[RFC PATCH 0/2] kernel: Drop pm_poweroff_prepare
From: Guenter Roeck

While working on the poweroff handler implementation, I also started looking
into pm_power_off_prepare. Ultimately, I concluded that it is not really
necessary, and that it would be easy to remove.
The first patch in this series converts acpi to use a syscore callback
instead of setting pm_power_off_prepare. Since acpi is the only user of
pm_power_off_prepare, it is no longer used and removed with the second
Removing pm_power_off_prepare streamlines poweroff handling and makes it
more uniform, so I think its removal would be worthwhile to consider.
I am sending the series as RFC since I am not sure if I may be missing
something. Compile tested only at this time; I'll do more testing if this
sounds like a reasonable thing to do.
On a side note, I don't see any callers of acpi_suspend(). I actually
removed it as an experiment, and at least x86_64:allmodconfig still
compiles. Can it be removed ?
