Subject: [PATCH] MIPS: fix duplicate definitions for exported symbols
Date: Wed, 2 Nov 2022 20:27:39 +0800 [thread overview]
Message-ID: <Y2JiO+67E1NyFgca@pudh-loong.localdomain> (raw)
Building with clang-14 fails with:
AS arch/mips/kernel/relocate_kernel.o
<unknown>:0: error: symbol 'kexec_args' is already defined
<unknown>:0: error: symbol 'secondary_kexec_args' is already defined
<unknown>:0: error: symbol 'kexec_start_address' is already defined
<unknown>:0: error: symbol 'kexec_indirection_page' is already defined
<unknown>:0: error: symbol 'relocate_new_kernel_size' is already defined
It turns out EXPORT defined in asm/asm.h expands to a symbol definition,
so there is no need to define these symbols again. Remove duplicated
symbol definitions.
Fixes: 7aa1c8f47e7e ("MIPS: kdump: Add support")
