Introduce a new file to implement collection of hypervisor RAM into the vmcore collected by linux. By default, the hypervisor RAM is locked, ie, protected via hw page table. Hyper-V implements a disable hypercall which essentially devirtualizes the system on the fly. This mechanism makes the hypervisor RAM accessible to linux. Because the hypervisor RAM is already mapped into linux address space (as reserved RAM), it is automatically collected into the vmcore without extra work. More details of the implementation are available in the file prologue. Signed-off-by: Mukesh Rathor <mrathor@linux.microsoft.com> Signed-off-by: Wei Liu <wei.liu@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 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.
