Revert r36886 and fix compilation of insert_virtual_range_to_keep().
The use of void* vs. addr_t matches the surrounding boot loader code
but should probably be revised in favour of addr_t.
create_area() in the kernel wrongly assumed a RAM-backed address range,
which was destined to fail since ranges below the kernel address space
were ignored anyway. Use vm_map_physical_memory() instead.
This fixes a hang once the frame buffer and other resources used by OF
get unmapped. Closes ticket #5193 again.

turned out it's pretty much broken. Not only did it potentially leak memory,
it would also potentially replace the original data with a NULL pointer,
making the current transaction non revertable. The code should now be much
clearer. This fixes bug #6378.
* Changed a few "if (... != NULL)" into ASSERTs, since the code should bail out
earlier in these cases already.
* Added a TODO comment to cache_start_sub_transaction() about its broken discard
handling. This can cause FS corruptions in case the parent transaction is ever
going to be aborted (which shouldn't happen in real life, though).
* Added a bit more and better comments.

* adjusted the syscalls get_timezone() & set_timezone() as well as their callers
accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
being referred to by the FAT add-on and that one (like gettimeofday()) put a
different meaning to tz_minuteswest. Added a comment to FAT's util.c
showing a possible solution, should the hardcoded GMT timezone pose a problem.

the RTC info

interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.

* PageWriterRun::Go(): Returns the number of pages that could not be written.
* page_writer()/next_modified_page():
- Don't use a marker page anymore. A visited page is requeued at the tail.
This also makes the functions that schedule pages work a bit better (they
queue the pages at the head of the queue).
- Have an eye on pages that are busy or failed to write. If we ran through
the whole modified queue without writing a single page, sleep for a short
time. This mitigates the busyness the page writer falls into when there
are enough modified pages to make it run all the time but none that can be
written successfully.

incrementing the cache color cycle. Using the fixed value (8) would
potentially misalign the object again.
* Don't use CACHE_ALIGN_ON_SIZE for object caches any longer -- we have the
alignment parameter anyway (the flag is still used for the MemoryManager,
though).
* ObjectCache::InitSlab(): Slab coloring *was* done when CACHE_ALIGN_ON_SIZE
was given, i.e. exactly the wrong way around. Also the cache_color_cycle
computation was weird -- color 0 was used twice in a row.

vm_page::Init().
* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
used to request a special handling for wired pages. If given the wired pages
are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
- We don't need to do any wired ranges handling, if the source area is a
B_SHARED_AREA, since we don't touch the area's mappings in this case.
- We no longer wait for wired ranges of the concerned areas to disappear.
Instead we use the new vm_copy_on_write_area() feature and just let it
copy the wired pages. This fixes#6288, an issue introduced with the use
of user mutexes in libroot: When executing multiple concurrent fork()s all
but the first one would wait on the fork mutex, which (being a user mutex)
would wire a page that the vm_copy_area() of the first fork() would wait
for.

continues to work fine when the physical memory > 4 GB is used. Otherwise it
hangs or crashes.

restrictions for virtual/physical addresses.
* vm_page_allocate_page_run():
- Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
taken into account.
- Takes a physical_address_restrictions instead of base/limit and also
supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
{virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
- Fixed potential overflows of uint32 when initializing from device node
attributes.
- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

which caused the upper 32 bit of the address to be ignored, thus mapping to
the wrong page.

since the flags are in the lower 32 bits anyway.

Kernel doesn't use it, and it could be regenerated in the kernel if it did need it.
This also unlocks the apic range the bios can use. Previously the apic ids would have
to fit within 0..MAX_CPUS or it'd reject the cpu. Some boxes (mine in particular)
seem to sparsely populate the apic id so that the range is pretty large.

* Extended call_all_cpus[_sync]() to work before smp_wake_up_non_boot_cpus()
(even before smp_init()).

still need to be implemented, though.

page with a 32 bit physical address (needed for the PDPTs). A small set of
free pages is cached, so the rather expensive vm_page_allocate_page_run() can
be avoided most of the time.

* The 32 bit paging structures inherited from the boot loader are translated
to PAE structures and PAE is enabled.
* Implemented the initialization of the initial PhysicalPageSlotPool, so that
the physical page mapper can be initialized.

* Made all helper function operating on paging structures static methods of
X86PagingMethod32Bit.

accessed from anywhere. Added static X86PagingMethod32Bit::Method()
returning it as the subtype pointer -- to be used in the code related to
that method only, of course.
* Made a bunch of static variables non-static members of
X86PagingMethod32Bit and added accessors for them. This makes them
accessible in other source files (allowing for more refactoring) and saves
memory, when we actually have another paging method implementation.

* Renamed X86VMTranslationMap to X86VMTranslationMap32Bit and pulled the paging
method agnostic part into new base class X86VMTranslationMap.
* Moved X86PagingStructures into its own header/source pair.
* Moved pgdir_virt from X86PagingStructures to X86PagingStructures32Bit where
it is actually used.

agnostic:
* Changed return value of X86PhysicalPageMapper::[Interrupt]GetPageTableAt()
from page_table_entry* to void*.
* Made PhysicalPageSlotPool an abstract base class. The paging method provides
an implementation and creates the pools now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37054 a95241bf-73f2-0310-859d-f6bbb57e9c96
Introduced the interface X86PagingMethod which is used by those. ATM
there's one implementing class, X86PagingMethod32Bit.
* Made X86PagingStructures a base class, with one derived class,
X86PagingStructures32Bit.

overridden.

* Renamed i386_context_switch() to x86_context_switch().
* x86_context_switch() no longer sets the page directory.
arch_thread_context_switch() does that explicitly, now. This allows to solve
the TODO by reordering releasing the previous paging structures reference and
setting the new page directory.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37024 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renamed vm_translation_map_arch_info to X86PagingStructures, and all
members and local variables of that type accordingly.
* arch_thread_context_switch(): Added TODO: The still active paging structures
can indeed be deleted before we stop using them.

* DMABuffer, IORequest, IOScheduler,... and code using them: Use
generic_io_vec and generic_{addr,size}_t where necessary.

of having the logic be triggered by IOScheduler::SetDeviceCapacity(), as that
one might actually be called more often (for each call to update_capacity(),
ie. each B_GET_GEOMETRY/B_GET_DEVICE_SIZE will trigger it), and there is no
reason to throw away the cache every time (will make a difference during
partition/file system detection).
* In cd_init_device() just call update_capacity() instead of duplicating its
code.

map_physical_memory()'s physicalAddress parameter type from void* to
phys_addr_t. This breaks source compatibility, but -- as long as
phys_{addr,size}_t remain 32 bit wide -- keeps binary compatibility with
BeOS.
* Adjusted all code using the affected interfaces (Oh what fun!). Added a few
TODOs in places where the wrong types (e.g. void* for physical addresses
are used). Looks like quite a few drivers aren't 64 bit safe and others
will break with PAE.

vm_page.{h,cpp}.

map_backing_store() doesn't commit memory when this flag is given.
* Used the new flag vm_copy_area(): We no longer commit memory for read-only
areas. This prevents read-only mapped files from suddenly requiring memory
after fork(). Might improve the situation on machines with very little RAM
a bit.
We should probably mark writable copies over-committing, since the usual
case is fork() + exec() where the child normally doesn't need more than a
few pages until calling exec(). That would significantly reduce the memory
requirement for jamming the Haiku tree.
