Subject: [PATCH 9/10] Time: i386 Conversion - part 5: ACPI PM variable renaming and config change.
Date: Thu, 5 Jan 2006 19:14:28 -0700	[thread overview]
Message-ID: <20060106021427.6714.56739.sendpatchset@cog.beaverton.ibm.com> (raw)
In-Reply-To: <20060106021328.6714.45831.sendpatchset@cog.beaverton.ibm.com>

	This cleans up some of the variable names used in the old ACPI 
PM timer_opts code. Specifically, it renames pmtmr_ioport and removes 
the CONFIG_X86_PM_TIMER option.

thanks
-john
