1d5026909d Basically reverted previous commit, since at that point we haven't yet
checked the existence of the apics.
Moved the code to disable the local apic from arch_timer.c to arch_int.cpp, so
we also avoid installing the interrupt handler for it.

24ca62447c Only show the "Disable APIC" option if an APIC is found.
Same for the IOAPIC, but commented out the code, since we're not using the
IOAPIC yet.
Also renamed the option to "Disable LOCAL APIC", since it's more correct.

1bcca32a9e * Also take into account that the alignment due to B_ANY_KERNEL_BLOCK_ADDRESS
can cause overflows.
* Added a generic IS_VALID_SPOT() macro that checks for overflows and checks if
  the area will fit with the given constraints.
* Use the macro to simplify the places where these checks are necessary.
* Use the provided "end" limit instead of the address space end. It currently
  doesn't matter but makes more sense.
* Rename newBase variables to alignedBase as that's what they are.

e717a35b6f * Change the way we check for enough available space when searching for spots
to insert areas so we don't overflow.
* Consequently use the area end (base + size - 1) where appropriate which
  prevents overflows in a few places.
* Properly check for reaching the address space end.
* If we've already found a spot we don't need to recheck if we've found one.
* Simplify the B_EXACT_ADDRESS checks down to a simpler single if statement
  instead of the four seperate ones.
* Properly calculate the search end for B_EXACT_ADDRESS as well, it's also
  base + size - 1.
* Block the full last page now that this actually works without overflowing.
* Some style changes and added spacing.

This should now really fix #2550. Previously the overflow protection didn't
actually work because on allocation we overflowed and completely missed the
protecting area.

65b5e4d7ed Make use of the address range blocking to guarantee that accessing 0xdeadbeef
and 0xcccccccc (and 64 pages thereafter) in any way will always lead to a crash.
Before it could happen that these ranges were allocated for an area and then
accessing these would not be as evident anymore. Only enabled when the
corresponding paranoid setting is enabled (which it currently is).

9aff7f1593 Block the very last page of kernel address space. The problem here is that non
of the VM functions handling areas are overflow safe. If an area is created that
spans across the last page many places will run into an integer overflow. This
mostly concerns the area allocation path in find_and_insert_area_slot() and also
vm_create_anonymous_area() where the loop for mapping pages for B_FULL_LOCK
areas overflows and runs more times than it should leading to #2550.
This could be seen as a workaround. The real fix would be to make everything
overflow safe. The thing is that this does also concern the user of the area
which could easily have forgotten to check for overflows as well, so I am a bit
uneasy with handing out areas that could easily lead to such hard to debug
problems. Since this is really an edge case and this single step safes quite a
bit of extra checks I'd actually be OK with keeping it that way.

257f000bd2 * When reserving pages and there aren't yet enough free pages, only steal as
many pages as are actually missing, not the full count.
* Take into account that free_page_queue_count() can be less than sReservedPages
  (when some of the reserved pages have been allocated already) in
  vm_page_num_unused_pages(). Before it could return negative and therefore
  wrapped numbers.
* Simplify the page scrubber loop by continuing early. Also avoids a needless
  interrupt spin lock acquisition when there's nothing to do.
* Some minor coding style cleanup.
* Fix a typo.

185fd1c5d2 Ported over the kernel heap to libroot to make use of it's validation
capabilities to aid in debugging memory corruption issues.

It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees

It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.

419f2d6f3e Fix errors in maintaining the area list due to assumptions that are only true
for the page list but not the area one. Since multiple pages can be allocated
at once, even an area that is not at the top of the list can become empty. In
such a case the area list would previously have lost entries. Also because
we can remove more than one page from any area, not just the top one, we may
need to move forward in the list so that it stays ordered by free pages.

92e143c14a Fix regression introduced in r32526: registering the device watcher for node monitoring needs to happen synchronously, otherwise a race condition occurs: unless you're very lucky, the event for creating the raw device would happen before the async thread had a change to add the node monitor, and as such the listener would miss it, and never trigger a filesystem/partition scan. As a result, whether or not adding a USB stick would actually show a volume was essentially russian roulette. Fixes ticket #4345.
