Ingo Molnar 4270fd8b4c x86/boot/e820: Move the memblock_find_dma_reserve() function and rename it to memblock_set_dma_reserve() We introduced memblock_find_dma_reserve() in this commit: `6f2a75369e` x86, memblock: Use memblock_memory_size()/memblock_free_memory_size() to get correct dma_reserve But there's several problems with it: - The changelog is full of typos and is incomprehensible in general, and the comments in the code are not much better either. - The function was inexplicably placed into e820.c, while it has very little connection to the E820 table: when we call memblock_find_dma_reserve() then memblock is already set up and we are not using the E820 table anymore. - The function is a wrapper around set_dma_reserve(), but changed the 'set' name to 'find' - actively misleading about its primary purpose, which is still to set the DMA-reserve value. - The function is limited to 64-bit systems, but neither the changelog nor the comments explain why. The change would appear to be relevant to 32-bit systems as well, as the ISA DMA zone is the first 16 MB of RAM. So address some of these problems: - Move it into arch/x86/mm/init.c, next to the other zone setup related functions. - Clean up the code flow and names of local variables a bit. - Rename it to memblock_set_dma_reserve() - Improve the comments. No change in functionality. Enabling it for 32-bit systems is left for a separate patch.

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.
