+Subject: [PATCH 047/347] arm*: disable NEON in kernel mode
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+NEON in kernel mode is used by the crypto algorithms and raid6 code.
+While the raid6 code looks okay, the crypto algorithms do not: NEON
+is enabled on first invocation and may allocate/free/map memory before
+the NEON mode is disabled again.
+This needs to be changed until it can be enabled.
+On ARM NEON in kernel mode can be simply disabled. on ARM64 it needs to
+stay on due to possible EFI callbacks so here I disable each algorithm.
