[PATCH 3/7] kvm: Move kvm_spurious_fault dec out of x86

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The routine kvm_spurious_fault() is a common kvm routine, so
move its declaration from arch/x86/include/asm/kvm_host.h to
arch/arm/include/asm/kvm_host.h.

Fixes sparse warning when building on arm64:

  virt/kvm/kvm_main.c:warning: symbol 'kvm_spurious_fault' was not declared. Should it be static?
