[PATCH] arm64: support keyctl() system call in 32-bit mode

From: Eric Biggers
Date: Wed Mar 08 2017 - 20:35:37 EST

From: Eric Biggers <ebiggers@xxxxxxxxxx>

As is the case for a number of other architectures that have a 32-bit
compat mode, enable KEYS_COMPAT if both COMPAT and KEYS are enabled.
This allows AArch32 programs to use the keyctl() system call when
running on an AArch64 kernel.
