Subject: x86: make ipi_handler() always defined
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4e2947f12516d13446d6ffa1d9e4fbd33b1636fa;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86: make ipi_handler() always defined

prepare for up_smp_call_function() to ensure that the 'func'
pointer is unused. (which is related to a KVM build fix)
