commit87e7e25aeeupstream. In order to remember how to unmap a memory (as single or as page), we maintain a bit per Transmit Buffer (TBs) in the meta data (structure iwl_cmd_meta). We maintain a bitmap: 1 bit per TB. If the TB is set, we will free the memory as a page. This bitmap was never cleared. Fix this.

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.
