release
Fixes regressions -- a build failure, an oops, some dmesg spam.
Also fixes some D-state issues and adds ACPI module auto-loading.
Yes, I'd hoped to get the last two in before rc1.
I'm hopeful that a couple-days into rc2 is sufficiently early for them.
I hate pulling this, but I did. However, what I hate even more after
having done so is that ACPI now seems to select CPU hotplug. Why?
That is just *broken*. Sure, if you select STR or hibernation, we need CPU
hotplug,
You are kidding, right? CPU hotplug is broken big time; it kills a machine
like virus-scanner. I always turn it of as a rule. And now you want
STR/STD to be dependent on it? Even on UP? Why?
CPU_HOTPLUG is needed to take the non-boot processors off-line before the suspend,
and to bring them on-line upon the resume. If you have specific problems
with bringing logical processors offline and online, then please speak up
because many are depending on this functionality working.
nobody is arguing that CPU_HOTPLUG should not be a requirement for
suspend, what we are questioning is why simply enabling ACPI should
require CPU_HOTPLUG.
not everyone who configures ACPI wants to use suspend (of any flavor)
