- A single fix for ASMedia HBAs.
These HBAs do not indicate that they support SATA Port Multipliers
CAP.SPM (Supports Port Multiplier) is not set.
Likewise, they do not allow you to probe the devices behind an
attached PMP, as defined according to the SATA-IO PMP specification.
Instead, they have decided to implement their own version of PMP,
and because of this, plugging in a PMP actually works, even if the
HBA claims that it does not support PMP.
Revert a recent quirk for these HBAs, as that breaks ASMedia's own
implementation of PMP.
Unfortunately, this will once again give some users of these HBAs
significantly increased boot time. However, a longer boot time for
some, is the lesser evil compared to some other users not being able
to detect their drives at all.

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.
