no longer passed to the FD's select()/deselect() hooks.
* Now we always attach the select info to the I/O context, even if no event has
been selected. The reasoning is that B_EVENT_INVALID is always automatically
selected and handled by the VFS, so we need the handle to notify on close().

This seems to work around the dynamic segment having a huge file size in headers, it must also be in the data segment...

Add support for boot splash, only for PXA.
Disabled for now as it forces the framebuffer onto some useful data.

instead of using the user buffer. This frees the VFS and FS implementations
from handling user buffers.
* Adjusted fix_dirent() accordingly.
