  "message": "x86, ioapic: Add proper legacy interrupt check to mp_map_pin_to_irq()\n\nSince commit bfa644bfa9e3 (x86, irq: Convert IOAPIC to use hierarchy\nirqdomain interfaces) Intel MID platforms crashes on boot:\n\n Enabling APIC mode:  Flat.  Using 1 I/O APICs\n BUG: unable to handle kernel NULL pointer dereference at 00000018\n IP: [\u003cc107bdc6\u003e] __irq_domain_alloc_irqs+0xff/0x250\n\nThe reason is that mp_map_pin_to_irq() assumes blindly that any non\nPCI interrupt is legacy, but thats wrong for MID platforms as they\nhave no legacy interrupt support.\n\nalloc_irq_from_domain() and mp_init_irq_at_boot() have checks for\nthis, but mp_map_pin_to_irq() is lacking one.\n\nInstead of copying the same code another time, move the check to an\ninline function and use it everywhere.\n\n[ tglx: Massaged changelog ]\n\nFixes: bfa644bfa9e3 \u0027x86, irq: Convert IOAPIC to use hierarchy irqdomain interfaces\u0027\nSigned-off-by: Andy Shevchenko \u003candriy.shevchenko@linux.intel.com\u003e\nCc: Jiang Liu \u003cjiang.liu@linux.intel.com\u003e\nCc: Joerg Roedel \u003cjoro@8bytes.org\u003e\nCc: David Cohen \u003cdavid.a.cohen@linux.intel.com\u003e\nLink: http://lkml.kernel.org/r/1418236165-13961-1-git-send-email-andriy.shevchenko@linux.intel.com\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
