Subject: x86, mrst: Set correct APB timer IRQ affinity for secondary cpu
X-Git-Tag: v2.6.37.2~36
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8cc8e3f986fcb39f707e32f68d12a896f673dba0;p=pandora-kernel.git

x86, mrst: Set correct APB timer IRQ affinity for secondary cpu

This is a backport for 2.6.37 stable. The original commit ID is
6550904ddbc3c286798a87edf95eeebcc62bc58a

Offlining the secondary CPU causes the timer irq affinity to be set to
CPU 0. When the secondary CPU is back online again, the wrong irq
affinity will be used.

This patch ensures secondary per CPU timer always has the correct
IRQ affinity when enabled.
