            Bug ID: 20119
           Summary: Wrong mask for processors level type from CPUID
           Product: glibc
           Version: 2.24
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

X86 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.

But cacheinfo.c has

                 int shipped = ebx & 0xff;
                  int type = ecx & 0xff0;
                             ^^^^^^^^^^^^  The mask should be 0xff00
                  if (shipped == 0 || type == 0)
                    break;
