I just realized this isn't complete.  You're not testing for
PPC_FEATURE_ARCH_2_07 which is stored in hwcap2/h2.  So I guess
this should look like:

if (h2 & PPC_FEATURE_ARCH_2_07)
  h1 |= PPC_FEATURE_ARCH_2_06
	| PPC_FEATURE_ARCH_2_05 
	| PPC_FEATURE_POWER5_PLUS 
	| PPC_FEATURE_POWER5 
	| PPC_FEATURE_POWER4;
else if (h1 & PPC_FEATURE_ARCH_2_06)
  h1 |= PPC_FEATURE_ARCH_2_05 
	| PPC_FEATURE_POWER5_PLUS 
	| PPC_FEATURE_POWER5 
	| PPC_FEATURE_POWER4;
else if (h1 & PPC_FEATURE_ARCH_2_05)
  h1 |= PPC_FEATURE_POWER5_PLUS 
	| PPC_FEATURE_POWER5 
	| PPC_FEATURE_POWER4;
else if (h1 & PPC_FEATURE_POWER5_PLUS)
  h1 |= PPC_FEATURE_POWER5 
	| PPC_FEATURE_POWER4;
else if (h1 & PPC_FEATURE_POWER5)
  h1 |= PPC_FEATURE_POWER4;
