Fork of reMarkable kernel https://github.com/reMarkable/linux

In order to fetch the correct entry point with the ISA bit included, for use by non-ELF boot loaders, parse the output of `objdump -f' for the start address recorded in the kernel executable itself, rather than using `nm' to get the value of the `kernel_entry' symbol. Sign-extend the address retrieved if 32-bit, so that execution is correctly started on 64-bit processors as well. The tool always prints the entry point using either 8 or 16 hexadecimal digits, matching the address width (aka class) of the ELF file, even in the presence of leading zeros. Signed-off-by: Maciej W.

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.
