Subject: [PATCH] Re-map value of NT_RISCV_CSR to not collide with the value of NT_RISCV_VECTOR in Linux kernel header file 'include/uapi/linux/elf.h'
Date: Wed, 9 Aug 2023 10:53:38 -0700 [thread overview]
Message-ID: <20230809175337.1108580-1-greg.savin@sifive.com> (raw)
Linux kernel's file 'include/uapi/linux/elf.h' declares the value 0x900
for NT_RISCV_VECTOR, and does not have a definition for NT_RISCV_CSR, nor
does it use the value 0x901 for any note type. This patch is intended
as a way to resolve the disagreement/collision between Linux and binutils,
over the meaning of 0x900 in the context of note types.
