Recently few issues were noticed in the code where CONFIG_OF wasn't
consistently used for many routines. The core file is big enough now and
ifdef hackery makes it less readable.
Move OF specific code to another file and compile that only if CONFIG_OF
is enabled.
Compile-tested:
- For ARM (exynos) with CONFIG_OF enabled
- For X86 with CONFIG_OF disabled (have to enable CONFIG_PM_OPP separately)
No functional changes.

arch_pick_mmap_layout is only called by fs/exec.c which is always built into
kernel, it looks the EXPORT_SYMBOL_GPL is pointless and no architectures export
it other than ARM64.

Hi Folks,
Some LLVM debugger developers would like to add unaligned as well as
scoped watchpoints and it seems they need some additional support in
the kernel to do so.
I'm not claiming to understand what they need, since GDB already
supports it, it may be possible to do it with the current kernel.
However, if there's a better way to do it, than I think it may be
worth checking with them. If not, I'd appreciate if someone could help
them understanding how they could do it with the current structure.
https://bugzilla.kernel.org/show_bug.cgi?id=117621
Both unaligned and scoped watchpoints require the same level of
functionality: watch over a larger area and defer to a software
implementation (table look-up) to see if it's a true or false
positive.
For unaligned watchpoints, we'd need to watch over the area
+-alignment then factor out the padding. For scoped watchpoints, we
need to watch over the stack and always check if the variable is in
scope or not by comparing it to the stack pointer / frame pointer /
base pointer.
I don't think either of them would have to be implemented in the
kernel itself, I'm expecting this to be in the debuggers code, but
they may need additional logic in the kernel, which Pavel and Omair
should know better.
This email is so that I don't prematurely add irrelevant people to the bug. :)
Thanks!
