Refactor align() to work with non-pointers and split into separate helpers for aligning up vs. down. Add align_ptr_up() for use with pointers. Expose all helpers so that they can be used by tests and/or other utilities. The align_down() helper in particular will be used to ensure gpa alignment for hugepages. No functional change intended. [Added sepearate up/down helpers and replaced open-coded alignment bit math throughout the KVM selftests.] Signed-off-by: Sean Christopherson <[email protected]> Signed-off-by: David Matlack <[email protected]> Reviewed-by: Ben Gardon <[email protected]> Message-Id: <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
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.
