Subject: ppc/85xx: Remove some bogus code from external interrupt handler.
X-Git-Tag: v2010.09-rc1~28^2~7^2~42^2~90
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f761439418f589e16804061edeb848c8ae497091;p=karo-tx-uboot.git

ppc/85xx: Remove some bogus code from external interrupt handler.

Skipping the interrupted instruction will accomplish nothing other
than turning a spurious interrupt into a crash.

External interrupts are not machine checks, so don't count them as such.
