Merge patch series "riscv: Relocatable NOMMU kernels"

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
