-Subject: [PATCH] Add 32 bit compatible rdtsc asm
-
-Gcc's inline asm constraints have different meanings on x86_64 and ia32.
-Include a 32 bit version for the rdtsc function. Drop the empty 32 bit
-version of time_usec as it and the cpuid function both function properly
-when compiled for 32 bit systems.
-
-Tested on the following CPU:
-Intel(R) Atom(TM) CPU E640 @ 1.00GHz
-
-A value of 1000000000 was detected.
-
-Signed-off-by: Darren Hart <dvhart@linux.intel.com>
