Subject: [IA64] remove CONFIG_SMP ifdef in ia64_send_ipi()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd3244e605efeb13bb3a6e92439974832e1c7388;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[IA64] remove CONFIG_SMP ifdef in ia64_send_ipi()

When !CONFIG_SMP, cpu_physical_id() is ia64_get_lid(), which is
functionally identical to

    (ia64_getreg(_IA64_REG_CR_LID) >> 16) & 0xffff

so there's no need for two versions of this code.
