Linux kernel source tree

In the i5000 and i5400 drivers, the NRECMEMB register is defined as a 16-bit value, which results in wrong shifts in the code, as reported by sparse. In the datasheets ([1], section 3.9.22.20 and [2], section 3.9.22.21), this register is a 32-bit register. A u32 value for the register fixes the wrong shifts warnings and matches the datasheet. Also fix the mask to access to the CAS bits [27:16] in the i5000 driver.

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.
