Aside from any race conditions that might exist between switch_mm() and an IRQ, there is also an unconditional hard_irq_disable() in switch_slb(). If that isn't followed at some point by an IRQ enable then interrupts will remain disabled until we return to userspace. It is true that when switch_mm() is called from the scheduler IRQs are off, but not when it's called by use_mm(). Looking closer we see that last year in commit f98db6013c55 ("sched/core: Add switch_mm_irqs_off() and use it in the scheduler") this was made more explicit by the addition of switch_mm_irqs_off() which is now called by the scheduler, vs switch_mm() which is used by use_mm(). Arguably it is a bug in use_mm() to call switch_mm() in a different context than it expects, but fixing that will take time. This was discovered recently when vhost started throwing warnings such as: BUG: sleeping function called from invalid context at kernel/mutex.c:578 in_atomic(): 0, irqs_disabled(): 1, pid: 10768, name: vhost-10760 no locks held by vhost-10760/10768. irq event stamp: 10 hardirqs last enabled at (9): _raw_spin_unlock_irq+0x40/0x80 hardirqs last disabled at (10): switch_slb+0x2e4/0x490 softirqs last enabled at (0): copy_process+0x5e8/0x1260 softirqs last disabled at (0): (null) Call Trace: show_stack+0x88/0x390 (unreliable) dump_stack+0x30/0x44 __might_sleep+0x1c4/0x2d0 mutex_lock_nested+0x74/0x5c0 cgroup_attach_task_all+0x5c/0x180 vhost_attach_cgroups_work+0x58/0x80 [vhost] vhost_worker+0x24c/0x3d0 [vhost] kthread+0xec/0x100 ret_from_kernel_thread+0x5c/0xd4 Prior to commit 04b96e5528ca ("vhost: lockless enqueuing") (Aug 2016) the vhost_worker() would do a spin_unlock_irq() not long after calling use_mm(), which had the effect of reenabling IRQs. Since that commit removed the locking in vhost_worker() the body of the vhost_worker() loop now runs with interrupts off causing the warnings. This patch addresses the problem by making the powerpc code mirror the x86 code, ie. we disable interrupts in switch_mm(), and optimise the scheduler case by defining switch_mm_irqs_off().
