[PATCH V7 41/41] x86/intel_rdt: Simplify index type

From: Reinette Chatre
Date: Fri Jun 22 2018 - 18:49:31 EST


From: Ingo Molnar <mingo@xxxxxxxxxx>

Simplify this pattern:

#ifdef CONFIG_X86_64
u64 i;
#else
u32 i;
#endif

... to the more natural and shorter one:

unsigned long i;

No change in functionality.
