When recovering lines we need to consider that bad blocks in a line affect the emeta area size. Previously it was assumed that the emeta area would grow by the number of sectors per page * number of bad blocks in the line. This assumption is not correct - the number of "extra" pages that are consumed could be both smaller (depending on emeta size) and bigger (depending on the placement of the bad blocks). Fix this by calculating the emeta start by iterating backwards through the line, skipping ppas that map to bad blocks. Also fix the data types used for ppa indices/counts in pblk_recov_l2p_from_emeta - we should use u64.

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.
