The change of ia64's default memory model to SPARSEMEM causes defconfig
build to fail:

1156 | #error Allocator MAX_ORDER exceeds SECTION_SIZE
| ^~~~~
The error cause is the missing definition of PAGE_SHIFT in the calculation
of SECTION_SIZE_BITS.
Add include of <asm/page.h> to arch/ia64/include/asm/sparsemem.h to solve
the problem.

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. 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.
