The Intel Compute Stick STCK1A8LFC and Weibu F3C platforms both log 2 error messages during boot: efi: requested map not found. esrt: ESRT header is not in the memory map. Searching the web, this seems to affect many other platforms too. Since these messages are logged as errors, they appear on-screen during the boot process even when using the "quiet" boot parameter used by distros. Demote the ESRT error to a warning so that it does not appear on-screen, and delete the error logging from efi_mem_desc_lookup; both callsites of that function log more specific messages upon failure. Out of curiosity I looked closer at the Weibu F3C. There is no entry in the UEFI-provided memory map which corresponds to the ESRT pointer, but hacking the code to map it anyway, the ESRT does appear to be valid with 2 entries.

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.
