[Xen-devel] [PATCH v3] arm: irq: increase size of irq from uint8_t to uint32_t

[Iurii Konovalenko <iurii.konovalenko@xxxxxxxxxxxxxxx>]

From: Iurii Konovalenko <iurii.konovalenko@xxxxxxxxxxxxxxx>

Changes are dedicated to XEN_DOMCTL_irq_permission and
IRQ pssthrough API functions.

PHYSDEV_* operations already using 32 bits type but signed one.

Although, PHYSDEV_* operations are not yet used on ARM and LPIs support
(which are using very high number) are not supported yet, we don't need
to care about theses for now.

Signed-off-by: Iurii Konovalenko <iurii.konovalenko@xxxxxxxxxxxxxxx>
