It's a bit hackish due to the iospace area, and it also might not work
perfectly in all situations, but it does fulfill the current needs.

cache_node_{opened|closed}() now correctly get the file_cache_ref from a vm_cache_ref.
Implemented cache_prefetch(): for now, it always prefetches the first 64 kB from the file.
Renamed read_from_cache() to read_into_cache().

different types to vnodes.
Renamed vfs_get_vnode() to vfs_lookup_vnode() as it doesn't grab a ref to the node.
Added new vfs_get_vnode() that actually grabs such a ref.
vfs_get_vnode_cache() now fills a vm_cache_ref instead of a void pointer.
Replaced SYS_MAX_NAME_LEN constants with the B_FILE_NAME_LENGTH that should have
been used there.
vnode::cache should have been a vm_cache_ref and is now.

Later on (but before R1), we should find a better balance between what
the FS has to implement, and what the kernel delivers to them.

Also fixed a minor bug in dec_vnode_ref_count(): the unusued vnode counter
was not decremented again when one vnode was removed.

actually fills a cpuid_info structure. Renamed cpuid() to get_current_cpuid().
Added syscall _user_get_cpuid().
Added a lot of other vendor brand strings. The cpu_type and cpu_revision
fields should now be correctly set.
get_cpuid() now returns B_BAD_VALUE if the cpuNum parameter is out of bounds
(ie. higher than the number of available CPUs in the system).

team_init() now returns a status_t.
System info stuff is now globally initialized in main().
get_system_info() now also reports the number of used pages, and calls the
architecture dependent function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10315 a95241bf-73f2-0310-859d-f6bbb57e9c96

When the 0xe820 memory map method doesn't work for whatever reason (broken BIOS),

it does so.

the FS release/remove vnode calls. Extended comments.
Added "flags" parameter to unmount.

(free_vnode()). Upon freeing, the file cache is now only written back if the
file is not deleted.
dec_vnode_ref_count() no longer frees vnodes that are not going to be deleted.
Instead, it will add them to an unused vnode list, so that they can be freed
if needed (currently only 512 unused vnodes will be kept around). This should
speed up the whole thing, and makes the file cache much more useful, as it's
no longer dumped after the file is closed.
fs_unmount() is not yet respecting this (ie. it doesn't free those nodes as
it should).

Renamed _user_set_tzspecs() to _user_set_timezone().
Renamed sTzFilename to sTimezoneFilename.
Moved rtc_print() into rtc_debug().
Fixed changing system_time_offset; since this is a shared 64 bit value,
we have to use atomic calls when we change it.

For now, it always returns B_ENTRY_NOT_FOUND - since the boot loader
does not have support for driver settings yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10237 a95241bf-73f2-0310-859d-f6bbb57e9c96

booting into Haiku.

dirty pages of this cache back to disk (using the new vm_page_write_modified()

While we can tolerate the device driver to ignore the bytes argument when we
read from the device, we cannot do this for writes - now the code actually
takes this into account. Also added a comment about what to do when our own
driver is fixed :)
Implemented file_cache_sync().
file_cache_set_size() now uses vm_cache::virtual_size instead of the now
removed vnode_store::size. Also, it now resizes the vm_cache as well, so
that any no longer used pages are freed.
write_to_cache() now puts all pages in the modified list, so that they
can be written back easily.
Improved debug output.

dec_vnode_ref_count() now deletes the cache *after* calling the file system's

As a quick hack, they no longer disable interrupts, so that the env memory

Fixed a bug in the team thread start: it did not set sizeLeft correctly
before copying the arguments - shouldn't have had any consequences, though,
as the size of the arguments is known before.
Added a comment explaining the current layout of the main thread stack area.

Fixed a bug in arch_init_tls() that did not support different stack sizes
(ie. didn't use the thread::user_stack_size variable).

B_BAD_HANDLER, vm_soft_fault() will just continue as if there is no fault()
function.
There is now support for the B_STACK_AREA and B_KERNEL_STACK_AREA protection
values: if the former is used, or the latter in combination with DEBUG_KERNEL_STACKS,
a number of guard pages is inserted at the bottom of the stack (depending on
the STACK_GROWS_DOWNWARDS/UPWARDS arch config).
In addition, user stacks are no longer committed completely, ie. they don't
reserve memory for their whole size, only as much as is needed. That may
result in applications crashing when they need a lot of stack and there is
no memory left. Before this change, you could not even run that application.
Since BeOS has a 16 MB stack for the main thread, you could only run about
2 applications with 64 MB before.
Due to these changes, we've now switched to the standard BeOS stack sizes.
Some minor cleanup.

- renamed setup_rtc_boottime() to __init_time()
- __init_time() is now initialized at libroot.so startup
- introduced new __arch_init_time() that does the arch dependent stuff,
for now it just sets the system_time() conversion factor (that's the
part that will change later on)
- os/time.c now keeps a pointer to the real_time_data around, not only
to the boot time - maybe we'll it for other stuff as well later.

- 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
