[patch V2 01/25] x86/kgbd: Use NMI_VECTOR not APIC_DM_NMI

From: Thomas Gleixner
Date: Thu Jul 04 2019 - 12:34:01 EST


apic->send_IPI_allbutself() takes a vector number as argument.

APIC_DM_NMI is clearly not a vector number. It's defined to 0x400 which is
outside the vector space.

Use NMI_VECTOR instead as that's what it is intended to be.
