Subject: ARM: SMP: remove send_ipi_message()
X-Git-Tag: 2.1b_release~5942^2~2^2^2~30
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e3fbb087650df130788d8e3ac29875ee56819249;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git

ARM: SMP: remove send_ipi_message()

send_ipi_message() does nothing except call smp_cross_call().  As
this is a static function, nothing external to this file calls it,
so we can easily clean up this now unnecessary indirection.
