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.

This also unlocks the apic range the bios can use. Previously the apic ids would have

* 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.

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.

easier to review as individual patches against trunk, versus as a new version
of the huge patch.
I've messed a lot with src/servers/notification/NotificationsView.cpp in order
to resolve a crash I was getting when testing this thing (rewrote line
wrapping). I've also replaced the icons with the one that zuMi did long ago.

* Changed the type of the kernel_args physical address range arrays to
phys_addr_range and adjusted the code working with those.
* Removed a bunch of duplicated address range code in the PPC's mmu.cpp.

vm_page.{h,cpp}.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36937 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.
Might break the build under older Haiku installations. Will test next.

A note to those using "update-all" with hybrid builds - the alternative GCC
system libs will not be updated this way, and this and Wim's last patch

not start anymore.

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.

debug_init_post_settings().

there really is a show stopper in the init process, panicking would be the
thing one should do.

* Moved the B_OVERCOMMITTING_AREA flag from B_KERNEL_AREA_FLAGS to
B_USER_AREA_FLAGS, since we really allow it to be passed from userland.
* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
instead of B_USER_PROTECTION, now. This way they allow for
B_OVERCOMMITTING_AREA as well.
* _user_map_file(), _user_set_memory_protection(): Check the protection like
the other syscalls do and use fix_protection() instead of doing that
manually.

boot CPU wait until all other CPUs are ready to wait. This solves a
theoretical problem in main(): The boot CPU could run fully through the early
initialization and reset sCpuRendezvous2 before the other CPUs left
smp_cpu_rendezvous(). It's very unlikely on real hardware that the non-boot
CPUs are so much slower, but it might be a concern in emulation.

* Changed the WriteCMAP() color conversion function to expext a 32bit RGBA
value and use IndexForRGBA32().
* Adapted B_CMAP8 target color space case of ConvertBits() to the new
semantics.
This allows transparency in bitmaps when converting B_RGBA32 bitmaps to
B_CMAP8, tested only for this case and working as expected.

free respective free and cached pages.
* Removed the unused vm_page_allocate_page_run_no_base().
* vm_page_allocate_page_run() (and allocate_page_run()):
- Use vm_page_reserve_pages() instead of vm_page_try_reserve_pages(), i.e.
wait until the reservation succeeds.
- Now we iterates two times through the pages to find a suitable page run. In
the first iteration it only looks for free/clear pages, in the second
iteration it also considers cached pages. This increases the chance of the
function to succeed, when a lot of caching is going on.
This reduces the amount of memory required to use the IOCache when booting
off the anyboot Live CD to around 160 MB in qemu. It also seems to work with
128 MB, but the syslog indicates that some memory allocations fail, which
is not exactly inspiring confidence.

- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.

* debug_{mem,strl}cpy():
- Added "team" parameter for specifying the address space the address are
to be interpreted in.
- When the standard memcpy() (with fault handler) fails, fall back to
vm_debug_copy_page_memory().
* Added debug_is_debugged_team(): Predicate returning true, if the supplied
team_id refers to the same team debug_get_debugged_thread() belongs to.
* Added DebuggedThreadSetter class for scope-based debug_set_debugged_thread().
Made use of it in several debugger functions.
* print_demangled_call() (x86): Fixed unsafe memory access.
Allows KDL stack traces to work correctly again, even if the page daemon has
already unmapped the concerned pages.

* Add the remaining IDT entries and redirection functions in the interrupt code.
* Make the PIC end_of_interrupt() return a result to indicate whether the vector
was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt()
in the assumption of apic local interrupt, MSI or IPI. This also removes
the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt()
calls in the SMP and timer code.

locks.
* Added syscalls for a new kind of mutex. A mutex consists only of an int32 and
doesn't require any kernel resources. So it's initialization cannot fail
(it consists only of setting the mutex value to 0). An uncontended lock or
unlock operation can basically consist of an atomic_*() in userland. The
syscalls (when the mutex is contended) are a bit more expensive than semaphore
operations, though.

* Added new thread flag THREAD_FLAGS_ALWAYS_RESTART_SYSCALL. If set, it forces
syscall restart even when a signal handler without SA_RESTART was invoked.
* Fixed sigwait(): If one of requested signals wasn't already pending it would
never wake up. Also, the syscall always needs to be restarted, if interrupted
by another signal.
* Renamed a bunch of the POSIX signal function implementations which did return
an error code directly (instead via errno). Added correct POSIX functions
where needed.

* lock_memory_etc(): On error the VMAreaWiredRange object could be leaked.
* [un]lock_memory_etc(): Call VMArea::Unwire() with the cache locked and
explicitly delete the range object after unlocking the cache to avoid
potential deadlocks.

Since the requirement is that the area's top cache is locked, allocating
memory isn't allowed.

locking the area's top cache.
Fixes#5680 (deadlocks when using the slab as malloc() backend).

* _user_map_file(), _user_unmap_memory(): Verify that the address (if given) is
page aligned.
* Reworked memory locking (wiring):
- VMArea does now have a list of wired memory ranges and supports waiting for
a range to be removed.
- vm_soft_fault():
- Added "wirePage" parameter that, if given, makes the function wire the
page and return it.
- Added "wiredRange" parameter (for calls from lock_memory_etc()) and made
sure we never unmap wired pages. This could e.g. happen when a page from a
lower cache was read-mapped and a write fault occurred. Now in such a
situation the function waits for the page to be unwired and restarts.
- All functions that manipulate areas in a way that could affect wired ranges
do now either require the caller to make sure there are no wired ranges in
the way or do that themselves. Added a few wait_if_*_is_wired() helper
functions for that purpose.
- lock_memory_etc():
- Does now also work correctly when the range spans more than one area.
- Adds VMAreaWiredRanges to the affected VMAreas and retains an address
space reference (so that the address space won't be deleted as long as a
wired range exists).
- Resolved TODO: The area's caches are now locked when
increment_page_wired_count() is called.
- Resolved TODO: The race condition due to missing locking after looking up
the page mapping is now prevented. We hold the cache locks (in case the
page is already mapped) and the new vm_soft_fault() parameter allows us
to get the page wired.
- unlock_memory_etc(): Changes symmetrical to those in lock_memory_etc() and
resolved all TODOs.
