[ Upstream commit 6489f8d0e1d93a3603d8dad8125797559e4cf2a2 ] During boot time kernel configured with OF=y but USE_OF=n displays the following warnings and hangs shortly after starting userspace: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at kernel/irq/irqdomain.c:695 irq_create_mapping_affinity+0x29/0xc0 irq_create_mapping_affinity(, 6) called with NULL domain CPU: 0 PID: 0 Comm: swapper Not tainted 5.15.0-rc3-00001-gd67ed2510d28 #30 Call Trace: __warn+0x69/0xc4 warn_slowpath_fmt+0x6c/0x94 irq_create_mapping_affinity+0x29/0xc0 local_timer_setup+0x40/0x88 time_init+0xb1/0xe8 start_kernel+0x31d/0x3f4 _startup+0x13b/0x13b ---[ end trace 1e6630e1c5eda35b ]--- ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at arch/xtensa/kernel/time.c:141 local_timer_setup+0x58/0x88 error: can't map timer irq CPU: 0 PID: 0 Comm: swapper Tainted: G W 5.15.0-rc3-00001-gd67ed2510d28 #30 Call Trace: __warn+0x69/0xc4 warn_slowpath_fmt+0x6c/0x94 local_timer_setup+0x58/0x88 time_init+0xb1/0xe8 start_kernel+0x31d/0x3f4 _startup+0x13b/0x13b ---[ end trace 1e6630e1c5eda35c ]--- Failed to request irq 0 (timer) Fix that by calling irqchip_init only when CONFIG_USE_OF is selected and calling legacy interrupt controller init otherwise.
