Re: [PATCH] Common cpuid wrappers, use SYS_cpuid when available


Sorry for the malformed patch in the first post.
Here is a working one.

	* config.h.in: Check for SYS_cpuid and define HAVE_SYS_CPUID
	* configure: Check for SYS_cpuid and define HAVE_SYS_CPUID
	* configure.ac: Check for SYS_cpuid and define HAVE_SYS_CPUID
	* misc/cpuid.h: Common cpuid wrappers, use SYS_cpuid when available
	* sysdeps/x86/cpu-features.c: Use misc/cpuid.h wrappers
	* sysdeps/x86/fpu/test-fenv-clear-sse.c: Use misc/cpuid.h wrappers
	* sysdeps/x86/fpu/test-fenv-sse-2.c: Use misc/cpuid.h wrappers
	* sysdeps/x86/fpu/test-fenv-sse.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/cacheinfo.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-audit10.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-audit4.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-audit6.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-auditmod10b.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-auditmod4b.c: Use misc/cpuid.h wrappers
	* sysdeps/x86_64/tst-auditmod6b.c: Use misc/cpuid.h wrappers
