__pgtable_l5_enabled shouldn't be needed after system has booted, we can mark it as __initdata, but it requires preparation. KASAN initialization code is a user of USE_EARLY_PGTABLE_L5, so all pgtable_l5_enabled() translated to __pgtable_l5_enabled there, including the one in p4d_offset(). It may lead to section mismatch, if a compiler would not inline p4d_offset(), but leave it as a standalone function: p4d_offset() is not marked as __init. Marking p4d_offset() as __always_inline fixes the issue. Signed-off-by: Kirill A.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
