3684e40bb8 * Introduce a (private) flag B_NO_HANDLED_INFO for install_io_interrupt_handler.
It causes the interrupt handler to be inserted at the very end of the list
  instead of at the top. It is intended to be used as a workaround when a
  interrupt handler cannot know if it actually handled the interrupt. This
  should never be used by native drivers. Also if we know that the result is
  not valid because of this flag we won't disable the vector in case we count
  many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
  instead of the doubly linked one used with insque and remque as it greatly
  simplifies things for such an easy use case and is more compact.

d9c6f9a92c Remove separate GCC4 versions of add_debug_command()/remove_debug_command() and
add the const in any case. As Axel points out these are C functions and we do
not affect binary compatibility by changing their signature.

c33667d400 Fixing warnings under GCC4 in preparation to enable -Werror there as well:
* Replaced the use of offsetof() for structs that aren't PODs. Add a
  offset_of_member() macro to util/khash.h because that's what it's used for
  in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
  GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
  it pointed out at least one bug that is fixed here as well.

6e60a6ac03 Added function get_memory_map_etc() which works similar to
get_memory_map(), but has a saner semantics and allows specifying a
team.

736352dcf5 * Added [un]lock_memory_etc() versions that accept a team_id as first argument.
This allows drivers to lock the memory outside of the original team context.
* create_area_etc() got a struct team as first argument, but that should have
  been a team_id.
* Removed delete_area_etc() - there is already vm_delete_area() doing the same
  thing.
* Renamed vm_get_address_space_by_id() to vm_get_address_space(), as there is
  no other method of getting an address space.
* Removed erroneous white space.

1c8de8581b * Added optional spinlock contention measurement feature. Enabled when
B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
  structure (thus breaking BeOS binary compatibility), containing a
  counter which is incremented whenever a thread has to wait for the
  spinlock.
* Added macros for spinlock initialization and access and changed
  code using spinlocks accordingly. This breaks compilation for BeOS --
  the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
  the team spinlocks.

037f70947f * Cleaned up KernelExport.h completely, removed deprecated and non implemented
API, uses the _PRINTFLIKE macro where appropriate.
* Got rid of the "qent" structure, struct timer now contains everything we
  need. This makes the affected code in sem.cpp, signal.cpp, and timer.c much
  cleaner, and resolves a few TODOs.
* Minor cleanup in vfs.cpp.

f87d72d788 Introduce a B_NO_LOCK_VECTOR flag to be used with install_io_interrupt_handler().
When specified it desigantes that the interrupt handler should not lock the
vector with a spinlock when executing the installed interrupt handlers. This
is necessary to allow the same interrupt vector to be handled in parallel on
different CPUs. And it is required for the CPU halt to work synchronously when
there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs
to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me.
Not locking is safe as long as it is guaranteed that no interrupt handler is
registered or removed while the interrupt handler is running. We can guarantee
this for the SMP interrupt handlers we install in arch_smp_init() as they are
never uninstalled. Probably this flag should be made private though.
Restored the SMP_MSG_FLAG_SYNC when entering the kernel debugger.

badc7b674e yet another fix for #1018, which has at this point blossomed into a reorg of how AP cpus are initialized.
the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the 
current thread, but that has a race condition that would require an int disable, etc.

d4112f6bc5 Applied some changes suggested by mmu_man, more to come, though:
- has_signals_pending() is not declared in Be headers, and it isn't declared in
  our KernelExport.h anymore, too
- removed snooze_etc() from KernelExport.h, as it's already defined in OS.h
  (and really exported by libroot.so).

b20667b35b {install|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag.
Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
  described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
  it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
  is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
  (though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
  "status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
  equivalent (and private) are_interrupts_enabled()
