-Subject: [PATCH 245/296] x86: crypto: Reduce preempt disabled regions
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.35-rt39.tar.xz
-
-Restrict the preempt disabled regions to the actual floating point
-operations and enable preemption for the administrative actions.
-
-This is necessary on RT to avoid that kfree and other operations are
-called with preemption disabled.
