Subject: arm64: support keyctl() system call in 32-bit mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c2a625937ba49bc691089370638223d310cda9a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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

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.
