However the STATUS32.E[] was not captured correctly as it corresponds to bits [4:1] in the register and not [3:0] Fixes: d9676fa152c83b ("ARCv2: Enable LOCKDEP") Cc: Evgeny Voevodin Signed-off-by: Vineet Gupta --- arch/arc/include/asm/irqflags-arcv2.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arc/include/asm/irqflags-arcv2.h b/arch/arc/include/asm/irqflags-arcv2.h index d1ec7f6b31e0..e880dfa3fcd3 100644 --- a/arch/arc/include/asm/irqflags-arcv2.h +++ b/arch/arc/include/asm/irqflags-arcv2.h @@ -112,7 +112,7 @@ static inline long arch_local_save_flags(void) */ temp = (1 << 5) | ((!!(temp & STATUS_IE_MASK)) << CLRI_STATUS_IE_BIT) | - (temp & CLRI_STATUS_E_MASK); + ((temp >> 1) & CLRI_STATUS_E_MASK); return temp; } -- 2.7.4
