Hello, Linus.
Just one patch to work around CRIS boot problem caused by a recent
change which freed a temporary boot data structure. The root cause is
on CRIS side but it doesn't seem trivial to fix. For now, work around
by skipping freeing on CRIS.
Thanks.

Commit 4d4bbd8526a8 ("mm, oom_reaper: skip mm structs with mmu notifiers")
prevented the oom reaper from unmapping private anonymous memory with the
oom reaper when the oom victim mm had mmu notifiers registered.
The rationale is that doing mmu_notifier_invalidate_range_{start,end}()

This uses the new annotation to determine if an mm has mmu notifiers with
blockable invalidate range callbacks to avoid oom reaping. Otherwise, the
callbacks are used around unmap_page_range().

Per SLIMbus specification, a reconfiguration sequence known as
'clock pause' needs to be broadcast over the bus while entering low-

To exit clock-pause, controller typically wakes up the framer device.
