Subject: [PATCH]:x86_64: Change assembly to use regular cpuid_count macro
Date: Wed, 24 May 2006 15:25:22 -0700 [thread overview]
Message-ID: <1148509522.14025.7.camel@galaxy.corp.google.com> (raw)
Minor cleanup patch:
Replacing the asm statement with cpuid_count macro(which already
provides the same functionality).
