[patch 04/10] x86/traps: Remove pointless irq enable from do_spurious_interrupt_bug()

[Thomas Gleixner]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

That function returns immediately after conditionally reenabling interrupts which
is more than pointless and requires the ASM code to disable interrupts again.
