Subject[PATCH 3.16 44/63] arm64: support keyctl() system call in 32-bit mode
3.16.81-rc1 review patch.  If anyone has any objections, please let me know.


From: Eric Biggers <>

commit 5c2a625937ba49bc691089370638223d310cda9a upstream.

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.
