Samuel Holland <samuel.holland@sifive.com> says: Currently, RISC-V NOMMU kernels are linked at CONFIG_PAGE_OFFSET, and since they are not relocatable, must be loaded at this address as well. CONFIG_PAGE_OFFSET is not a user-visible Kconfig option, so its value is not obvious, and users must patch the kernel source if they want to load it at a different address. Make NOMMU kernels more portable by making them relocatable by default. This allows a single kernel binary to work when loaded at any address. * b4-shazam-merge: riscv: Remove CONFIG_PAGE_OFFSET riscv: Support CONFIG_RELOCATABLE on riscv32 asm-generic: Always define Elf_Rel and Elf_Rela riscv: Support CONFIG_RELOCATABLE on NOMMU riscv: Allow NOMMU kernels to access all of RAM riscv: Remove duplicate CONFIG_PAGE_OFFSET definition Link: https://lore.kernel.org/r/20241026171441.3047904-1-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
