patch 2 apply is OK for me, I don't know why you failed :(
Do you have more detals for this?
What did you apply it to? It does not apply for me to riscv/for-next:
https://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git/log/?h=for-next
This 5 patches are based on the master branch of below git:
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git
"git am 0002-RISC-V-Add-arch_crash_save_vmcoreinfo-support.patch" to
this git is ok for me.
All is correct?
I figured out the reason, there is one difference in
arch/riscv/kernel/Makefile between riscv/for-next and torvalds/linux.
For riscv/for-next, in line 81 of arch/riscv/kernel/Makefile, it is:
obj-$(CONFIG_KEXEC) += kexec_relocate.o crash_save_regs.o
machine_kexec.o
But for torvalds/linux, in line 81 of arch/riscv/kernel/Makefile, it is:
obj-$(CONFIG_KEXEC_CORE) += kexec_relocate.o
crash_save_regs.o machine_kexec.o
torvalds/linux is newer than riscv/for-next, commit 3a66a08759
("RISC-V: kexec: Fix build error without CONFIG_KEXEC") added
"CONFIG_KEXEC_CORE" for torvalds/linux, But riscv/for-next
doesn't contain the commit.
Thanks,
Conor.
