Hi,
ACPI Kconfig cleanup, few updates and mostly typos.
- fix CONFIG_ACPI description
- excuse me, but I thought that CONFIG_ACPI_SLEEP has been ok for
almost half a decade now? --> Remove misleading text.
- mention brokenness of some older Intel chipsets in CONFIG_X86_PM_TIMER
- spelling / cleanup
Patch against 2.6.22-rc1-mm1, however I'd want this to end up in
acpi-linux-2.6 (and thus 2.6.23 probably),
hopefully there are no conflicts.
Thanks!
