Message-ID: <20141118065603.22544.88816.stgit@preeti.in.ibm.com> Date: Tue, 18 Nov 2014 12:26:03 +0530 From: Preeti U Murthy <preeti@...ux.vnet.ibm.com> To: mpe@...erman.id.au, mikey@...ling.org, joel.stanley@....ibm.com Cc: benh@...nel.crashing.org, linuxppc-dev@...ts.ozlabs.org, rjw@...ysocki.net, linux-kernel@...r.kernel.org Subject: [PATCH] cpuidle/powernv: Re-enable fastsleep at boot time Commit dcb18694 "Fix ipi on palmeto" disabled fastsleep at boot time. Revert this commit since we no longer need this fix. However we can continue to use powersave_nap parameter to control entry into deep idle states beyond snooze. Signed-off-by: Preeti U.
