the x86 protection model to page level protection only. It's currently needed
for BeOS compatibility, though we might want to get rid of it later. Thanks
to Jerome for stombling into this :)
arch_vm_translation_map_init_post_sem() did not return a proper status.

offset to recognize the boot volume.
This should work well enough for now (as long as you don't have too many
disks in your system).

- added user data pointer to cache_transaction notifier
- added functions block_cache_set_dirty(), and block_cache_make_writable()
- cache_transaction_next_block() let's you iterate over all blocks in the transaction
- instead of binding the block contents to the transaction (read-only checked
out blocks did only see the unchanged blocks until the transaction was closed)
the block now always shows the current data - even if the old way had some
advantages, it was terrible to use
- the blocks were not correctly added to the transaction
- improved debug output
- can check if the read-only blocks were changed accidently (compile time option)

we don't want to copy them over to the kernel heap, we just don't free
the kernel args if the debug symbols are enabled - and since there are
no driver settings yet in the kernel, this is always for now.

Moved from mutexes to benaphores.
Removed partial write support of the old API.
remove_cached_device_blocks() will now actually free all remaining blocks.

to the arch independent section (pure laziness + I am not yet sure how this
will look like on other platforms).
Fixed the clone_area() command: B_CLONE_ADDRESS must not be used in the
same address space, because the area creation then can only fail.
Added an explanation on why the area is cloned at all.

The page_stats debugger command now understands queue names as well.
Some minor cleanup, improved error checking.

Renamed vm_area::lock to vm_area::protection to be less confusing - wiring
is still called wiring, though (might be renamed to lock later, as that's
how BeOS calls it).
Renamed some global variables to match our naming scheme.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9860 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed all static global variables to have the 's' prefix.
acquire_sem_etc() now fails if B_RELATIVE_TIMEOUT and B_ABSOLUTE_TIMEOUT
are both set.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9854 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in snooze_etc(): it could define both, B_ABSOLUTE_TIMEOUT and
B_RELATIVE_TIMEOUT at the same time.

No longer crashes due to architectural VM restrictions (ie. the area
is kernel only but writable now - should be cloned).

and the kernel.
create_area() can now only create kernel areas.
_user_create_area() now directly calls vm_create_anonymous_region().
Removed broken find_region_by_address() and find_region_by_name().
Removed vm_find_region_by_name().
Renamed the idle thread stack areas.

will do this if this function is called by anyone other than the root
user.

for temporary memory anymore, it's the store's responsibility to do that
correctly now, and that functionality is reached via the vm_cache using
vm_cache_set_minimal_commitment().
Therefore, the vm_store commit() function now returns a status instead of
the size that could be commited.
Replaced the max_commit mechanism with one that cares about the available
memory, stores can reserve and unreserve such memory. The anonymous_commit()
will now fail in case it could not reserve the needed amount of memory.

with an empty queue, it crashed. sem_info::latest_holder is obviously not
set correctly, and should be fixed.
Some cosmetics.

in the wrong direction for some time now, corrupting the argument area (user
apps would crash).
B_SYSTEM_TEAM is now reserved, so that no team can be created there.
Fixed some warnings when debug output is enabled.

The inode now keeps track of the number of readers/writers.
Inode::BytesInChain() is now only used protected by the request lock.
Implemented some missing POSIX demands:
- when the last writer is closed, all waiting read requests are aborted
- pipefs_write() now returns EPIPE and signals the current thread with
SIGPIPE in case there are no readers left
- pipefs_read() will now return 0 in case there are no writers and no
unread buffers left in the pipe.

Correctly implemented devfs_create() - it will now open the an already
existing file if O_EXCL is not set, and no longer fail with EROFS.
