arm64: Fix CONFIG_ARCH_RANDOM=n build

2020-02-11T09:47:01+00:00

The entire asm/archrandom.h header is generically included via linux/archrandom.h only when CONFIG_ARCH_RANDOM is already set, so the stub definitions of __arm64_rndr() and __early_cpu_has_rndr() are only visible to KASLR if it explicitly includes the arch-internal header.

arm64/spinlock: fix a -Wunused-function warning

arm64: ssbs: Fix context-switch when SSBS is present on all CPUs

2020-02-10T11:29:02+00:00

When all CPUs in the system implement the SSBS extension, the SSBS field in PSTATE is the definitive indication of the mitigation state. Further, when the CPUs implement the SSBS manipulation instructions (advertised to userspace via an HWCAP), EL0 can toggle the SSBS field directly and so we cannot rely on any shadow state such as TIF_SSBD at all. Avoid forcing the SSBS field in context-switch on such a system, and simply rely on the PSTATE register instead.
