[committed, PATCH] [BZ #20119] Correct Intel processor level type mask from CPUID

[H.J. Lu]

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.

Tested on x86.  Checked in.

	[BZ #20119]
	* sysdeps/x86/cacheinfo.c (init_cacheinfo): Correct Intel
	processor level type mask for CPUID with EAX == 11.
