Subject: Re: [PATCH v4 03/32] scsi: hisi_sas: add initial bare main driver
I'll follow up with a fix in patchset v5. However kernel linking seems
broken for this config without my patches.
arch/x86/built-in.o: In function `hv_machine_crash_shutdown':
mshyperv.c:(.text+0xa1ec4): undefined reference to
`native_machine_crash_shutdown'
