nohz: Fix another inconsistency between CONFIG_NO_HZ=n and nohz=off
If CONFIG_NO_HZ=n tick_nohz_get_sleep_length() returns NSEC_PER_SEC/HZ.
If CONFIG_NO_HZ=y and the nohz functionality is disabled via the
command line option "nohz=off" or not enabled due to missing hardware
support, then tick_nohz_get_sleep_length() returns 0. That happens
because ts->sleep_length is never set in that case.
Set it to NSEC_PER_SEC/HZ when the NOHZ mode is inactive.

Title:
Unable to boot from installation media
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've been using Ubuntu 12.04 on my desktop for a number of years now.
When I installed it, I had to pass the kernel option acpi=off in order
to get it to boot correctly, both from the live CD and after
installation. Otherwise, it has worked well (obviously, without ACPI
features being present).
I am now trying to install my OS from scratch, and am attempting to do
so with 14.04. However, I have been completely unable to get the
system to boot into the installer without freezing or rebooting. I
have tried the kernel options nolapic, noapic, acpi=off, acpi=ht, and
irqpoll, in a large number of combination, and both with a BIOS and
UEFI boot. I also flashed my BIOS to the latest firmware, which seems
to have made the boot process last a bit longer before freeze/reboot,
but given that I never timed it, that's a very non-scientific
assessment.
I've tried booting with Debian, Fedora, and ArchLinux disks as well,
all to no avail, so I do not believe this is an Ubuntu-specific issue.
It seems that there's been some kernel level change since 12.04
causing issues. I'm hoping that there's some workaround or kernel boot
option to be passed in.
I'm not certain what the most useful information to provide is. Since
I'm currently running from Ubuntu 12.04, I can run any command that OS
supports to provide you with more system information. In case it's
useful, I've attached the output of dmidecode.
My motherboard is an MSI H77MA-G43.
