This reverts the following commits:1ea66554d3("x86/mm: Mark p4d_offset() __always_inline")046c0dbec0("x86: Mark native_set_p4d() as __always_inline") p4d_offset(), native_set_p4d() and native_p4d_clear() were marked __always_inline in attempt to move __pgtable_l5_enabled into __initdata section. It was required as KASAN initialization code is a user of USE_EARLY_PGTABLE_L5, so all pgtable_l5_enabled() translated to __pgtable_l5_enabled there. This includes pgtable_l5_enabled() called from inline p4d helpers. If compiler would decided to not inline these p4d helpers, but leave them standalone, we end up with section mismatch. We don't need __always_inline here anymore. __pgtable_l5_enabled moved back to be __ro_after_init.

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.
