Subject: [PM] Split SOFTWARE_SUSPEND and ACPI_SLEEP
Date: Sun, 27 Jul 2003 00:39:58 +0200	[thread overview]
Message-ID: <20030726223958.GA473@elf.ucw.cz> (raw)

Hi!

Splits two config options to avoid user confusion. Patrick already has
better version of that patch in his tree, and probably wants to avoid
applying this.
