Subject: i386: export i386 smp_call_function_mask() to modules
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6442eea937ef797d4b66733f49c82e2fdc2aca6f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

i386: export i386 smp_call_function_mask() to modules

This patch export i386 smp_call_function_mask() with EXPORT_SYMBOL().

This function is needed by KVM to call a function on a set of CPUs.
