UEFI specification states that on IA-32 paging may or may not be
enabled during startup. If paging is enabled, PAE might be active.
During jump to kernel and early kernel initialiation we use paging
without PAE.
Therefore the following initialization sequence is introduced:
* disable paging
* disable PAE
* load page directory
* enable paging

The stat structure fields are not standardized, so we can't use an
hardcoded field name. The code in all other places was already adjusted
with a macro to handle the access, but hrev55802 introduced a new place
where we need to read the access and modification times. Use the macro
there as well.
Thanks to anuragpd4 for reporting the problem!

This way, applications blocked in usb_raw can actually be killed,
instead of "hanging" until the USB device is removed or the
transfer finishes.
Improves a number of USB tickets, but does not really "fix"
any of the underlying problems that lead to this happening.
We have used and had fallback futimens() implementations in libroot_build
(and in this file even) for over a decade, but nobody seems to have noticed
this bit of missing functionality which can be implemented with them.
In fact, this is rather important bit of functionality, as "copyattr"
relies on it to preserve the mtimes of copied files; and we use
recursive copyattr many places in Haiku builds. Thus, the lack of
an implementation here was the cause of all files in built Haiku images
having timestamps of whenever the build was done, and not whenever
the file was actually modified.
This should make development on Haiku nightlies much more pleasant,
as the system headers from the haiku_devel package should no longer
have always-current timestamps with every upgrade.
First try to allocate a page below 2GB.
If it fails, try to allocate a physical page at the address
returned by get_next_virtual_address so that we get an address
that is available in both virtual and physical space.
Finally try to allocate any available page. At this point
it's highly likely that it will be above 0x88000000 so it can be
used for trampoline code.

All the regions allocated via platform_allocate_region() are mapped to a
high virtual address so there's no need to do identity mapping for them
any more.
Copy kernel_args to a region allocated via platform_allocate_region() so it
will be mapped similarly.
Identity mapping is still needed for trampoline code for jumping to the kernel

EFI runtime service memory areas are remapped to a high virtual address
allocated with get_next_virtual_address() to avoid any address space
collision.
They are also added to virtual_ranges_to_keep so that the kernel knows

The initial page tables have to satisfy the following conditions instead:
* the inital page tables shall be allocated in the same region as the initial page directory
* this region shall be mapped contiguously
* the page tables shall be mapped at a higher address than the page directory
