From: Alexander van Heukelum Date: Tue, 9 Sep 2008 19:56:18 +0000 (+0200) Subject: i386: trace_hardirqs_fixup should now not be necessary: irqs are off. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=07bb2f6236f11169fbd8a8916b16715b25fea9b6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git i386: trace_hardirqs_fixup should now not be necessary: irqs are off. The exception handlers in entry_32.S should now all call TRACE_IRQS_OFF before calling the C code. The calls to trace_hardirqs_fixup should now be unnecessary. Remove them.
