-Subject: arm64: Ensure the instruction emulation is ready for userspace
-
-We trap and emulate some instructions (e.g, mrs, deprecated instructions)
-for the userspace. However the handlers for these are registered as
-late_initcalls and the userspace could be up and running from the initramfs
-by that time (with populate_rootfs, which is a rootfs_initcall()). This
-could cause problems for the early applications ending up in failure
-like :
-
-[   11.152061] modprobe[93]: undefined instruction: pc=0000ffff8ca48ff4
-
-This patch promotes the specific calls to core_initcalls, which are
-guaranteed to be completed before we hit userspace.

-Subject: arm64: Ensure fpsimd support is ready before userspace is active
-
-We register the pm/hotplug callbacks for FPSIMD as late_initcall,
-which happens after the userspace is active (from initramfs via
-populate_rootfs, a rootfs_initcall). Make sure we are ready even
-before the userspace could potentially use it, by promoting to
-a core_initcall.
