Sachin Sant 1867859184 selftests/powerpc: skip tests for unavailable mitigations. ... Mitigation patching test iterates over a set of mitigations irrespective of whether a certain mitigation is supported/available in the kernel. This causes following messages on a kernel where some mitigations are unavailable: Spawned threads enabling/disabling mitigations ... cat: entry_flush: No such file or directory cat: uaccess_flush: No such file or directory Waiting for timeout ... OK This patch adds a check for available mitigations in the kernel.
