* Fix build broken in r43078. The slab_debug_add_allocation_for_caller()
wasn't guarded correctly.
* slab_debug_add_allocation_for_caller(): Add bool resetAllocationInfos
parameter, which makes the function clear the allocation tracking
infos after processing the data.
* "allocations_per_caller" KDL command: Add option "-r" to reset the
allocation tracking infos. The next invocation of the command will
only show the allocations made after the reset.

size from the caller infos instead of using return arguments in the

function slab_debug_add_allocation_for_caller(), so it can be reused.
* Add MemoryManager::AnalyzeAllocationCallers() to collect the

* Add optional stack trace capturing for slab memory manager tracing.
* Add allocation tracking for the slab allocator (enabled via
SLAB_ALLOCATION_TRACKING). The allocation tracking requires tracing
with stack traces to be enabled for object caches and/or the memory
manager.
- Add class AllocationTrackingInfo that associates an allocation with
its respective tracing entry. The structure is added to the end of
an allocation done by the memory manager. For the object caches
there's a separate array for each slab.
- Add code range markers to the slab code, so that the first caller
into the slab code can be retrieved from the stack traces.
- Add KDL command "allocations_per_caller" that lists all allocations
summarized by caller.
* Move debug definitions from slab_private.h to slab_debug.h.

* Add tracing_find_caller_in_stack_trace(). Helper function to get the
first return address of a stack trace that is not in one of the given
address ranges.

* Add tracing_is_entry_valid(). Checks, based on the additionally given
time, whether a tracing entry is (probably) still in the tracing
buffer.

* 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.

from other CPUs might see debug_debugger_running() == true already before they
enter the debugger.
* Instead, move the sDebuggerOnCPU setting out of the debugger loop and hold the
value until after calling exit_kernel_debugger() so that the exit hooks still
see debug_debugger_running() == true.
* Also avoid calling exit_kernel_debugger() when we've been called recursively
(previousCPU != -1). Previously the exit hooks would've been called and the
debugger state reset erroneously. To balance the missing decrement of
sInDebugger in that case we decrement sInDebugger in enter_kernel_debugger()
also when detecting the recursion case.

This fixes the issue Ingo saw where the USB physical memory manager wasn't able

it uses depending on debug_debugger_running() and was therefore confused when
it returned false when called from the kernel debugger module exit hook.

the acquired quota in sTotalSpaceInUse wasn't released in all cases leading to
it eventually reaching the limit (after a _very_ long time though, so this is
more theoretical than anything else). The sAllocatingArea flag wasn't reset in
the case that an area was already added in the meantime, resulting in no
further growing being possible. Then there were race conditions between
waiting for space to become available and the situations which made that space
available (freeing port_messages and adding new areas).
* Fix these race conditions by using a mutex (sPortQuotaLock) to protect the
various quota and allocation related variables. Instead removed the atomic_*
operations that were previously used.
* Had to move some static functions around.
Should make port heap growing more robust, even though in normal use you'll
likely never encounter it...

Since we don't currently support the XSDT, we can't rely on that field and have to resort to the previous approach of mapping the RSDT header in order to determine the length of the RSDT itself.

check if all of them are assigned with a routing entry. If not, as happens for
PCI add-on cards that ACPI isn't aware of for example, infer the routing by
calculating it from the PCI default routing and going up through the parents
until a matching routing entry is found. Fixes#7520.
* This will also panic (for now) in case there remain unroutable devices and
eventually will prevent the IO-APIC to be used in these cases.
* Enabled some debug output.

cases such as USB keyboards where the keyboard no longer functions once the
kernel is entered and the USB stack initializes.
Implements #7561.

actually be a bridge. We always want to check if the device at hand is a PCI
bridge, because in that case we need to recurse further down. We recurse now
even if there is no routing table found for the current bridge, since that
doesn't mean that another bridge, further below, can't have a routing table
again. Possibly fixes#7520.
* Fix the matching function to just check for function 0 to be present instead
of classifying it. Previously if there happened to be a cardbus bridge on
function 0 of a multi function device, the rest of the functions of the device
would've been ignored because we returned early due to the unsupported bridge.
* Only hand down the current bus number when recursing as that makes it clearer
what's going on instead of handing in a partially filled out pci_address
structure and then filling in other parts inside the function.
* Commented out getting the segment number as we don't support it at all.
* Extended debug output.

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.
