From: Roger Pau Monné Date: Wed, 30 Aug 2023 08:03:53 +0000 (+0200) Subject: x86/irq: fix reporting of spurious i8259 interrupts X-Git-Tag: 4.18.0-rc1~128 X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=709f6c8ce6422475c372e67507606170a31ccb65;p=xen.git x86/irq: fix reporting of spurious i8259 interrupts The return value of bogus_8259A_irq() is wrong: the function will return `true` when the IRQ is real and `false` when it's a spurious IRQ. This causes the "No irq handler for vector ..." message in do_IRQ() to be printed for spurious i8259 interrupts which is not intended (and not helpful). Fix by inverting the return value of bogus_8259A_irq().
