that an error can be propagated back to vm_soft_fault().
* Added boolean restart reference parameter to fault_find_page() which
is set to true whenever a condition is it encountered that requires
to start fault_find_page() from the very beginning. fault_get_page()
checks the flag and executes fault_find_page() in a loop, now.
* Removed the panic()s+TODOs in fault_find_page() when a cache became
busy. The restart feature is used in this case.
* fault_find_page(): If after the loop we haven't found a page yet,
and after locking the right cache one turned up, we restart the
function, too, thus avoiding double insertion of a page into a cache.
* Fixed potential dead-lock in fault_get_page(): After inserting a clean
page into a cache other than the top cache (read fault on
copy-on-write area not backed by a file (e.g. the heap)) the dummy
page was removed from the to be locked top cache while we still held a
lock for the lower cache, thus inverting the locking direction
required by the cache locking policy (top -> bottom).
* fault_get_page(): In case of a write access and a readable page found
in a lower cache, vm_cache_remove_consumer() could have replaced our
dummy page with a real page from a collapsed lower cache while we
had unlocked both caches. We didn't check for this condition and
always inserted our freshly allocated page, thus potentially inserting
a duplicate page into the top cache. We do the check now and discard our
page, when another page turned up. Fixes bug #1359.
* fault_get_page(), same if block: Removed unused case for removal of the
dummy page from a non-top cache. We only ever insert it into the top
cache and it should not be moved to another cache. Added an assert.

from the store into the top cache, which could lead to pages inserted
multiple times into the cache. We don't insert a dummy page in this case
anymore. Instead we mark a freshly allocated page busy and insert that
one. That's exactly the approach the file cache uses too. This does
probably make the whole dummy page special handling in the file cache
obsolete.

the new structure tty_settings of which there's only one instance per
master/slave tty pair. Previously the existence of two instances of those
members caused several kinds of problems, e.g. the Terminal setting
the window size on the master and CLI programs readings the unchanged
values from the slave. E.g. less correctly adjusts the display when the
Terminal size changes, now.
* Reorganized writing to a TTY. We do no longer handle writes to master
and slave the same way. Writes to the master are "input" and need to
be processed differently from writes to the slave ("output"). Before,
both were processed first as output then as input, which caused incorrect
behavior. E.g. CRs were not echoed correctly.
* Added canonical ERASE (backspace) and KILL (clear line) processing.
Couldn't really see it work. glibc's fgets() seems to read single
chars, so that we never have anything in the line buffer.
* Added handling for EOF. Works well with Be's Terminal, ours seems to
write an ESC sequence instead of the EOF char (Ctrl-D), though.
* Extended output processing support (ECHOE, ECHOK, ECHONL, OCRNL,
ONLRET, OLCUC).

* More conditional debug code (wrt page transitions between caches).
* Replaced debugger command cache_chain by a nicer cache_tree.
* While handling a soft fault: When we temporarily unlock a cache, it
can theoretically become busy. One such occurrence is now handled
properly, two more panic() ATM, though should be fixed.
* When merging caches, we do now always replace a dummy page in the
upper cache, not only when the concurrent page fault is a read fault.
This prevents a page from the lower (to be discarded) cache from still
remaining mapped (causing a panic).
* When merging caches and replacing a dummy page, we were trying to
remove the dummy page from the wrong cache (causing a panic).
The Haiku kernel seems now to run shockingly stable. ATM, we have more
than two hours uptime of a system booted and running over network. We

* Refactored RescanDiskSystems(). Pulled out a function
_RescanDiskSystems() that scans for either file or partitioning
systems. RescanDiskSystems(), which scanned for file systems only
before, is used from the constructor as well (open_module_list()
works in the early boot process since a while).
* Made InitialDeviceScan() and partition scanning safe to be called a second
time. We call it directly after the kernel has mounted the boot
volume, now, so that additional disk systems from the boot volume have a
chance to recognize previously unrecognized partitions. This is a
temporary change only; later the disk device manager shall
automatically find out when new disk systems/devices/whatever are
available.

* Images preloaded by the boot loader had to be modules to be of any use
to the kernel. Extended the mechanism so that any images not accepted
by the module code would later be tried to be added as drivers by the
devfs. This is a little hacky ATM, since the devfs manages the drivers
using a hash map keyed by the drivers inode ID, which those drivers
obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
doesn't implement the former (all old-style drivers), thus making it
possible to BFS, which uses the file cache which in turn requires
read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
more flexibly be extended and deals more gracefully with
arbitrarily-size data. The disk_identifier structure still exists,
though. It is added as message field in cases where needed (non net
boot). Moved the boot_drive_number field of the bios_ia32 platform
specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
initialization code into the stage 2 loader, which can now be loaded
directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
does no longer use the RemoteDisk protocol (it could actually be
removed from the boot loader). It also parses the DHCP options in the
DHCPACK packet provided by PXE and extracts the root path to be
mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
added support for network boot. In this case the net stack is
initialized and the network interface the boot loader used is brought
up and configured. Since NBD and RemoteDisk are our only options for
net boot (and those aren't really configurable dynamically) ATM, the
the boot device is found automatically by the disk device manager.
Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

pages living in the identity mapped region, which they wouldn't, when

The idea is to directly built the boot archive into the boot loader for

of the NBP. Maybe Open Firmware is less restrictive.
