commit b59711e9b0d22fd47abfa00602fd8c365cdd3ab7 upstream.
During perf inject --jit, JIT_CODE_MOVE records were injecting MMAP records
with an incorrect filename. Specifically it was missing the ".so" suffix.
Further the JIT_CODE_LOAD record were silently truncating the
jr->load.code_index field to 32 bits before generating the filename.
Make both records emit the same filename based on the full 64 bit
code_index field.
Fixes: 9b07e27f88b9 ("perf inject: Add jitdump mmap injection support")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
