72156a402f bonefish+mmlr:
* Introduce "paranoid" malloc/free into the slab allocator (initializing
  allocated memory to 0xcc and setting freed memory to 0xdeadbeef).
* Allow for optional stack traces for slab object cache tracing.

fc2d7cb04d * Introduce {reserve|allocate|free}_io_interrupt_vectors() that can generically
be used to mark certain io interrupt vectors as reserved and to allocate from
  the still free ones. It is a kernel private API for now though.
* Make the MSI code use that functionality instead of implementing its own which
  slims it down considerably and also removes quite a bit of hardcoded knowledge
  about the interrupt layout that didn't really belong there.
* Mark the various in-use interrupts as reserved from the components that
  actually know about them (PIC, IO-APIC, SMP, APIC timer and interrupt setup).

d230708bcf * Expand kernel_args addresses ranges size, 8 is somewhat too small, leading
to a panic at boot.
* Make the panic message more explicit when there is no more room left.

d24ddec4e4 * Move platform support.cpp into less generic of_support.cpp
* Add header file to support of_support.cpp
* Add support functions to obtain address and size cell lengths
* Small style cleanups
* Add support for G5 PowerPC cpus...
* Refactor memory region code to be aware of 64-bit OF addresses.
  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.
  Thanks for the idea DeadYak!

285f4cf441 * Added optional partition_module_info::uninitialize() hook. It is supposed to
destroy the partitioning system's on-disk structure.
* Adjusted the existing partitioning system implementations accordingly.
  Actually implemented the hook for the intel partitioning system.
* Added Uninitialize() method to KDiskSystem and KPartitioningSystem. The latter
  implements the method calling the new module hook.
* _user_uninitialize_partition(): Also let the disk system uninitialize the
  on-disk structure.

This fixes the failure to initialize a disk device with BFS, when it contains a
valid partition map with at least one partition.

  loader menu. It displays what the boot loader has logged so far. Might be
  interesting for early boot issues when serial debugging is not possible.

73df2f2086 * Add validation of the RSDP checksums.
* If we detect ACPI 2.0 or higher, the spec says we should use the XSDT rather
  than the RSDT. Attempt to do so, falling back to the RSDT if the former fails
  to be mapped/validated.
* Refactored acpi_find_table into a templated version to account for the fact
  that the XSDT exports different pointer widths for its links to other tables
  than the RSDT.

8bcc50c336 * Added arch_debug_blue_screen_try_getchar() and arch_debug_serial_try_getchar()
which don't wait for a character, but return -1 when no character is
  available ATM. Implemented correctly for x86 only.
* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
  It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
  achieve that. It does now start, check, or cancel a transfer. Split
  UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
  CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
  The latter seems to have issues. Michael, please have a look. I have no clue
  what I'm doing. :-)
* Adjusted kgetc() to poll all possible inputs using the new
  functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
  handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
  support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
  of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
  [set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.

* Reimplemented gdb_regreply() to use that. Also made it buffer overflow safe.

8837310ce7 * Slightly alter the semantics of the input gathering function to take the
menu item it's associated with rather than an input string. This allows it
  to calculate the position to start the input at, as well as the correct
  line to place it on. The previous solution always put the input at the
  center line, which happened to be the right place by happy coincidence
  unless one also had the menu items for viewing/saving the debug syslog
  present.
* Implement input buffer scrolling, and consequently lift the previous size
  limit on user input (it is now only limited by the size of the passed in
  buffer).
* Implement parsing of the input buffer to allow it to handle comma-separated
  options. Thus, one can now input things like "disable_smp true, serial_debug_output false"
  and it will be handled properly.

d2b49a0031 * Implement support for user input of additional safe mode options that
aren't otherwise exposed via the safe mode menus. The option can be 
found under the debug options menu, where additional settings can be 
added one at a time with the same syntax used in kernel settings files 
(i.e. disable_acpi on). 

Scrolling of the input buffer is not yet supported (will implement that 
soon), so currently the input is clamped to the size of one line. This 
shouldn't be a problem for our current set of options though.

fb5a1727f4 * Implement interrupt source overrides. We install a relay interrupt handler
at the override entry to trigger the overriden vector so that we don't need
  to configure any additional redirections.
* Also configures the polarity and trigger modes found in the override entry.
* When disabling the legacy PIC, retrieve the enabled interrupts and re-enable
  then in the IO-APIC. This will for example make the ACPI SCI work that is
  installed prior to switching interrupt models. Through the transparent support
  for interrupt source overrides it'll also automatically relay from the old to
  the new vector.

This should make ACPI interrupts work and should support relocating the ISA PIT
from irq 0 to a different global system interrupt (usually 2) so that it can
still work when IO-APICs are in use.

8908aef9c2 * Don't map the IO-APIC within the bootloader. We don't need it to set up SMP
at all and, since there can be multiple IO-APICs, we need to do the
  enumeration again in the kernel anyway. Also only set ioapic_phys the first
  time we encounter an IO-APIC object as it looks cleaner when we arrive at the
  first IO-APIC default address.
* Therefore we don't have to worry about already mapped IO-APICs when
  enumerating them in the kernel.
* Also remove the mapping function that is now not used anymore.
* We still use the ioapic_phys field of the kernel args to determine whether
  there is an IO-APIC at all to avoid needlessly doing the enumeration again.

This fixes multi IO-APIC configurations, because before we would indeed map
the last IO-APIC listed in the MADT, but then in the kernel assumed we mapped
the first one. We'd end up with mapping the last listed IO-APIC twice and the
first IO-APIC never, always programming the last one when we actually targetted
the first one.

a56cbb2afb * When initializing MSI support, don't assume a single 24 entry IO-APIC. Instead
mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
  to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
  not used, this will simply always return false, leaving all vectors free for
  MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
  done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
  we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
  routing anymore).

d2bf328d72 Implemented a generic system watching mechanism with a userland API. Currently
only a few events can be watched (team creation/deletion/exec, thread creation/
deletion/name changes). The functions start_system_watching()/
stop_system_watching start/stop watching events.

2d8d1cdbaa * Implemented a generic way to associate data with a team which is
automatically cleaned up when the team is deleted: Class AssociatedData is
  the base class for a data item, AssociatedDataOwner a container for them
  (struct team derives from it). Functions team_associate_data() and
  team_dissociate_data() add/remove data.
* Turned sTeamHash into a BOpenHashTable (necessary since struct team is no
  longer a POD).

use C++.
