[PATCH v3 3/8] arm64: irqflags: Add condition flags to inline asm clobber list

From: Julien Thierry
Date: Thu Jun 06 2019 - 05:36:20 EST


Some of the inline assembly instruction use the condition flags and need
to include "cc" in the clobber list.

Fixes: commit 4a503217ce37 ("arm64: irqflags: Use ICC_PMR_EL1 for interrupt masking")
