Subject: [PATCH v2 0/5] riscv: improve link and support ARCH_WANT_LD_ORPHAN_WARN
Date: Thu, 19 Jan 2023 23:54:12 +0800	[thread overview]
Message-ID: <20230119155417.2600-1-jszhang@kernel.org> (raw)

This series tries to improve link time handling of riscv:
patch1 adds the missing RUNTIME_DISCARD_EXIT as suggested by Masahiro.

Similar as other architectures such as x86, arm64 and so on, enable
ARCH_WANT_LD_ORPHAN_WARN to enable linker orphan warnings to prevent
from missing any new sections in future. So the following two patches
are preparation ones, and the last patch finally selects
ARCH_WANT_LD_ORPHAN_WARN

Since v1:
  - add one more patch to catch .init.bss from EFI stub

Jisheng Zhang (5):
  riscv: lds: define RUNTIME_DISCARD_EXIT
  riscv: vmlinux.lds.S: explicitly catch .rela.dyn symbols
  riscv: vmlinux.lds.S: explicitly catch .riscv.attributes sections
  riscv: vmlinux.lds.S: explicitly catch .init.bss sections from EFI
    stub
  riscv: select ARCH_WANT_LD_ORPHAN_WARN for !XIP_KERNEL
