From: Alexandru Moise <alexandru.t.mo...@gmail.com>
I wanted to build kernel modules on my riscv target,
cd /usr/src/kernel/
make scripts prepare
<...>
CC scripts/mod/devicetable-offsets.s
UPD scripts/mod/devicetable-offsets.h
HOSTCC scripts/mod/file2alias.o
HOSTCC scripts/mod/sumversion.o
HOSTLD scripts/mod/modpost
CC kernel/bounds.s
/bin/sh: line 1: arch/riscv/kernel/asm-offsets.s: No such file or directory
make[1]: *** [Kbuild:37: include/generated/asm-offsets.h] Error 1
make: *** [Makefile:1219: prepare0] Error 2
The patch just adds the asm-offsets.s file for riscv targets.
With this the prepare target succeeds:
make scripts prepare
<...>
CC kernel/bounds.s
CALL scripts/checksyscalls.sh
CALL scripts/atomic/check-atomics.sh
LDS arch/riscv/kernel/vdso/vdso.lds
AS arch/riscv/kernel/vdso/rt_sigreturn.o
CC arch/riscv/kernel/vdso/vgettimeofday.o
AS arch/riscv/kernel/vdso/getcpu.o
AS arch/riscv/kernel/vdso/flush_icache.o
AS arch/riscv/kernel/vdso/note.o
VDSOLD arch/riscv/kernel/vdso/vdso.so.dbg
VDSOSYM include/generated/vdso-offsets.h
