: pKVM memory transition simplifications, courtesy of Quentin Perret.
:
: From the cover letter:
: "Since its early days, pKVM has formalized memory 'transitions' (shares
: and donations) using 'struct pkvm_mem_transition' and bunch of helpers
: to manipulate it. The intention was for all transitions to use this
: machinery to ensure we're checking things consistently. However, as
: development progressed, it became clear that the rigidity of this model
: made it really difficult to use in some use-cases which ended-up
: side-stepping it entirely. That is the case for the
: hyp_{un}pin_shared_mem() and host_{un}share_guest() paths upstream which
: use lower level helpers directly, as well as for several other pKVM
: features that should land upstream in the future (ex: when a guest
: relinquishes a page during ballooning, when annotating a page that is
: being DMA'd to, ...). On top of this, the pkvm_mem_transition machinery
: requires a lot of boilerplate which makes the code hard to read, but
: also adds layers of indirection that no compilers seems to see through,
: hence leading to suboptimal generated code.
:
: Given all the above, this series removes the pkvm_mem_transition
: machinery from mem_protect.c, and converts all its users to use
: __*_{check,set}_page_state_range() low-level helpers directly."

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 reStructuredText 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.
