Users cannot disable multiple CPU features with the kernel parameter clearcpuid=. For example, "clearcpuid=154 clearcpuid=227" only disables CPUID bit 154. Previous to commit 0c2a3913d6f5 ("x86/fpu: Parse clearcpuid= as early XSAVE argument") it was possible to pass multiple clearcpuid options as

Add a "create" module parameter, which allows device-mapper targets to be configured at boot time. This enables early use of dm targets in the boot process (as the root device or otherwise) without the need of an initramfs. The syntax used in the boot param is based on the concise format from the
