It checks whether the page or page's data is present in an underlying
"backing store", not whether the page is present in the cache itself.
No functional change intended.
The previous logic, which dates back to the NewOS kernel, inserted them
into the deepest cache instead if the fault was a read and not a write.
But this creates problems if the deepest cache is of a smaller size than
the topmost cache, because then we'll be inserting pages with offsets
past the cache's virtual_end. In the case there are multiple levels of
caches between the topmost and the deepest cache which all are smaller
than the topmost, then when/if the deepest cache is merged with the second-
deepest cache, those pages will get skipped and freed when they may still
be in-use, which was the cause of #19367.
To solve this, just insert new pages into the topmost cache always.
Inserting them into the deepest cache seems to have been an optimization
(and a savings of pages), and not a matter of correctness.
Move ColorListView and ColorItem to shared in BPrivate namespace.
ColorItem typedef to BPrivate::BColorItem for apps that are already
using this class.
Gravity screensaver:
* ColorItem => BColorItem.
* Use make_color() to set colors.
Make color drop message name agnostic, check for B_RGB_COLOR_TYPE.
Add be:sender and source to drag message.
Add _SetTermColors() convenience method to set colors on all tabs.

AdoptSystemColors() tints document background color to match panel
color if uneditable.
Calling MakeEditable() will automatically apply or unapply uneditable
background tint if you have previously called AdoptSystemColors().
Parent BView::AdoptSystemColors() sets panel colors, we want document
colors here. Do not alter text color - only view, low and high colors
are changed.
Document AdoptSystemColors() and MakeEditable() in BTextView docs.

* Use a "null" cache and avoid committing memory unnecessarily.
* Block the 64-bit ranges also. On x86_64 the kernel is above
userspace, so we have to |= KERNEL_BASE here; but in case
something actually tries to access those pointers directly
they should get a GPE anyway (as the address should be outside
the canonical range.) If it's not, then SMAP should catch it.
We don't have many etc and non-etc syscall pairs in this file
(the semaphores seem to be a notable exception), so drop
wait_for_thread and just call wait_for_thread_etc instead.
This breaks syscall ABI, but we've already broken it since beta5
anyway.
They're still mapped into the team address space and with user addresses,
of course, and we reset all their protections later on anyway. This allows
a number of arch_cpu_{enable|disable}_user_access() calls to be dropped.
Also adjust the name of ro/text segments to "rx" to match what
runtime_loader now does.
Tested with SMAP enabled, still works.
If it's not set (and we aren't on pre-Haiku GCC2 ABI), then don't make
the region executable.
This mostly only makes a difference for Clang/LLD-linked binaries
that have a readable, non-writable, non-executable program segment.
GCC/LD-linked binaries just have all read-only data in the main
read+execute section by default.
... and B_DOCUMENT_TEXT_COLOR with the selected hand using
B_NAVIGATION_BASE_COLOR when dragging instead of blue
(well, it is still blue but customizable).
Analog clock colors adjusted for light and dark modes.

If we don't have an Entry to attach/detach from, then we don't need
to acquire any locks at all. Now that we return multiple dirents
from read_dir, it's much more likely that we wind up with
EntryIterators in such a state, so this avoids some lock contention.
Like S_IFIFO. It doesn't support ones with "sub-vnodes", but FIFOs
and UNIX sockets don't seem to use those (does anything, actually?)

This solves some TODOs and allows image_debug_lookup_user_symbol_address
to be dropped entirely. It should also fix reading symbols from binaries
that have multiple TEXT regions, and most functions are not in the first.
