[ Upstream commit4fb54994b2] The base address of a DSO mapping should start at the start of the file. Usually DSOs are mapped from the pgoff 0 so it doesn't matter when it uses the start of the map address. But generated DSOs for JIT codes doesn't start from the 0 so it should subtract the offset to calculate the .eh_frame table offsets correctly.

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.
