mov_q cannot really move PIE_E[0|1] macros into a general purpose register as expected if those macro constants contain some 128 bit layout elements, that are required for D128 page tables. The primary issue is that for D128, PIE_E[0|1] are defined in terms of 128-bit types with shifting and masking, which the assembler can't accommodate. Instead pre-calculate these PIRE0_EL1/PIR_EL1 constants into asm-offsets.h based PIE_E0_ASM/PIE_E1_ASM which can then be used in arch/arm64/mm/proc.S. While here also drop PTE_MAYBE_NG/PTE_MAYBE_SHARED assembly overrides which are not required any longer, as the compiler toolchains are smart enough to compute both the PIE_[E0|E1]_ASM constants in all scenarios.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
