* add implementations for the following multibyte-related
functions:
btwoc()
mblen()
mbrlen()
mbrtowc()
mbsinit()
mbtowc()
wcrtomb()
wcswidth()
wctob()
wctomb()
* the implementation of the above function live in a symbol
named __<name>, the above symbol names are defined as a weak
alias to the internal ones - TODO: we need to make sure to
only invoked the internal functions (i.e. prepended with __)
in order to avoid problems with symbol preemption.
* deactivate the limited mb implementation we provided before,
as well as respective stuff from glibc
* add actual converter methods MultibyteToWchar() and WcharToMultibyte()
to locale backend and implement them in the ctype subpart
* add management code for maintaining converters referenced by mbstate_t
Validate the candidate child device a bit more by checking the device ID
and the base and subclass of the device. We don't even know if the child
is still on the PCI bus and some firmware may mark disabled devices by
simply invalidating one of these values. Possibly fixes#8111.
Added TODO concerning that we might not want to fail at all since we
ensure that we matched all devices after routing preparation at which
state we would notice any missing child devices anyway.
While the log of hrev35726 says that unusable page ranges are supposed
to be marked with PAGE_STATE_UNUSED and allocated ones with
PAGE_STATE_WIRED, both actually marked with PAGE_STATE_UNUSED.
When limiting the available memory by reducing the page count it may not
be enough to just limit sNumPages. Depending on the physical memory map
non existing pages between ranges (sNonExistingPages) would still be
added up and later subtracted from the sNumPages, resulting in a wrong
max page count. Also due to the fixed removal of non existing page
ranges the actually available memory would usually not be the amount
set via LIMIT_AVAILABLE_MEMORY.
Instead we now calculate the available memory when going through the
physical memory ranges and limit/exit as soon as we've reached the
desired amount of available memory (also ignoring further non-existing
pages).
* Ensure that we don't underflow the used_pages count and that used
+ cached pages don't overflow max_pages. As there is no locking the
values may change while we read them so that such situations could
arise.
* Make the TODO about the missing locking into a Note explaining the
above, as it is not really worth adding locking here. The stats are
only informational.
CFE is used in the upcoming Amiga X-1000 dualcore PPC board.
* Largely inspired by the OF and U-Boot code.
* Still largely stubbed out.
* The loader builds but I don't have a machine to test it. Anyone interested?
* The altered used pages calculation of hrev43168 wasn't correct, as
the inactive page queue may (validly) contain mapped pages as well.
Those would then get counted twice (as they are included in
gMappedPagesCount already).
Instead we calculate the used pages from the total page count, minus
everything we account for otherwise. Doing it this way is possible
without introducing any additional counters, as all the counts to
subtract are already present (as opposed to some of the ones that
would be needed for adding the counts up). Fixes#8109.
* Added TODO regarding the problem of not locking any of the counters
which runs the risk of them getting modified while we haven't yet read
all of them.
* Subclass ConsoleNode as VTConsole
* use it to implement SerialConsole
* Use it as the default console for now to simplify debugging.
VTConsole could probably be factored out into boot/platform/generic/ someday.
* Also reset the local and IO APIC base physical addresses when configuration
failed.
Should fix#8102, but is otherwise untested for lack of old enough hardware.

They were too small for all the fields added. This is why the system
profiler skipped "thread added" notifications.

get_iframe_registers() in arch_user_debugger.cpp return the correct
eax/edx values also when the kernel was entered via an exception that
doesn't push an error code (e.g. page fault).
Fixes incorrect eax and edx values shown in Debugger and variable values
based on them.

of the slab code. It is generic as it only contains the link to a tracing entry
and not any application specific info.

Wastes a bit less time allocating pages for nothing, and makes debugging
mmu support less verbose as well.
The (gunzipped) tar file is still less than 4MB and will never be 8MB
realistically anyway.

* Turn VMCache::consumers C list into a DoublyLinkedList.
* Use object caches for the different VMCache types and the VMCacheRefs.
The purpose is to reduce slab area fragmentation.
* Requires the introduction of a pure virtual VMCache::DeleteObject()
method, implemented in the derived classes.

* Add "allocation_infos" KDL command. Can be used to print the allocation info,
including the stack trace, given an object cache, slab, allocation within a
slab or allocation address. It can also optionally be filtered by team/thread.
* Fix the AllocationDetailPrinterCallback to not access a possibly invalid
trace entry for printing a stack trace.
