 [PATCH v1 0/4] ACPI: scan: Check enabled _STA bit on Bus/Device Checks

Hi,

This series adds _STA enabled bit checking for processors (in all cases)
and for all devices in the Bus Check and Device Check notification handling
paths.  It does so without any side-effects on non-processor devices, unlike

https://lore.kernel.org/linux-acpi/E1rVDmP-0027YJ-EW@rmk-PC.armlinux.org.uk/

The first patch fixes an issue with failing Device Check notifications
without a valid reason.

The next two patches together make Bus Check and Device Check notification
handling take the enabled bit into account.

The last patch modifies the processor scan handler to check the enabled bit
it its add callback.

I would appreciate testing this on a system where the enabled bit really
matters.

Thanks!
