Fix the ACPI/PCI legacy interrupts (INTx) parsing in the cases when the ACPI Global System Interrupt (GSI) value is a 32-bit one with the MSB set that is interpreted as a negative integer and causes acpi_pci_link_allocate_irq() to fail and acpi_irq_get_penalty() to trigger an out-of-bounds array dereference (Lorenzo Pieralisi) -----BEGIN PGP SIGNATURE----- iQFGBAABCAAwFiEEcM8Aw/RY0dgsiRUR7l+9nS/U47UFAmlhHEMSHHJqd0Byand5 c29ja2kubmV0AAoJEO5fvZ0v1OO1sSIIAK1NeCVdGg9YpInOmVSneDENsaWReo9c ZxJBKISVPkiwG+8jEbPgIJJcwAXGBgzYBOA/l2S8TkFjj3h6yRidKI2PUabW49KA LN0k1Xkts/W4EVvY4d2J5WdNCwzzPi+cxG5fDuL5izZNP4yKJxiOvEybUAmA6i9g EqKXnAme/qSGSfZKFltjKDu9OcV+Nq1MSezl5h4JffChIXyJ1vX5tGmM3ENxzwXN gBUMk3BKD1TnnmjVO8Cz1WV8oDszOY3Y2+8MBGkbB5P/6Kwkdf2Wh79voddozi3D i+kJxdAJBqsUFODprhIYmgYR5duvi8XOj6p94hLzu8yJvvStYcqudRs= =v1UK -----END PGP SIGNATURE----- Merge tag 'acpi-6.19-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI support fix from Rafael Wysocki: "This fixes the ACPI/PCI legacy interrupts (INTx) parsing in the case when the ACPI Global System Interrupt (GSI) value is a 32-bit one with the MSB set.
