Pass the value of make's -j/--jobs argument to pahole, to avoid out of memory errors and make pahole respect the "jobs" value of make. On systems with little memory but many cores, invoking pahole using -j without argument potentially creates too many pahole instances, causing an out-of-memory situation. Instead, we should pass make's "jobs" value as an argument to pahole's -j, which is likely configured to be (much) lower than the actual core count on such systems. If make was invoked without -j, either via cmdline or MAKEFLAGS, then JOBS will be simply empty, resulting in the existing behavior, as expected.

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.
