The patch titled
ACPI: Make /proc/acpi/wakeup interface handle PCI devices (again)
has been removed from the -mm tree. Its filename was
acpi-make-proc-acpi-wakeup-interface-handle-pci-devices-again.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: ACPI: Make /proc/acpi/wakeup interface handle PCI devices (again)
From: Rafael J. Wysocki <rjw@xxxxxxx>
Make the ACPI /proc/acpi/wakeup interface set the appropriate wake-up bits
of physical devices corresponding to the ACPI devices and make those bits
be set initially for devices that are enabled to wake up by default. This
is needed to restore the 2.6.26 and earlier behavior for the PCI devices
that were previously handled correctly with the help of the
/proc/acpi/wakeup interface.
