Break out the code to create an aligned page allocation from mem.c and move it into a function efi_allocate_pages_aligned() in alignedmem.c. Update efi_allocate_pages() to invoke it unless the minimum alignment equals the EFI page size (4 KB), in which case the ordinary page allocator is sufficient. This way, efi_allocate_pages_aligned() will only be pulled into the build if it is actually being used (which will be on arm64 only in the immediate future) Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
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.
