From: Jack Steiner Date: Wed, 9 Sep 2009 15:41:05 +0000 (-0500) Subject: x86: SGI UV: Fix IPI macros X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2374aecda3f6c9b0d13287027132a37311da300;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git x86: SGI UV: Fix IPI macros The UV BIOS has changed the way interrupt remapping is being done. This affects the id used for sending IPIs. The upper id bits no longer need to be masked off.
