commit 513f7f747e1cba81f28a436911fba0b485878ebd upstream. Sven noticed that calling ioremap() and iounmap() multiple times leads to a vmap memory leak: vmap allocation for size 4198400 failed: use vmalloc=<size> to increase size It seems we missed calling vunmap() in iounmap().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
