Kernel:
* physical memory mapper uses kernel read/write mapping
with no-execute bit enabled
* all other pages are mapped as read/write/execute for
kernel and user
* proper access permissions and memory types to be
implemented later
Enforce memory access permissions by setting DACR to

The old implementation used the real lock_memory(). This is problematic
and does not work for a large number of reasons:
1) Various parts of the kernel assume memory is locked only very
temporarily, and will often wait on locked memory to become unlocked.
The transient nature of locks is further demonstrated by the fact that
lock_memory acquires references to structures, like the address space,
which are only released by unlock_memory
2) The VM has a hard assumption that all lock_memory calls will be
exactly balanced, and maintains internal "WiredRange" structures
on areas, etc. corresponding to the original lock_memory calls.
Maintaining separate data structures as this code did is a recipe
for even more problems when the structures are manipulated separately,
leading to confusing or incorrect behavior on unlocks.
3) Areas with locked memory cannot be deleted, nor can the pages which are
locked be removed from the areas/caches. This of course is most notable
when destroying teams which locked memory, but the problem also occurs
when just using delete_area, resize_area, mmap/munmap, etc.
Because of (2) and especially (3), adding support for mlock()-like semantics
to the existing memory locking system is just not a good option. A further
reason is that our lock_memory is much stricter than mlock(), which only
demands the pages in question must remain resident in RAM and cannot be
swapped out (or, it seems, otherwise written back to disk.)
Thus, this commit completely removes the old implementation (which
was seriously broken and did not actually automatically unlock memory
on team exit or area destruction at all, etc.) and instead adds a new
feature to VMAnonymousCache to block certain pages from being written out.
The syscall then just invokes this to do its work.
Fixes#17674. Related to #13651.

This reverts commit 8497a2cc28.
The VFS layer is not at all ready for this. Many places in the
code implicitly assume ino_t values will never change. This
functionality is only necessary for live shrinking of partitions,
which is a feature niche enough we do not need to worry about
implementing it in the first round of resizing (if ever.)
Part of the point of published variables is to make them "shareable",
and not require external synchronization. Requiring the callers
to ensure unpublishing does not occur is thus unreasonable, as e.g.
a variable could be unpublished immediately after being notified.
That is the case for some usages of these variables in the FreeBSD
compatibility layer, which under heavy usage, can and did trigger
use-after-unpublishes and then KDLs, at least in local testing.
Instead, only unlock the hash after we have locked the variable.
This is already done in some other functions, so it's safe to do
it here, too. This way, the variable won't be unpublished
while Notify() is running.
Get the OEM string from the VESA info block (and also get the memory
size from there while we are at it). If the string is empty, use the
BIOS type (identified in other ways) to still report something.

The VESA standard does not define any way for software to set a custom
video mode, which means normally we would be constrained to whichever
modes the video card manufacturer decided to provide. However, since we
run the BIOS in an emulated environment, it is possible (and even quite
easy) to patch it and inject any video mode we want, provided we know
the format to use and where to put the info in.
This approach was used in the NewOS VESA driver, as well as in
915resolution (a tool that predates the availability of native drivers
for Linux for Intel videocards). Later on it was also used in Chameleon
and Clover, bootloaders that are used for hackintoshes (running MacOS on
unsupported hardware).
This commit implements full support for Intel cards only, AMD and NVidia
will be added later (but there is preliminary code to detect them)
