Correct Intel processor level type mask from CPUID
Intel CPUID with EAX == 11 returns: ECX Bits 07 - 00: Level number. Same value in ECX input. Bits 15 - 08: Level type. ^^^^^^^^^^^^^^^^^^^^^^^^ This is level type. Bits 31 - 16: Reserved. Intel processor level type mask should be 0xff00, not 0xff0. [BZ #20119] * sysdeps/x86/cacheinfo.c (init_cacheinfo): Correct Intel processor level type mask for CPUID with EAX == 11.
